Introduction

Terms

This section explains terminology speciﬁc to the ACD1.

■ Amp Editor

This is computer application software. With this software, you can use your computer to monitor and control the ACD1 and

the ampliﬁers connected to the ACD1.

■ Scene

Settings such as Power-On/Standby or mute for each ampliﬁer are collectively called a “scene.” By recalling a scene, the

saved settings can be immediately applied to the ampliﬁers. The ACD1 can specify 49 scenes for each connected ampliﬁer.

■ Scene link

Settings for simultaneously recalling scenes for multiple ampliﬁers within an area are called a “scene link.” By recalling a

scene link, scenes can be simultaneously recalled for multiple ampliﬁers. Scene links can be created and recalled using

Amp Editor.

■ Device ID

This is an ID for uniquely identifying an ACD1 unit within a network. If there are duplicate IDs within an area, it will be

impossible to monitor/control them from Amp Editor.

■ Amp ID

This is the ID of each ampliﬁer connected to the ACD1. Ampliﬁers connected to the [DATA PORT] connector of the same

ACD1 must be set to non-overlapping IDs using the [AMP ID] switch located on the rear panel of each ampliﬁer. For ampli-

ﬁers connected to a [MONITOR/REMOTE] connector, the Amp ID is determined by the connector that is used.

ACD1 Reference Manual

Controls and Connectors

q Display

This shows information about the scene, the ACD1 itself, or the connected ampliﬁers. This will light red when an abnormal-

ity (a WARNING or higher alert) occurs. This will also blink blue and white when the Identify operation is performed in

Amp Editor.

When you turn on the power, a HOME screen like the following will appear. The HOME screen shows the Device ID and

the name of the ACD1 speciﬁed by Amp Editor.

w [BACK] button

Use this to move to the previous screen or parameter.

• If you press and hold down this button for three seconds or longer while the HOME screen is displayed, the Device ID

setting screen will appear.

e [▲INC/YES]/[▼DEC/NO] buttons

Use these to increment or decrement (INC/DEC) the value of a parameter, or to respond YES/NO to a conﬁrmation mes-

sage.

•To temporarily unlock the panel operation, press and hold down both the [▲INC/YES] and [▼DEC/NO] buttons for at

least three seconds to display the message “Unlock panel: Are you sure?”. Press the [▲INC/YES] button. The panel lock

will be temporarily defeated until the power to the ACD1 is turned off.

•To reset the FAULT OUTPUT connector output (to connect NC and C), press and hold down the [BACK] and [▼DEC/NO]

buttons simultaneously for a few seconds while the HOME screen is displayed to display the message “Reset FaultOut

Are you sure?”. Then press the [▲INC/YES] button. This operation is effective only when the FAULT OUTPUT connector

indicates an abnormality.

r [NEXT] button

Use this to move to the next screen or parameter.

t [POWER ON/OFF] button

Turns mains power to the ACD1 on and off.

• The settings at the time you powered-off are remembered. When you turn on the power again, the unit will start up with

the same settings. You can use the “Last Mem. Resume” setting to set up the unit so that at startup it will recall the scene

number selected before you turned off the power to the device.

• If Last Mem. Resume is ON, data will be backed-up to internal memory at regular intervals, so you should not turn off the

power within ﬁve seconds after operating a parameter.

• Do not turn off the power while the display indicates “Do not turn off!”

CAUTION

ACD1 Reference Manual

Controls and Connectors

y Ground screw

The AC power cord is a 3-wire type. If the AC outlet used is earthed (grounded), this device will be properly earthed as well.

Also, grounding the screw sometimes reduces hum and interference noise.

u [AC IN] connector

Connect to the AC mains using the supplied AC power cable.

First connect the power cord to the ACD1, then insert the power cord plug into an AC outlet.

i [NETWORK] connector

This is a 100Base-TX/10Base-T Ethernet connector for connection to a computer or other device in the network.

• Use a UTP cable or STP cable for connection to the [NETWORK] connector. (Use an STP cable in countries where FCC

regulations apply.) Since the ACD1 supports Auto MDI/MDI-X, it will automatically detect whether the connected cable is

of the straight type or crossover type, and will conﬁgure itself to create the appropriate connection. Therefore, you can

use either a straight or crossover cable.

• The maximum length of a cable between a network switch and the ACD1 is 100 meters. Due to the quality of cables and

network switch performance, however, proper operation at the maximum length cannot be guaranteed in some cases.

o [GPI] connector

This Euroblock connector provides access to the unit’s GPI (General Purpose Interface) interface for transfer of control sig-

nals to and from external equipment. The ACD1 provides 4-port input and 4-port output. The +V terminals have an output

voltage of 5 volts. The IN terminals detect voltage changes from 0V to 5V. The OUT terminals are open-collector outputs,

and change between Open and Close. For details on connections and usage, refer to “Connector wiring” (page 18). For

details on calibrating the [GPI IN] connectors, refer to “Utility” (page 13).

!0 [FAULT OUTPUT] connectors

This is a Euroblock connector that can inform an external device when an abnormality occurs with the ACD1’s CPU, or

when there is an event for which Fault Output has been speciﬁed in the Alert Setup dialog box of Amp Editor. For details on

connections and usage, refer to “Connector wiring” (page 18).

!1 [DATA PORT] connector

This is an RJ-45 connector that can be connected to a maximum of 32 PC-N/Tn series units so that they can be monitored/

controlled from the ACD1. You can use CAT5 or better UTP straight cables to make daisy-chain connections for a maxi-

mum of 500 meters.

The Amp ID of ampliﬁers connected to this connector must be set to non-overlapping numbers in the range of 0 to 31.

• Use a UTP cable in which all eight pins are connected.

!2 [MONITOR/REMOTE] connector

These are D-Sub 15-pin connectors that allow up to eight XP/XH/XM series units to be connected so that they can be mon-

itored/controlled from the ACD1. You can use three-row D-Sub 15-pin straight cable to make a connection for a maximum

of 50 meters.

Ampliﬁers connected to these connectors will be assigned an Amp ID between 32 and 39 according to the connector to

which they are connected.

Here’s how to recall or store scenes for a speciﬁed ampliﬁer.

■ Recalling a scene (“1. Scene” ➝ “Recall”)

Recalls a scene for the speciﬁed ampliﬁer.

• If you select “ALL” as the Amp ID, the scene name will not be displayed.

• If you select “ALL” as the Amp ID, ampliﬁers for which there is no correspondingly-numbered scene data will not recall a

scene; they will retain their previous state.

• Scene number 00 is for returning the ampliﬁers to their default settings.

• If characters not supported by the ACD1 were used for the scene name in Amp Editor, the corresponding locations will

be shown as “~.” For details on the characters supported by the ACD1, refer to “List of supported characters” (page 21) at

the end of this manual.

• Scene names that can be displayed by the ACD1 are a maximum of 12 characters. If a scene name of 13 characters or

longer is speciﬁed in Amp Editor, the ACD1 will not display the thirteenth and subsequent character.

• If you edit a parameter after recalling a scene, the E symbol (edit symbol) will be shown in screens that show the scene

number.

■ Storing a scene (“1. Scene” ➝ “Store”)

Stores a scene for the speciﬁed ampliﬁer.

• If the screen indicates “(scene number):(scene name) Overwrite?”, scene data has already been stored in the selected

scene. If you want to overwrite the existing data, press the [▲INC/YES] button. If you want to store the settings to a dif-

ferent scene number without overwriting, press the [▼DEC/NO] button, then press the [BACK] button several times,

and re-select the scene number for storing.

• Scene data is saved in the ACD1, not in each ampliﬁer.

• Stored scene data is valid only for the identical model of ampliﬁer. Scene data will be ignored if a different model of ampli-

ﬁer is connected with the same Amp ID.

• When you store a scene, the E symbol shown in screens that indicate the scene number will disappear.

Connector wiring

This section explains how to wire the [GPI] and [FAULT OUTPUT] connectors located on the ACD1’s rear panel.

Be sure to use the supplied Euroblock connector. If you lose the connector, contact your Yamaha dealer.

1. Loosen the terminal screws.

• Use a slotted screwdriver with a blade approximately 2 mm wide.

2. Insert the cables.

3. Securely tighten the terminal screws.

Pull the cables (not too strongly) to conﬁrm that they are securely connected.

4. Connect the Euroblock plug to the ACD1’s [GPI] connector / [FAULT OUTPUT] connector.

Euroblock plug connection

● Cable preparation

•To prepare the cable for attachment to a Euroblock connector, strip the wire as

shown in the illustration, and use stranded wire to make connections. With a

Euroblock connection, the stranded wire may be prone to breakage because of

metal fatigue due to the weight of the cable or due to vibration. When rack-mount-

ing your equipment, use a lacing bar when possible to bundle and fasten the cables.

• If cables will be frequently connected and disconnected, as in the case of a portable

installation, we recommend that you use ferrules with insulation sleeves. Use a fer-

rule whose conductor portion has an external diameter of 1.3 mm or less, and a

length of approximately 5 mm (such as the AI0,5-6WH made by the Phoenix Con-

tact corporation).

• If you use stranded wire, do not tin (plate with solder) the exposed end.

Connector wiring

Connect GPI (General Purpose Interface) devices (e.g., control-

lers) to the rear panel [GPI] connector.

You can use GPI to send or receive control signals to or from an

external device.

The ACD1 provides 4-port input and 4-port output.

• The +V terminals have an output voltage of 5 V. A maximum total of 100 mA of current can be drawn.

• The IN terminals detect voltage changes from 0 V to 5 V.

• The OUT terminals are open-collector outputs. A maximum voltage of +12 V can be applied.

•For each port, a maximum of 75 mA of current can ﬂow.

• Use Amp Editor to make settings such as parameter assignments.

•A Euroblock plug is used for connection to the [GPI] connector.

Euroblock connection methods are described in “Euroblock plug connection” (page 18) in this manual.

• By specifying the input/output channels in Amp Editor, you can recall scenes or edit parameters from a connected exter-

nal GPI device, or send signals to an external GPI device. For details on making settings, refer to the “Amp Editor owner’s

manual.”

•To adjust (calibrate) the range over which the input voltage to the [GPI] connector is detected, refer to “5. Utility” (page

13).

GPI connector

● Example : Controlling the ACD1 from a switch ● Example : Lighting the LED of an external device

from the ACD1

• Do not allow the current ﬂowing from the OUT

connector to exceed 75 mA.

● Example : Controlling the ACD1 via a 10k ohm lin-

ear taper potentiometer

Connector wiring

You can connect a lamp etc. to the rear panel [FAULT OUTPUT] connector to

indicate that an abnormality has occurred.

The [FAULT OUTPUT] connector consists of NO (Normally Open), C (Common), and

NC (Normally Closed). The [FAULT OUTPUT] connector is a relay circuit, and oper-

ates as follows.

The relay contacts used in the [FAULT OUTPUT] connector are rated for a load of 1A, DC 30V. Do not apply a load that

exceeds this rating.

Use Amp Editor to make settings for the [FAULT OUTPUT] connector.

Euroblock plugs are used for the [FAULT OUTPUT] connector. Euroblock connection methods are described in “Euroblock

plug connection” (page 18) in this manual.

• In Amp Editor’s [Device Setup] menu ➝ [Alert Setup], you can set Type to Fault so that a fault can be indicated by a con-

nected lamp, etc. For details on making settings, refer to the “Amp Editor owner’s manual.”

• The relay contacts are rated for a resistive load of 1A, DC 30V. Do not apply a load that exceeds this rating.
