How to use ''channel patching" accessory jack
The accessory jack (Tip, Ring, Sleeve) is provided on each input channel to allow insertion of
outboard signal processing devices (example: compressor/limiters, noise gate, equalizer, etc.)
into the signal path. The jack functions as both an output and an input (Tip=Receive,
Ring=Send, Sleeve=Shield). Connection cables for this purpose should be wired as illustrated
in
Fig.
2.
Inserting a plug into the jack interrupts normal signal flow and places the external device into
the circuitry just prior to the input equalizer section. (See Fig. 1.)
*The connection marked of the shield
and sleeve is determined by the type of
equipment to be connected.

The accessory jacks may also be used as a direct output for each input channel, allowing direct
connection to a multi-track tape deck or use as an additional effects mix.
To unbalanced input of
other input channels to
mix dry signals with
processed signals.

Normal impedance of the accessory send is greater than 10k ohms and the receive impedance
is 10k ohms. Both nominal levels are at 0dB (0.775V).
