DSP8
8-input, 8-output DSP processor
The DSP880 is an 8-input, 8-output DSP digital signal processor with software for a high-end all-in-one professional audio solution. The DSP processor features EQ, gain, crossover, limiter, delay, AFC, ANC, and more.
Characteristics
- The DSP adopts the SHARC DSP analog device with 40-bit floating-point processing. The main frequency is up to 500MHz, and the 512M memory can have a maximum of 16 fixed analog audio inputs, which are connected via a detachable balanced Phoenix connector. The analog input section can accept microphone or line-level signals with nominal levels of 0dBu, 10dBu, 20dBu, 30dBu, and 40dBu. +48VDC phantom power is available for each input. Preamplifier gain and phantom power are conveniently controlled by the DSP controller.
- A/D Specifications: Sampling Rate: 48 kHz THD+N: 105 dB Dynamic Range: 109 dB Audio Format: 24-bit MSB TDM , Sampling Rate: 48 kHz THD+N: -100 dB Dynamic Range (A-weighted): 112 dB Audio Format: 24-bit MSB TDM .
- The first stage of the analog output section is the DAC. The DSP uses an advanced 24-bit 256X sampling converter. Like AACs, a multi-bit architecture is used to achieve a wider dynamic range, but with the same excellent distortion characteristics as conventional single-digit digital-to-analog converters. Unity gain (0 dB) is set by the volume control, and the analog output section is corrected to +4 dBu with 14 dB of headroom. This means that a 0 dBFS digital signal is equivalent to an output signal of +18 dBu. If other signal levels are required, this can be easily achieved by changing the volume.
- Standard 1U chassis design. 8 balanced inputs, 8 line outputs. Supports phantom power.
- It has processing modules such as AFC (feedback suppression), AEC (echo cancellation), ANS (noise suppression), ANC (noise gain compensation), AGC (automatic gain), gain sharing, automatic threshold mixing, attenuator and other processing modules; Bus-type AEC, tail time: 512 ms, convergence speed: 60 dB / S, echo cancellation amplitude: 60 dB; Output per channel: parametric equalizer, delay, crossover, high and low pass filter, limiter.
- Built-in one-in-one USB sound card, supports music playback, recording and smooth video conferencing, supports matrix recording and mixing with full remote conference functions, and the input mixing level can be adjusted.
- Each channel has independent adaptive feedback suppression, automatically finds feedback points and automatically suppresses them. More features
