The PA870 Power Amplifier comes with eight Molex plugs already
installed, eight Phoenix™-type input connectors, and an AC power cord.
You should verify that these items were shipped with your amplifier
before you begin installation. If any parts are missing, contact Gentner’s
Technical Support at 1.800.283.5936 or 1.801.974.3760.
The PA870 is designed to use two rack spaces. Gentner recommends
that you install the PA870 in a standard 19” rack using four 10-32-
thread, 1/2˝-long screws to secure the amplifier’s cabinet to rails at
least 0.1˝ thick.
If you install the unit in an enclosed box or cabinet, ensure that
ventilation holes are provided so that air circulation can cool the
amplifier.
The front panel (see Figure 1, page 6) features an ON/OFF power
switch with a red “ON” LED. The other LED indicators show signal
presence/clip (one per channel) and bridge status. Each presence/clip
LED illuminates green to show signal presence and red when clipping
occurs. Each bridge status LED illuminates amber when the channel
pair it represents is bridged.
Turn the power switch ON only after the input and speaker connections
have been made and the gain controls have been set to minimum.
NOTE: Do not place the
amplifier near sources of
heat or expose it to
moisture, direct sunlight, excessive
dust, or vibration.
