1. Recessed Front Panel - Prevents switches and controls
from accidentally being adjusted or broken.
2. Power Switch - Turns the amplifier ON and OFF
3. Power LEDs - Verifies that the amplifier channel is ON
4. Status LEDs - Displays the status of the amplifier. The LEDs
are as follows: SIGNAL indicates if signal is present; CLIP
illuminates if the amplifier is being overdriven; PROTECT
illuminates if the amplifier is experiencing a “short” in the
speaker array; THERMAL illuminates if the amplifier has
shut down due an overheating condition.
5. Female XLR & 1/4" TRS Input Jacks - Feeds input signal to
the amplifier using industry standard male XLR or 1/4" TRS
(tip/ring/sleeve) plugs.
6. Male XLR Daisy Chain Jacks - Enables the connection of
multiple amplifiers. The signal derived from the input
signal is directly passed through (daisy chained) to these
output jacks.
7. Stereo/Mono Switch - This dual purpose switch is used to
select the operating mode of the amplifier. In Stereo mode
the amplifier can be configured for standard 2-channel
stereo operation. In Mono mode the amplifier can be con-
figured for Standard Bridge mono, 70V mono or 100V
mono operation. Turn amplifier off before operating this
switch.
8. Level Controls - Adjusts the gain of the amplifier.
9. Load Switch - Selects the speaker impedance or transformer
voltage that will be connected the output binding posts. In
Standard Mode the amplifier can drive 2
Ω
, 4
Ω
or 8
Ω
speaker loads. In Constant Voltage Mode the amplifier can
drive an array of speakers using 70V or 100V transformers.
10. Output Binding Posts - Connects the speaker array to the
amplifier. These jacks allow bare wire, spade lugs or dual
banana plugs to be connected to the amplifier.
11. Internal Fans - internal fans keep the amplifier circuitry
cool. Allow a minimum of 3" clearance on the front and
back of the amplifier vents for adequate ventilation.
12. Chassis/Float ground switch - Isolates Audio Ground and
helps eliminate noise in the signal chain. With the switch
in “Chassis” position, the audio ground is connected to
chassis ground. In the “Float” position, the audio ground
is isolated (floating) from the chassis. The chassis is per-
manently connected to earth (safety) ground.
13. Mains Power Fuse - Protects the “mains” electrical cir-
cuit in case abnormal current draw from the amplifier is
experienced.
14. Mains Power Connector - Connects AC Voltage to the
amplifier. The power connector is safety approved IEC
type 320. The earth (safety) ground pin of the power
connector is permanently connected to the chassis. This
connection is capable of shunting in excess of 30A of
fault current.
15. Biamp/Stereo Switch - This dual purpose switch selects
either standard 2-channel stereo mode or 1-channel in,
2 channels out Biamp mode. Turn amplifier off before
operating this switch.
16. Removable Rear Panel - 8 screws can be removed to ser-
vice fans and internal components without unracking the
amplifier.
