A standalone DSP that covers all the bases: 8 output RCA channels, 6 RCA inputs, 8 high-level inputs, coax SPDIF input, optical TOSLINK input, 3.5mm jack AUX input, Bluetooth SBC input, digital remote control for volume, sub level, preset selection, input selection, mute trigger. The DSP supports the following on every output channel: High pass, low pass and band pass crossovers (Linkwitz Riley, Bessel and Butterworth) up to 48 dB/oct 31 band fully parametric EQ with +/-15 dB correction Time delay up to 25 ms for time alignment, selectable in ms, cm or inches, optional linking of multiple channel time delays Phase switching between 0 and 180 degrees Level correction from 0 to -40 dB, optional linking of multiple channel levels Various mixing modes for mixing more than one input channels into one output channel Internal pink noise generator to test each individual output channel Configuration software for Microsoft Windows: DOWNLOAD HERE Manufacturer provided specs: Power supply voltage: 9-15 VDC, max 5 sec down to 6 VDC Output signal THD @ 1kHz, 1V RMS: 70 Frequency response : 20Hz-22kHz Input sensitivity (high-level in): 5-20V RMS, 200 Ohm Input sensitivity (RCA in): 0.4V, 22kOhm Max output level RMS: 5V DSP resolution: 32 bit Processing power: 295MHz (1.2 billion MAC opertations/s) Sampling rate: 48 kHz Digital input up to 96 kHz sampling rate ADC and DAC: A/D BurrBrown, D/A BurrBrown SNR digital in: 105 dB (A-weighted) SNR analogue in: 100 dB (A-weighted) Inputs: 6xRCA analogue, 1x RCA SPDIF coax, 1x 3.5mm aux, 1x TOSLINK SPDIF, 8x high-level, Bluetooth SBC module Outputs: 8xRCA analogue Control connections: 1x USB 1.1/2.0, wired remote (DRC) 8 full setup presets Auto on via high level signal detect or remote input What's included: 1x DSP unit 5m USB A-B cable 1x Power supply wiring harness 1x High-level input harness 1x Instructions
