Operating Modes (Configurable via Avia Audio Tool software) Mono: Each channel is configurable to operate independently from all other channels; Stereo: Adjacent channels (1&2, 3&4, 5&6, 7&8) are configurable to operate as a stereo pair with linked control settings;
Bridged: Adjacent channels (1&2, 3&4, 5&6, 7&8) are configurable to operate as an 8 Ohm bridged mono output; 4/8Ω Mode: Each channel is configurable for 4/8 Ohm “Lo-Z” output; 70V Mode (AMP-8075 only): Each channel is configurable for 70 Volt “Hi-Z” o
100V Mode (AMPI-8075 only): Each channel is configurable for 100 Volt “Hi-Z” output
Output Power, AMP-8075 75 Watts per channel @ 4-8 Ohms or 70 Volts nominal; 150 Watts per bridged pair of channels @ 8 Ohms
Output Power, AMPI-8075 75 Watts per channel @ 4-8 Ohms or 100 Volts nominal; 150 Watts per bridged pair of channels @ 8 Ohms

Crosstalk >70 dB
Input Sensitivity 1.23 Vrms, +4 dBu (balanced) for full rated output power
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;
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 ˜2 seconds
