Introducing the Optimus STAV-3780
Your Optimus STAV-3780 Audio/Video Receiver operates as the perfect
control center for your audio/video system. It combines 100 watts-perchannel of clean power with modern styling. It provides connections for
one tape deck, one VCR, two audio/video sources, a turntable, a CD
player, and two TV’s or video monitors.
Your receiver 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). DSP Effects
creates a listening environment that simulates a concert hall, jazz club,
theater, or a dance hall. Virtual Dolby Surround uses TruSurround technology to provide a three-dimensional sound field using only the front
left and right speakers. 5-D Theater provides clear dynamic sound effect
by sending audio signals through the rear channel to simulate stereo
sound.
In addition, you can connect a multi-channel decoder or DVD player
with 5.1-channel output so that all five channels and the subwoofer
have independent signals.
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.
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 Automatically turn off the receiver to help avoid power surges or short
circuit damage.
Remote Control Lets you use a single remote control for the receiver and other compatible components connected to the receiver.
Note: The remote control requires two AA batteries (not supplied).
We recommend you record the receiver’s serial number here. The number is on the receiver’s back panel.

Normal Listening Point
• Surround speakers generally sound
best if you position them above ear
level.
• To avoid picture interference of 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.
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.
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 position your speakers for surround sound, place the 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 22). Place the center speaker above, below, or
behind the TV. If you place it beside the TV, the picture may not coincide with the sound.

Connecting Speakers
Preparing the Speaker Wires
Follow these guidelines when you select
and connect speakers.
• Only connect speakers that are rated
at between 6 and 16 Ohms.
• Be sure you properly connect all
speakers.
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.
• Do not connect two pairs of speakers
to a single set of terminals at the
same time.
• Optimus and other high-quality 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.
Wire Strands
Speaker Wire
Wire Strands
Conductor
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.
Setting the Impedance Selector Switch
Before proceeding to speaker connection, be sure to set the IMPEDANCE
SELECTOR switch to the appropriate position. If you connect speakers
with 6- to 8-ohm impedance, set the switch to 6~LESS THAN 8 W position. If
you are using 8- to 16-ohm impedance, set it to 8~16 Ω position.

and negative (–) terminals.
Follow these steps to connect the right speaker to the receiver’s right
FRONT SPEAKERS terminals.
1. Press open the receiver’s FRONT SPEAKERS R (+) red lever and insert
the ridged or color-coded conductor’s end into the small hole.
Press the lever closed to secure the conductor.
2. Press open the receiver’s FRONT SPEAKERS R (–) black lever and insert
the other conductor’s end into the small hole. Press the lever
closed 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 1–4 to connect the left speaker to the receiver’s
SPEAKERS left terminals.

Connecting Surround-Sound Speakers
You can connect a pair of speakers to the receiver for surround-sound
programs. Follow the steps in “Connecting the Front Speakers” to connect the speakers to the SURROUND SPEAKERS terminals.
Connecting the Center Speaker
The center speaker gives additional ambience to surround sound. Follow the steps in “Connecting the Front Speakers” to connect the center
speaker to the CENTER SPEAKER terminals.
Or, if you are intending to use the amplified speaker as your center
speaker, connect CENTER PRE OUT to its line-level input. You can also connect this jack to the audio input of your TV.
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 PRE OUT to an amplified subwoofer’s line-level input or to an
amplifier to which you have connected a subwoofer.
RadioShack stores sell a variety of suitable subwoofers and amplifiers.

Using Advanced Sound Options
Your receiver has four special sound options: Dolby Pro Logic Surround,
Dolby 3CH Logic, DSP Effect, and Dolby Virtual. These special options
enhance the sound from a connected program source.
Notes:
• To get the full benefit from programs encoded with Dolby Surround Sound, you need a stereo audio/video source.
• 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.
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. Pro Logic is the standard for surround sound systems. Dolby
3CH LOGIC produces a more spacious sound field than is possible with
ordinary stereo playback by sending the rear channel’s sound to the
front left and right speakers. Select 3CH LOGIC when you play a Dolby
Surround Sound program and do not have rear speakers.
To turn on Dolby Pro Logic Surround or Dolby 3CH Logic, press PRO
LOGIC until PRO LOGIC appears on the display, then press SURROUND on
the remote control followed by CENTER MODE to select NORMAL, WIDE,
PHANTOM, or 3CH LOGIC. See “Sound Mode Adjustments (Remote Control Only)” on Page 23 for information about each of these options.
Virtual Dolby Surround (Dolby Virtual/SRS)
Note: The tone controls do not work
when you select VIRTUAL mode.
Virtual lets you enjoy programs encoded with Dolby Surround while
using only two front speakers. SRS creates a surround sound environment from a material recorded in stereo. Select SRS 1 for the source
that has broad frequency range such as classical or live music. Use SRS
2 for pop and jazz recording for smaller audio session atmosphere.
To turn on Virtual Dolby Surround, press VIRTUAL/SRS (VIRTUAL on the
remote control) until the desired option — VIRTUAL, SRS1, or SRS2 —
appears. Press VIRTUAL/SRS (VIRTUAL on the remote control) to turn off this
feature.
DSP Effect
You can choose one of five DSP effects — HALL, JAZZ, DANCE, THEATER 1, THEATER 2, or DIALOG. Hall simulates a large concert hall,
best suited for classical music. Jazz provides the acoustic effects generally heard in jazz clubs. Dance gives the effect of a discotheque. Both
theater modes provide the effect of a movie theater. THEATER 1 sounds
like a large movie theater. THEATER 2 seems like a smaller theater. Try
each setting to find the best effect for your programs. DIALOG enhances
the frequencies of human voice, so you can hear the dialogs more clearly. To turn on a DSP effect, press DSP MODE until the desired option appears on the display. Press DSP MODE to turn off the DSP mode. DSP OFF
appears on the display.
22
Using Advanced Sound Options
5-D Theater
5-D Theater provides clearer and more dynamic sound effects by outputting audio signals through the rear channel to simulate the stereo
sound, compared with a standard surround system which provides only
monaural signals to the rear speakers. Press 5-D THEATER to turn this
feature on/off.
DVD 5.1-Channel Input
Together with a multi-channel decoder or DVD player with 5.1-channel
output, you can feed sound to all five speaker channels. The front L/R,
surround L/R, center speaker channels, and the subwoofer have independent signals for enhanced rich sound. The subwoofer channel contains bass sound only and the frequency range is smaller than the other
speaker channels, so it is called 5.1-channel system.
Note: This feature is active only when you select DVD/TV function.
Press DVD/TV on the front panel to select the function, then press DVD/TV
again. Each time you press the button, the mode alternates between
normal and 5.1CH operations.
To use this feature using the remote control, press
then press 5.1CH.

Center Mode Setting
Note: If you do not use a center speaker,
the monaural signals are only reproduced if you select PHANTOM.
The center mode setting affects the center channel’s bass signals. It
operates only when you select the Dolby Pro Logic Surround or Dolby
3CH Logic mode. On the remote control, press SURROUND then CENTER
MODE. Each time you press CENTER MODE, the setting changes: NORMAL,
WIDE, PHANTOM, or 3CH LOGIC.
NORMAL — For a small center speaker. The front left and right speakers
play the center-channel bass sounds.
WIDE — For a medium or large center speaker. The center speaker
plays the center-channel bass sounds.
PHANTOM — For no center speaker. All center-channel sound comes
from the front left and right speakers.
3CH LOGIC — For no rear speakers. The rear channel’s sound is sent to
the front left and right speakers.

Care and Maintenance
Your Optimus STAV-3780 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 and its remote control 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.
35
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.
