EMX88S/EMX68S—Owner’s Manual
4EFFECT OUT jack
The input of an external effect such as a delay or
echo can be connected to this jack.
The signal adjusted by the EFFECT control of
each channel will be sent to the EFFECT bus, its
level adjusted by the EFFECT OUT control, and
output from this jack.
The nominal output level and impedance are
+4 dB/10 kΩ.
5FOOT SW jack
You can connect a Yamaha FC5 foot switch (sold
separately) to this jack and use it to turn the
built-in digital effect on and off. The Digital
Effect ON switch on the front panel must always
be set to ON in order to use the foot switch.
6AUX IN/2TR IN-INPUT TO MAIN jacks
These are input jacks that allow the signal from
an external device to be added to the MAIN out-
put.
•AUX IN jacks: Connect these jacks to the
output jacks of an external effects processor.
If the effects processor has a stereo output,
connect it to the AUX IN L (MONO) and R
jacks. If it has monaural output, use the AUX
IN L (MONO) jack. Signal input to these
jacks is sent to the stereo (MAIN L, R) bus.
•2TR IN jacks: Use these jacks to connect a
stereo device, such as a cassette player or a
CD player. The signals input to these jacks is
sent to the stereo (MAIN L, R) bus.
The nominal input level and impedance are –10 dB/
600Ω for the AUX IN jack, and –10 dBV/600Ω
for the 2TR IN jacks.
7REC OUT/MAIN (STEREO)/MONITOR-
OUTPUT jacks
These are output jacks which send line level sig-
nals from the EMX88S/EMX68S to external
devices. A stereo recording device such as a cas-
sette recorder or MD recorder can be connected
to the REC OUT jacks, and a playback device
such a power amp can be connected to the MON-
ITOR and MAIN (STEREO) jacks. The signals
sent from each jack are as follows.
•REC OUT jacks: The stereo (MAIN L, R)
bus signal before it has passed through the
MASTER control and graphic equalizer
•MONITOR jack: The MONITOR bus signal
which has passed through the MONITOR
MASTER control and graphic equalizer
•MAIN (STEREO) jack: The stereo (MAIN L,
R) bus signal which has passed through the
MAIN MASTER control and graphic equal-
izer
The nominal output level and impedance are
–10 dBV/10 kΩ for the REC OUT jacks, and
+4 dB/10 kΩ for the MONITOR/MAIN (STE-
REO) jacks.
