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.
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.
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.
• Never use thinner, benzene, insecticide sprays, or
other chemicals on or near the cabinets.
• Never use a vacuum cleaner to clean the grille cloth.
Connecting Speakers
Center Speaker
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.

Use the supplied single patch cable to connect the receiver’s SUBWOOFER/PRE OUT jack to the subwoofer’s LINE LEVEL INPUT
jack. Then connect the subwoofer’s power cord to a standard AC outlet or the receiver’s SWITCHED outlet. The subwoofer’s
POWER indicator lights when the power is on.
Wall Mounting the Speaker System
To mount the speakers on a wall, you need wood screws with heads that fit into the keyhole slot on the back of each speak-
er. Make sure the wall surface and screws you use are appropriate for the weight of the speakers. Keep in mind that the
speaker’s vibration will affect the surface, so we do not recommend mounting on plywood boards or other soft-surface
walls.

Drill a hole and thread a screw into the wall, letting the head extend about / inch (6 mm) from the wall. Align the keyhole
slot with the mounting screw and slide the speaker downward to secure it.

Adjusting the Subwoofer Level
You can adjust the subwoofer sound level independently from the other speaker’s level. Rotate LEVEL on
the back of the subwoofer clockwise to increase the volume; counterclockwise to decrease it.

Note: Always set to MIN before you begin listening, then increase the level slowly. If the system is turned
on with the volume set too high, it can cause damage to hearing or to the speaker. Take care not to in-
crease the volume at the receiver (including BASS or LOUDNESS controls) with the subwoofer’s LEVEL
set at the MAX position: the signal level might reach a clipping level, causing damage to the subwoofer’s
amplifier or speaker element.
