Introducing the Optimus STAV-3670
Your Optimus STAV-3670 Audio/Video Receiver is the perfect control center for
your audio/video system. It combines 100 watts-per-channel of clean power
with modern styling 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 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.
30 Memory Locations Let you store and recall the frequencies for up to 30 AM/FM stations.
Automatic Tuning Searches for the next available AM/FM station.

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 front speakers at
the front of your listening area, and place the (rear) surround speakers behind
or to the sides of the listening point (see “Using Advanced Sound Options” on
Page 20). 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.
• Only connect speakers that are rated
at between 8 and 16 Ohms.
• 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.
• 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.
6
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.

Connecting Surround-Sound Speakers
You can connect a pair of speakers to the receiver for surround-sound programs. Follow the steps in “Connecting the A and B Speakers” to connect the
speakers to the REAR SPEAKERS terminals.
Connecting the Center Speaker
The center speaker gives additional ambience to surround sound. Follow the
steps in “Connecting the A and B Speakers” to connect the center speaker to

Connecting a Subwoofer 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 the subwoofer output, simply connect SUBWOOFER to an amplified subwoofer’s linelevel input or to an amplifier to which you have connected a subwoofer.
RadioShack stores sell a variety of suitable subwoofers and amplifiers.

In many areas, the supplied indoor AM loop and FM antennas provide satisfactory reception.
AM Antennas
Assemble the supplied AM 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. 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.
Attach the antenna wires to the AM LOOP ANTENNA and
(right two terminals).
(ground) terminals

Your receiver offers three types of electronic tuning — manual, automatic, and
memory.
Manual and Automatic Tuning
Follow these steps to manually 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, hold down TUNING or to rapidly change frequencies.
Release the button to stop.
To automatically search for the next higher or lower station, release TUNsoon as the display starts to change. The receiver searches up or
down the band to the next strong station.
ING as
Notes:
•
TUNED appears when you tune to a strong station.
•
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.
•
Automatic tuning works for FM stations only.
Memory Tuning
Memory tuning lets you store up to 30 AM or FM frequencies in three different
classes (10 frequencies in each class), then instantly tune to a stored station.
Follow these steps to store a station in a memory location.
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. Use either manual or automatic tuning to select the frequency you want to
store.
If desired, press FM MONO for FM stereo or monaural sound (see “Using
FM MONO” on Page 16). This setting is also stored in memory.
3. Press MEMORY. MEMORY lights, and - (for the channel number) and the
class number (1, 2, or 3) flash on the display for about 5 seconds.
4. While MEMORY appears, press CLASS until the class number you want (1,
2, or 3) appears, then press STATION or until the channel number you
want appears.
The class and station numbers light steadily, indicating the receiver memorized the frequency.
To tune to a stored station, press CLASS so the desired class number appears,
then press STATION / to select the station.
Basic Operation
Using FM MONO
16
To receive FM stations in stereo, press FM MONO so MONO disappears from the
display. STEREO appears 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 so 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 so 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, press
SPEAKERS A and B so you can listen with headphones without disturbing others.
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 the 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.
17
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 1or TAPE 2 MONITOR) jacks.
Using the VCR/TAPE 1 and
TAPE 2 MONITOR Buttons
Press VCR/TAPE 1. VCR appears on the display. You hear the playback from the
cassette deck or VCR you connected to the receiver’s VCR/TAPE 1 IN jacks.
Press TAPE 2 MONITOR. TAPE 2 appears on the display along with the last program source you selected. You can hear playback or monitor a recording from
the cassette deck you connected to the receiver’s TAPE 2 MONITOR jacks. The
TAPE 2 MONITOR REC jacks continue to output sound from the previously selected
source when you press TAPE 2 MONITOR.
To return to the previous source, press TAPE 2 MONITOR again so TAPE 2 disappears.
Notes:
• If you press TAPE 2 MONITOR when that cassette deck is neither playing nor
recording, the receiver mutes the current audio source. To hear the audio
source, press TAPE 2 MONITOR so TAPE 2 disappears from the display.
• Do not press TAPE 2 MONITOR while you are recording on the deck connected to TAPE 2 MONITOR REC. If you do, the recording is interrupted for
about 1 second.
Recording an Audio Source
The receiver sends the audio of the program source you select— VCR/TAPE 1,
CD , LD/DVD, TUNER , or PHONO —to the VCR/TAPE 1 OUT (audio) and TAPE 2 MONITOR REC jacks (if you select VCR/TAPE 1 or LD/DVD, the video program is also sent
to the TO MONITOR TV jack).
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 so TAPE 2 and the
last program source you selected appear on the display. See “Using the VCR/
TAPE 1 and TAPE 2 MONITOR Buttons.”
18
Cassette Deck/VCR Features
Playing and Recording
Video Tapes
You can connect two video sources to the receiver. If you connect a VCR to the
VCR/TAPE 1 and LD/DVD audio and video jacks, you can copy video cassette
tapes from one VCR to another and monitor the dubbing process.
Playing a Video Tape
To play a video tape, load the tape into the VCR connected to either VCR/TAPE 1
or LD/DVD. Press the button (VCR/TAPE 1 or LD/DVD) that corresponds to the jack
the VCR is connected to. VCR or LD/DVD appears on the display. Follow the
VCR’s instructions to begin playback. If you connected a monitor to the
receiver’s TO MONITOR TV jack, you can view the program on that monitor.
Copying a Video Tape
Follow these steps to copy a video tape from one VCR to another.
1. Load the tape you want to copy into the VCR connected to LD/DVD.
2. Load a blank tape (or one you want to record over) into the VCR connected to the VCR/TAPE 1 jacks.
3. Press LD/DVD.
4. Begin recording and playback on the VCRs.
Important: Most material performed in public, such as concerts, plays, and
movies, or distributed on prerecorded video tapes is copyrighted. The unauthorized recording or duplication of copyrighted material is a violation of the copyright laws of most countries and such duplication may result in fines,
imprisonment, or both. Note, however, that in the United States, it is not a violation of U.S. copyright laws for a consumer to record a broadcast television program for private (in-home) viewing.
19
Using Advanced Sound Options
Your receiver has four special sound options: Dolby Pro Logic Surround, Dolby
3CH Logic, Studio-Effect Surround, and Simulated Surround. These special
options enhance a program source.
Notes:
• To get the full benefit from programs encoded with Dolby Surround
Sound, you need a stereo VCR.
• Dolby Surround does not operate correctly if the signal passes through a
graphic equalizer. If you connected an equalizer to the TAPE 2 MONITOR
jacks, do not select TAPE 2 MONITOR when you listen to Dolby Surround
signals.
To activate Dolby Pro Logic Surround or Dolby 3CH Logic, press DOLBY PRO
LOGIC, then press CENTER MODE on the remote control to select the Dolby Pro
Logic options (normal, wide, or phantom) or Dolby 3CH Logic.
For studio effect or simulated surround, press SFC MODE until the desired option
appears on the display. On the remote control, press SURR MODE to select the
sound options; when you select the Dolby Pro Logic, use CENTER MODE to make
a selection (see “Sound Mode Adjustments (Remote Control Only)” on
Page 21).
Dolby Pro Logic Surround
Dolby Pro Logic Surround puts you in the middle of the action. The center- and
rear-channel speakers add incredible realism by directing the sound to the
appropriate speakers, making you feel like you are really there. You can find
hundreds of movies, television shows, and compact discs produced with Dolby
Surround.
Dolby 3CH Logic
Dolby 3CH Logic produces a more spacious sound field than is possible with
ordinary stereo playback, by combining the front and rear speaker sounds.
Select this mode when you play a Dolby Surround Sound program and do not
have rear speakers. The rear channel’s sound is sent to the front left and right
speakers.
Studio Effect
Studio Effect gives the effect of listening in a recording studio. The front speakers provide normal stereo, and the rear speakers provide a subtly reverberated
sound. Select this mode when you listen to sources not encoded with Dolby
Surround.
Simulated Surround
Simulated Surround simulates a surround effect when you listen to a monaural
(mono) source.

Care and Maintenance
Your Optimus STAV-3670 Audio/Video 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.
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.
25
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.

HEREIN, RadioShack MAKES NO EXPRESS WARRANTIES AND ANY IMPLIED WARRANTIES,
