Lake Processing has released the LM 44 system processor.

Lake LM44Based on Lake Processing technology, this is a standalone processor that is identical in many respects to the LM26 Digital Audio Loudspeaker Processor.

It is distinguished primarily by a different input/output configuration – four analogue input and four analogue outputs, in contrast to the LM 26’s 2-inputs/6-outputs. In addition, the LM44 accommodates 8-input/8-output AES3 and 4-in/8-out Dante digital audio transport. The LM44 also takes advantage of the latest implementation of Lake’s Mesa EQ configuration, using four Mesa modules, each with an independent input mixer and output signal processing chain.

With this configuration, the LM44 is well suited to a wider number of different FOH applications, including as a mix-matrix and full system EQ – sitting between a mixer and virtually any high-end performance loudspeaker system – switching between consoles on large events, inserted EQ for monitor systems, FOH to stage digital transmission, line driver for self-powered systems, and as a Dante break-in/break-out box.

With its 4 × 4 input configuration, one or more units can replace the now-discontinued Dolby Lake Processor in most applications. It also offers a cost-effective, scalable alternative to other larger and more expensive processors in situations when only a 4 x 4 analogue I/O configuration (or multiples of this) is required.

Additionally, it can be operated in Contour mode configuration (two contour modules) allowing its use as a loudspeaker crossover processor, much like the intended operation of LM26. Inputs that are not routed to the processing modules (in each mode) may be passed through to the output router. As with the LM26, all three signal types – Dante, AES and analogue – are maintained simultaneously, with user-prioritised automatic failover and dual redundancy, eliminating single point of failure.

The LM44 integrates fully into all existing Lake system inventories, including PLM Series and LM26, as well as with Dolby Lake Processors and all other legacy Lake devices – all controlled together via Lake Controller software.

Key features:

  • 1U-high chassis
  • Universal power supply with lockable IEC
  • Mesa Mode or Contour Mode operation
  • 4-input/4-output analogue with Iso-Float ground isolation on inputs
  • Raised Cosine Equalisation
  • Linear phase and Classic crossovers
  • LimiterMax peak and RMS limiters
  • Gigabit dual redundant Dante by Audinate networking
  • 96kHz, 24-bit A/D and D/A conversion
  • 32-bit floating-point internal data path
  • Full control via new version of Lake Controller software
  • Software configurable GPIO

LM44 was unveiled at Plasa 2011 and is available to ship immediately.
