@ POWER SWITCH
Turn ON to apply power to the unit. The VU meters light
when power is turned on.
@ INPUT (MIC/LINE)
Balanced connectors for line or microphone input. Rated
input level is —60 to —20dB, microphone impedance is 50 to
250 ohms, and line impedance is 600 ohms.
Ө TAPE IN —10dB _
Pin jack connectors for input of up to eight channels from a
tape deck or several tape decks. Rated input level is —10dB;
optimum input impedance is 600 ohms.
© DIRECT OUT —10dB
Directly outputs the signal from each input channel before
mixing. Unbalanced pin jack output terminals. These outputs
can be used with a 4 or 8 channel deck for real-time record-
ing or after recording. Rated output level is -Тоав, optimum
impedance is 10K ohms.
© INSERT IN/OUT -10dB
Unbalanced inputs and outputs that permit inserting external i
signal processing equipment between the equalizer and fader
stage of each input channel. Unplug the jumper cables only
when inserting external equipment.
Rated level/optimum impedance:
IN —10dB/600 ohms
OUT —10dB/10K ohms.
SUBIN —10dB
Unbalanced input for addition of a submixer in order to
expand the number of available input channels. Unbalanced
pin jacks with a rated input level of —10dB. Optimum
impedance is 600 ohms. |

TAPE: 1098
@ РСМ OUT —10dB
Unbalanced output terminals for connection to а multitrack
tape deck. Pin plugs with a rated output level of —10dB.
Optimum impedance is 10K ohms.
Q ECHO SEND —10dB
Outputs the echo mix to an external echo or reverb unit,
Also may be used as a cue mix for a headphone amp. Level is
determined by the input channel ECHO controls and the
master ECHO SEND control. Standard 1/4" phone plug with
a rated output: level of —10dB. Optimum impedance is
10K ohms. |
О ECHO RETURN —20dB
Unbalanced inputs for return of the output signal from an
external echo or reverb unit. A source plugged into the L
terminal only is treated as a mono source and is sent to the
L and R return busses. Standard 1/4" phone plug with a
rated input level of —10dB. Optimum impedance is 600
ohms. Also may be used for additional 2-track tape input.
@ MONITOR. OUT +4dB
Unbalanced monitor buss output. Standard 1/4" phone plug
with a rated output level of -4dB. Optimum impedance is
10K ohms.
Ф STOUT -10dB
Outputs the stereo buss mix as determined by the input
channel STEREO mix controls at the overall level determin-
ed by the STEREO master fader. Can be used as outputs to a
2-track recorder. Pin jacks with a rated output level of
—10dB, Optimum impedance is 10K ohms.
Ф 2TRKIN —10dB -
-Unbalanced input terminals for connection to the outputs of
a 2-track tape deck. Pin jacks with a rated input level of
—10dB. Optimum impedance is 600 ohms.
