OPERATING / SERVICE MANUALFVL 22

REMOTE VCA / LIMITER

QUICK START

Welcome to the section for all too busy to actually read the manual. We provide this quick

start as a service to our best customers (the ones who buy the product.) Let’s get started…

There are two ways to connect audio to the FVL 22, #6 terminal strips or Patch I/O points. To

use the terminals, attach the balanced lines to the “+”, “–”, and SHIELD GROUND terminals.

To run the FVL 22 unbalanced, attach the positive lead to the “+”terminal and leave the “–”

terminal open. To use the FVL 22 as an external level control/limiter for a mixer or other device

with tip = send, ring = return insert points, simple use the PATCH I/O¼" TRS jack. Note:

PATCH I/O is an unbalanced signal. Use two conductor cable with shield.

Install your remote control device (5k to 100k linear taper potentiometer, voltage ramp, or

switch) and run two or three wires to the FVL 22. If you are using an external voltage, run one

wire per Channel to the V1terminal for Channel 1, V2for Channel 2, and a ground wire to

COMMON GND. To use the provided 10VDC reference, connect a second wire from VREFlor

VREF2to your pot or switch. Refer to the wiring diagrams on the back page of this manual.

The VCA’s in the FVL 22 provide maximum attenuation of the signal level when a given

voltage is detected between Vl or V2 and COMMON GND. Reducing this voltage with a pot,

ramp, or switch increases the audio signal level. (0 volts or open = VCA full on.)

To calibrate: set the remote pot, ramp or switch to it’s maximum voltage. Adjust the VOLT-

AGE CALIBRATIONcontrol until the green CALindicator is lit.

Rotate the LIMITERthreshold control to the level you never wish to exceed at the output.

The AUTO-SLAVEswitch position locks the limiter control circuitry for stereo applications,

limiting both Channels equally when either Channel goes into limit.

Upon completion of the setup procedures, use the supplied hole plugs to prevent unautho-

rized adjustments.

Never connect anything except an approved Rane AC Power supply to the thing that looks

like a red telephone jack on the rear of the FVL 22.This is an AC power input and requires

special attention if you do not have a power supplyexactlylike the one originally packed with

your unit. Rane models FRS 8, RAP 10 or VC 18 power supplies are acceptable as well. Please

see the full explanation of power supply requirements elsewhere in this manual.

SYSTEM CONNECTION

When connecting the FVL 22 to other components for the

first time, leave the power supply for last. This allows for

mistakes to be identified by visual inspection and corrected

before power is applied and it becomes too late.

INPUTSand OUTPUTSon the FVL 22 are connected

via terminal strips or the PATCH I/O jack. Using the termi-

nals, attach the balanced lines to the “+”, “–”, and SHIELD

GROUND terminals. To run the FVL 22 unbalanced, attach

the positive lead to the “+”terminal and leave the “–”

terminal open. To use the FVL 22 as an external processor for

a mixer of other device with tip = send, ring = return insert

points, use the PATCH I/O ¼" TRS jack with a two conductor

shielded cable (the PATCH I/O is unbalanced).

EXTERNAL VCA CONTROL. The VCA’s in the FVL

22 provide maximum attenuation of the signal level when a

voltage is detected between V1 and V2 and COMMON GND.

Reducing this voltage with a pot, voltage ramp, or switch

increases the audio signal level. (0 volts or open = full VCA

on.) This voltage is provided by the VREF terminal on the

FVL 22 or derived by existing voltage sources at the remote

device location. Refer to the wiring diagrams on the last page

of this manual.

POWERING UP. A good visual inspection often elimi-

nates disasters before applying power. It cannot be overstated

how important it is to use the correct power supply with this

and all Flex products. The RS 1 single AC power supply

(included with each module) as well as the Rane FRS 8, RAP

10 and VC 18 power supplies are the only supplies certain to

work properly with the unit. If another supply is considered, it

must be an AC supply. It must have an 18 to 24 volt center-

tapped output and be wired to a 6-in mod connector in

accordance with the requirements of the Rane standard.
