Nonuse PeriodsUnplug the receivers power cordwhen you will not use it for extended periods.

Outdoor Antenna GroundingIf an outside antennaor cable system is connected to the receiver, groundthe antenna or cable system so as to provide someprotection against voltage surges and built-up staticcharges. Article 810 of the National Electrical Code,ANSI/NFPA 80, provides information about propergrounding of the mast and supporting structure,grounding of the lead-in wire to an antenna dischargeunit, size of grounding conductors, location of antenna-discharge unit, connection to grounding electrodes,and requirements for the grounding electrode. See theexample below.

Preparing Your Receiver

Positioning Speakers Where you place your speakers (not supplied) can make a noticeabledifference in your s ystems s oun d. The guidelines in th is section will

help you ch oose the best locations. After you u se your receiver for a

while, you m ight wan t to try different locations for your sp eakers .

Bass response depen ds largely on speaker locat ion. For s t rong bass ,

place the sp eakers in the corn ers of the room. If you want even str onger

bas s, place the s peak ers directly on th e floor. If the b ass is too stron g,

move the sp eakers sl ightly away from th e corners of the room , or raise

them 6 to 18 inch es off the floor. You ca n bu y speaker sta nd s at your

local RadioSha ck store.

The dis tan ce between the speakers s hould be about the sa me as th e

distance between the normal l istening point and the point halfway

between th e spea kers. If you place the sp eakers too close together, you

redu ce the stereo sepa ration. If you place them too far ap art , you redu ce

the ba ss effect and create a hole in the middle of the sound.

Most speaker s ha ve a tweeter dispersion an gle of abou t 60 degrees.

Ideally, your l istening posit ion s hou ld be just ins ide the overlap a rea of

the tweeter dispers ion. You ca n a ngle the spea kers toward you for better

stereo effect.

To posi t ion your spea kers for su rround soun d, p lace the f ront s peakers

at the front of your l istening area, and place the (rear) surround speak-

ers b ehind or to th e sides of the l istening point (see Using Advan ced

Soun d Options on Page 22). Place the cen ter spea ker ab ove, below, or

behind the TV. If you place i t beside th e TV, the picture ma y not coin-

cide with th e soun d.

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

Connecting Speakers

Preparing the Speaker Wires

Speak er wire consists of two condu ctors (ind ividua l wires) encas ed in

insu lation a nd is u su ally 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 p roperly conn ect the sp eakers to you r receiver.

Follow these steps to prepare the speaker wires.

1 . Cu t t he speaker wires t o t he necessary lengt h .

2 . Separa t e t he wires abou t 4 inches on each end .

3 . Using a wire s t r ipper , careful ly s t r ip about 3/4 inch of insu lation

from the end of each conductor.

4 . Twist the end of each conductor to secure an y loose wire s t rands .

Setting the Impedance Selector Switch

Before proceeding to speaker connection, be sure to set the IMPEDANCE

SELECTOR switch to the ap propriate posit ion. If you connect s peak ers

with 6- to 8-ohm impedance, set the switch to 6~LESS THAN 8 W position. If

you are u sing 8- to 16-ohm impedan ce, set it to 8~16 posit ion.

Follow these guidelines when you selectand connect speakers.

Only connect speakers that are ratedat between 6 and 16 Ohms.

Be sure you properly connect allspeakers.

Do not connect two pairs of speakersto a single set of terminals at thesame time.

Optimus and other high-quality speak-ers have color-coded speaker termi-nals (red for positive polarity and

black for negative polarity). Use thesecolor-coded terminals as a guide tohelp you properly connect the speak-ers to the receiver.

Use 16-gauge (or larger) speaker wirefor all speaker connections, and con-sider possible speaker locations be-fore you decide how much speakerwire you need.

Connecting the Antennas In many areas, the supplied indoor AM loop and FM antennas providesa tisfactory reception.

AM Antennas

Ass emble the su pplied AM anten na s ba se by swinging the ba se in the

direction of the arr ow an d insert ing the ant enn as bottom tab s into the

bas es s lot . If the r eceiver is in a ra ck or on a sh elf an d th ere is no room

for the AM loop anten na , us e two screws (not su pplied) to mou nt th e

base on the wall or another locat ion as shown.

At tach th e anten na wires to the AM LOOP ANTENNA an d (ground ) term i-

nals (upper two terminals).

Place the antenna on a flat surface and rotate i t for the best AM recep-

tion.

Notes:

Keep t he AM loop an t enna connect ed even when you use a no t herindoor anten na or an outdoor AM antenna .

Ensu re t ha t the an t enna does no t t ouch t he r ece iver or any ot her

meta l object .

Do not p lace t he an t enna n ear a CD p layer , a per sonal compu t er ,

or a TV set.

If the wire between your AM loop an tenna and receiver i s too

sh ort , you ca n a dd extra wire, available at your local RadioSha ck

store.

You can a lso us e an optional RadioSha ck sh ortwave an tenn a kit (Cat.

No. 278-758), which makes an excellent outdoor AM antenna. Connect
