AV due - STEREO AMPLIFIER 2x450W AV due is a powerful stereo amplifier with the power supply section and final stage designed to work also in mono and tri-mode, ensure very high output current, with powers up to 900 W (RMS). AMP (Amplifier Management Processor) constantly checks the operating status system and communicates with the user through 4 different coloured LEDs, located on the top panel; ART (Automatic Remote Turn On-Off) allows automatic turn-on/off when a remote signal isn't available from the source. Power Supply - Power supply voltage: 11 ÷ 15 VDC Idling current: 1.7 A Idling current when off: 0.02 mA Consumption @ 14.4 VDC (Max Musical Power): 65 A Amplifier Stage - Distortion - THD (1kHz @ 4Ω): 0.04 % Bandwidth (-3 dB): 4 ÷ 60k Hz S/N ratio (A weighted @ 1V): 100 dBA Damping factor (1k Hz @ 4Ω): 120 Input sensitivity: 0.3 ÷ 5 V RMS Input impedance: 15k Ω Speaker-In sensitivity: 1.4 ÷ 24 V RMS Speaker-In impedance: 5k Ω Minimum load impedance: 2Ω
