audiofrog AF-RLC Remote Level Control
Remote Level Control (Optional):
For one A600.1D and one RLC, plug one end of the RJ11 cord into the RLC and
the other end into the amplifier.
One RLC can control more than one A600.1D amplifier using a phone jack
splitter like the one shown below. Plug one connector into the RLC and plug
each of the other two into the RJ1l connectors on each of the amplifiers.
If you have more than two A600.1D amplifiers and yoU want to Use one RLC, you’ll need additional splifters. Connect as many as you need in the configuration shown below
If you need to control several amplifiers with a single-level control and you would prefer not to use a bunch of splitters, you can cut and splice the wires carefully. Be Sure to match the colors or pin positions carefully. The color code and pin-out Is provided below:
- No Connection
- Black (White/Orange Stripe)
- Red (Blue/White Stripe)
- Green (White/Blue Stripe)
- Yellow (Orange/White Stripe)
- No Connection
More about the RLC:
No audio signal is passed through the RJ11 cable. The RLC contains a
potentiometer that controls the gain of a voltage-controlled amplifier in the
A600.1D’s preamplifier circuit. Splitfing the signal between several
amplifiers doesn’t degrade the signal or reduce the amplifier’s performance.
If you’d like to make a custom control with a different potentiometer style or
a different knob, you can do so easily.
You’ll need an RJ11 phone cord from which yoU Can cuf one of the plugs so you
can solder the wires to the potentiometer. You’ll also need a dual-gang 20k0
log taper potentiometer. There are many styles from which you Can choose. An
example is shown here (right).
Connect the phone cord’s black, red, green and yellow wires to the
potentiometer according to the diagram below. Pins 2, 3, 5 and 6 must be
connected together and fo the black and green wires. Pin
must be connected to the yellow wire and pin 4 must be connected to the red
wire. You can connect several amplifiers to one potentiometer in this manner.
