V. AUX 1/2 Source mod

This modification should only be performed if

the console is being used strictly for recording.
A
. When the Aux 1/2 Pre Switch is engaged,

Aux Send 1 and 2 will tap the Pre-Fader
information from the tape returns.

B. When the Aux 1/2 Pre Switch is not engaged,

Aux Send 1 and 2 function normally, as post
fader channel sends.

.

All that said, here’s the mod.

See Figure 13 (appropriately numbered)
above. This modification takes place on each
channel strip in the area under the AUX 3/4
Mix-V Source switch and also under and near
the AUX 1/2 PRE switch.

1. Remove power cord.

2. Cut two (2) traces at point (A).

Note: The wire used in the next three steps
should be 24-28 gauge insulated jumper wire.
Do not strip off any more insulation than is
absolutely necessary.

3. Add a 1-1/2” jumper (B), connected at

points K and L.

4. Add a 2-1/4” jumper (D), connected at

points P and Q.

A note about adding jumpers during

these modifications

When a jumper or jumpers are called for, they

should NOT go into holes in the PCB. Rather,
they should be soldered to the flat, tinned area
around the hole (called a pad) and bowed
slightly over to the other pad (see right). Make
sure the ends of these jumpers do not extend be-
yond the pad.
