Yamaha MT120S - Manual (Page 7)

MT120S CONTROLS AND THEIR FUNCTIONS
[Note] 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.
O INPUT SELECT Switches
The INPUT SELECT switches are used to select the
input source for each of the four channels.
TAPE: 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.
» OFF: In this position, the channel receives no input
signal.
MIC/LINE: In this position, the channel can receive a
microphone, keyboard, or other line-level signal
which is connected to the input jack.
[Note] All channels which are not in use should be set
to “OFF” position.
O mi 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).
[Note] A gain control only affects the level of the signal
connected to the input jack.
H
^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”.
OREC select Switches
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
“CHANNEL-TO-TRACK ASSIGNMENT” on page 13).
[Note] 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
“CHANNEL-TO-TRACK ASSIGNMENT” on page 13).
