The terms “channel” and “track”: In this owner's manual, the term “channel” refers to the circuitry and

controls required to process one input source. MT120S's mixer section has four “channels.” The term
“track” refers to the magnetic bands on tape used to store signals recorded by MT120S's recorder section.

Since MT120S records four separate bands of audio on tape, it is a four-“track” recorder.



The INPUT SELECT switches are used to select the

input source for each of the four channels.


Select this position to play back already re­

corded material. When selected, mixer channel 1
will receive playback from track 1; channels 2, 3,
& 4 will receive tracks 2, 3, & 4 respectively.



In this position, the channel receives no input



In this position, the channel can receive a

microphone, keyboard, or other line-level signal

which is connected to the input jack.


All channels which are not in use should be set

to “OFF” position.



C/LINE Gain Controls

The gain controls adjust the sensitivity of the channel

inputs to accept a wide range of signal levels — from
line to microphone. The gain controls are used in con­

junction for the input faders to set the optimum record­

ing level with a wide range of sources (see “SETTING
RECORDING LEVELS” on page 15).


A gain control only affects the level of the signal

connected to the input jack.


^Input Faders

The input faders are used to adjust the level (volume)

of the corresponding mixer channel’s signal, whether it
comes from a source plugged into an input jack or from

the MT120S’s recorder section. (The INPUT SELECT

switches are used to choose between the two.) The

faders are used to set up the optimum levels when

recording, and to balance (mix) the sound from the
recorder’s tracks when playing back a recording.
Noise and distortion are at their lowest at input fader
level “7”.




The REC SELECT switches are used when recording
to assign (send) the signal from each mixer channel

either directly to the corresponding track of the re­

corder or to a different track via the PAN controls (see



When any of the REC SELECT switches are set

to a position other than OFF, the red indicator

LED of the transport REC/PAUSE button will flash,

indicating that the MT120S is set up to record.

Recording will commence when the PLAY button

is pressed after pressing the REC/PAUSE but­

ton. If all REC SELECT switches are set to OFF,
the unit will not record even if the REC/PAUSE

and PLAY buttons are pressed.


PAN Controls

The PAN controls assign the signal from the corre­

sponding mixer channel to any desired position in the
“stereo sound field”. If a PAN control is set to the

maximum “LEFT” position, the signal from that channel

will appear only at the left-channel MT120S output

(STEREO OUT L). If the PAN control is set fully RIGHT,

the signal will appear only at the STEREO OUT R

output jack. If a PAN control is set to its center posi­

tion, then the signal from that channel will appear equally

at both the left- and right-channel outputs, and the
sound will appear to come from the center of the stereo
sound field, a point midway between the two stereo
speakers. By varying the level of the signal sent to the

left-and right-channel outputs, the PAN control can be
used to position the sound at any point in the stereo

spectrum. The PAN controls can also be used during

recording to assign the signal from several channels to

a single track of the recorder section, or to assign a
channel to a differently-numbered recorder track (see
