Fig. 7.8: A and B-channel input section

A-channel line inputs
The A-channel line inputs accept balanced or unbalanced 1/4” jacks, tip = hot, 

ring = cold and sleeve = ground/screen.

Mic inputs
These are via XLR-type connectors, wired pin 1 = ground, pin 2 = hot and 

pin 3 = cold, for balanced low-level operation. Since most quality capacitor 

microphones require a 48 V DC offset to charge the plates, phantom power 

is provided and can be switched on or off in three blocks of eight via a switch 

situated below channels 8, 16 and 24.

Channel inserts
These provide for unbalanced send and return from a single stereo jack socket. 

Wiring is: tip = out, ring = in and sleeve = ground/screen.

Direct outputs
This tap comes from just after the channel fader. Unbalanced 1/4" jacks.

B-channel inputs/tape returns
They also accept balanced or unbalanced 1/4" jacks and are switchable, 

in groups of eight, between -10 dBV (unbalanced) and +4 dBu (balanced), 

corresponding to the standard semi-professional and professional operating 

levels and configurations respectively. Consult your multitrack manual to find out 

which one applies.

Subgroup outputs/tape sends
The eight subgroups are each connected to two stereo jack sockets, for easy 

patching into 16 track recording systems (or 24 track, if you use Y-adaptors). 

Once again, the operating level is switchable between +4 dBu and -10 dBV in two 

banks of (2x) 4.

You will need a lot of cables for a lot of purposes. Here’s how they should look:
