DSA11 - audio processing OEM module

The DSA11 is a SHARC-based loudspeaker management OEM module, offering:

• serial port control
• open control protocol with provisions for multiple target addressing
• SPI control option
• analog audio I/O: 2 channels, +4dBu balanced
• digital audio I/O: 4 channels in I2S format
• slave booting option (via SPI)

The DSA11 measures 100 x 52 mm and sports two 0,1" spacing connectors for straightforward integration; it requires a 5V power supply for the digital section, plus a dual power supply for the analog front-end.

Audio algorithms

The DSA11 is provided with a standard firmware build (included in the base price), with the following functions:

• 48 kHz sample rate, 32-bit floating-point audio processing
• INPUT SECTION (two available):
• • noise gate
  • mute (with soft ramp)
  • 5-band parametric equalizer, with frequency, gain and Q control
  • static delay line, with a maximum delay time of 500 ms
  •  4-in, 4-out dynamic patch bay that allows routing of signals from analog and digital domains (in the standard firmware release, the user can route analog signals only)
• OUTPUT SECTION (two available):
• • compressor
  • 24-dB / oct Linkwitz-Riley crossover with adjustable frequency
  • 5-band parametric equalizer, with frequency, gain and Q control
  • static delay line, with a maximum delay time of 500 ms
  • phase reverse (with soft ramp) and output level (allows a maximum gain of 12 dB)
  • output limiter with lookahead buffer

Several additional algorithms can be provided within customized firmware builds.
