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 +15 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

. 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.

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

impedance. These two input jacks can be used 
simultaneously.
Nominal input level is –50 dB for the MIC jacks 
and –10 dB for the LINE jacks.

INST 1 & 2 jacks are unbalanced, can be used 
simultaneously, and their high input impedance 
makes them ideal for use with instruments such 
as electric-acoustic guitar and electric bass. They 
can also be used with line-level sources, such as 
synthesizers and drum machines. Nominal input 
level is –30 dB.

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, and 
output from this jack.

The nominal output level and impedance are 
+4 dB/10 k

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.

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 the Lo-Z jacks of channels 1–4 and 
the MIC jacks of channels 5–6. For this reason, 
any devices other than condenser microphones 
must be connected to the Hi-Z or LINE jacks if 
the PHANTOM switch (control panel L) is on.

MIC and INST inputs for channel 6.
