Channel input jacks (Hi-Z, Lo-Z) 1~4
These are the input jacks for channels 1~4. By
using the PAD switches (control panel 5 ) you
can connect any of the jacks to a wide range of
sources from mics to line level devices (synthesiz-
ers or rhythm boxes etc.). The Lo-Z jacks can
provide +48 V phantom power, allowing you to
use condenser microphones.
Both Hi-Z and Lo-Z are balanced, and are com-
patible with microphones of output impedance
50~600 or line level devices of 600 . The nom-
inal input level is –40 dB~–10 dB for the Hi-Z
jacks, and –50 dB~–20 dB for the Lo-Z jacks.
Pin connections for the Hi-Z and Lo-Z jacks are
as follows.

(XLR type)
Pin 1: ground
Pin 2: hot (+)
Pin 3: cold (–)
+ -
GND
Note: It is not possible to simultaneously use
both the Hi-Z and Lo-Z inputs of a given chan-
nel. For each channel, use only one of the inputs
as appropriate for the input source.
Phantom power is switched on/off in simulta-
neously for channels 1~6. For this reason,
devices which do not require phantom power
must be connected to the Hi-Z or LINE jacks if
the PHANTOM +48 V switch (control panel
L) is on.

Channel input jacks (MIC/LINE) 5~6
These are the input jacks for channels 5~6.
Microphones can be connected to the MIC jacks,
and stereo line level devices (such as synthesizers
or rhythm boxes) can be connected to the LINE
jacks.
The MIC jacks are balanced, and are compatible
with microphones of output impedance
50~600 . The LINE jacks are unbalanced, and
are compatible with line level devices of 600
output impedance. Nominal input level is –50 dB
for the MIC jacks and –20 dB for the LINE jacks.
Note: It is possible to simultaneously use both
the MIC and LINE inputs for a given channel.
3
Effect output jack (EFFECT OUT)
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 k .
4
Foot switch jack (FOOT SW)
A separately sold Yamaha FC5 foot switch can be
connected to this jack. If a foot switch is con-
nected to this jack, you can use your foot to
switch the built-in digital effect on/off. The Digi-
tal Effect ON switch on the front panel must be
set to ON in order to use a foot switch.
5
External input jacks (AUX IN/TAPE IN)
These are input jacks that allow the signal from
an external device to be added to the MAIN out-
put. Monaural output devices such as external
effects can be connected to the AUX IN jack, and
stereo output devices such as cassette recorder or
CD players can be connected to the TAPE IN
jacks.
