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 RJ11 connectors on

each of the amplifiers.

To A600.1D

If you have more than two A600.1D

amplifiers and you want to use one RLC,

you'll need additional splitters. Connect

as many as you need in the configuration

shown below

To A600.1D

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:

1: No Connection

2: Black (White/Orange Stripe)

To RLC

3: Red (Blue/White Stripe)

4: Green (White/Blue Stripe)

5: Yellow (Orange/White Stripe)

6: 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. Split-

ting 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 differ-

ent knob, you can do so easily.

To RLC

You'll need an RJ11 phone cord from

which you can cut one of the plugs so you

can solder the wires to the potentiometer.

You'll also need a dual-gang 20kΩ log ta-

per 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 potentiom-

eter according to the diagram below. Pins

2, 3, 5 and 6 must be connected together

and to the black and green wires. Pin 1

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.
