OPERATORS MANUAL

QUICK START

Shredded, this document makes excellent packing material. In

its present form, it makes interesting and useful reading. If you

run out of patience quickly, at least read this part to make sure

you don’t exterminate everything within a two mile radius by

doing something wrong.

First, be sure the POWER switch is off. Attach one or two

channels of Inputs and Outputs to the respective connectors on

the rear. This device uses low impedance balanced line drivers. Do

not

connect the XLR “+” or “–” output pins to ground, as this may

cause the power supply to shut down. For unbalanced use, leave the

unused output pin (“+” or “–”) unterminated. OK, now you can

power up your sound system, volumes down, amp turned on last.

With the GATE THRESHOLD turned all the way down to

-80 dBu

, COMPRESSOR THRESHOLD turned all the way

up to 20 dBu, COMPRESSOR RATIO turned all the way

down to 1, and the OUTPUT LEVEL control in the center at 0

dB,

you have an expensive patch cord.

While sending a signal to the DC 22S, adjust the output

level of the previous device so the +4 dBu LED lights occasion-

ally, but the OL LED does not light. If you are driving the ¼"

WEAR PARTS: This product contains no wear parts.

DC 22S

STEREO COMPRESSOR

INPUTS with a balanced signal (tip-ring-sleeve), set the Input

Gain switch to +4 dBu (in). When driving this input with an

unbalanced signal (tip-sleeve), set this switch to –10 dBv (out).

Regardless of the type of Input, you might need to set this switch

so the INPUT LEVEL LEDs light correctly.

Now increase the COMPRESSOR RATIO to something

useful, like 2:1 (with the control set at 2, the Ratio is 2:1; at 5, it

is 5:1.) Adjust the COMPRESSOR THRESHOLD to the point

you want the Compressor to kick in. The GAIN REDUCTION

meter reads the amount of signal compression.

If you want the quiet parts to be even quieter, increase the

GATE THRESHOLD

so only higher levels make it through the

Gate.

Both Gates and Compressors will activate by the source

material applied to either channel if the LINK switch is on. This

is the preferred setting for stereo program material. The chan-

nel 1 controls set both channels to the same adjustments, as the

channel 2 controls go dormant and the LEDs extinguish. If

the LINK switch is off, then both channels are independently

controllable.
