    MT120’s mixer section has four “channels.” The term “track” refers to the magnetic bands on tape used to store signals recorded by MT120’s recorder section. Since MT120 records four separate bands of audio on tape, it is a four-“track” recorder.

  • Page 14: About Cassette Tapes

    ABOUT CASSETTE TAPES This unit is designed to be used only with Chromeposition tape, and will not work properly with Ferrichrome tape formulations. CrO2 tape (Bias: HIGH; EQ: 70µs) should be used. Also, the use tapes longer than 90 minutes (C-120, etc.) is not recommended because they exhibit poorer performance, and can be the cause of equipment failure.

  • Page 15: The Recording Process

    For details pertaining to the operation of MT120 controls, please refer to page 5, “MT120 CONTROLS AND THEIR FUNC- TIONS”. Recording with the MT120 is a very simple process. All you need is the MT120, a pair of monitor headphones, and an instrument, microphone, or other signal source.

  • Page 16: Recording The First Track

    Depending on what you are recording, you might want to record a single instrument or other source on a single track of the tape, or you might want to combine several instruments or other sources and record them on a single track. The MT120 offers two “channel-to-track assignment”...

  • Page 17: Step 2: Monitor Setup

    The MT120 allows you to monitor the material being recorded either via a pair of headphones connected to the PHONES jack or via a sound system with speakers connected to the MONITOR OUT jacks. The level appearing at the PHONES jack and MONITOR OUT jacks is controlled by the MONITOR/PHONES control.

  • Page 18: Step 3: Setting Recording Levels

    This is to ensure the best possible signal- to-noise ratio and allow plenty of plus and minus leeway 3. Press transport REC/PAUSE button, this activates MT120’s for later adjustment. If the fader setting is way off, try record circuit, and puts the transport in RECORD/PAUSE adjusting the volume control on the instrument or other mode.

  • Page 19: Overdubbing

    When MONITOR select is in the MONITOR position, it is not possible to hear input source unless MT120’s transport is in RECORD or RECORD/PAUSE. If you are not ready to actually record your overdub, and would like to hear the new input source along with previously recorded tracks, set the MONITOR select switch to the MIX position.

  • Page 22: Mixdown

    A “MIX” is created by finely balancing the four tracks to achieve just the right sound. This final balance is achieved using MT120’s mixer section and is re-recorded onto a conventional stereo tape deck. Tracks can be faded in or out as required, and refinements such as overall reverberation or equalization can be added using external signal processing equipment and MT120’s 5-band on-board GRAPHIC EQUALIZER.

  • Page 23: Using The Graphic Equalizer

    USING THE GRAPHIC EQUALIZER The MT120 has a stereo 5-band graphic equalizer built in. As the block diagram below makes clear, signals assigned to the left and right channels by the PAN control and level adjusted using the MASTER fader are sent to the equalizer. Therefore, it can be used during ping-pong recording, mixdown operation and when recording with the REC SELECT control set to “L”...

  • Page 24: Using The Tape Out Jacks

    USING THE TAPE OUT JACKS The tape out jacks can be used to feed the tape outputs to an external mixer. In mixdown, individual tracks can be processed using a signal processor, which receives signal from the TAPE OUT jack and the output of which is returned to a channel’s INPUT jack.

  • Page 25: Using The Aux Send/Return Loop

    USING THE AUX SEND/RETURN LOOP The MT120’s AUX SEND controls function like a secondary mixer that derives its input signals from the main mixer’s four channels and combines them into a mono signal which is delivered via the AUX SEND jack (refer to the diagram below). You can use the AUX SEND controls to create an “effect mix”, independent of the main mix, thus adding the required degree of...

    MAINTENANCE The MT120 recording & playback head has been precision-constructed to extremely fine tolerances in order to make high- quality 4-track recording possible. Optimum performance can only be achieved if the head surface is kept immaculately clean. Cleaning should be carried out at regular intervals — at least after every 10 hours of use Dirty heads can cause any of, or a combination of, the following problems: Recording, playback and erasure are not possible.
