4. STEREO OUT ANALOG (1 and 2) connectors
STEREO OUT (1) are balanced XLR-3-32 type connectors with a
+4 dB nominal output level. STEREO OUT (2) are unbalanced
RCA/phono jacks with a –10 dBV nominal output level.
These connectors output the main stereo signals for recording, and
can be connected to cassette and other analog recorders.
5. 2TR IN ANALOG (1 and 2) connectors
2TR IN (1) are balanced phone jacks with a +4 dB nominal input
level. 2TR IN (2) are unbalanced RCA/phono jacks with a –10 dBV
nominal input level.
Signals input here are fed through to the CONTROL ROOM
buttons (24) and are monitored in the control room or the studio.
The outputs of a 2-track master recorder can be connected here for
confidence monitoring and playback.
6. Stereo input channels (17 to 24)
These are pairs of balanced 1/4" phone jacks with a –40 to +4 dB
nominal input level. You can connect the return from a stereo
effects unit (for example the YAMAHA D5000 digital delay) to
these input channels.
The signals from 2TR IN DIGITAL (1) can be routed to channels
17/18 and the signals from2TR IN DIGITAL (2) can be routed to
channels 19/20.
7. Input channels (9 to 16)
These are balanced phone jack connectors. The nominal input level
is –60 dB to +4 dB. Wiring is sleeve–ground, tip–hot (+), and
ring–cold (–). They can be used with balanced or unbalanced
plugs.
8. Input channels (1 to 8)
INPUT A (1 to 8) are balanced XLR-3-31 type connectors. The
nominal input level is –60 dB to +4 dB. They are wired according to
the IEC 268 standard: Pin 1–ground, pin 2–hot (+), and pin 3–cold
(–). Phantom powering is available for condenser type
microphones.
Note: Make sure that the balanced devices you plug into the input
connectors also use pin 2–hot, pin 3–cold wiring. If they are wired
differently, undesirable phase shifts may occur. However, you can invert
the phase of an input signal with the 02R.
INPUT B (1 to 8) are balanced phone jack connectors. The nominal
input level is –60 dB to +4 dB. Wiring is sleeve–ground, tip–hot (+),
and ring–cold (–). They can be used with balanced or unbalanced
plugs. See the note above.
INSERT I/O (1 to 8) are unbalanced phone jack connectors. Both
the nominal output and input levels are +0 dB. Wiring is
sleeve–ground, tip–out, and ring–in. Connect external dynamic
processors and other analog devices here.
