Preparing Your Receiver

Make all the necessary connections before you plug in or turn on the receiver.

Caution:

Wh ere you place you r speakers (n ot su pplied) can m ake a n oticeable

differen ce in you r system ’s sou n d. Th e gu idelin es in th is section will

h elp you ch oose th e best location s. After you u se you r receiver for a

wh ile, you m igh t wan t to try differen t location s for you r speakers.

Positioning Speakers

Bass respon se depen ds largely on speaker location . For stron g bass,

place th e speakers in th e corn ers of th e room . If you wan t even stron ger

bass, place th e speakers directly on th e floor. If th e bass is too stron g,

m ove th e speakers sligh tly away from th e corn ers of th e room , or raise

th em 6 to 18 in ch es off th e floor. You can bu y speaker stan ds at you r

local RadioSh ack store.

Midway Point

Between Speakers

a=b

Th e distan ce between th e speakers sh ou ld be abou t th e sam e as th e

distan ce between th e n orm al listen in g poin t an d th e poin t h alfway

between th e speakers. If you place th e speakers too close togeth er, you

redu ce th e stereo separation . If you place th em too far apart, you redu ce

th e bass effect an d create a hole in th e m iddle of th e sou n d.

Normal Listening Point

Most speakers h ave a tweeter dispersion an gle of abou t 60 degrees.

Ideally, you r listen in g position sh ou ld be ju st in side th e overlap area of

th e tweeter dispersion . You can an gle th e speakers toward you for better

stereo effect.

• 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.

To position you r speakers for su rrou n d sou n d, place th e fron t speakers

at th e fron t of you r listen in g area, an d place th e (rear) su rrou n d speak-

ers beh in d or to th e sides of th e listen in g poin t (see “Usin g Advan ced

Sou n d Option s” on Page 22). Place th e cen ter speaker above, below, or

beh in d th e TV. If you place it beside th e TV, th e pictu re m ay n ot coin -

cide with th e sou n d.

nals (red for positive polarity and

black for negative polarity). Use these

color-coded terminals as a guide to

help you properly connect the speak-

ers to the receiver.

This product is warranted by RadioShack against manufacturing defects in material and workman-

ship under normal use for two (2) years from the date of purchase from RadioShack company-

owned stores and authorized RadioShack franchisees and dealers. EXCEPT AS PROVIDED

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

INCLUDING THOSE OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE,

ARE LIMITED IN DURATION TO THE DURATION OF THE WRITTEN LIMITED WARRANTIES

CONTAINED HEREIN. EXCEPT AS PROVIDED HEREIN, RadioShack SHALL HAVE NO LIABIL-

ITY OR RESPONSIBILITY TO CUSTOMER OR ANY OTHER PERSON OR ENTITY WITH RE-

SPECT TO ANY LIABILITY, LOSS OR DAMAGE CAUSED DIRECTLY OR INDIRECTLY BY USE

OR PERFORMANCE OF THE PRODUCT OR ARISING OUT OF ANY BREACH OF THIS WAR-

RANTY, INCLUDING, BUT NOT LIMITED TO, ANY DAMAGES RESULTING FROM INCONVE-

NIENCE, LOSS OF TIME, DATA, PROPERTY, REVENUE, OR PROFIT OR ANY INDIRECT,

SPECIAL, INCIDENTAL, OR CONSEQUENTIAL DAMAGES, EVEN IF RadioShack HAS BEEN AD-

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.
