Hi-Z, Low-Z input jacks
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 Low-Z jacks can
provide +15 V phantom power, allowing you to
use condenser microphones.
Both Hi-Z and Low-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 Low-Z jacks.
Pin connections for the Hi-Z and Low-Z jacks are
as follows.

Note: It is not possible to simultaneously use
both the Hi-Z and Low-Z inputs of a given
channel. For each channel, use only one of the
inputs as appropriate for the input source.
Phantom power is switched on/off simulta-
neously for the Low-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 K) is on.

MIC, LINE, Super Hi-Z input jacks
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 1 & 2 jacks are unbalanced, and are
compatible with line level devices of 600 output
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.
Super Hi-Z 1 & 2 jacks are unbalanced, can be
used simultaneously, and their high input imped-
ance 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. Nomi-
nal input level is –30 dB.
Note: It is possible to simultaneously use both
the MIC and LINE inputs for channel 5, and the
MIC and Super Hi-Z inputs for channel 6.

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 (con-
trol panel 3) of each channel will be sent to the
EFFECT bus, and output from this jack.
The nominal output level and conforming
impedance are +4 dB/10 k .
