1) Mono Mic Out
Unbalanced mono mic-level output on
3.5 mm female connector, designed to
connect to wireless IFB transmitters or
transcription recorders. Tip = Hot (+),
Sleeve = Ground.
2) Tape Out
Unbalanced stereo output on 3.5 mm
female connector. Sleeve = Ground,
Tip = Left, Ring = Right.
3) RTN B In
Unbalanced stereo 3.5 mm female con-
nector for Return B audio input. Sleeve
= Ground, Tip = Left, Ring = Right. See
RTN B and RTN Loopback Mode.
4) 10-Pin Output Level Switch
Selects the Hirose 10-Pin Output level
between Line, -10, or Mic levels.
5) 10-Pin Master Outputs and Return A
10-pin connector includes second master
output (transformer-isolated from the
XLR outputs) and unbalanced stereo
Return A. Can be set to send out AES
digital signals. See AES Digit Outputs.
6) RTN B / TC Input
Unbalanced stereo input for Return B
audio and Time Code input on TA3 con-
nector. RTN B wiring pin 1 = Ground,
pin 2 = Left, pin 3 = Right. Time Code
wiring pin 1 and 3 = ground, pin 2 = Hot
(+). See Time Code.
7) TA3 Master Outputs
Line, -10, or Mic level selected in the
Setup Menu. Pin 1 = Ground, pin 2 =
Hot (+), pin 3 = Cold (-) float pin 3 to
unbalance.
8) Tape Output
Unbalanced tape-level stereo output
on TA3 connector. Pin 1 = Ground,
pin 2 = Left, pin 3 = Right.
9) Link I/O
Used to link additional Sound Devices
552, 302, 442, or MixPre mixers. See
Mixer Linking.
10) Headphone Outputs
1/4-inch and 3.5 mm stereo connectors,
drive headphones from 8-2000 ohm
impedances. 3.5 mm connection can be
set in the Setup Menu as an independent
boom operator send. See Talk Back Mode.

12) XLR Master Outputs
Transformer-balanced analog out-
puts on standard 3-pin XLR connec-
tors. Pin 1 = Ground; pin 2 = Hot (+);
pin 3 = Cold (-). Unbalance by tieing
pin 3 to pin 1. Can be set to send AES3
digital signals in the Setup Menu. See
AES Digit Outputs.
13) Battery Compartment
Holds four AA batteries required for
internal powering. Accepts Lithium,
Alkaline, and NiMH rechargeable cells.
14) DC Input
Accepts DC voltages from 10–18 V for
mixer powering. Pin 1 = Negative (–),
pin 4 = Positive (+). Ext DC is complete-
ly isolated (floating) from the rest of the
circuitry.
