8 Using Your Amplifier
ˆ
Using Your Amplifier
1. Start the input sound source.
2. Make sure LEFT and RIGHT on the front
of the amplifier are set to MIN .
3. Press POWER to turn on the amplifier.
4. One at a time, adjust LEFT and RIGHT to
the desired volume level.
Turn LEFT and RIGHT 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
LEFT and RIGHT so the
meter’s pointer does not continuously
swing to the extreme right.
5. When you finish, press POWER to turn
off the amplifier.
USING THE METERS/METER
RANGE
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.
METER RANGE 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
METER RANGE to
the out position to maintain a 0 dB gain for
the meter. Or, press
METER RANGE to the in
position to allow a 20 dB gain.
CLIP INDICATOR
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
LEFT and RIGHT , warning you of possi-
ble damage to the amplifier. If this happens,
reduce the output level of the connected
sound source or
LEFT and RIGHT until the in-
dicator flickers only at peak volume levels.
USING SPEAKER A/B
Press in SPEAKER A or SPEAKER B on the
front of the amplifier for the channel you want
to listen to. Or, press in
SPEAKER A and
SPEAKER B to listen to all connected speak-
ers.
Caution: If you connected 4 ohm speakers
to the amplifier, to avoid damage do not set
both
SPEAKER A and SPEAKER B to the in
position.
MONITORING THE SOUND
SOURCES
To monitor the sound sources directly from
the amplifier, connect a pair of mono or ste-
reo headphones with a
1 /
4
-inch (6.35-mm)
plug into the PHONES 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.
