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, 4or 8speaker 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.
