About Lab Gruppen LM 44

Powerful, Compact and Fully Featured Standalone Digital Audio System Processing with Peerless Credentials
The LM 44 provides a four input/four output analog configuration that is suited for a variety of system signal processing and routing applications. The LM 44 also provides 8 x 8 AES3 digital I/O and 4 x 8 Dante networked I/O, all with comprehensive signal routing to provide Dante break-in / break-out and failover functionality. Two LM 44 units may be stacked and linked to function as an 8 x 8 processor.

LM 44 provides the ultimate combination of input/output signal flexibility and fail-safe operation. Audio inputs are accepted via the Dante network as well as on connectors for AES3 digital and analog.

Simple programming in LAKE Controller allows multiple, user-configured automatic switching scenarios. For example, signals may be distributed over the Dante network, with an AES3 input source failing over to analog - and with the result automatically cascading to all Dante receivers. In addition, the LM Series' dual-redundant network topology enables seamless switching in case of a problem on one Ethernet link.

LM 44 provides a total of eight input routers which can be independently configured with up to four input fail-over priority settings. And the output of any of these input routers can be patched directly to any analog, AES3 or Dante output - without using any of the valuable Module processing channels.

LAKE Processing
The advanced technology of LAKE Processing provides unparalleled power to shape and optimize sound in a variety of environments, regardless of loudspeaker system, the venue size or acoustics, or the program material.
