1. Recessed Front Panel - Prevents switches and controls from acci- dentally 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; THER- MAL illuminates if the amplifier has shut down due an overheat- ing 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 multi- ple 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 amplifi- er can be configured for standard 2-channel stereo operation. In Mono mode the amplifier can be configured 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 volt- age that will be connected the output binding posts. In Standard Mode the amplifier can drive 2Ω, 4Ω or 8Ω speaker loads. In Constant Voltage Mode the amplifier can drive an array of speakers using 70V or 100V transformers.

10.Output Speakon Connections - Connects the speaker array to the amplifier. Individual Speakon connectors can be used for stereo connections, or, a single 4-wire Speakon connector can be used for stereo, BIAMP or mono mode speaker connections.

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 from Chassis Ground (Chassis Ground is permanently connected to Earth Ground through the third pin of the power cord). With the switch in the "Chassis" position, the Audio Ground is connect- ed to Chassis Ground. In the "Float" position, Audio Ground is isolated ("floated") from Chassis Ground, and must be connect- ed to Earth Ground by other means.

!CAUTION: Do not attempt to "float" Audio Ground from Chassis Ground unless you are absolutely certain there is some other common ground between the amplifier and the source equipment. Without this common ground, oscillations and severe damage may occur.

13.Mains Power Fuse - Protects the “mains” electrical circuit in case abnormal current draw from the amplifier is experienced.

14.Mains Power Connector - Connects AC Voltage to the amplifi- er. The power connector is safety approved IEC type 320. The earth (safety) ground pin of the power connector is permanent- ly connected to the chassis. This connection is capable of shunt- ing 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 service fans and internal components without unracking the amplifier.
