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.

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.
