OPERATING / SERVICE MANUAL FSC 22

STEREO COMPRESSOR

QUICK START

These virgin pages tremble at your touch. You’re eyes, the first. Their desperate inquisitive

scanning overwhelms. The summer air burns with anticipation. Do what you must, but what-

ever you do, don’t stop...PLEASE DON’T STOP...reading that is, at least this section before

you torch it.

Here’s some quick highlights:

Set the rear INPUT TRIM switch for the appropriate gain for your signal levels. Don’t be

thrown by the combo Input connectors; they take either ¼" TRS or 3-pin (XLR-type) plugs.

Both Output connectors may be used at the same time if needed, e.g., splitting to different

zones, etc.

Be sure the SYSTEM MODE switch is in its out (DUAL) position, as are the BYPASS

switches. Initially press the METER MODE switch in. Now the meter reads Output Level in

dBu—very useful during set-up. Remember to switch it out when through, so it returns to its

main role of displaying Gain Reduction.

Set the LEVEL controls to “7” for unity gain—a good place to start. Use the BYPASS

controls to A-B levels.

When used with true stereo program, press the SYSTEM MODE switch in to the SLAVE

position. This causes both Channels to operate equally if either exceeds its THRESHOLD

setting.

NEVER CONNECT ANYTHING EXCEPT AN RS 1 OR OTHER APPROVED RANE AC

POWER SUPPLY TO THE RED CONNECTOR THAT LOOKS LIKE A TELEPHONE JACK ON

THE REAR OF THE UNIT. This is an AC input and requires special attention if you do not

have an operational power supply EXACTLY like the one originally supplied with your unit. A

Rane Model FRS 8 or RAP 10 power supply is acceptable as well.

SYSTEM CONNECTION

Locating the FSC 22 in your system depends on the

application. When assembling a sound reinforcement system,

place the FSC 22 between the equalizer (if used) and the

active crossover, or the power amplifier if using passive

crossovers.

In recording applications, locate the FSC 22 in the insert

loops on the mixing console, or in series with the outputs

before the recorder. Most consoles allow headphone monitor-

ing of the processed signal (i.e., post inserts). A most useful

feature.

When using the FSC 22 on mixdown, connect it to the

output of the multichannel recorder, or in the inserts of the

mixdown console.

Many recording situations require connecting the FSC 22

to the patch bay in the system. This makes it easy to move

from one signal path to another, as new applications dictate.

Use only fully balanced wiring of this and all components,

without signal ground ever connecting between units. All

shields should be chassis, i.e., earth grounded. Consult Rane

Note 110, an application guide available from Rane Corpora-

tion or your local Rane dealer. This note details standard

wiring conventions which help reduce noise and distortion.

FRONT PANEL DESCRIPTION

1. RATIO CONTROL. This rotary control determines the slope of the compressor for

signals exceeding threshold. Full counter-clockwise rotation of the RATIO control

disables all Compressor activity.

2. DUAL FUNCTION METER. This six segment LED meter indicates either Gain

Reduction or Output Level as determined by the position of the Meter Mode

Switch. GAIN REDUCTION mode displays the amount of reduction (below

unity) applied to the audio signal by the VCA. OUTPUT mode displays the

balanced output level in dBu, i.e. where 0dBu = 0.775 Vrms.

3. METER MODE PUSHBUTTON. The out, or disengaged, position selects GAIN

REDUCTION meter mode. The in, depressed, or engaged, position selects

OUTPUT meter mode.

4. THRESHOLD LED. This yellow LED illuminates any time the input signal

exceeds the THRESHOLD setting.

5. THRESHOLD CONTROL. The position of this rotary knob determines above

what input level the Compressor/Limiter functions.

6. BYPASS LED. A red LED indicating the BYPASS switch is engaged.

7. BYPASS SWITCH. A passive switch used to bypass all active circuitry in this

channel. Press in to Bypass. Useful for A-B comparisons and to restore signal path

should power fail.

8. SYSTEM RESPONSE SWITCH. Use this pushbutton to select the desired attack/

release response. Out chooses SLOW; in chooses FAST.

9. SYSTEM MODE SWITCH. In the in (SLAVE) position, this switch causes both

Channels’ Compressors to act together, i.e., they are “slaved”. All controls for both

Channels remain active, so independent settings are still possible; however,

whenever a signal in either Channel exceeds its setting, then both Channels change

by the same amount. In the out (DUAL) position, both Channels operate indepen-

dently.

10. OUTPUT LEVEL CONTROLS. This concentric control increases or decreases

the output Level for each Channel. Up to 10dB of gain is available. Unity gain is

about “7” for balanced outputs, and “8” for unbalanced outputs.

11. OVERLOAD LEDS. Illuminates any time either output signal gets to within about

4dB of clipping. Occasional flickering is okay, continuous is not.

12. POWER INDICATOR LED. Hey, if it’s lit, you’re fit; if not, call a doc. And

while we’re on the subject of power, let me take this opportunity to tell you just

what I think about runaway government ...
