The Weiss DS1-MK3 is an extremely versatile single band digital limiter/compressor with M/S mode and Parallel Compression facilities.

The Gambit DS-1 MK3 is a compressor / limiter / de-esser, supporting all the features needed in a mastering environment: 96kHz 40bit processing, simultaneous de-essing and limiting spiced with a host of signal processing capabilities.

Features:

  • full band crossover in frequency selective mode (ranging from 41 Hz to 17.7kHz)
  • upward expansion to re-introduce dynamics in previously compressed signals
  • a second completely independent dynamics section working as a final peaklimiter in both modes (frequency selective and full band compressor)
  • an additional gain control ahead of this peak limiter allows to further boost loudness
  • ""parallel compression"" mode (original and compressed signal mixed) for lowering compression artefacts

Add to this the standard features of the DS1 (MIDI controller and snapshot remote control, touch sensitive knobs, backlit LCD, non-volatile backup memory for up to 3 x 128 snapshots, 24bit I/O), and you have one of the most comprehensive full band and band selective dynamics tools available.

AES/EBU Channel Status Data
The DS1 allows to convert the incoming Channel Status Data as follows:

  • From Consumer to Professional
  • From Professional to Consumer
  • Transparent mode, i.e. Channel Status Data is fed forward to the output without any conversion (one exception, see below)

The following tables describe how the output Channel Status Data Bits are generated in the various conversion modes.

Output selected: Consumer format, Input: Consumer format:
All Bits fed forward (transparent), except for Byte 1:

  • Bits 0…6: 0000000 (category code general)
  • Bit 7: 1 (original)

Output selected: Consumer format, Input: Professional format:
Byte 0:

  • Bit 0: 0 (consumer)
  • Bit 1: 0 (audio)
  • Bit 2: 1 (copy allowed)
  • Bits 3, 4: Pre-emphasis according to input 
  • Bit 5: 0 (two channel mode)
  • Bits 6, 7: 00 (Mode 0)

Byte 1:
