| Operating Modes (Configurable via Avia Audio Tool software) |
Mono: Each channel is configurable to operate independently from all other channels; |
| Output Power |
600 Watts per channel @ 4-8 Ohms or 70/100 Volts nominal |
| Power Throttle | 600, 500, 400, 300, 250, 200, 150, 125, 100, 75, 50 Watts per channel |
| Frequency Response | 20 Hz to 20 kHz ±0.5 dB at 1 Watt, 4-8 Ohms; 200 Hz to 20 kHz ±0.5 dB at 1 Watt, 70/100 Volts |
| High Pass Filter | -3 dB @ 80 Hz, 12 dB per octave in 70V or 100V mode |

| Fault Protection | Over Current: Protects each channel individually against an excessive speaker load or shorted speaker line; DC Offset: Protects each channel and speaker line against DC voltages sensed at each output; Over Temperature: Protects the amplifier power supply and each channel against overheating due to poor ventilation or excessive temperature; Under Voltage: Protects the amplifier if the internal power supply voltage is below tolerance due to excessive output levels or insufficient line voltage; Note: All faults report to the control system, and indicate on the front panel and in the software tool. |
| Output Relays | Disconnects the speaker line at each output under fault conditions, and during startup and shutdown |
| Audio Ramp | Ramps each channel’s audio level up to its last used setting after the corresponding output relay has closed following startup or fault recovery; ramp time 130 milliseconds |
