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%.
