Introducing the Optimu s STA-3500

Your Optimus STA-3500 Digital Synthesized AM/FM Stereo Receiver is the per­fect control center for your audio/video system. It combines 100 watts-per-chan­nel of clean power with modern styling. It provides connections for two tape
decks, a turntable, a CD player, and one other audio source, such as audio from
a digital video disk (DVD) player. You can also connect up to two pairs of speak­ers (not provided) to your receiver.

Additional features include:

Digital-Synthesized Tuner

Automatic Tuning

30 Memory Locations

Tape Mo ni t ori ng

Built-In Protection Circuits

Remote Control

Precisely tunes to AM and FM stations.
Lets you search for the next available FM station.
Let you store and recall the frequencies for up to 30 radio stations.
Lets you listen to the actual recording as you record, if your tape deck has a

tape-monitoring feature. Also lets you listen to a tape playing in TAPE 2 while
TA PE 1 continues to record the program you selected.

Turn off the receiver to help prevent damage if a power surge or short circuit
occurs.

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.

Where you place your speakers 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
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.

onnecting 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 t wo pairs of speakers
to a single set of terminals (A or B) at
the same time. When you use two
pairs of speakers, conne ct one set to

Speakers A

and one set to

• 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 hel p 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 spe aker
wire you need.

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.

Connecting the A and B Speakers

Notes:

• 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.

• Fully insert the speaker wires to
ensure a good connection. Leave
extra wire at the back of the receiver
so you do not disconnect the wires
when you move the receiver.

Caution:

To prevent a short circuit, twist
the end of each conductor to be sure
that stray speaker wire strands do not
touch other speaker terminals or any
other receiver terminals.

Follow these steps to connect the right speaker to the receiver’s right

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

• If the wire between your AM loop antenna and receiver is too short, you
can add extra wire, available at your local RadioShack store.

The remote control uses two AA batteries (not included). Fo r the longest battery
life, we recommend alkaline batteries (such as RadioShack Cat. No. 23-557).

Cautions:

• Use only fresh batteries of the recom­mended size and type.

• Always remove old or weak batteries.
Batteries can leak chemicals that can
damage electronic circuits.

Note:

If the remote’s range is reduced,

replace the batteries immediately.

1. Press and remove the battery compartment cover.

2. Place two fresh AA batteries in the compartment as indicated by the
polarity symbols (+ and –) marked in the compartment.

3. Replace the battery compartment cover.

Your receiver has an AC power outlet that you can use to power an electronic
device, such as a turntable, cassette deck, VCR, and so on. This switched out­let turns on and off with the receiver and provides a maximum of 100 Watts
(0.8A max).

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.

Care and Maintenance

Y our STA-3500 Digital Synthesized AM/FM Stereo Receiver is an example of superior design and craftsmanship. The following
suggestions will help you care for the receiver so you can enjo y 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

CLEANER

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 m ight 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.

21

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.
