• EFFECT
This is an impedance balanced phone type output jack with a nominal output/impedance of +4dB/
600Ω.
The EFFECT bus signal is sent from this jack. This jack is used to send the signal to an external
effector, etc.
rRETURN L (MONO), R Jacks
These are unbalanced phone type line input jacks with a nominal input/impedance of +4dB/600Ω.
The signal received by these jacks is sent to the STEREO bus, AUX1 and AUX2 buses.
These jacks are normally used to receive a return signal from an external effector such as reverb, delay,
etc., but they can also be used as an auxiliary stereo input. If only the L (MONO) jack is used, the same
signal will be sent to both the R and L jacks for monaural input.
tGROUP OUT (1-4) Jacks
These are impedance balanced phone type output jacks that deliver the GROUP bus 1-4 signals, with a
nominal output/impedance of +4dB/600Ω.
These jacks are normally connected to the input jacks on an MTR or external mixer.
yTAPE IN (L, R) Jacks
These are line input jacks for monitoring an external DAT recorder or CD player. The signal received by
these jacks is sent to the STEREO bus. In this case, the TAPE IN control is used to adjust the input level
of the signal. You can also monitor directly from the C-R/ PHONES jack by making the appropriate
selection with the C-R/PHONES Output and Meter Select Switch (Master Control Section).
uREC OUT (L, R) Jacks
With an external DAT recorder or cassette recorder connected to these jacks, you can record the same
signal that is sent from the ST OUT jacks.
The signal sent from these jacks is not affected by the ST Master Fader or Graphic EQ settings. Make
recording level adjustments on the recording device.
iPOWER Switch
When the switch is in the ON position, the unit is powered.
When turning the power ON, first turn on the mixing console, then turn on the power amp or powered
speakers that are connected to the mixer.
Also, when turning the power OFF, turn off the power amp or powered speakers before turning off the
mixing console.
