HP/LP/BP filters with 6–48 dB, phase shift, and delay correction from 0–20 ms in 0.01 ms steps are available. Up to 248 output EQs and 120 input EQs (PEQ/HSLF/LSLF) with ±12 dB in 0.5 dB steps are provided. Features include input mixer, subwoofer control, preset auto switch, and priority input mode. The optical S/PDIF input operates at 192 kHz and 24 Bit; the outputs deliver 8 x RCA with 6 V RMS. The input sensitivity is 1–6 V RMS at low level, 1–15 V RMS or 15–45 V RMS at high level. The signal-to-noise ratio is 106 dB (analog input, A-weighted) and 111 dB (digital input, A-weighted); the total harmonic distortion is < 0.0015 % and < 0.0009 %. Optional are a Bluetooth 5.0 extension and an LCD remote control. Dimensions: 105 x 40 x 185 mm.
