Introducing the Optimus STAV-3370
Your Optimus STAV-3370 Digital Synthesized A/V Surround Receiver is the perfect control center for your audio/video system. It combines 110 watts-per-channel of clean power with modern styling and provides connections for one tape
deck, one audio/video source, one more tape deck or audio/video playback
source, a turntable, a CD player, and a video monitor.
Your receiver also has four special sound options. Dolby Pro-Logic Surround
Sound delivers movie theater sound for audio/video programs (especially those
encoded with Dolby Surround Sound signals). Dolby 3CH Logic provides a
wider sound field than ordinary playback. Studio Effect simulates the ambiance
of a recording studio, adding extra richness to your music. Simulated Surround
gives you a surround-sound effect even when you listen to monaural sources.
Additional features include:
Digital-Synthesized Tuner Precisely tunes to AM and FM stations.
Multi-Jog Tuning Offers you a simple tuning method for either memorized stations or the entire
frequency range.
Automatic Tuning Searches for the next available AM/FM station.
30 Memory Locations Let you store and recall the frequencies for up to 30 AM/FM stations.
Super Bass Creates a richer, fuller sound by enhancing the bass portion of the program.
Tape Monitoring Lets you listen to the actual recording as you record, if your tape deck has a
tape-monitoring feature.
Built-In Protection Circuits Turn off the receiver to help prevent damage if a power surge or short circuit
occurs.
Remote Control Lets you use a single remote control for the receiver and other compatible components connected to the receiver.
Display Blanking Lets you turn off the display so the light does not disturb you in low-light situations.
For your records, record the receiver’s serial number in the space provided. The
serial number is on the receiver’s back panel.

Main Listening Area
Where you place your speakers (not supplied) can make a noticeable difference
in your system’s sound. The guidelines in this section will help you choose the
best locations. After you use your receiver for a while, you might want to try different locations for your speakers.
Bass response depends largely on speaker location. For strong bass, place the
speakers in the corners of the room. If you want even stronger bass, place the
speakers directly on the floor. If the bass is too strong, move the speakers
slightly away from the corners of the room, or raise them 6 to 18 inches off the
floor. You can buy speaker stands at your local Radio Shack store.
The distance between the speakers should be about the same as the distance
between the normal listening point and the point halfway between the speakers.
If you place the speakers too close together, you reduce the stereo separation.
If you place them too far apart, you reduce the bass effect and create a hole in
the middle of the sound.
• Surround speakers generally sound
best if you position them above ear
level.
Most speakers have a tweeter dispersion angle of about 60 degrees. Ideally,
your listening position should be just inside the overlap area of the tweeter dispersion. You can angle the speakers toward you for better stereo effect.
• To avoid interference with the picture
on a nearby TV, use magnetically
shielded speaker systems. This is particularly important for the center
speaker since it is usually located
closest to the TV.
To position your speakers for surround sound, place the A or B speakers at the
front of your listening area, and place the surround speakers behind or to the
sides of the listening point (see “Using Advanced Sound Options”). Also, place
the center speaker above, below, or behind the TV. Sound might not appear to
coincide with the picture if you place it beside the TV.

Preparing Your Receiver
Connecting Speakers
Follow these guidelines when you select
and connect speakers.
• Be sure you properly connect all
speakers.
• Do not connect two pairs of speakers
to a single set of terminals (A or B) at
the same time. When you use two
pairs of speakers, connect one set to
Speakers A and one set to Speakers B.
Preparing the Speaker Wires
Speaker wire consists of two conductors (individual wires) encased in insulation
and is usually color-coded or marked with a ridge along one side so you can
identify each conductor. Use these markings as a guide to help you properly
connect the speakers to your receiver.
Follow these steps to prepare the speaker wires.
• Realistic, Optimus, and other highquality speakers have color-coded
speaker terminals (red for positive
polarity and black for negative polarity). Use these color-coded terminals
as a guide to help you properly connect the speakers to the receiver.
• Use 16-gauge (or larger) speaker wire
for all speaker connections, and consider possible speaker locations
before you decide how much speaker
wire you need.
1. Cut the speaker wires to the necessary length.
2. Separate the wires about 4 inches on each end.
3. Using a wire stripper, carefully strip about 3/4 inch of insulation from the
end of each conductor.
4. Twist the end of each conductor to secure any loose wire strands.

Preparing Your Receiver
Connecting the A and B Speakers
Note: Be sure you connect the
receiver’s right and left positive (+) and
negative (–) terminals to the speaker’s
corresponding right and left positive (+)
and negative (–) terminals.
Follow these steps to connect the right speaker to the receiver’s right FRONT
SPEAKERS A terminals.
1. Press the receiver’s FRONT SPEAKERS A R (+) red lever and insert the
ridged or color-coded conductor’s end into the small hole. Pull back the
lever to secure the conductor.
2. Press the receiver’s FRONT SPEAKERS A R (–) black lever and insert the
other conductor’s end into the small hole. Pull back the lever to secure the
conductor.
3. Connect the ridged or color-coded conductor’s loose end to the right
speaker’s positive (+) terminal.
4. Connect the remaining loose conductor to the right speaker’s negative (–)
terminal.
Repeat Steps 1 through 4 to connect the left speaker to the receiver’s FRONT
SPEAKERS A L terminals.
Repeat this entire process to connect a second pair of speakers to the FRONT
SPEAKERS B terminals.
Connecting Surround-Sound Speakers
You can connect a pair of speakers to the receiver’s REAR SPEAKERS terminals
for surround-sound programs. Follow the steps in “Connecting the A and B
Speakers.”
Connecting the Center Speaker
The center speaker gives additional ambience to surround sound. Connect the
center speaker to the CENTER SPEAKER terminals. Follow the steps in “Connecting the A and B Speakers.”
Connecting Center Channel and Subwoofer Amplifiers
To increase the center channel’s output power, you can connect an amplifier to
the CENTER jack, as shown. Then connect the center channel speaker to the
amplifier.
Your receiver includes a line-level subwoofer output. Connecting a subwoofer to
your system dramatically extends bass response for incredible richness and
depth. When you listen to surround-sound programs, a subwoofer enhances
your home theater experience by realistically recreating the rumble of an earthquake, the bone-jarring percussion of a cannon, and more.
To use this output, simply connect it to an amplified subwoofer’s line-level input
or to an amplifier to which you have connected a subwoofer.
Radio Shack stores sell a variety of suitable subwoofers and amplifiers.

Preparing Your Receiver
Connecting the Antennas
In many cities, the supplied indoor AM loop and FM antennas provide adequate
reception.
AM Antennas
Assemble the included antenna’s base by swinging the base in the direction of
the arrow and inserting the antenna’s bottom tabs into the base’s slot. Then
attach the antenna wires to the AM and GND terminals (bottom two terminals).
Place the antenna on a flat surface and rotate it for the best AM reception.
If the receiver is in a rack or on a shelf and there is no room for the AM loop
antenna, use two screws (not supplied) to mount the base on the wall or
another location as shown.
Notes:
• Keep the AM loop antenna connected even when you use another indoor
antenna or an outdoor AM antenna.
• Ensure the antenna does not touch the receiver or other metal objects.
• Do not place the antenna near a CD player, a personal computer, or a TV
set

Care and Maintenance
Your STAV-3370 Digital Synthesized A/V Surround Receiver is an example of superior design and craftsmanship. The following
suggestions will help you care for the receiver so you can enjoy it for years.
Keep the receiver dry. If it gets wet, wipe it dry immediately. Liquids can contain
minerals that can corrode the electronic circuits.
Handle the receiver gently and carefully. Dropping it can damage its circuit
boards and can cause the receiver to work improperly.
Use and store the receiver only in normal temperature environments. Temperature extremes can shorten the life of electronic devices, damage batteries, and
distort or melt plastic parts.
Keep the receiver away from dust and dirt, which can cause premature wear of
parts.
CLEANER
Wipe the receiver with a damp cloth occasionally to keep it looking new. Do not
use harsh chemicals, cleaning solvents, or strong detergents to clean the
receiver.
Use only fresh batteries of the recommended size and type in the remote control. Always remove old or weak batteries. They can leak chemicals that can
destroy electronic circuits.
Modifying or tampering with your receiver’s internal components can cause a malfunction and might invalidate the receiver’s
warranty and void your FCC authorization to operate it. If the receiver is not operating as it should, take it to your local Radio
Shack store for assistance.
26
The FCC Wants You To Know
Your receiver might cause radio or TV interference even when it is operating
properly. To determine whether your receiver is causing the interference, turn off
your receiver. If the interference goes away, your receiver is causing it. Try to
eliminate the interference by:
• Moving your radio or TV away from the receiver
• Connecting your receiver to an outlet that is on a different electrical circuit
from the radio or TV
• Contacting your local Radio Shack store for help
If you cannot eliminate the interference, the FCC requires that you stop using
your receiver.
