Audison AV5.1K AV 5.1k HD is the first Car Audio amplifiers featuring digital inputs only, providing the ability to connect directly to the digital outputs of a digital signal processor (DSP). Through this connection, made via the Audison AD Link available on the Audison processors (bit One HD, bit One, bit Ten D), a Full DA HD audio chain can be created. Thanks to this chain, the high resolution (96kHz/24 bit) digital audio signal coming from the head unit, via the processor, can be obtained up to just the Digital/Analog converter of the amplifier’s audio chain, ensuring maximum reduction of any signal deterioration. The Audison AC Link can also be connected to control the amplifier as well as the AC Link and AD Link outputs, to expand the audio system with other Audison Voce amplifiers. These features make AV 5.1k HD the most advanced amplifier available in the market, perfect to appreciate the quality of Hi-Res audio files. Hi-Res Audio According to the definition of HiRes audio provided by JAS (Japan Audio Society – jas-audio.or.jp), AV5.1k HD exceeds the 24 bit / 96 kHz digital to analog conversion processing requirement, providing an astonishing 24 bit / 192 kHz Full DA HD Pure digital signal transfer with a resolution up to 24 bit / 96 kHz Output Power (RMS) A B C Ch @ 14.4 VDC, THD 1%: 5 Ch: 75 W x 2 (4Ω) 140 W x 2 (4Ω) 600 W x 1 (4Ω) 5 Ch: 75 W x 2 (4Ω) 140 W x 2 (4Ω) 1000 W x 1 (2Ω) 5 Ch: 75 W x 2 (4Ω) 250 W x 2 (2Ω) 1000 W x 1 (2Ω) Power Supply Power supply voltage: 11 ÷ 15 VDC Idling current: 3 A Idling current when off: 0.02 mA Consumption @ 14.4 VDC (Max Musical Power): 110 A Amplifier Stage Distortion – THD (1k Hz @ 4Ω ) A, B Ch: 0.05 % Distortion – THD (100 Hz @ 4Ω), C (sub) Ch: 0.3 % Bandwidth (-3 dB) A, B Ch: 4 ÷ 60k Hz Bandwidth (-3 dB) C (sub) Ch: 7 ÷ 350 Hz S/N ratio (A weighted @ 1V) A, B Ch: 100 dB S/N ratio (A weighted @ 1V) C (sub) Ch: 87 dB Damping factor (1k Hz @ 4Ω) A, B Ch: 100 Damping factor (100 Hz @ 4Ω) C (sub) Ch: 80 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 A / B / C Ch: 4Ω / 2Ω / 2Ω NOMINAL POWER (RMS) A B C Ch @ 12 VDC, THD 0,3%, 4Ω: 50 W x 2 120 W x 2 500 W x 1 CEA Specifications Output power @ 4Ω, 1% THD N, 14.4 V: 75 W x 2 140 W x 2 600 W x 1 SN ratio (ref. 1W output): 75 W Channels: 80 dBA 140 W Channels: 80 dBA 600 W Channels: 78 dBA Signals Inputs / Filters Inputs: Pre IN / Speakers IN Outputs: Pre OUT Full Range A Ch Filters (Full / Hi-Pass): 50 ÷ 5k Hz (2 range) @ 12 dB/Oct.
