AMPLIFIER PLACEMENT
RECOMMENDATIONS
• Install the amplifier indoors.
• Make sure there is an AC (mains) outlet nearby.
• To avoid interference, keep other wireless equipment 1 – 3 ft (0.3 – 0.9 m) away
from the amplifier.
• For optimum performance, place the amplifier in a well-ventilated area.
• Place the amplifier on a shelf, or mount it on a rack or wall.
• When mounting on a rack, make sure the rack mount arrow and four tabs are
facing the front of the rack (see page 55).
• When mounting multiple amplifiers on a rack, use a separate rack mount for
each amplifier.
• When mounting on a wall, make sure the wall mount arrow and four tabs are
facing up (see page 57).
CAUTIONS:
• Place the amplifier in an area where the maximum ambient temperature is less than
104°F (40°C).
• Keep the back side of the amplifier at least 3 – 6 in (7.62 – 15.24 cm) away from any
other surface. Do not block airflow from the back of the amplifier.
• Do NOT place the amplifier in a completely enclosed area. Doing so may result in
poor performance.

CONNECT SPEAKERS
Before connecting your speakers, place your speakers in their permanent location and
make sure the amplifier is unplugged from an AC (mains) power outlet.
Speaker wires consist of two insulated wires:
• The marked wire (stripes, ribbing, or color) connects to the positive (+) terminal.
• The plain wire connects to the negative (–) terminal.
1. Remove terminal block A from the SPEAKERS OUT port.
