Introducing the Optimus STAV-3560/3570
Your Optimus STAV-3560/3570 Digital Synthesized A/V Surround Receiver is
the perfect control center for your audio/video system. It combines 60 watts-perchannel (STAV-3560) or 100 watts-per-channel (STAV-3570) of clean power
with modern stylingl And, it 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.
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.
We recommend you record the receiver’s serial number here . The serial number is
on the receiver’s back panel.

Person in 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 RadioShack 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
Preparing the Speaker Wires
Follow these guidelines when you select
and connect speakers.
• Only connect speakers that are rated
at between 8 and 16 Ohms.
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.
• Be sure you properly connect all
speakers.
WireStrands
Strand
Wire
• 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.
• 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 a Subwoofer Amplifier (STAV-3570 Only)
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 connected to a subwoofer.
RadioShack 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 LOOP ANTENNA 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.

For better FM reception, you can also use a rabbit-ear TV antenna (for indoor
use only) or an outdoor VHF TV antenna. To connect the TV antenna to the
receiver, you need a VHF/UHF/FM splitter (not included). RadioShack stores
carry a full line of quality outdoor antennas and antenna connection accessories.
Preparing Your Receiver
Warning: To prevent injury, read and follow all cautions and warnings that
accompany the outdoor antenna.
For the best radio reception, use an outdoor antenna. Follow these steps to
connect an outdoor FM antenna to the receiver using 75Ω cable.
Note: If your antenna has 300Ω twin-lead cable, consult your local RadioShack
store for the correct adapter.
1. Disconnect the supplied FM antenna from the receiver’s FM UNBAL 75Ω
terminal.
2. With a stripping tool, remove about 1 1/2 inches of the 75Ω cable’s outer
insulation to expose the cable’s shielding.
3. Fold back the insulation from the inner insulation.
4. Remove about 1 inch of the inner insulation from around the center wire.

Basic Operation
Tuning the Radio
Note: For weak signals, we recommned
manual tuning.
Your receiver offers three types of electronic tuning — manual, automatic, and
memory.
Manual and Automatic Tuning
Follow these steps to manualy or automatically tune to the stations.
1. Press TUNER. Then press FM/AM to select the desired band.
The receiver tunes to and displays the frequency last selected in that
band.
2. Press TUNING or once to manually select the next higher or lower frequency. Or, press and hold down TUNING or to rapidly change freqeuncies. Release the button to stop.
To automatically search for the next higher or lower station, release TUNING as soon as the display starts to change. The receiver seaches up or
down the band to the next strong station.
Notes:
•
STEREO appears on the display for FM stereo broadcasts. TUNED
appears on the display when you tune to a strong station. To find a
weak FM station, press FM MONO until MONO appears. See “Using
FM Mono” on Page 16.
•
If you press TUNING at the top of the frequency range or TUNING
at the bottom of the frequency range, the display returns to the other
end of the range.
Memory Tuning
Memory tuning lets you instantly tune to a stored frequency. You can store up to
10 AM or FM frequencies in any of the three classes — up to 30 frequencies
total.
Follow these steps to store a station.
1. Press TUNER. Then press FM/AM to select the desired band.
Notes:
• If you store a frequency in a memory
that already contains a frequency, you
replace the previous frequency.
• If your receiver is disconnected from
AC power for several days, it loses all
the stored frequencies.
2. Using either manual or automatic tuning, select the frequency you want to
store.
If desired, press FM MONO for FM monaural sound (see “Using FM Mono”
on Page 17). This setting is stored in the memory.
3. Press MEMORY. MEMORY lights, and -- ch and the class number (1, 2,
or 3) flash on the display for about 5 seconds.
4. While MEMORY is on the display, press CLASS until the class number you
want (1-3) appears on the display. Then press STATION or until the
station number you want appears on the display. The station number
lights steadily, indicating the receiver memorized the frequency.
Repeat these steps to store additional frequencies.
To tune to a stored frequency, press CLASS so the desired class number
appears on the display, then press STATION / to select the station.
15
Basic Operation
Using FM Mono
To receive FM stations in stereo, press FM MONO until MONO disappears from
the display. STEREO appears on the display when you receive an FM broadcast
in stereo.
You can improve the reception of weak FM stations by pressing FM MONO until
MONO appears. This reduces noise while you listen to a weak FM station, but
you get monaural instead of stereo sound.
Balance Control
The BALANCE control lets you adjust the sound balance between the left and
right speakers. If you properly position the speakers and your listening area is
centered between them, the center control setting is usually best (see “Positioning Speakers” on Page 5).
For an unusual speaker placement, adjust BALANCE as follows:
1. Select TUNER. Then press FM/AM to select the FM band.
2. Press FM MONO until MONO appears. The sound is monaural instead of
stereo, so each speaker delivers the same output.
3. Turn BALANCE until you hear the sound coming equally from each
speaker when you are in the listening area.
4. Press FM MONO until MONO disappears from the display.
Muting the Receiver
To temporarily mute the sound, press MUTING on the remote control. MUTING
appears. Press MUTING again to restore the audio level.
Using Headphones
To listen with headphones (not supplied), insert the headphones’ 1/4-inch plug
into the receiver’s front panel PHONES jack. To silence the speakers, set A and
B SPEAKERS to the out position and turn off any special sound options.
Listening Safely
To protect your hearing, note the following when using headphones.
• Set the volume to its lowest setting before you begin listening. After you
begin listening, adjust volume to a comfortable level.
• Do not listen at extremely high volume levels. Extended highvolume listening can lead to permanent hearing loss.
• Once you set the volume, do not increase it. Over time, your ears adapt to
the volume level, so a volume level that does not cause discomfort might
still damage your hearing.
16
Cassette Deck/VCR Features
You can connect two cassette decks to the receiver. Selecting either VCR/TAPE
1 or TAPE 2 MONITOR lets you hear the playback from the cassette deck you
connected to the receiver’s corresponding (VCR/TAPE 1, TAPE 2 MONITOR)
jacks.
Using the VCR/TAPE 1

MONITOR , CD, TUNER, PHONO —to the VCR/TAPE 1 OUT (audio) and TAPE 2
MONITOR REC jacks (if you select VCR/TAPE 1 or LD/DVD, the audio and video
program are also sent to the TO MONITOR TV jacks).
The VOLUME control does not affect the level of the signal going to the tape
decks.
Dubbing a Cassette Tape
You can copy, or dub, a cassette tape from one cassette deck to another.
You can use either deck as the playback or recording deck. However, if you
want to monitor the cassette deck during dubbing, use the deck connected to
the VCR/TAPE 1 jacks as the source, and the deck you connected to the TAPE 2
REC jacks as the recording deck. Then press TAPE 2 MONITOR until TAPE 2
and the last program source you selected appear on the display. See “Using the

Care and Maintenance
Your Optimus STAV-3560/3570 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
RadioShack store for assistance.
24
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 RadioShack store for help
If you cannot eliminate the interference, the FCC requires that you stop using
your receiver.
