Connecting Your Amplifier
Connecting Your Amplifier
Connecting Input Sources
You can connect optional components, such as microphones, tuner, turntable,
audio mixer, preamplifier, or CD player to your amplifier to expand your system.
To prevent hum and other noise, use low-capacitance shielded cable (not
supplied, available at your local RadioShack store or at www.radioshack.com).
Notes:
• This amplifier is equipped with both stereo phono input and ¼-inch
(6.35 mm) jacks. The ¼-inch input jacks on the top are stereo while the
others are left and right mono.
• Before you make any connections, be sure the amplifier is turned off
and AC power cord is not plugged in.
Connecting Microphones
You can connect up to four high- or low-impedance microphones (not supplied)
to the microphone inputs on the back of the amplifier. Each input (MIC1, MIC2,
MIC3, and MIC4) has a balanced and unbalanced jack. You need a microphone
with a ¼-inch (6.35 mm) plug to connect to an unbalanced jack or a microphone
cord with a 3-pin XLR plug to connect to a balanced jack.
Notes:
• If your microphone cord is longer than 20 feet (6 meters), we
recommend that you connect it to a balanced jack to reduce signal
hum.
• If you connect a microphone to both balanced and unbalanced jacks
for MIC1, MIC2, MIC3, or MIC4, the microphone you connect to the
unbalanced jack has priority.
• If you connect a microphone to either MIC4 jack, set the MIC4/PHONO
switch to MIC4.
