1. Frequency Selection

the signal both in and out of the mixer/amplifier combination. The insert

points are interrupting, meaning the insertion of a plug will interrupt the signal

going to the amplifier. The tip is the return, or input to the amplifier, while the ring

is the send, or output of the mixer.

EXTERNAL PROCESSING

To place an external processor in the loop, first you need to obtain or make

a special three conductor cable which is terminated on one end with a stereo TRS

(tip-ring-sleeve) 1/4" plug, and terminated on the other end with two mono TS (tip-

sleeve) 1/4" plugs. The shield at the TRS end must connect to the sleeve of each

mono plug. The tip from the insert point connects to one mono tip (return), while

the ring (send) from the insert point connects to the other mono plug's tip (see

figure 8). Remember to identify which mono plug is send and which is return. As

these are unbalanced signals, avoid running them more than ten or fifteen feet to

the outboard processor. Any greater distance may increase hum susceptibility. If

at all possible, always mount external processing in the same rack as the power

amplifier to minimize the chance for ground loops in the system.

AUX OUTPUTS

If you wish to tap the mixer's output for external use without disturbing the

signal sent to the amplifier, as in driving a tape deck or auxiliary amplifier, the

procedure is similar. Make a cable with a stereo plug on one end, only connect

together the tip and the ring. This is the hot signal to whatever device you are

driving. Keep the cable length to a minimum and avoid ground loops by the same

techniques as mentioned above. Connect the shield to the sleeve as you would any

signal cable and terminate it at the other end according to your needs.

MIXER OVERRIDE

You can override the mixer by simply inserting a mono plug with your

external source on the tip. This feeds directly to the power amplifier without any

level control on the amp itself. Again, this is an unbalanced input, so follow the

techniques mentioned above for minimum noise and ground loop hum.
