plastic inserts and knobs.

INSTALLATION

Perform the following steps to install this volume control to your stereo system. These

instructions assume that you have already installed the speaker pair and low-voltage

mounting bracket at the desired locations.

1. Ensure that the amplifier is turned off and unplugged from its power source.

2. Run an in-wall rated speaker wire from the left-channel speaker to the low-voltage

mounting bracket.

3. Connect the wire to the left channel speaker, taking note of the wire colors or

markings used for the positive (+) and negative (-) connections.

For best results, always use the same wire colors or markings for the positive and negative

connections.
