Line Level Analog Inputs
4 balanced 24-bit, line-level, analog inputs are provided (1-2). 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. The line level inputs 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. See I/O Settings.
The maximum input level is 18dBV (=20.2dBu).
Either TRS balanced or TS unbalanced cables can be used. See page 84 for additional
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
 It’s also a good idea
to mute the Dock In strip
2L/2R 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.
The RCA turntable inputs feed an RIAA equalized preamp designed for moving magnet
type phono cartridges with 60 dB of gain. Connect the ground lead from your turntable
to the ground lug to prevent hum.
The turntable inputs share line level inputs 2L and 2R. Inserting a plug into Line Input 2
disconnects the turntable preamp from that channel. Do NOT leave your turntable
connected when using inputs 2L and 2R, since this can cause a ground loop.
Important: Do NOT plug in line level signals to the turntable inputs. The turntable
inputs are designed to accept the extremely low-level signal from a phonograph
cartridge. Use RCA to 1/4” adapters to connect line level signals to the line level analog
inputs.
Line Level Analog Outputs
 Balanced Cables:
You should ONLY use
balanced (TRS) cables if
BOTH pieces of
equipment use balanced
connections. Connecting
balanced cables between
balanced outputs and
unbalanced inputs can
actually increase noise
and introduce hum.
Six balanced 24-bit, line-level, analog outputs are provided (1-3). Output pair 1 is desig-
nated 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. 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. See I/O Settings.
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.
