@5 Speaker Jacks (SPEAKER 1, 2 (EXT))

Two Speaker Jacks are provided for connecting speaker systems.

The amp’s internal speaker (4 Ω) is connected to the SPEAKER 1 jack.

The SPEAKER 2 (EXT) jack can be used to add an external speaker(s).

Also, if necessary, you can disconnect the internal speaker to connect 2

external speakers directly to the amp.

The two speaker jacks are connected in parallel. When external speak-

ers are used, make sure the speakers meet the following requirements.

● When using a single SPEAKER Jack (1 or 2)

Please use a system that complies with one of the following re-

quirements.

• The total impedance* of the circuit should never be less than 2Ω.

•A 2Ω speaker system must have a power handling capability of

500W or greater.

•A 4Ω speaker system must have a power handling capability of

250W or greater.

• An 8Ω speaker system must have a power handling capability of

125W or greater.

● When using both SPEAKER Jacks (1 & 2)

Please use a system that complies with one of the following re-

quirements.

• The total impedance* of the circuit should never be less than 2Ω.

•A 4Ω speaker system must have a power handling capability of

250W or greater.

• An 8Ω speaker system must have a power handling capability of

125W or greater.

To obtain optimum performance from the amplifier, we recommend con-

necting the internal speaker to the SPEAKER 2 jack, and using the

SPEAKER 1 jack to connect an external speaker (set) with a 4Ω imped-

ance and power handling capacity of 250W or greater.

* See page 10 for more information on total speaker impedance.

* For U.S. and Canadian models only

To protect against electromagnetic waves, attach the sup-

plied Clamp Filters to the cables connecting the amplifier’s

SPEAKER 1, 2 (EXT) jacks to the speakers. (→ pg. 10)

@6 Tweeter Level Control (TWEETER LEVEL)

This controls the built-in tweeter speaker’s output level (mainly high fre-

quencies above 4 kHz).

@7 Power Connector (AC IN)

Connect the supplied power cable to this terminal to supply the unit with

power from an AC power outlet.

When connecting the power cable, make sure the

amplifier’s POWER switch is turned OFF.

● Connected in Parallel

Total impedance =

Connecting three 4Ω speaker cabinets in a parallel configuration

as shown below, results in a total impedance of about 1.3Ω.

Panel Controls and Connections

* Total Impedance

Whenever two or more speaker cabinets are connected to the unit, consideration must be given to the total impedance of the

speaker system.

Normally, a speaker cabinet has an impedance of 4, 8 or 16Ω. But when two or more speaker cabinets are used together, the total

impedance will change according to the manner in which the cabinets are connected.

● Connecting in a Series

Total impedance = 1st Speaker + 2nd Speaker + 3rd Speaker …

Connecting three 4Ω speaker cabinets in a series as shown below,

results in a total impedance of 12Ω.

As the BBT500-115’s and BBT500-110’s two speaker jacks are

connected in a parallel circuit inside of the amplifier, adding a 4Ω

external speaker to the 4Ω internal speaker will result in a total

impedance of 2Ω. So in order to maintain a minimum impedance of

2Ω, an external speaker with an impedance of 4Ω or greater must

be used.

Internal Speaker

4 Ω

External Speaker

Greater than 4 Ω

Cable

Clamp Filter

● Attaching the Clamp Filter (For U.S. and Canadian models only)

To protect against electromagnetic waves, attach the supplied Clamp Filter to the cable connecting the bass guitar to the amplifier’s

INPUT jack, and to the cable connecting the amplifier to an external speaker.

*The cable connecting the internal speaker (SPEAKER 1 jack) is fitted with a Clamp Filter at the factory.

*When attaching the clamp filter, wrap the cable once around the clamp filter as close to the BBT500 unit as possible.

Sound Setting

When the power is switched ON, all control knobs function as labeled

on the panel and described below. All lamps on the display above the

control knobs and switches are unlit.

Rotate the SOUND TYPE knob to select a sound type, then use the

Tone Control knobs to shape the sound. Before selecting a sound type,

first set the GAIN through TREBLE control knobs to their center posi-

tions then try out the different Sound Types.

Also, the COMP knob is used to adjust the compressor’s compression

ratio. The compressor automatically balances the differences between

loud and soft levels when playing. Rotate the knob to the right to in-

crease the amount of compression.

e COMP: Compression Ratio (1.0 to ∞, 16 steps)

This adjusts the compressor’s compression ratio and output levels simul-

taneously.

As the value increases, so does the amount of compression applied to

signals that exceed the threshold level (→ pg. 14).

r GAIN: Pre-Amp Gain (0 to 10, 0.1 step)

t MASTER: Master Volume (0 to 10, 0.1 step)

y BASS: Bass Frequency (-15dB to +15dB, 0.2dB step)

i MIDDLE: Middle Frequency (-15dB to +15dB, 0.2dB step)

o HIGH MID: High mid Frequency (-15dB to +15dB, 0.2dB step)

!0 TREBLE: Treble Frequency (-15dB to +15dB, 0.2dB step)

!1 OUTPUT: Sets the output level

Getting sound output

1 First, make sure that the POWER switch is switched OFF, then

connect your bass to the INPUT Jack on the front panel.

2 Rotate the OUTPUT knob fully to the left and then switch the

POWER switch ON.

To protect the speakers, make sure that the

OUTPUT knob is set to “0” whenever switch-

ing the POWER switch ON or OFF.

Operating Instructions

w e r t y u i o !0 !1

3 First, set the INPUT LEVEL knob to its 12 O’clock position, then

while playing the bass, gradually increase the GAIN, MASTER,

and OUTPUT knobs to adjust the sound.

4 Once the system is producing sound, set the input level as

described in the “Adjusting the Input Level” section below.

Set the knob so that the red

indicator does not light.

Adjusting the Input Level

The INPUT LEVEL control optimizes the signal received from the bass

for use with the amplifier, to produce wide dynamic range and rich tone.

A poorly adjusted level results in noise, feedback, a cutup sound, etc.

* Since output levels vary from instrument to instrument, you will need to

readjust the input level to match the instrument’s output level whenever

you change instruments.

1 Rotate the volume control on your bass to its maximum level

and play loudly while rotating the INPUT LEVEL knob.

An ideal level is attained when the green indicator is lit.

2 Continue to rotate the INPUT LEVEL knob to the right making

sure the red indicator does not light. As long as the red indica-

tor does not light, rotate the knob fully to the right.

HINT Using the OUTPUT and MASTER Controls

Both knobs can be used to control the overall volume however, the

MASTER knob is the preamplifier’s master volume and its setting is

saved in memory. The OUTPUT knob is the power amplifier’s output

volume and its setting is not saved in memory. Use the MASTER knob

to set individual volume settings of patches saved to memory, and use

the OUTPUT knob to set the output volume level produced by the speak-

ers.

Operating Instructions

Setting Value

The value “4.0” flashes on the display

but rotating the knob from the “3

o’clock” position to the “11 o’clock”

position does not change anything.

As the knob goes past the “11

o’clock” position and its position

matches that of the value, the

value will then stop flashing and

start changing according to the

knob’s position.

Storing and Recalling Patches

After creating a sound that you like, you can store its settings in the

unit’s internal memory. Sound setting data (individual knob settings) is

called a Patch. Saving a patch to the unit’s internal memory is called

Store.

The BBT500 provides five memory locations for storing patch data.

Patch data in the memory is stored even when the power is switched

OFF, and can be recalled at any time by pressing the patch’s corre-

sponding switch. Take note that unless the changes are saved to memory,

any changes made to the patch will be lost when another patch is se-

lected or when the power is switched OFF.

Storing a Patch

After creating a sound you want to keep for later use, press and hold

any one of the Memory Switches (1-5) until all of the front panel indica-

tors light.

Ex.) Press and hold Memory Switch [1] until all indicators light.

* INPUT LEVEL and OUTPUT LEVEL settings are not stored in memory.

Recalling a Patch

To use one of the patches stored in memory, just press the Memory

Switch [1]-[5] to which the data is stored.

The indicator of the selected Memory Switch lights.

Ex.) Recalling the patch stored to Memory Switch [2].

● Knob Position and Settings

When a patch is recalled from memory, etc., it may be that the

knob’s actual position differs from the value set in the recalled

patch.

In this case, the BBT500 is programmed to flash the patch’s

value on the display without changing it or the sound until the

knob’s position corresponds to the value in the recalled patch

setting.

If the display flashes when rotating the knob, continue rotating

the knob until its position matches the flashing value. When the

position and value match, the value will stop flashing on the

display and change as the knob is turned.

Ex.) If the GAIN knob is pointing at the “3 o’clock” posi-

tion and a patch with a GAIN setting of 4.0 is recalled.

After you recall or store a patch, the value for each knob will appear in

the display when the knob (COMP - TREBLE) is used.

However, if the value set in the patch is different than the knob’s actual

position, the patch’s value will flash in the display but it will not change,

nor will the sound, even though you are turning the knob. For more infor-

mation on this situation, refer to the “Knob Position and Settings” sec-

tion below.

● The Useful “Undo” Function

Press and hold the [MANUAL] switch activates the “Undo” func-

tion, which returns settings to the condition they were in prior to

pressing a Memory Switch [1]-[5] or the [MANUAL] switch.

This function is useful in cases such as:

You’ve just made some changes to the patch saved in Memory

Switch [1] but pressed Memory Switch [2] before you could save

the changes to memory. Press and hold the [MANUAL] switch to

return the settings to the same condition they were in before you

pressed Memory Switch [2].

In the same manner, you made some changes to a patch but

pressed the [MANUAL] switch before you could save those

changes to memory. Press and hold the [MANUAL] button to re-

store your changes.

The BBT500 also features more precise settings for defining the fre-

quencies for each of the Tone Control knobs, operating the Compressor

and Noise Gate, or setting the Blend Level of the effect loop, etc.

To access these settings, press the [FUNCTION] switch and use the

four Modes described below.

• Amp Mode

In this mode, each knob functions in the manner it is labeled on the

front panel.

• Equalizer Mode

This mode is used to set the 1-band parametric equalizer and the

center frequency for each of the Tone Controls (Bass – Treble).

• Compressor Mode

This mode is used to set the Compressor’s blend level, noise gate

level, and effect loop.

• Utility Mode

This mode is used to set the crossover filter, and individual MIDI

settings.

Individual settings in the Amp Mode, Equalizer Mode, and Compressor

Mode are saved when patch data is saved to the unit’s memory.

Individual parameter settings in the Equalizer Mode and Compressor

Mode are set to their default values when the power is switched ON.

Individual settings in the Utility Mode are saved when exiting the Utility

Mode, and they are retained even if the power is switched OFF.

Detailed Parameter Settings

Amp Mode

Each knob functions in the manner it is labeled on the panel.

In the Amp Mode, the knob’s value (or patch’s setting value) is shown

on the display when the knob is turned.

* After the BBT500’s power is switched ON or the [MANUAL] switch is

pressed, nothing is shown in the display until a Memory is recalled, or a

mode other than the Amp Mode is selected.

Enter the Amp Mode using one of the following methods.

• The Amp Mode is the default mode when the BBT500’s power is

switched ON.

• Press the [MANUAL] Switch to enter the Amp Mode.

• Press a Memory Switch [1] – [5] to recall a patch. Or, press and

hold a Memory Switch to save a patch to memory.

• In the Equalizer, Compressor, or Utility Mode, press the [FUNC-

TION] switch.

● How Knobs Function in the Amp Mode

The knob’s value is shown on the display

when the knob is turned.

i MIDDLE: Middle Frequency (-15dB to +15dB, 0.2dB step)

o HIGH MID: High mid Frequency (-15dB to +15dB, 0.2dB step)

!0 TREBLE: Treble Frequency (-15dB to +15dB, 0.2dB step)

!1 OUTPUT: Sets the output level

Compressor Mode

The Compressor Mode provides settings for the Compressor, Noise Gate,

and Blend Level for the effect loop.

To enter the Compressor Mode, press and hold the [FUNCTION] switch

until the knob functions are displayed in the upper row of the panel dis-

play above the knobs (the row above that used by the Equalizer Mode).

● How Knobs Function in the Compressor

Mode

q INPUT LEVEL: Sets the Input Level

w SOUND TYPE: No function.

e COMP (RATIO): Compression ratio (1.0 - ∞, 16 steps) *operates the same

as COMP in the Amp Mode.

r GAIN (THRSLD): Compressor threshold level (-54dB to 0dB, 1dB step)

Sets the signal level from which the compressor will activate. Compres-

sion is applied to signals that exceed this level.

t MASTER (ATTACK): Compressor attack time (0msec to 120msec, 1msec

step).

Sets the amount of time required for application of the compressor from

the time the signal exceeds the threshold. When a slow attack time is set,

the beginning of the attack will not be compressed.

y BASS (RELEASE): Compressor release time (5msec to 42.3 sec, 160

steps).

Sets the amount of time required for the compressor to switch off after the

signal goes below the threshold level. This smoothes gain changes to

keep the sound natural.

u LOW MID (C. GAIN): Compressor gain (0dB to 18dB, 0.1dB step)

This parameter works in conjunction with the compressor ratio setting

which is set with the e COMP (RATIO) control knob. In other words, gain

is automatically adjusted along with amount of compression applied to

the signal. If the Ratio = “1.0”, Gain = “0”. If the Ratio = “∞”, Gain = the

setting determined with the control knob.

i MIDDLE (KNEE): Compressor knee (Hd (Hard), 1, 2, 3, 4, 5)

Sets the depth of signal compression after the input signal exceeds the

threshold level. When set to Hd (hard), compression starts soon with the

ratio you have set. However, when set to 1-5, compression startup is

gradual, creating a more natural sound (soft knee compression).

o HIGH MID (N. GATE): Noise gate threshold level (OFF, -53dB to 0dB,

1dB step)

When the input signal’s level falls below this set level, the noise gate acti-

vates cutting off the signal.

!0 TREBLE (BLEND): Blend level between the effect loop’s RETURN signal

and the dry signal (the sound created in the BBT500) (0% (Return 0%,

Dry 100%) to 100% (Return 100%, Dry 0%)).

Settings

Crossover Filter

By connecting two BBT500s as shown in the illustration below, you can

create a bi-amplified system, where one amplifier is used to drive high

frequencies and a second amplifier drives low. This system uses the

amplifier’s onboard crossover filter (LPF or HPF) to determine the range

of frequencies that each amplifier will deliver.

● Setting the Crossover Filter

1 Press and hold the [FUNCTION] switch for more than three sec-

onds (until “utL” appears on the display) to enter the Utility

Mode.

2 Rotate the COMP knob to set the Crossover filter’s cutoff fre-

quency.

* Range of cutoff frequency

L10 (LPF 100Hz) to L00 (LPF 1000Hz), byP (Bypass),

h10 (HPF 100Hz) to h00 (HPF 1000Hz), 93 steps

When using a bi-amplified system, make sure

that the INPUT LEVEL control knob on the

second BBT500 is set to its minimum level.

Ex.) Operating a bi-amplified system in which the crossover fil-

ter on the first amplifier is set to h50 (HPF 500Hz) to pro-

duce high frequencies, and the crossover filter on the sec-

ond amplifier is set to L50 (LPF 500Hz) to produce low fre-

quencies.

Utility Mode

The Utility Mode provides settings for the Crossover Filter and MIDI.

These settings are saved internally when you exit the Utility Mode and

kept even when the amplifier’s power is switched OFF.

● Entering the Utility Mode

To enter the Utility Mode, from any mode press and hold the [FUNC-

TION] switch for more than 3 seconds, until “utL” appears on the dis-

play.

● How Knobs Function in the Utility Mode

In the Utility Mode, only the INPUT LEVEL, OUTPUT, and COMP knobs

function. All other knobs (SOUND TYPE, GAIN - TREBLE) have no func-

tion.

• INPUT LEVEL: Sets the Input Level

• OUTPUT: Sets the output level

• COMP: Sets the cut off frequency of the crossover filter

When the COMP knob is used (when setting the crossover filter), the

setting’s value is shown in the display. Other than that, only utL ap-

pears on the display.

Detailed Parameter Settings

MIDI Settings

The BBT500 is MIDI* compatible and equipped with MIDI IN and MIDI

OUT jacks.

* What is MIDI?

The acronym for Musical Instruments Digital Interface, MIDI is a world-

wide standard communication interface that allows MIDI compatible mu-

sical instruments, computers, and other MIDI devices to share musical

information and control one another regardless of instrument type or

maker.

With MIDI functions you can do things like select a patch from the

BBT500’s memory using an external MIDI device like the MFC10 Yamaha

MIDI Foot Controller, etc. You can also backup data by sending the con-

tents in the unit’s memory to a device that is capable of saving MIDI

data (Yamaha MDF3, etc.).

● Selecting a Patch with MIDI

1 Using a MIDI cable, connect the MIDI IN jack on the BBT500 to

the MIDI OUT jack on the external MIDI device.

* Use only a standard MIDI cable that is less than 15 meters in length. Use

of a longer cable can result in trouble such as abnormal operation, etc.

2 Set the MIDI receive channel on the BBT500 and the MIDI trans-

mit channel on the external device to the same MIDI channel.

(Default channel: 1)

* MIDI data can not be transmitted or received if the MIDI channels are

not properly matched.

2-1 Press and hold the [FUNCTION] switch for more than three

seconds (until “utL” appears on the display) to enter the

Utility Mode.

2-2 While holding the [MANUAL] switch, press Memory Switch [3].

(Default

→→

→ Program Change No: Memory No = 1:1, 2:2, 3:3, 4:4,

5:5, 6:1, 7:2, 8:3 …)

* What is a Program Change Map?

A Program Change Map assigns a program change number (re-

ceived via MIDI) to a memory number. For example, when the

BBT500 receives “Program Change Number 1” from an external

MIDI device, it will recall memory number “3”. This is also called a

Program Change Table.

3-1 Press and hold the [FUNCTION] switch for more than 3 sec-

onds (until “utL” appears on the display) to enter the Utility

Mode.

3-2 While holding the [MANUAL] switch, press Memory Switch [1].

The currently assigned MIDI program change number appears

on the display (after a few seconds, the display will return to

“utL”).

3-3 Use Memory Switches [1] and [2] to set the program change

number (1-128) that is received by the BBT500.

Use Memory Switch [2] to increase the value and Memory

Switch [1] to decrease the value.

3-4 While holding the [MANUAL] switch, press Memory Switch [2].

The memory number that will be recalled when the program

change number that was set in step 3-3, appears on the dis-

play. (After a few seconds, the display will return to “utL”).

3-5 Use Memory Switches [1] and [2] to set the memory number

(1-5) that corresponds to the program change number re-

ceived by the BBT500.

Uses Memory Switch [2] to increase the value and Memory

Switch [1] to decrease the value.

3-6 If necessary, repeat steps 3-2 through 3-5.

3-7 Press the [FUNCTION] switch to enter the Amp Mode.

4Now, when a program change number transmitted from an ex-

ternal MIDI device is received by the BBT500, it will recall the

corresponding memory number that is set in the program

change map you just created will be recalled.

* Refer to the Owner’s Manual that came with your MIDI device on how

to receive or transmit program change data.

4 Press the [FUNCTION] switch to enter the Amp Mode.

● MIDI Bulk Out

You can use the MIDI Bulk Out operation to back up data saved in the

BBT500 (data in memory 1-5 and Utility Mode settings) to a device that

can save MIDI data (such as a Yamaha MDF3, etc.).

1 Using a MIDI cable, connect the MIDI OUT jack on the BBT500

to the MIDI IN jack on an external MIDI device.

* Use only a standard MIDI cable that is less than 15 meters in length. Use

of a longer cable can result in trouble such as abnormal operation, etc.

2 Hold the [FUNCTION] switch for more than three seconds (un-

til “utL” appears on the display) to enter the Utility Mode.

● About MIDI Control Changes

You can control the overall volume of the BBT500 by connect-

ing an external MIDI device’s MIDI OUT jack to the BBT500’s

MIDI IN jack, and transmit Number 7 Control Change Mes-

sages (Main Volume) to the BBT500.

*With the exception of the Number 7 Control Change, the BBT500

does not recognize any other MIDI Control Change messages.

*The Main Volume data will not change, even if a different memory

number is selected.

*When the POWER is switched ON, the Main Volume data is set

to its MAX value.

After the Main Volume data is changed, and the external MIDI device

is disconnected, the pre-amp’s volume level may not be sufficient. If

this case occurs, transmit a Control Change with a higher volume

setting again, or switch the POWER OFF and then back ON.

● About MIDI Bulk In

Using a MIDI cable, connect the MIDI IN jack on the BBT500 to

the MIDI OUT jack on an external MIDI device to return data

that has been stored on the external device, to the BBT500’s

memory. This operation is referred to as MIDI Bulk In.

*The device number becomes the MIDI receive channel number

(→ pg. 15). When the MIDI receive channel is set to “ALL” (Omni

ON), the channel is set to 1. When set to “oFF” (OFF) data will

not be received.

* “Ld” appears on the display while receiving MIDI Bulk data.

● Sending/Receiving MIDI Data Between

Two BBT500s

The MIDI Bulk In or MIDI Bulk Out operations can be used to

copy memory or Utility Setup data in one BBT500 to another

BBT500.

● Restoring the Factory Presets

This operation clears the contents

of the BBT500’s memory 1-5 and

restores all parameters to their

factory preset settings.

While holding the [MANUAL]

switch and Memory Switch [5],

switch the POWER switch ON.

Error Messages

Troubleshooting

• No Sound

→ Is the power cord properly connected to the device?

→ Is the volume turned up on the instrument connected to the INPUT jack?

→ Are the INPUT LEVEL, GAIN, MASTER, OUTPUT control knobs set to “0”?

→ Check the Effect Loop’s BLEND setting (Compressor Mode: TREBLE control knob). Unless an external effector is connected

to the device, raising the BLEND control will result in lowering the original sound. If the BLEND control is set to “100”, the

original sound will not be produced.

• Sound output is low

→ Is the volume turned up on the instrument connected to the INPUT jack?

→ Are the INPUT LEVEL, GAIN, MASTER, OUTPUT control knobs turned up?

→ Check the Effect Loop’s BLEND setting (Compressor Mode: TREBLE control knob). Unless an external effector is connected

to the device, raising the BLEND control will result in lowering the original sound. If the BLEND control is set to “100”, the

original sound will not be produced.

→ Check the Compressor setting. A low Threshold setting or a high Ratio setting will result in a lowered the output signal level.

Also, a long release setting or low Compressor Gain setting will result in a lowered output signal level.

Air Flow
