HTS-105 Home Theater System

Your HTS-105 Home Theater System includes the STAV- 3770 receiver (RadioShack 31-3042, with its owner’s man- ual and accessories), two front speakers, two surround- sound (rear) speakers, one center-channel speaker, and one amplified subwoofer. All you need to add to have a complete home theater system are an audio/video input source (stereo Hi-Fi VCR or DVD/LD player) and a TV.

For receiver instructions and the HTS-105’s warranty, refer to the STAV-3770 Owner’s Manual. The instructions on the next few pages only cover basic home theater and speaker connections, and how to adjust the subwoofer controls. Before making any connections, see “Positioning Speakers” in the STAV-3770 Owner’s Manual to choose the best locations for your speakers.

Caring for Your Speakers

•Use a polishing cloth or dry cloth to wipe off dust and dirt.

•If the cabinet is very dirty, wipe it with a soft cloth dipped in a neutral cleanser diluted with water, then wipe again with a dry cloth. Do not use furniture wax or cleaners.

•Never use thinner, benzene, insecticide sprays, or other chemicals on or near the cabinets.

•Never use a vacuum cleaner to clean the grille cloth.

Your HTS-105 system includes all speaker wires required for speaker connections. Each speaker wire consists of two conductors (individual wires) encased in insulation and is color-coded so you can identify each conductor (the color mark is on only one of the conductors in each speak- er wire pair). Use these colors as a guide to help you prop- erly connect the speakers. (For subwoofer connection, use the supplied patch cable with phono plugs on both ends. Phasing is automatic.) For easy identification, your speakers are labeled FRONT and REAR.

If the supplied speaker wires are too short for your con- nections, you can purchase additional wire at your local RadioShack store. Use 16-gauge (or larger) speaker wire for all speaker connections.

When connecting each conductor to a speaker terminal, hold down the terminal lever, insert the conductor’s end into the small hole, and release the terminal lever to se- cure the conductor.

When connecting each conductor to the receiver, press open the terminal lever, insert the conductor’s end into the small hole, and press the lever closed to secure the con- ductor.

Notes:

•Be sure you connect the receiver’s right and left posi- tive (+) and negative (–) terminals to the speaker’s corresponding right and left positive (+) and negative

(–) terminals.

•Do not connect two pairs of speakers to a single set of terminals.

•Surround speakers generally sound best if you posi- tion them above ear level.
