bit One HD Virtuoso by Audison
The bit One HD Virtuoso is a 13-Channel DSP from Audison with 24 Bit/96 kHz floating-point DSP processing. It features 12 high-level inputs, 12 low-level inputs, and 2 digital inputs as Optical S/PDIF with up to 192 kHz/24 Bit. Pre-outs are available on Ch1–Ch13 in IIR mode and on Ch1–Ch9 in FIR mode; digital outputs are provided via AD Link 1 (Ch1–Ch8, IIR/FIR) and AD Link 2 (Ch9–Ch13 IIR, Ch9 in FIR). The Crossover supports full, high-pass, low-pass, and band-pass filters with Linkwitz, Butterworth, Bessel, and FIR characteristics up to 48 dB. Time alignment with distances from 1.4 to 756 cm, delay 0–22 ms, and step sizes of 0.04 ms/1.4 cm/15.24 mm. The bandwidth ranges from 10 Hz to 44 kHz, THD is at 0.004 % (1 kHz, 1 Vrms), and the S/N ratio reaches up to 110 dBA depending on the input. Input sensitivities: Pre In/Master 1.3–9 Vrms, Speaker In/Master 5–32 Vrms, AUX 0.7–5 Vrms; input impedances: Pre In 15 kΩ, Speaker In/AUX 5 Ω. Remote IN 4–15 VDC (1 mA) and Remote OUT 4–15 VDC (130 mA), connection via micro USB as well as AC Link/AD Link including DRC MP. Nominal voltage 11–15 VDC, idle current 0.75 A, Fuse 2 A.
