Lake Processing introduces the single-rackspace LM 44 stand-alone system processor, a full-featured digital audio processor based on Lake Processing technology, which builds on the LM 26 and marking another major step for the Lake brand under the stewardship of Sweden's Lab.gruppen.

Identical in many respects to the LM 26 Digital Audio Loudspeaker Processor, the LM 44 is distinguished primarily by a different input/output configuration. The LM 44 provides four analog input and four analog outputs, in contrast to the LM 26's two analog inputs and six analog outputs. In addition, the LM 44 accommodates 8-in/8-out AES3 and 4-in/8-out Dante digital audio transport. The LM 44 benefits from 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 LM 44 is suited for a wider number of 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, front-of-house to stage digital transmission, home theater applications, line driver for self-powered systems, and as a Dante break-in/break-out box.

With its flexible 4x4 input configuration, one or more LM 44 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 4x4 analog I/O configuration (or multiples of this) is required.

Additionally, LM 44 can be operated in Contour-mode configuration (two contour modules) as a loudspeaker crossover processor, much like the intended operation of LM 26. Inputs that are not routed to the processing modules (in each mode) may be passed through to the output router. As with the LM 26, all three types of signals--Dante, AES and analog--are maintained simultaneously, with user-prioritized automatic failover and dual redundancy, eliminating single point of failure.

The LM 44 integrates fully into all existing Lake system inventories, including PLM Series and LM 26, as well as with Dolby Lake Processors and all other legacy Lake devices, all controlled together via Lake Controller software, providing flexibility and ease of use for existing Lake users.

The LM 44 further offers full control via new version of Lake Controller software, 24-bit/96kHz AD/DA conversion, a 32-bit floating point internal data path, Raised Cosine Equalization, Gigabit dual redundant Dante by Audinate networking, and software configurable GPIO. It uses a universal power supply with lockable IEC.
