The LM 44 is a powerful, full-featured digital audio processor based on the highly acclaimed Lake Processing technology. As its name suggests, LM 44 features 4-in / 4-out analog configuration, while also accommodating 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 iconic 'Mesa EQ' configuration, utilising 4 Mesa modules, each with an independent input mixer and output signal processing chain.
