Packaging & Delivery
Packaging Details:


1.Signal mixing, route, equalizer,etc
2.Handles 8 channels analog signal
3. DSP audio processor
4. RS1200 software

The DRD28A audio processor is a 1U device with multifunction of signal mixing, route, equalizer, etc, which simultaneously handles up to 8 channels analog signal with Line/Mic input.

With an internal 200 MIPS SHARC processor, it processes audio signals with 40-bit floating-point precision by using C-MARK RS1200 software.

Therefore DRD28A audio processor is capable of processing high quality audio signal. It has been widely applied in various occasions, including professional and entertainment applications.




  DSP processor with powerful computation function;
  Support the computation of 40-bit precision floating-point;
  Various built-in audio computation processing modules;
  8 analog inputs, 8 analog outputs;
  The gain for each Mic/Line input channel is from 0dB to +66dB;
  The 48V Phantom power supply of each channel can be controlled separately;
  8 different DSP processing modes, which can be optionally set through front panel;
  It can be configured in a PC based on Windows system, simple operation and easy to understand;
  Suitable for various applications.

  Delays: 50 ms, 100 ms, 200 ms, 500 ms, 1000 ms;
  Routers: 4×4, 8×8, 16×16;
  Mixers: 4×1, 4×2, 4×4, 8×1, 8×2,8×4,8×8 mixers
  Dynamics: Levelers, Compressors, Limiters, Noise Gates, Expanders, Clipper;
  Signal Generator: Sine, White Noise, Pink noise;
  Equalizers: Parametric Equalizers, Graphic Equalizers;
  Filters: High-pass, Low-pass, Low-pass shelving, High-pass shelving;
  Crossovers: 2-way, 3-way, 4-way;
  Level Meters: Level Meters of 1-channel, 2-channels, 8-channels.

Because c-mark DRD28A can provide users with high quality audio signals, it has a wide application, which can match the demand of sound reinforcement for most professional fields and social entertainment.
