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.

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.

3 Press the [STOP] button to stop recording.

The Track 1 REC SELECT indicator ﬂashes.

Listening to the ﬁrst track

4

Press the [REW] button to rewind the tape.

If the [ZERO STOP] switch is set to ON, the tape

rewinds until the tape counter shows “000” and stops

automatically.

5 Press the [PLAY] button to start playback.

If the [INPUT-FLIP] switch on Input Channel 1 is set

to “MIC/LINE ( )”, you can monitor the Track 1

playback sound (sent via the CUE bus) through the

PHONES or MONITOR OUT jack.

To record again, rewind the tape to the beginning and

press the button. If you wish to re-record part

of the recording, perform punch in/out recording. See

page 34 for more information.
