Rack Mounting
The PM8500 is designed to fit standard 19-inch (48 cm) rack equipment, occupying 2 rack-units (RU) in height. Use four fasteners with
washers (not supplied) to mount the amplifier front panel rack ears to the equipment rack rails. Rack-mount tabs are also provided on
the rear of the chassis to secure the amplifier.
Ventilation
The PM8500 is designed to operate under wide conditions, with continuous operation at 40° C ambient temperature. However, to
ensure safe operation, the front panel, side and rear airflow vents should never be blocked. Air flows into the front of the unit and exits
the rear and side vents. The internal fans automatically increase speed when the amplifier is producing higher output power. Should the
unit exceed safe operating temperature, a gradual reduction of gain will automatically be applied for thermal protection. If the automatic
gain reduction does not reduce operating temperatures to safe conditions, the unit will mute all outputs and the red FAULT LED will
illuminate on the front panel.
AC Mains Outlet Requirements
The PM8500 features an efficient, universal switch-mode power supply with Power Factor Correction and can operate with AC Mains
line voltages from 100 to 240 volts at 50/60 Hz. With typical music program material, the PM8500 provides full rated power from a single
20-amp, 120V (common in USA) AC mains outlet, or single 16-amp, 230V (common in Europe) mains outlet.
High-power amplifiers draw large amounts of current from the AC mains. Use of extension cords to power the amplifier could introduce
significant impedance and a resulting voltage drop on the mains that may interfere with normal operation of the amplifier.
In countries like Japan where 100V AC mains are used, the following guidelines will be helpful to ensure optimal performance from the
PM8500:
• Ensure a minimum of 100V AC at the amplifier plug when the amplifier is idle.
• Use a dedicated mains circuit for each amplifier.
• Locate the amplifiers as close as possible to the mains outlet.
• If used, extension cords should be 14 AWG (2 mm
2
diameter) or larger.
• Extension cords should be less than 2 meters (6.6 ft) in length.
