Precautions
User’s Guide
Precautions
1 Avoid excessive heat, humidity, dust, and vibration.
Keep the MT4X away from locations where it is likely to be
exposed to high temperatures or humidity, such as direct
sunlight, near radiators, stoves, etc. Also avoid locations which
are subject to excessive dust accumulation or vibration which
could cause mechanical damage.
2 Avoid physical shocks
Strong physical shocks can cause damage. Handle the unit with
care.
3 Clean with a soft dry cloth
Never use solvents such as benzine or thinner to clean the
MT4X. Wipe it clean with a soft dry cloth.
4 Do not open the case or attempt repairs or modification
yourself
The MT4X contains no user-serviceable parts. For other than
routine cleaning, refer all maintenance to qualified YAMAHA
service personnel. Opening the case and/or tampering with the
internal circuitry will void the warranty.
5 Make sure power is off before making or removing
connections
Always turn the power OFF prior to connecting or
disconnecting cables. This will prevent damage to the MT4X as
well as other connected equipment.
6 Handle cables carefully
Always plug and unplug cables — including the AC cord — by
gripping the connector, not the cord.
7 Always use the correct power supply
The MT4X is sold configured to the appropriate power
specifications for the local area. The power supply voltage and
power consumption are listed on the bottom panel. If you move
to an area with a different AC mains voltage, be sure to check
with your nearest YAMAHA dealer before using the unit.
8 Keep the heads and tape path clean
To ensure consistent high performance and sound quality from
the MT4X, it is important to clean the heads and tape path
regularly — ideally before each recording session. Use a
cleaning kit specifically designed to use with cassette tape
equipment.
9 Use only high-quality chrome cassette tape
The MT4X is designed to be used with Chrome tape (CrO
2
tape
— Bias: HIGH or TYPEII position; EQ: 70
µ
s). It will not work
properly with Ferrichrome tape formulations. You may
experience high frequency distortion if you use such tapes.
The use of tapes longer than 90 minutes (C-120 and longer) is
not recommended. These tapes are much thinner and therefore
prone to poor performance or failure.
TDK SA 46 – 90 and Maxell XLII 46 – 90 are recommended.
10 Handle the cassette tapes properly
You should fast forward and rewind new tapes before you
record on them. This will prevent any possible binding that
could be caused by the tape being tightly wound at the factory.
It is best not to use the first and last 20 seconds of a tape. The
splice between the leader and the tape can cause distortion.
When loading a cassette, check that the tape is not loose, then
load the tape firmly into the cassette compartment. If the tape is
not loaded properly, the unit may jam or otherwise malfunction.
11 Use the dbx™ switch correctly
To obtain the best possible sound quality, you should always use
the dbx™ noise reduction system to playback tapes that were
recorded with the dbx™ system on. If the tape was recorded
without dbx™, turn the noise reduction system off.
The dbx™ noise reduction system was manufactured based on a
patent licence from THAT Corporation. dbx is a trademark of
Carillion Electronics Corporation.

Introduction
Your MT4X Multitrack Cassette recorder is a powerful recording tool that will allow you to capture your
music at a very high level of sound quality. It is an advanced technology, easy-to-use four-track cassette
tape recorder with a comprehensive four-channel mixer.
In order to make use of the many features of the MT4X and to obtain the best performance, please read this
manual thoroughly — and keep it in a safe place for future reference.
Features
General
The MT4X consists of a four-channel mixer section and a four-track cassette tape recorder section inside a
compact enclosure. Independent recording and playback is possible for each track. This allows you to
create high-quality multi-track recordings.
Mixer
• The mixer section is equipped with independent stereo buses for greater flexibility.
• Continuously variable gain controls are provided for each input channel. These can be used with any
input source, from microphones to electronic instruments.
• Each channel has a three band equalizer (HIGH, MID, and LOW) giving you flexible tone-shaping
capabilities.
• Dual AUX SEND and AUX RETURN (stereo) connectors allow you to add effects from external signal
processors. You can assign the AUX RETURN signal to each channel as required.
Recorder
• The dbx
noise reduction system provides substantial noise reduction and a wide dynamic range.
• An automatic punch-in/out recording function and a rehearsal function make recording easier and
more accurate. Locate functions, such as memory and return-to-zero are provided for additional
convenience.
• A large, multi-functional display shows the recording and playback levels, along with a tape counter
and other indicators, giving you immediate and helpful information about the status of the MT4X.
• The pitch control allows you to vary the tape speed with in a range of approximately
±
10%. This can be
useful when you have to compensate for pitch variations during an overdub.
• The tape transport is a full-logic mechanism, making recording and playback operation smooth and
simple.
• The transport offers two speeds: 9.5 cm/sec and 4.8 cm/sec.

User’s Guide
Structure of the MT4X
The MT4X can be divided into three basic sections – the mixer, the recorder, and the bus lines which
connect them:
Mixer
The mixer has four input channels. It adjusts the input signals at each respective channel and sends them
to the bus lines.
The signals input to each channel of the mixer can be switched to either input signals (MIC/LINE) or
playback signals (TAPE). When TAPE is selected, the playback signal from each track is input to the
corresponding channel. The tone of the signal is adjusted through the equalizer and the volume at the
channel faders. It is then sent to the bus lines using the ASSIGN keys and PAN control.
Bus Lines
There are four main bus lines (group buses) which receive the input signals from each respective channel
of the mixer. If signals from two or more input channels are sent to a bus line, these signals are overlaid or
mixed.
There is also a STEREO bus (L, R), an AUX bus (1, 2), and a CUE bus.
Recorder
The signals from the bus lines are recorded by the cassette recorder. It also sends the signal to the
TAPE OUT connectors and back to the mixer (including the CUE bus).
Also refer to the "Block Diagram" on page 48.

3 Recording Functions
The basic functions of multitrack recording are as follows:
Monitoring
The MT4X offers you a great deal of flexibility in monitoring the status of your recordings. You can
monitor the individual channel groups, the stereo bus, the cue bus, or any combination.
Of these three monitor sources, you will probably find the cue bus is the most useful. This bus allows you
to monitor the previously recorded tracks as well as new material independently of the mixer section. It is
sometimes very important to be able to listen directly to the tracks, for example, to compare different
mixer settings to the original signal.
You adjust the overall monitoring level with the MONITOR/PHONES control.
Monitoring
Monitoring the recording or playback to listen for mistakes or
unwanted distortion.
Initial recording
Recording the first instrument or part.
Overdub recording
Recording additional instruments or parts while monitoring the
previously recorded tracks.
Punch-in/out recording
Correct mistakes or add short segments to an existing track.
Ping-pong recording
Bounce several existing tracks onto another track.
Mixdown
Mix the results of your multitrack recording onto a stereo master
tape.
You control monitoring with the MONITOR SELECT keys
0
:
GROUP
The GROUP keys allow you to monitor the group bus signals. If you only
press one key, you will hear monaural output. If you press both keys, you will
hear groups 1 and 3 in the left channel and groups 2 and 4 in the right channel.
The signals on the group buses go directly to the recorder.
STEREO
The STEREO key allows you to monitor the stereo bus signal. You can monitor
the signals from the four input channels as well as the AUX RETURN signal.
Some of these signals may not have been assigned to the group bus, allowing
you to listen to signals that will not be recorded.
CUE
The CUE key allows you to monitor the playback signals directly from the
cassette tracks. You can set the volume for each track with the CUE LEVEL
controls. The cue bus is monaural.
When you are recording, the record signal is monitored.

Initial recording
The first step in multitrack recording is to record the initial tracks. Usually, these are your rhythm tracks:
bassguitar, rhythm guitar, and drums.
Preparations for recording
1) Insert a cassette tape into the cassette tape compartment (
D
).
2) Connect the input source to the corresponding MIC/LINE INPUT connector for each channel.
3) Set the input select key (
6
) to the MIC/LINE position.
4) Rotate the GAIN control (
1
) to adjust the initial level of the input signal.
If you have plugged a microphone into the corresponding connector, rotate the control fully
clockwise to the MIC setting.
If you have plugged a synthesizer into the connector, or are running a bassguitar or guitar through a
signal processor (line level output), rotate the control fully counter-clockwise to the LINE setting.
Note:
Before you record anything, you must connect the MT4X to both an input source and a monitoring
system. See "Example System" on page 14.
Note:
This level setting is temporary — just to get a rough signal level based on the type of input you have
connected. Be aware that you could easily be sending a signal that is overloading the gain amplifier and
causing distortion. To set the final level, see steps 10 and 11.

5) Using the ASSIGN keys (
4
) and the PAN control (
5
) select the group bus you want the input
signal to go to.
If the PAN control is set to a position partway between L/ODD and R/EVEN, the input signal will
be sent to both the odd and even group buses.
If you press both ASSIGN keys, the input signal will be sent to at least two group buses.
6) Press the REC SELECT keys (
G
) for the tracks you want to record.
The corresponding REC SELECT - TRACK indicator (
c
) on the display will flash.
Press the REC SELECT key again to cancel the selection.
7) Press the MONITOR SELECT - CUE key (
0
). Adjust the CUE LEVEL controls (
A
) for the selected
tracks. Set the monitor volume with the MONITOR/PHONES level control (
B
).
8) Press the COUNTER RESET key (
Q
) to set the tape counter (
Y
) to “0000”.
Set the recording levels
In order to obtain the best possible sound quality, it is very important to set optimal recording levels. If
you set the levels too low, you will be able to notice tape noise. If you set the levels too high, the tape will
be saturated and distortion will result. Therefore, you should set the recording levels to the highest level
before distortion sets in.
The MT4X is equipped with sensitive peak-hold level meters (
Z
). You can monitor the level of the
individual tracks and the stereo bus. Use the level meters in conjunction with the monitoring modes (see
"Monitoring" on page 15) to set your recording levels.
Press the
ASSIGN key:
and rotate the
PAN control:
The input signal is sent to the first (odd) group.
Press the
ASSIGN key:
and rotate the
PAN control:
The input signal is sent to the second (even)
group.
Press the
ASSIGN key:
and rotate the
PAN control:
The input signal is sent to the third (odd)
group.
Press the
ASSIGN key:
and rotate the

9) Press the REC/PAUSE key (
S
).
The indicator above the key lights and any flashing REC SELECT - TRACK indicators will be
illuminated.
10) Set the channel fader (
7
) to the nominal level between “7” and “8”.
11) Adjust the GAIN control while watching the level meters.
• When dbx™ is off, adjust the gain control so that the +3 dB segment occasionally illuminates.
• When dbx™ is on, adjust the gain control so that the +9 dB segment occasionally illuminates.
Record the track
12) Press the PLAY key (
T
).
The indicator above the key lights and the MT4X starts the tape. Start playing.
13) When the track is complete, press the RETURN TO ZERO key (
I
) to stop and rewind the tape.
The indicators above the REC/PAUSE and PLAY keys switch off and the REC SELECT - TRACK
indicators resume flashing.
Check the completed recording
Once the tape has rewound back to “0000” on the tape counter, you should check the recording.
14) Press the PLAY key to playback the tape.
15) If the recording needs to be redone, repeat the previous steps.
• If the problem with the recording was a musical error, press the REC/PAUSE key and repeat
steps 12 to 14.
• If the problem was due to incorrect recording levels or other engineering problems, adjust the
parameters by repeating steps 4 to 14.
16) When you are finished with an instrument, you should set the channel fader to “0”. You may even
want to disconnect the input source.
Note:
The meters display a range of -20 dB to +9 dB. If the meters exceed the normal limit momentarily, this is
usually perfectly acceptable. Cassette tape is reasonably forgiving of transients – and human hearing has difficulty
detecting the minor distortion that results. Where you start getting audible problems is when the meters are
constantly above the normal limit. You must lower the levels in order to maintain decent sound quality.
Note:
The MT4X can recall and display the maximum recording levels obtained during a session. See
"Recording Levels Function" on page 42.
Tip:
If your song starts with drums, bassguitar, and guitars all on the first bar, you will need to record a
count-in.
Tip:
You may want to use the STOP key (
W
) to stop the tape and mark a memory point. See "Memory
Functions" on page 41.
