Your RadioShack High-Power Stereo Amplifi-
er produces a total of 110 watts to give add-
ed punch and power to your vehicle’s
existing auto sound system.
The amplifier produces up to 55 watts per
channel of clean, powerful sound at all audio
frequencies with minimum distortion. You
can connect your auto sound system’s low-
level or speaker-level outputs to this amplifi-
er.
Its features include:
14K Gold-Plated Noise-Isolated Low-Lev-
el Input Jacks — let you connect low-level
(preamplifier) signal inputs to match your
auto sound system’s output for the best
high-fidelity performance.
14K Gold-Plated Speaker Terminals — de-
signed for low impedance, high conductivity,
and minimum corrosion, to provide the high-
est signal transfer and lowest sound distor-
tion.
Input Level Control — lets you adjust the
level of the audio signals that enter the am-
plifier.
Automatic Power Switching — can auto-
matically turn the amplifier on or off when
you turn your auto sound system on or off
(depending on how you hook up the amplifi-
er).
Mute Turn On Circuit — eliminates the
thump you hear when you turn on some am-
plifiers.
Power Indicator — lights when power is
supplied to the amplifier.
Crossover Frequency Circuit — lets you
adjust the crossover frequency from 45
−
400
Hz. This lets you set up the amplifier so you
can connect a subwoofer.
Short Circuit Protection — distorts the am-
plifier’s sound if any output channel shorts,
alerting you to turn off the auto sound sys-
tem.
Auto-Off — protects the amplifier by tempo-
rarily shutting down if it gets too hot, an out-
put channel shorts, or it detects an input
overload. The amplifier restarts automatically
when it cools or the problem is corrected.
Protection Indicator — lights if the amplifier
shuts itself down.
THE FCC WANTS YOU TO
KNOW
Your amplifier might cause TV or radio inter-
ference even when it is operating properly.
To determine whether your amplifier is caus-
ing the interference, turn off your amplifier. If
the interference goes away, your amplifier is
causing it. Try to eliminate the interference
by:
• Moving your amplifier away from the
receiver
• Contacting your local RadioShack store
for help
