INSTALLATION
PLACEMENT
Place the ZR-4630 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-4630 will last much longer if it is given adequate ventilation for proper cooling. When installing the ZR-4630 in a cabinet, be sure that the cabinet’s rear is open to receive fresh air in order to provide proper cooling (see Figure 28). If the cabinet’s design does not accommodate an open rear, install two small “boxer fans” to provide continuous airflow into and out of the cabinet (see Figure 29). Place the ZR-4630 so it has at least seven inches of free air space above it. If the amplifier is located on a carpeted surface, place a board under the amplifier’s feet. Do not block the ventilation holes on the top and bottom of the ZR-4630.
Boxer Fan (55 CFM) directly centered 7” on top of the ZR-4630.
Boxer Fan (55 CFM) directly centered 2” behind the ZR-4630.
Figure 28
Make sure that there is a minimum of 7” of free air space above the amplifier and 3” on each side for proper ventilation.
Allow a minimum of 2” of depth behind unit to accommodate cables and connectors.
CAUTION! When using low- impedance speaker loads (less than 8 ohms Nominal) refer to Figure 29 for proper placement.
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.
CONNECTIONS
Speaker Wire Connections
CAUTION! All speaker wire connections must be made with the amplifier OFF.
Banana Plugs
There are many types of banana plugs available. Some are crimped onto the speaker wire and some are soldered.Niles offers banana plugs that have a quick-connect binding system for the speaker wire included within the banana plug itself. After the wire is attached, the banana plug is sim- ply inserted into the hole at the end of the amplifi- er's speaker binding post. Dual banana plugs will fit the binding posts.
Bare Wire
Unscrew the red or black plas-
tic knobs and insert the bare | |
wire through the hole in the | Figure 30 |
post. Tighten the knob until the |
wire is securely clamped. | |
