Abyssound ASP-1000 reference preamplifier works in Pure Class A operation an implements an Innovative BQVA (complementary Bi-Quartet design as the basis of operation). It uses no global feedback. There is no operational amplifier in signal path (transistor only).
Gain: 12dB or 18dB Frequency response: 3 Hz – 375 kHz (-3 dB) SNR: 107 dB Maximum output voltage: 12 Vrms Input impedance: (RCA) 30kOhm Input impedance: (XLR) 50kOhm Attenuation control: -6dB, -12dB, MUTE Ground switch: chassis / floating Output trigger 12V (for externall devices) Remote controller RCA Inputs: 4 + DIRECT input XLR Input: 1 RCA Output: 1 (doubled) XLR Output: 1 Main voltage: AC (50-60Hz) 220-230 V Power consumption: -active 30W -idle < 3.5W Dimensions and weight: 490mm x 90 mm x 340 mm (w x h x d) – 9.5 kg
Low noise volume control / Adjustable gain for each input / DIRECT input (for home theatre purpose) / Rhodium plated RCA inputs / Galvanic separation between analog and digital control circuits / Microprocessor – controlled smart protection system / Black or white colour finish / Front Panel made of high grade aircraft 20mm thick aluminium /
