Channel input jacks (MIC, LINE) 1~8
These are the input jacks for channels 1~8.
By using the GAIN control (control panel
1
)
you can connect any of the jacks to a wide range
of sources, from mics to line-level devices
(including synthesizers and rhythm machines).
The MIC jacks can p48V phantom
power, allowing you to use condenser micro-
phones.
Both MIC and LINE are balanced.
They are compatible with microphones of output
impedance 50~600
Ω
or line level devices of
600
Ω
. The nominal input level is –34 dB~+10 dB
for the LINE jacks, and –60 dB~–16 dB for the
MIC jacks.
Pin connections for the MIC and LINE jacks are
as follows:
* You can also connect a normal unbalanced phone plug.

INSERT I/O (insert) jacks 1~4
These are TRS phone jacks that enable you to
insert an external effect processor, such as a com-
pressor/limiter, between the equalizer and fader
of input channels 1~4. These connections require
a special “Y” cable, such as shown in the follow-
ing diagram. The nominal input/output levels are
0 dB.

Note: It is not possible to simultaneously use
both the MIC and LINE inputs of a given chan-
nel. For each channel, use only one of the in-
puts as appropriate for the input source.
Phantom power is switched on/off simulta-
neously for channels 1~8. For this reason, de-
vices (in particular, unbalanced devices) other
than condenser microphones must be connect-
ed to the LINE input jacks of channels 1~8 or
channel 9/10~11/12 input jacks if the PHAN-
TOM +48V switch (control panel
Y
) is on.
