ˆ Preparation  
To avoid sudden audio from the input  
sources, be sure all audio devices are  
turned off before you connect them to  
the amplifier.  
PRESETTING THE  
CONTROLS  
Warning:  
A sudden high output from the  
amplifier could damage your hearing or  
the speakers connected to the amplifi-  
er’s output.  
CHOOSING A LOCATION  
Choose a location with adequate venti-  
lation. Do not place the amplifier on thick  
carpeting or cushions (which can restrict  
the air flow) or near a heat source, such  
as a heat vent or radiator (which can  
cause the amplifier to overheat).  
To avoid accidentally overdriving a  
channel or prematurely amplifying an  
audio input, set all the amplifier’s front-  
panel controls to their lowest settings.  
ˆ Making Connections  
Be sure you connect all auxiliary equipment  
and speakers before connecting and turning on  
power.

ˆ Speakers  
Most speaker terminals are color-coded  
or have a mark that indicates the termi-  
nal’s polarity. Usually, terminals with  
positive polarity are red or have a plus  
symbol (+), and terminals with negative  
polarity are black or have a minus sym-  
bol (–). If the speaker terminals are un-  
marked, follow these steps to determine  
their polarity.  
SPEAKER PHASING  
Phasing is the direction the speaker  
cone moves with reference to the polari-  
ty of the connection wires. Proper phas-  
ing is important when you use more than  
one speaker in the same room or area.  
Out-of-phase speakers can lose up to  
one-half of their potential volume, and  
can have a significantly decreased bass  
effect.  
1. Remove about 1 inch of insulation  
from both ends of a short piece of  
wire (not supplied; available at your  
local RadioShack store). Then twist  
the exposed wire to secure all its  
strands.  
Speakers are in phase if all the speaker  
cones move in the same direction when  
an equal signal is applied. Phasing is  
correct if you observe the correct polari-  
ty (+ to + and – to –) when connecting  
the speakers.  
2. Connect one end of the wire to one  
of the speaker terminals.

ed in series, parallel, or series/parallel  
combined.  
Note:  
We recommend that you use  
speakers that are rated the same (for  
example, all 8-ohm speakers) for all se-  
ries or parallel connections.  
4. Touch the negative end of the bat-  
tery with the lose end of the wire  
attached to the other speaker termi-  
nal. Note the direction of the cone  
movement — inward or outward.  
• Speakers are connected in series  
when the first speaker’s positive ter-  
minal is connected to the next  
speaker’s negative terminal. Deter-  
mine the total impedance of speak-  
ers connected in series by adding  
up the individual impedances of all  
the connected speakers.  
5. If the speaker cone moves outward,  
the speaker terminal where you  
touched the positive end of the bat-  
tery is positive. Mark that terminal  
with a + and mark the other terminal  
with a –.  
For example, if you want to connect  
two 8-ohm speakers in series, add 8  
(the impedance of one speaker)  
plus 8 (the impedance of the other  
speaker) for a total speaker imped-  
ance of 16 ohms.  
If the speaker cone moves inward,  
the speaker terminal with the wire  
attached that touched the negative  
end of the battery is positive. Mark  
that terminal with a + and mark the  
other terminal with a –.  
• Speakers are connected in parallel  
when all their negative terminals are  
connected together and all their  
positive terminals are connected  
together. For speakers rated the  
same, find the total impedance of  
speakers connected in parallel by  
dividing the impedance of one  
speaker by the number of speakers.  
6. Remove the wire.  
Repeat Steps 2–6 for each speaker with  
unmarked terminals you plan to connect  
to the amplifier.  
DETERMINING TOTAL  
SPEAKER IMPEDANCE  
For example, if you want to connect  
two 8-ohm speakers in parallel,  
divide 8 (the impedance of one  
speaker) by 2 (the number of speak-  
ers) for a total speaker impedance  
of 4 ohms.  
Caution:  
A total speaker impedance  
that is higher than 16 ohms (Ω) or lower  
than 4 ohms can damage your amplifier  
or speakers. Be sure to make the proper  
connections.  
Before you connect speakers to the am-  
plifier, you must determine the total  
speaker impedance. In determining the  
total speaker impedance, you must first  
determine if your speakers are connect-

• If you connect more than two speak-  
ers using only series or only parallel  
connections, the total impedance  
might exceed the amplifier’s maxi-  
mum impedance (16 ohms) or fall  
below its minimum impedance (4  
ohms).  
You can connect one or more 4-, 8-, or  
16-ohm speakers, with or without trans-  
formers, between the amplifier’s output  
and the speakers’ input. To ensure  
equal volume from each speaker, all the  
connected speakers should have the  
same impedance rating.  
For example, if you connect four 8-  
ohm speakers:

terminal. Then connect the speaker’s  
positive (+) terminal to the amplifier’s  
terminal that matches the speaker’s im-  
pedance. For example, if you have an 8-  
ohm speaker, connect the speaker’s  
positive terminal to the amplifier’s 8-ohm  
terminal.  
–In parallel, the total impedance is 2  
ohms (8 ÷ 4 = 2). This falls below  
the minimum rating.  
You can arrive at a proper total  
impedance by combining series and  
parallel connections.  
CONNECTING SPEAKERS  
You need speakers and wire to com-  
plete the connections to your amplifier.  
Use 16-gauge wire or larger. For parallel  
connections or those involving more  
than two speakers, you also need wire  
connectors. All of these items are avail-  
able at your local RadioShack store.  
8
Speaker  
Two or More Speakers Without  
Transformers  
We recommend connections without  
transformers if the length of the connect-  
ing wires between the amplifier and the  
speakers is 50 feet or less.  
Remove about 1 inch of insulation from  
both ends of each wire. Then twist the  
exposed wire to secure all its strands.  
Connect the speaker wire to the amplifi-  
er by pressing down on the appropriate  
push terminal tab and inserting the end  
of the twisted wire into the terminal’s  
hole. Then release the tab to secure the  
wire.  
When making connections without  
transformers, all the speakers must  
have the same impedance rating to en-  
sure equal volume from each speaker.  
When there is more than one speaker in  
a sound system, you must determine the  
total impedance of the speakers before

speaker impedance (8 , in this  
example).  
Multiple Speakers with  
Transformers  
If you connect these speakers in paral-  
lel, the total impedance is 2 ohms (8 ÷ 4  
= 2). This falls below the minimum rat-  
ing.  
For complex multiple-speaker arrange-  
ments that require many speakers and  
long runs of connecting wire, we recom-  
mend you use a line transformer (not  
supplied), available at your local Ra-  
dioShack store.  
You can arrive at a proper total imped-  
ance by combining series and parallel  
connections.  
1. Group speakers into pairs.  
Note:  
When running lengths of wire  
longer than 50 feet, use wire that is  
heavier than 16 gauge.  
2. Connect each pair of speakers in  
series.  
There are several advantages to using  
transformers.  
For example, the total impedance of  
each pair of 8-ohm speakers is 16  
ohms (8 + 8 = 16).  
• You can connect speakers with dif-  
ferent impedances without causing  
differences in output between the  
speakers.  
3. Connect the pairs of speakers in  
parallel.  
4. To determine the total impedance of  
speakers connected in serial and  
parallel combined, divide the imped-  
ance of one pair of speakers by the  
number of pairs.  
• You can add or remove a speaker  
without having to recalculate the  
entire system’s impedance.  
You can reduce signal loss when  
you use speaker wire over 50 feet  
long.  
For example, if you want to connect  
four 8-ohm speakers in serial and  
parallel combined, divide 16 (the

ˆ Troubleshooting  
If you should run into difficulties, check  
the wiring of the system. Are there any  
short circuits in the speaker wiring?  
Have you provided adequate ventila-  
tion? Did you calculate speaker imped-  
ance correctly?  
Be sure microphones and connecting  
cables are not defective.  
Be sure you are using large enough  
speaker wire. You should always use  
16-gauge (or larger) wire. The longer the  
run of speaker wire, the heavier the  
gauge should be.  
If you have feedback problems, reposi-

If the amplifier does not work at all,  
check the fuse on the rear panel. If it is  
blown, replace it with one of the same  
size and type (see “Replacing Fuses” on  
Page 13).  
If you are operating the unit from a 12-  
volt DC power source, check the fuse in  
the supplied cable that connects to your  
vehicle’s 12-volt accessory socket. If the  
fuse is blown, replace it with a 4-amp  
125-volt fuse (see “Replacing Fuses” on

the back of the amplifier.)  
• Handle the amplifier gently and  
carefully. Don’t drop it.  
• Keep the amplifier away from dust  
and dirt.  
Follow these steps to replace the ampli-  
fier’s fuse.  
• Wipe the amplifier with a damp cloth  
occasionally to keep it looking new.  
1. Unplug the amplifier’s power cord.  
2. Using a flat-blade screwdriver, push  
and turn the fuse holder’s cap coun-  
terclockwise until the fuse holder  
pops out.  
Modifying or tampering with the amplifi-  
er’s internal components can cause a  
malfunction and invalidate its warranty.  
If your amplifier is not performing as it  
should, take it to your local RadioShack  
store for assistance.  
3. Remove the fuse holder and replace  
the fuse.  
4. Slide the fuse holder back in place  
then, using a flat-blade screwdriver,  
push and turn the fuse holder’s cap  
fully clockwise to secure it.  
REPLACING FUSES  
DC Cable  
The supplied cable is equipped with a  
4A 125V fuse (in line) to protect your  
amplifier from voltage surges and abnor-  
mal conditions. If the power indicator  
POWER  
does not light when you press  
,
check the fuse and, if necessary, re-  
place it with one of the same size and  
type.  
To replace the fuse, unscrew the tip of  
the cigarette-lighter plug. Then remove  
the old fuse and insert the new fuse. Se-  
cure the fuse by reattaching the plug’s  
tip.

stores and authorized RadioShack franchisees and dealers. EXCEPT AS PROVIDED HEREIN, Ra-  
dioShack 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 LIABILITY OR RE-  
SPONSIBILITY TO CUSTOMER OR ANY OTHER PERSON OR ENTITY WITH RESPECT TO ANY  
LIABILITY, LOSS OR DAMAGE CAUSED DIRECTLY OR INDIRECTLY BY USE OR PERFOR-  
MANCE OF THE PRODUCT OR ARISING OUT OF ANY BREACH OF THIS WARRANTY, IN-  
CLUDING, BUT NOT LIMITED TO, ANY DAMAGES RESULTING FROM INCONVENIENCE, LOSS  
OF TIME, DATA, PROPERTY, REVENUE, OR PROFIT OR ANY INDIRECT, SPECIAL, INCIDEN-  
TAL, OR CONSEQUENTIAL DAMAGES, EVEN IF RadioShack HAS BEEN ADVISED OF THE  
POSSIBILITY OF SUCH DAMAGES.  
Some states do not allow limitations on how long an implied warranty lasts or the exclusion or limita-  
tion of incidental 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.
