Line Level Analog Inputs

Six balanced 24-bit, line-level, analog inputs are provided (1-3). These can be used to
input any line level signal from keyboards, CD-players, cassette decks, etc. The analog
inputs are assigned to mixer strips in the mixer application. Input line level can be set to
accommodate the consumer -10dBV standard, or the pro audio +4 dBu standard in the
I/O screen of the Session Settings dialog box.
The maximum input level in pro mode is 18dBV (=20.2dBu). Maximum output level in
consumer mode is 6dBV.
Either TRS balanced or TS unbalanced cables can be used. See
information about unbalanced cables and connectors. The line-level inputs are all
servo-balanced, enabling them to convert unbalanced signals to balanced signals
internally to reduce noise.
Turntable Inputs & Ground Lug
The RCA turntable inputs feed an RIAA equalized preamp designed to accept moving
magnet type phono cartridges. The turntable inputs share line level inputs 3L and 3R.
Inserting a plug into Line Input 3 disconnects the turntable preamp from that channel.
Connect the ground lead from your turntable to the ground lug to prevent hum.

Line Level Analog Outputs

Eight balanced 24-bit, line-level, analog outputs are provided (1-4). Output pair 4 is
designated as the Monitor Output and is fed by the monitor bus of the PatchMix DSP
mixer application. We suggest that you plug your speakers in here. All the analog
outputs can be freely assigned in the mixer application. Special anti-pop circuitry mutes
the analog outputs when power is turned on or off.
Like the analog line inputs, either TRS balanced or TS unbalanced cables can be used.
Balanced cables provide better noise immunity and +6dB higher signal level. The output
line level can be set to accommodate the consumer -10dBV standard, or the pro audio
+4 dBu standard in the I/O screen of the Session Settings dialog box.
The maximum input and output line levels are matched when the input and output
settings are set to the same mode (pro or consumer) in the I/O preferences screen.
IMPORTANT NOTE:
Do NOT use balanced audio cables (TRS) when connecting balanced outputs to
unbalanced inputs. Doing so can increase noise levels and introduce hum.

for additional
leave your turntable
connected when using
outputs 3L and 3R. This
can cause a ground loop.
• It' s also a good idea to
mute Dock inputs 3 in the
PatchMix DSP mixer
when nothing is plugged
in, since the turntable
preamp has a very high
gain (60dB) and could
contribute extra noise to
your mix/monitor bus.
See I/O Settings.
