.

3. Press 

 to turn on the amplifier.

4. One at a time, adjust 

 and

 to

the desired volume level.

Turn 

 and 

 clockwise to

increase or counterclockwise to
decrease the corresponding left and
right output power. To get the best per-
formance with the least sound distortion,
always adjust 

 and 

 so the

meter’s pointer does not continuously
swing to the extreme right. 

5. When you finish, press 

to turn

off the amplifier.

The position of the pointers on both of the
amplifier’s meters indicate the output power.
Built-in lamps light to make the meters easy
to see in dark areas.

 controls the sensitivity of both

meters. When output power is too strong, a
meter’s needle might continuously swing to
the extreme right and damage or reduce the
accuracy of the meter.

If the meter’s needle continuously swings to
the extreme right, press 

to

the out position to maintain a 0 dB gain for
the meter. Or, press 

 to the in

position to allow a 20 dB gain.

The CLIP indicator on the front of the amplifi-
er lights steadily when a sound source’s sig-

nal exceeds the output power level you set
using 

 and 

, warning you of possi-

ble damage to the amplifier. If this happens,
reduce the output level of the connected
sound source or 

 and 

 until the in-

dicator flickers only at peak volume levels.

Press in 

 or 

 on the

front of the amplifier for the channel you want
to listen to. Or, press in 

 and

 to listen to all connected speak-

ers.

Caution: If you connected 4 ohm speakers
to the amplifier, to avoid damage do not set
both 

 and

position.

To monitor the sound sources directly from
the amplifier, connect a pair of mono or ste-
reo headphones with a 

1

plug into the 

 jack on the front of the

amplifier. Using headphones lets you easily
check and adjust the sound source’s bal-
ance.

Note: Your local RadioShack store carries a
wide selection of headphones.
