Here’s the basic procedure for setting up an input channel to which a microphone or instrument
is connected via [MIC/LINE INPUT] jack 1–8, and adjusting the input level while monitoring the
signal via the stereo bus.
1
Turn down the [GAIN] knob for the [MIC/
LINE INPUT] jack to which your instrument/
mic is connected. Also lower the [STEREO]
fader to the – ∞ position.
2
Connect a microphone or instrument to the
appropriate [MIC/LINE INPUT] jack.
[MIC/LINE INPUT] jacks 1–8 can be used with the
following sources.
● [MIC/LINE INPUT (XLR)] jacks 1–8
These are XLR-type balanced input jacks. Use a male
XLR ↔ female XLR cable to connect your micro-
phone, direct box, or a guitar/bass preamp that has a
balanced output jack.
● [MIC/LINE INPUT (TRS phone)] jacks 1–8
These are TRS-type balanced input jacks. Use a 1/4"
TRS phone ↔ female XLR cable to connect your
microphone, direct box, or a guitar/bass preamp that
has a balanced output jack.
These connectors will also accept unbalanced output
from instruments such as synthesizers or rhythm
machines via standard mono 1/4" phone ↔ 1/4" phone
jack cables.

While playing the connected
instrument or supplying
appropriate sound to the
connected microphone,
rotate the corresponding
[GAIN] knob clockwise to
adjust the input sensitivity
so that the [PEAK] indicator
lights only occasionally.

• When using condenser microphones or direct boxes that
require phantom power, turn on the rear-panel [CH1-4] switch
which supplies phantom power to [MIC/LINE INPUT] jacks 1–
4, and/or the [CH5-8] switch which supplies phantom power to
[MIC/LINE INPUT] jacks 5–8 as required.

• The XLR and TRS phone jacks for the same channel cannot
be used simultaneously. Connecting sources to both inputs
on the same channel at the same time can result in interfer-
ence and a severely degraded input signal.
NOTE
• The [GAIN] knobs adjust the gain (sensitivity) of the analog
input stage. In order to make recordings with the greatest
dynamic range and minimum noise, set the [GAIN] knob as
high as possible without causing clipping.
