Preparing Your Receiver  
Caution: Make all the necessary connections before you plug in or turn on the receiver.  
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 dif-  
ferent locations for your speakers.  
Positioning Speakers  
a
L
R
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.  
Halfway Point  
Between Speakers  
b
a = b  
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.  
Normal ListeningPoint
• 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 tweeter disper-  
sion. 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 par-  
ticularly 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 surround (rear) speakers behind  
or to the sides of the listening point (see “Using Advanced Sound Options” on  
Page 21). 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  
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 guidelines when you select  
and connect speakers.  
• Be sure you properly connect all  
speakers.  
Follow these steps to prepare the speaker wires.  
• 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.  
Wire Strands  
Conductor  
• Realistic, Optimus, and other high-  
quality speakers have color-coded  
speaker terminals (red for positive po-  
larity and black for negative polarity).  
Use these color-coded terminals as a  
guide to help you properly connect the  
speakers to the receiver.  
Wire Strands  
Conductor  
1. Cut the speaker wires to the necessary length.  
2. Separate the wires about 4 inches on each end.  
• Use 16-gauge (or larger) speaker wire  
for all speaker connections, and con-  
sider possible speaker locations be-  
fore you decide how much speaker  
wire you need.  
3
3. Using a wire stripper, carefully strip about /4 inch of insulation from the  
end of each conductor.  
4. Twist the end of each exposed wire to secure any loose strands.  
Setting the Impedance Selector Switch  
Before connecting speakers, check your speaker system’s impedance (see  
IMPED-  
your speaker system’s specifications). Normally it is 8W. If it is, leave the  
ANCE SELECTOR

1. Lift the receiver’s FRONT SPEAKERS A R (+) red lever and insert the ridged  
or color-coded conductor’s end into the small hole. Pull down the lever to  
secure the conductor.  
2. Lift the receiver’s FRONT SPEAKERS A R () black lever and insert the other  
conductor’s end into the small hole. Pull down the lever to secure the con-  
ductor.  
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 left FRONT SPEAK-  
ERS A terminals.  
Repeat this entire process to connect a second pair of speakers to the FRONT  
SPEAKERS B terminals.

Preparing Your Receiver  
Connecting Surround-Sound Speakers  
You can connect a pair of speakers to the receiver for surround-sound pro-  
grams. 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. Connect the  
center speaker to the CENTER SPEAKER terminals. Follow the steps in “Connect-  
ing 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 PRE OUT jack. Then connect the center channel speaker to the am-  
plifier.  
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 earth-  
quake, the bone-jarring percussion of a cannon, and more. To use the subwoof-  
er 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.

Connecting Video Sources  
If you connect two or more video sources, such as VCRs or laser disc players,  
to your receiver, you can use the receiver to select each video source. You can  
also use the receiver to easily record from the video sources to the source con-  
nected to VCR/TAPE 1.  
Note: If your VCR is monaural, use a Y-  
adapter (available at your local Ra-  
dioShack store) to connect the VCR’s  
audio output to both the L and R audio in-  
puts on the receiver.  
Connect phono cables from each video source’s audio outputs to the receiver’s  
VCR/TAPE 1 or LD/SAT IN (audio) jacks. Then connect phono cables from the re-  
ceiver’s VCR/TAPE 1 OUT (audio) jacks to the source’s audio input jacks.  
Connect video cables from each video source’s video outputs to the receiver’s  
VCR/TAPE 1 VIDEO IN or LD/SAT VIDEO IN jacks. Then connect video cables from the  
receiver’s VCR/TAPE 1 VIDEO OUT jack to the VCR’s video input.  
You can connect a third video source to the DVD/TV IN jacks. Connect the  
source’s video output to the receiver’s DVD/TV VIDEO IN jack, and the source’s au-  
dio outputs to the receiver’s DVD/TV IN (audio) jacks.  
The front panel VIDEO L AUDIO R jacks accept another audio/video device. These  
jacks are convenient for temporarily connecting another video source to the re-  
ceiver, such as a camcorder.  
Connecting a Video Monitor  
The monitor (or TV with baseband video input) you connect to the VIDEO OUT ter-  
minal can monitor any program you connect to the receiver’s VCR/TAPE 1, LD/SAT,  
or DVD/TV input jacks. Connect a video cable from the receiver’s VIDEO OUT TO  
MONITOR TV jack to the monitor’s video input.

If the receiver is in a rack or on a shelf and there is no room for the AM loop an-  
tenna, 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.

For better FM reception, you can also use a rabbit-ear TV antenna (for indoor  
use only). 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 antennas  
and antenna connection accessories.  
Note: For the best results, use 75-ohm  
coaxial cable to connect an outdoor  
antenna to the receiver.

Preparing Your Receiver  
For the best radio reception, use an outdoor antenna. Follow these steps to  
connect an outdoor FM antenna to the receiver using 75coaxial cable.  
Warning: To prevent injury, read and fol-  
low all cautions and warnings that  
accompany the outdoor antenna.  
Note: If your antenna has 300twin-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 11/2 inches of the outdoor antenna ca-  
ble’s outer insulation to expose the cable’s shielding.  
3. Fold back the outer insulation from the inner insulation.  
4. Remove about 1 inch of the inner insulation from around the center wire.

The remote control uses two AAA batteries (not included). For the longest bat-  
tery life, we recommend alkaline batteries (RadioShack Cat. No. 23-555).  
Installing the  
Remote Control’s Batteries  
1. Press and slide open the battery compartment cover.  
Cautions:  
• Use only fresh batteries of the recom-  
mended size and type.  
• Do not mix old and new batteries, dif-  
ferent types of batteries (standard,  
alkaline, or rechargeable), or re-  
chargeable batteries of different ca-  
pacities.  
• Always remove old or weak batteries.  
Batteries can leak chemicals that can  
damage electronic circuits.  
2. Place two fresh AA batteries in the compartment as indicated by the po-  
larity symbols (+ and –) marked in the compartment. Then replace the  
battery compartment cover.  
Note: If the remote’s range is reduced,  
replace the batteries.

Preparing Your Receiver  
Using the AC Power Outlet  
Your receiver has an AC power outlet that you can use to power another elec-  
tronic device, such as a turntable, cassette deck, VCR, or so on. This switched  
outlet turns on and off with the receiver and provides a maximum of 100 Watts.  
Caution: Do not connect appliances with  
high power consumption, such as a  
heater, iron, monitor, or TV, to this AC  
outlet. Doing so can cause a risk of over-  
heating and fire, and could damage the  
receiver.

Using Advanced Sound Options  
Your receiver has three special sound options: Dolby Pro Logic Surround, SFC  
Effects, and 5-D Theater. These special options enhance the sound you hear  
from 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, press DOLBY PRO LOGIC (or PRO LOGIC on  
the remote control). For Dolby 3CH Logic, repeatedly press the remote control’s  
CENTER MODE button until 3CHLOGICappears on the display. For SFC effects  
or 5 D Theater, press SFC MODE or 5-D THEATER until the desired option appears  
on the display.  
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 ap-  
propriate speakers, making you feel like you are really there. You can find hun-  
dreds 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 or-  
dinary 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 speak-  
ers.  
SFC Effects  
You can choose one of four SFC effectsHALL, JAZZ, STUDIO, or ARENA.  
Hall Effect simulates a large concert hall, best suited for classical music. Jazz  
Effect provides the acoustic effects generally heard in jazz clubs. Studio Effect  
gives the effect of listening in a recording studio. Arena Effect is ideal for sourc-  
es such as live performances. Try each setting and find the best effect for the  
programs you want to listen.  
5-D Theater  
5-D Theater provides clearer and more dynamic sound effects by outputting au-  
dio 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. Select 5-D PRO for sources encoded with Dolby Pro Logic, or  
select 5-DSURR.for normal stereo sources.  
Note: 5-D Theater Surround (5-D SURR.) produces stereo sound from the  
front speakers, enhanced with simulated surround sound from the rear speak-  
ers. The center channel does not operate.

If the remote control does not function due to strong static electricity, for exam-  
ple, insert a pointed object (such as a straightened paper clip or the tip of a pen)  
into the RESET hole on the top of the STAV-3690 remote control, then press and  
release it. This resets the remote control.  
Resetting the Remote  
Control  
You can use your STAV-3690’s remote control instead of ones for other audio/  
video components. To do this, you must first teach your STAV-3690’s remote  
the other device’s remote control commands.  
Training the Remote Control  
You can program the commands that appear on the remote control buttons. By  
changing the position of the AUDIO/VIDEO switch, you can program two com-  
mands to a single button.  
Notes:  
• You do not need to turn on the receiver or the other device.  
• You might not be able to teach commands from some remotes.  
 
25  
Using the Remote Control  
Follow these steps to train the STAV-3690’s remote control.  
1. Place both controls 1–2 inches apart with the windows facing each other.  
1–2''  
2. Select the AUDIO/VIDEO switch position. Set the switch to the position that  
best matches the functionto AUDIO for a CD player or tape deck or to  
VIDEO for a VCR or television.  
3. Insert a pointed object (such as a straightened paper clip or the tip of a  
pen) into the LEARN hole on the STAV-3690’s remote control, then press  
and release. The TRANSMIT/ LEARN indicator flashes.  
4. Within 1 minute, press the STAV-3690’s remote button you want to train.  
The TRANSMIT/LEARN indicator lights steadily.  
5. Within 1 minute, hold down the other device’s remote control button that  
you want the STAV-3690’s remote to learn. The TRANSMIT/ LEARN indi-  
cator flashes.  
If TRANSMIT/LEARN flashes twice, the signal might be too weak. Place  
the remote controls closer together and try again.  
If TRANSMIT/LEARN repeatedly flashes, the remote control’s memory is  
full. Programming errors can fill memory. For example, fluorescent light,  
direct sunlight, the two remote controls being too far apart, or a low bat-  
tery might cause this error. Correct the error and try again.  
6. Repeat Steps 4 and 5 to teach additional commands.  
7. To exit the teaching mode, press LEARN or wait 1 minute.  
To clear all learned commands from memory, press RECEIVER POWER, CD POW-  
ER, and TAPE/VCR POWER at the same time. The TRANSMIT/LEARN indicator flash-  
es four times.

Care and Maintenance  
Your STAV-3690 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. Tempera-  
ture 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 re-  
ceiver.  
Use only fresh batteries of the recommended size and type in the remote con-  
trol. Always remove old or weak batteries. They can leak chemicals that can de-  
stroy 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.  
 
28  
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.

VISED OF THE POSSIBILITY OF SUCH DAMAGES.  
Some states do not allow the limitations on how long an implied warranty lasts or the exclusion of in-  
cidental or consequential damages, so the above limitations or exclusions may not apply to you.  
In the event of a product defect during the warranty period, take the product and the RadioShack  
sales receipt as proof of purchase date to any RadioShack store. RadioShack will, at its option, un-  
less otherwise provided by law: (a) correct the defect by product repair without charge for parts and  
labor; (b) replace the product with one of the same or similar design; or (c) refund the purchase  
price. All replaced parts and products, and products on which a refund is made, become the prop-  
erty of RadioShack. New or reconditioned parts and products may be used in the performance of  
warranty service. Repaired or replaced parts and products are warranted for the remainder of the  
original warranty period. You will be charged for repair or replacement of the product made after the  
expiration of the warranty period.  
This warranty does not cover: (a) damage or failure caused by or attributable to acts of God, abuse,  
accident, misuse, improper or abnormal usage, failure to follow instructions, improper installation or  
maintenance, alteration, lightning or other incidence of excess voltage or current; (b) any repairs  
other than those provided by a RadioShack Authorized Service Facility; (c) consumables such as  
fuses or batteries; (d) cosmetic damage; (e) transportation, shipping or insurance costs; or (f) costs  
of product removal, installation, set-up service adjustment or reinstallation.  
This warranty gives you specific legal rights, and you may also have other rights which vary from  
state to state.
