PLACEMENT
Place the ZR-8630AV on a flat, level surface such as a table or shelf, with its weight equally distributed on each
of its four feet. Placing the weight of the amplifier on the rear or front panel for even an instant will result
in damage to the amplifier's connectors and controls.
Like any high-fidelity component, the ZR-8630AV will last much longer if it has adequate ventilation for proper
cooling. When you install the ZR-8630AV in a cabinet, either open the rear of the cabinet to admit fresh air for prop-
er cooling (see Figure 28), or install two small “boxer fans” to provide continuous airflow in and out of the cabinet
(see Figure 29). Place the ZR-8630AV so it has at least seven inches (18 centimeters) of free air space above it. If the
amplifier is on a carpeted surface, place a board under its feet. Do not block the ventilation holes on the top and
bottom of the ZR-8630AV.

INSTALLATION
Make sure that there is a minimum
of 7” (18 cm) of free air space above
the amplifier and 3” (7.6 cm) on
each side for pr oper ventilation.
Allow a minimum of 2” (5 cm) of
depth behind unit to accommodate
cables and connectors.

CONNECTING SPEAKER WIRE TO THE NILES NO-STRIP CONNECTOR
The ZR-8630AV features an award-winning, patented no-strip speaker-wire connector. Follow the steps below to
connect the speaker wires to the connector and the connector to the ZR-8630AV.
1. Separate the speaker wire so at least two inches (five centimeters) of each conductor is free.
2. Open the no-strip connector by applying pressure to the red and black levers until you hear an audible “click.”
3. Insert the negative (
–
) unstripped wire fully into the speaker-wire hole
next to the BLACK lever and the positive (+) unstripped wire into the
speaker-wire hole next to the RED lever. Squeeze the RED and BLACK
levers until you hear an audible “click,” indicating that the connector
has locked onto the wire. (See Figure 30-A.)
4. Insert the no-strip connector into the corresponding zoned speaker-
output socket on the rear panel of the ZR-8630AV. Push it down until
it locks in place. The connector fits the socket in only one position. If
the terminal does not insert completely, reverse the connector 180
degrees and re-insert. (See Figure 30-B.)

CONNECTIONS
If the cabinet rear is not open to fresh air or if you’re using
low-impedance loads, install two “boxer fans” to provide
continuous air flow into and out of the cabinet.
