INPUT, OUTPUT, AND POWER CONNECTIONS
This equalizer should be connected to a 3 wire grounded outlet supplying 120
Volts, 50-60 Hz. Power consumption is 12 watts.
The INPUT is a 10K ohm active balanced type on a standard stereo phone plug.
The (+) or in-phase connection is on the tip and the (-) or out-of-phase
connection is on the ring. When feeding the equalizer from unbalanced
sources, connect the signal hot to the tip ( + ) and the signal ground to the
ring (-). To use the input as a common unbalanced type, simply use a mono
phone plug in the usual way. (See Definition Of Terms, "Wiring", page 17.)
The OUTPUT connections are standard 1/4" phone jacks and mate with a standard
phone plug such as a switchcraft 280. For rack mounted unbalanced audio
systems the output ground may be separated from the case ground by using a
stereo phone plug for the output connection. The output ground is then wired
to the ring of the stereo phone plug for the output connection. The output
ground is then wired to the ring of the stereo plugs rather than the sleeve.
In this manner, ground loops in the rack may be eliminated. This output can
be fed to a balanced input by wiring the ( + ) input to the tip, the (-) input
to the ring, and the shield to ground.
If this equalizer is used in a monaural system, channels 1 and 2 of the SC-66A
may be cascaded to utilize all eight bands of equalization. Connect the input
signal to channel 1 input, connect channel 1 output to channel 2 input, and
take the output signal from channel 2 output. If the audio ground plug
isolation is needed for rack mounting, use a stereo phone plug jumper to
connect channels 1 and 2.
