Welcome to the MT400
MT400 Features
The MT400 consists of three major sections: a Mixer section that enables you to mix sounds
(with eight inputs and one stereo output): a Recorder section that records and plays sound
(with four tracks and four channels): and utility sections including meters, power switch, etc.
Mixer
• Continuously variable GAIN controls on Input Channels 1 through 4 allow the MT400 to
handle any type of input source with ease, including microphone and line-level signals such as
synthesizers.
• Musical three-band EQ on each input channel, and INSERT I/O jacks on Input Channels 1
and 2 for external processor patching enable high-quality recording.
• Two auxiliary sends for external reverb and other effects processor patching.
• Two stereo input jacks for connecting a synthesizer and other line-level instruments that have
stereo outputs. These jacks can be also used to return processed signals from external signal
processors.
• In-line configuration that allows you to control input signals and tape playback signals
simultaneously. You can monitor track signals adjusted by the CUE controls, while making a
recording on all four input channels. During mixdown, you can play back four-track signals
via the input channels, while mixing input signals via the CUE controls.
Recorder
• dbx™ noise reduction system provides a signal-to-noise ratio in excess of 80 dB.
• Punch in/out functions using a footswitch or the switch on the panel.
• SYNC OUT outputs a sync track (Track 4) signal, providing synchronous operation between
the MT400 and a MIDI sequencer. In SYNC mode, the dbx noise reduction can be turned off
for Track 4, ensuring reliable synchronization.
• Tape speed is switchable between 9.5 cm/second and 4.8 cm/second. The MT400 standard
tape speed is 9.5 cm/second for greater sonic performance. A speed of 4.8 cm/second is the
same speed as a normal cassette recorder, doubling the recording time relative to the MT400
standard speed. Pitch control enables you to fine-adjust the pitch in the range between –10%
and +10%.

—Owner’s Manual
Buying Cassette Tapes for the MT400
It is important that you buy the correct type of cassette tape for use with your MT400. You
should buy high-quality Type II (High Bias, 70
µ
s EQ) chrome cassettes of 90 minutes or less,
such as TDK SA or MAXELL CDXL II.
At normal speed, a 60-minute cassette provides about 15 minutes of recording time. That is
because the tape runs at twice the speed of a normal cassette recorder and you can use only
one side of the tape.
The following table shows the available recording times with three standard tape sizes:
MT400 Recording Format
A normal cassette recorder uses only two tracks (i.e., left and right stereo channels) for each
side (A and B). The transport direction of the A side is opposite that of the B side. The MT400
uses only one side of the cassette, and records and plays up to four tracks simultaneously or
one at a time. Therefore, tapes with all four tracks recorded on the MT400 cannot be played
on normal cassette players. If you try to play back a tape recorded with normal cassette
recorders on the MT400, you will hear Tracks 3 and 4 play backwards.
Normal cassette recorder tracks
MT400 tracks
The tape speed of normal cassette recorders is 4.8 cm/second. On the other hand, the MT400
uses 9.5 cm/second as its standard speed to achieve high-quality sound.
Cassette Tape
MT400 Recording Time
(with the standard speed)
C90 Approx. 22.5 minutes
C60 Approx. 15 minutes
C46 Approx. 11.5 minutes
Note:
We recommend that you use a brand new cassette tape for important recording. If you
record on a used tape repeatedly, the recorded sound may skip or sound quality may
deteriorate.

About dbx Noise Reduction
The MT400 uses the dbx noise reduction system to reduce tape hiss and keep your recordings
clean and crisp. For the best performance, it is recommended that you use the dbx noise
reduction for all your recordings. You should always use the dbx noise reduction system to
correctly play back tapes that were recorded with the dbx system on.
Glossary
This section describes basic terminology used in this manual.
■
Input channel
A path (channel) for audio signal between a mixer input jack and the bus (see below). Signal
input at an input jack is adjusted for the volume level and tonal quality here before being sent
to the bus.
■
Track
The MT400 can record four individual sound sources simultaneously on the four sections of a
cassette tape. This does not mean that the tape is cut into four pieces. The tape forms four
magnetic bands along the length of the tape. Each magnetic recording band is called a “track”.
The MT400 can use up to four tracks (Tracks 1–4).
■
Bus
A path where multiple audio signals are mixed into one signal. The MT400 offers the
following buses that can be used depending on the purpose.
Stereo L/R bus
— This bus is used to create a stereo signal. Stereo bus signal is output
from the STEREO OUT L/R jacks. You can record stereo L bus signal to both Track 1
and 3 of the recorder section, and stereo R bus signal to both Track 2 and 4. To monitor
stereo bus signals, use the MONITOR OUT L/R jacks. You can also monitor them via
headphones.
Cue bus
— This bus is used to create a monaural signal for monitoring, which is
output from the MONITOR OUT L/R jacks. You can also monitor the signal via
headphones.
AUX 1 and 2 buses
— These buses are used to send out signals to connected effects
processors from the AUX SEND 1 and 2 jacks in monaural. You can monitor the signals
via headphones.
■
Overdubbing
Overdubbing is a technique used to record new sounds to empty tracks while listening to the
sounds already recorded on other tracks.
■
Ping-pong recording
Ping-pong recording is a technique used to free up tracks by mixing one or two existing tracks
to an unused track.
■
Mixdown
Mixdown is a technique used to mix the sounds into a balanced stereo mix and record it to a
stereo master recorder. It is also called “tracking down”.

Touring the MT400
This section takes you on a tour of the MT400, identifying the various parts to familiarize you
with your new recorder.
Input Channels
A
GAIN control
This rotary control adjusts the sensitivity of the MIC/LINE
INPUT jack
d
so that both microphone and line-level (such
as a synthesizer) signals can be handled with ease.
B
EQ control
These rotary controls are used to adjust a tonal quality of the
high, middle, and low frequency bands independently. They
boost (amplify) and cut (attenuate) the corresponding basic
frequency in the range of
±
12 dB. A flat setting (i.e., no boost
or cut) can be set quickly using the control’s center detentes.
HIGH: Basic frequency 12 kHz (shelving type)
MID: Basic frequency 1 kHz (peaking type)
LOW: Basic frequency 80 Hz (shelving type)
C
AUX controls
These rotary controls are used to send the input channel (1–4) signal to the AUX SEND 1 and
2 outputs. They are commonly used to adjust the level of signal sent to external effects
processors.
D
CUE control
This control is used to adjust the level of Track (1–4) input signal and playback signal that will
be sent to the cue bus. The CUE bus signals are output from the PHONES jack or the
MONITOR OUT jack for monitoring.The CUE signal source depends on the [INPUT-FLIP]
switch
5
.
Note:
The AUX controls handle post-fader signals (signals that have passed through the
faders
7
). If the faders are lowered all the way, the AUX control settings will not be effective.

INPUT-FLIP switch
This switch is used to select the destination of the signal input from the MIC/LINE INPUT
jacks and the tape signal. With the switch in the MIC/LINE position ( ), the MIC/LINE
input signal is fed to the ST bus via the input channel and the tape signal is fed to the CUE
bus.
With the switch in the TAPE position ( ), the MIC/LINE input 1, 3 (2, 4) signal is fed to the
ST L (ST R) bus and the tape signal is fed to the ST bus via the input channel.
F
PAN control
This rotary control is used to adjust the stereo position (left or right) of input channel signal
that will be sent to the Stereo bus. For recording via the Stereo bus (See page 22), turn this
control all the way to the left to assign the signal to odd tracks (1, 3), and all the way to the
right to assign the signal to even tracks (2, 4). For mixdown you can use it to pan the playback
signal in the stereo mix.
G
Fader
For recording ([INPUT-FLIP] switch: MIC/LINE), use the fader to adjust the level of the
input channel signal that is recorded to a track. For mixdown ([INPUT-FLIP] switch: TAPE),
use it to adjust the playback level of each track. Unity gain is obtained when the fader is
positioned about the 7–8 mark.
Unity gain
: The condition where the output signal and input signal are at the same level,
with signal-to-noise ratio and distortion set to optimum.

Turning On the MT400
1. Make sure that the plug of the supplied AC
adapter is securely connected to the DC12V
jack on the rear of the MT400.
2. Plug the other end of the AC adapter into a
suitable AC outlet.
3. Press the POWER switch on the rear panel of
the MT400. The POWER indicator in the
meter section lights up.
Loading a Cassette Tape
Before loading a cassette tape, make sure the tape is
not slack inside the cassette. Also, make sure the write-
protect tabs are not broken. If they are broken, you
cannot record on the tape.
1. Open the cassette compartment cover.
2. Load the cassette into the compartment with
the A side facing up.
3. Close the cassette compartment cover.
If it is a new tape, fast forward and rewind it once to
prevent binding, which may occur due to the tape
being tightly wound during manufacturing.
4. Press the [PLAY] button to start playback, and
stop after about 20 seconds.
It is best not to use the first and last 20 seconds of a
tape, as the splice between the leader and tape can
cause distortion.
Recording the First Track
The MT400 allows signals input at MIC/LINE INPUT 1–4 to be directly recorded on Tracks
1–4 respectively (this is called “direct recording”). Connecting a sound source to MIC/LINE
INPUT 1 will automatically select Track 1 for recording, and connecting another sound
source to MIC/LINE INPUT 3 will automatically select Track 3 for recording. This is
convenient for recording one sound source at a time.
This section explains how to record the first sound source in Track 1.

Selecting a recording track
1
Connect a sound source to MIC/LINE INPUT
1.
It is best to record a rhythm instrument, such as a
rhythm machine, drums, or a rhythm guitar, first.
2 Set the [INPUT-FLIP] switch on Input Channel
1 to “MIC/LINE ( )”.
This switch setting sends the MIC/LINE INPUT signal
to the corresponding input channel.
3 Set Track 1 [REC SELECT] switch to “ ”.
The [REC SELECT] switches enable you to select a
recording source for each track. With Track 1 [REC
SELECT] switch set to “ ”, Track 1 is ready for
recording, and the signal on Input Channel 1 is sent to
Track 1. Also, the Track 1 REC SELECT indicator
flashes.
Checking the recording level
It is essential to set an appropriate recording level to
achieve the best sound quality. Be sure to adjust the
recording level before each recording session.
4 Set the [METER SELECT] switch to “ ”.
The [METER SELECT] switch is used to select a signal
monitored on the level meters. With the “ ”
setting, you can monitor the input level of the
recording source on the recording/recording-pause
tracks, and the tape signal level on the playback tracks.
5 Press the [PAUSE] button.
6 Press the button.
The Track 1 REC SELECT indicator stops flashing and
lights up continuously, and the MT400 enters
recording pause mode. Since you pressed the [PAUSE]
button, recording does not start.
7 Turn the GAIN control on Input Channel 1 all
the way to LINE.
8 Raise the fader on Input Channel 1 up to
between marks 7 and 8.
9 Play the sound source, and turn the GAIN
control while checking the level meter to
adjust the recording level. Set the [dbx]
switch and the [ZERO STOP] switch to “ON”.
Adjust the GAIN control so that the +3 segment of the
level meter lights up momentarily on the loudest
sounds if dbx has been turned off, and the +6 segment
of the level meter lights up momentarily if dbx has
been turned on.
If the recording level is very high even when the GAIN
control is turned all the way to LINE, lower the output
level on the sound source.
Monitoring a track recording signal
0
Set the monitor select switch to “CUE”.
The monitor select switch enables you to select a
monitoring source. The “CUE” setting sends the CUE
bus signal (monaural) to the connected audio system
or headphones for monitoring via the PHONES and
MONITOR OUT jacks.
A Set the CUE control on Input Channel 1
midway around noon.
The CUE controls on Input Channels 1–4 adjust the
level of the signals (recording source signals on the
recording/recording-pause tracks, and tape signals on
the playback tracks) that are sent from Tracks 1–4 to
the CUE bus.
B While monitoring the signal through the
headphones or the audio system, use the
MONITOR LEVEL control to adjust the
monitoring sound to the desired level.
C If necessary, use the EQ controls to adjust
tonal quality.
Adjusting the EQ controls will change the recording
level as well. After you adjust the EQ controls, adjust
the GAIN control for the recording level again, if
necessary.
