Digital Audio Processor (Digital Audio Matrix)

The 3.6SP/4.8SP uses advanced DSP technology, featuring a 24-bit, 48kHz delta-sigma A/D converter with 128x oversampling. Digital processing includes: gain, polarity conversion, parametric equalizer and shelving filters, time delay, crossover functions, compression, limiting, and signal routing. All processing is handled by a pair of high-performance 120MHz DSP processors. The D/A converter is a 24-bit delta-sigma converter with 128x oversampling. All inputs and outputs use balanced XLR interfaces to prevent RF interference. You can adjust gain, delay, or 6-band EQ (each band selectable as parametric or high/low shelving) for each input channel. Before setting crossover points, signals can be routed internally within the DSP, and signals from two or more input channels can be mixed and routed to output channels. On the output channels, you can use 4-band EQ (each band selectable as parametric or high/low shelving), delay, gain, polarity inversion, or limiter modules. Despite such powerful DSP processing capabilities, the unit is only 1U in height, and all audio interfaces use standard XLR connectors.The DSP360/DSP480 can store up to 30 presets. Preset files use a "snapshot" method to completely store all control data for all channels. The DSP360/DSP480 is a powerful and user-friendly processor. Whether for live performance or fixed installation, it provides precise audio processing capabilities and outstanding sound quality.◎ Occupies one rack space◎ DSP480: four input interfaces - eight output interfaces, inputs can be assigned to any output◎ DSP360: three input interfaces - six output interfaces, inputs can be assigned to any output◎ Slopes: 12 dB/Oct, 18 dB/Oct, 24 dB/Oct, and 48 dB/Oct / input delay 682 ms, output delay 21 ms◎ Uses Linkwitz-Riley, Bessel, and Butterworth filters◎ Parametric EQ: full bandwidth, 1/64 to 4 octaves range◎ Each output is equipped with a limiter and an intuitive user interface◎ Programmable via front panel or RS232◎ 48 kHz sampling rate◎ Independent input/output indicators◎ Balanced XLR input and output speaker interfaces◎ Comes with dedicated PC control software◎ Frequency Response: 20Hz-20kHz, ±0.25dB◎ Distortion (THD + N): <0.01%◎ Dynamic range: >110 dB◎ Maximum delay: 682 ms on inputs, 682 ms on outputs◎ Output gain adjustmentGain: -40dB to +12dB ◎ Parametric equalizer: 6 bands per input, 4 bands per output ◎ Input graphic equalizer: No ◎ Crossover filters: 12, 18, 24, or 48dB per octave ◎ Limiter threshold: -20 to 20dBu ◎ Maximum output level: +20dBu ◎ Input impedance: 18kΩ ◎ Output impedance: 100Ω ◎ Power requirement: 90-240 VAC ◎ Dimensions (W×H×D, mm): 483×44.4×203 ◎ Net weight: approximately 4.05kg
