The 4496-9 is the 4-Channel DAC configuration of the LavryBlue System.

The LavryBlue System is a modular design which allows the end user to populate the 1U 19" chassis with stereo modules that provide a variety of functions. Each unit may hold up to 4 channels of microphone preamplification, up to 8 channels of analog to digital conversion (ADC) or 8 channels of digital to analog conversion (DAC); or a combination of these functions. Each module has two channels and fills either 1 or 2 of the 4 available module slots in the chassis. Basic systems can be ordered with a minimum of one stereo module, allowing user installation of additional modules at a later date.


In addition to these modules, any chassis which includes any ADC channels will also include a LavryBlue M-Sync.

This multichannel clock synchronization module features ultra-stable crystal-referenced internal or external sync operation at 44.1, 48, 88.2, and 96 kHz. Wide lock mode is available for non-standard sample rates or vari-speed operation.

One M∙SYNC is required to provide clocking and synchronization for all M∙AD824 AD converter modules contained in the same 4496 chassis; This module also provides Word Clock out to synch other units and allow multiple racks of LavryBlue to function as one system.


  • Ideal for multi-channel systems.
  • Independent operation of the AD and DA converter clocking. Each M∙DA824 stereo DA converter module clocks from the incoming digital audio steam. This allows recording and playback at different sample rates with devices that are not synchronized; for example- record to a DAW at 96kHz while playing back a CD from a stand-alone CD player. Multiple M∙DA’s can also operate either independently for playback of unsynchronized sources at different sample rates, or sample-accurately in multi-channel systems.
  • Minimal systems can contain one AD, one DA, or one of each for stereo applications. Another popular configuration is one AD and two DA modules for “looping” a signal out of a DAW and monitoring the re-encoded signal; as in Mastering systems with analog and digital processing.
  • Microphone preamplifiers can be used independently of the converters, or with analog processing inserted between the MicPre and AD input.
  • Digital AES/XLR inputs and outputs are compatible with most SPDIF/RCA I/O using simple adapters or adapter cables.  
  • Field expandability allows the system to grow as your needs change or budget allows.


  • 4 channels of sonically transparent Lavry D-to-A conversion
  • CrystalLock™ mode option eliminates the effects of source jitter on conversion accuracy.

  • The 4496 Chassis is a standard 1U 19”rack unit.
  • Input Voltage-
    • “Universal” input accepts inputs of 90-264VAC, 47-63Hz, Internally fused 2.5A
  • Current Consumption @120VAC-
    • Steady-state: Typically less than 0.5A (Varies with configuration/number of modules).
    • Steady-state Maximum: 1A
  • Dimensions:
    • 19” wide x 11.5”deep x 1.75” high (Enclosure minus clearance for switches and connectors measures 10.5” deep)
  • Approximate Weight-
    • ~ 9 lbs (Varies with configuration/number of modules).


  • Dynamic Range (22Hz – 22KHz unweighted):
    • 110dB referenced to 0dBFS
  • Distortions:
    • 1kHz tone at -1dBFS: .002%FS
    • 1kHz tone at -20dBFS: .0013%FS
    • 1kHz tone at -60dBFS: .0006%FS
  • Sample rates:
    • 96kHz, 88.1kHz, 48kHz, 44.1kHz in CrystalLock™ or Narrow with a
      +/- 100ppm lock range  (+/- 150ppm typical)
      (Front panel lamps indicate sample frequency and “Lock”)
    • 42-100kHz Wide lock mode (varispeed)
  • Crystal lock accuracy    
    • .1ppm / 10 sec maximum
  • Channel separation        
    • -100dBFs at 1KHz
  • Flatness response           
    • +/- .05dB (10Hz -20KHz)
  • Phase linearity                 
    • 2 degrees (10Hz - 22 kHz)

    • Front panel switch selects “Pin 2 +” or “Pin 3 +”
  • Analog Outputs:             
    • Balanced XLR “+4dBu nominal level” (maximum level of 24dBu +/-. 25dB) or Unbalanced (Maximum level of 18dBu +/-. 25dB).  
    • Balanced /Unbalanced settings are configurable for Pin 2 or Pin 3 “Hot” operation via user-selectable jumpers. Individual analog output front panel level control adjustments (20 turn potentiometers for each channel) provide 0 to +24dBu range for balanced outputs, and –6dBu to +18dBu for unbalanced operation for a digital signal of “0dBFS” (full scale digital level).
  • Digital Input                       
    • AES/EBU Balanced XLR, 110 Ohm, transformer isolated. Compatible with coaxial SPDIF using appropriate adapter.
