AudioSource AE100VC - Manual

Note:

UL rated CL3 speaker wire is recommended when

running wire inside your walls. In many localities it may be

required by code. When installing your speaker wire, avoid

running the speaker wire parallel to any 120V power lines to

avoid picking up hum and interference from the power service.

If the speaker wire needs to cross a 120V power line at a

right angle this is acceptable and will not create a problem.

If you are uncomfortable with running the speaker wire yourself

in existing construction, it is recommended that you retain a

qualified custom home installation specialist or electrician.

Congratulations on your purchase of the AudioSource

AE100VC Impedance Matching Volume Control. This

product will allow you to install stereo speakers

throughout your home and control them, without

overloading your receiver or amplifier.

Please read this Manual to ensure the proper

installation and best performance of your AE100VC

Impedance Matching Volume Control.

Impedance Matching Volume Control

Function of the AE100VC

The AE100VC features high quality audio transformers,

removable solderless connection terminals and a

computer grade double-sided glass-epoxy printed circuit

board. An impedance matching switch multiplies the

impedance the amplifier “sees” by two, four or eight

times, allowing parallel connection of multiple AE100VCs

without damaging the amplifier. Twelve knob positions

provide a maximum of 39dB of attenuation. The AE100VC

package includes a metal mounting bracket, and three

sets of color matched knobs, plastic inserts, and screws.

Installation and Connection Procedures

Carefully choose the location for mounting the AE100VC.

For safety, and to avoid picking up hum and noise from

your electrical system, never put the AE100VC into the

same box as a light switch or dimmer.

Polarity (+/-) for the input and output speaker terminals

is clearly marked on the rear of the AE100VC. Speaker

wire is coded to identify each conductor as either

positive (+) or negative (-). This may be by color coding,

or one conductor may have a printed marking or a rib

along one edge that you will not find on the other. Identify

which type of polarity coding that your wire is using and

which conductor is positive (+) or negative (-).

1. Route the speaker cables from the amplifier and

each speaker pair to the location of the AE100VC paying

close attention to which wires connect to the speakers and

which connect to the amplifier. Mark them if needed.

2. Strip 3/8” insulation from the end of the cables and

twist the exposed ends to avoid fraying.

3. Remove the speaker and amplifier connectors from the

terminals marked Input and Output. Insert the wires into

their respective connector positions and tighten the screws.

4. Plug the connectors onto the circuit board terminals

being careful to observe markings for Input and Output.

If you are using a metal J-Box, insure that none of the

speaker wiring can short to the metal of the box.

Recommended Speaker Wire Gauges

The resistance of the speaker wire in your installation

can cause your speakers to perform at less than their

optimum quality level. Excess resistance caused by

using an undersized speaker wire can result in loss of

detail and definition in the bass region of your audio

program, as well as loss of dynamic range. Over extremely

long wire runs you may even experience a loss of high

frequency content in the audio signal.

To prevent sonic degradation in your speaker installation,

total speaker wire resistance should be kept below

0.5 ohms. The following table lists recommended speaker

wire gauge versus wire run length.

50’ or less - 16 Gauge 2-Cond. CL3 Rated

50’ - 150’ - 12 Gauge 2-Cond. CL3 Rated

150’ - 200’ - 10 Gauge 2-Cond. CL3 Rated
