Lake LM 44 expands LM Series

AUTHOR: Inavate

Lake Processing has released a standalone system processor, the LM 44. The digital audio processor is based on Lake Processing technology and builds on the LM 26.

LM 44 has a different input/output configuration to the LM 26 and provides four analogue inputs and four analogue outputs. The processor accommodates eight-in/eight-out AES3 and four-in/eigth-out Dante digital audio transport. The LM 44 uses Lake’s ‘Mesa EQ’ configuration, utilising four Mesa modules, each with an independent input mixer and output signal processing chain.

The LM 44 is suited for FOH applications, including as a mix-matrix and full system EQ.

With the 4 × 4 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 4 x 4 analog I/O configuration (or multiples of this) is required.

Additionally, LM 44 can be operated in Contour mode configuration (two contour modules) allowing for utilisation as a loudspeaker crossover processor. 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 signal types – Dante, AES and analog – are maintained simultaneously, with user-prioritised 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 unrivalled flexibility and ease of use for existing Lake users.
