LM 26 and LM 44
Digital audio loudspeaker and system processors
The LM 26 provides a two input/six output analog
configuration that is ideally suited for multi-way
loudspeaker crossover, delay and EQ functions.
The LM 26 also provides 4 × 8 AES3 digital I/O and
4 × 8 Dante networked I/O, all with comprehensive
signal routing to provide Dante break-in / break-out
and failover functionality. Two LM 26 units may be
stacked and linked to function seamlessly as a single
4 × 12 processor.
LM 26 applications include:
• Crossover, delay and EQ for multi-way
loudspeaker systems
• Line driver and system EQ for self-powered
loudspeaker systems
• Dante break-in/break-out
• Transmission system to and from FOH and stage

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 × 8 AES3 digital I/O and
4 × 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 seamlessly as a single
8 × 8 processor.
LM 44 applications include:
• Mix-matrix and system EQ between FOH console
and loudspeaker system
• Line driver and system EQ for self-powered
loudspeaker systems
• Inserted EQ for monitor systems
• Dante break-in/break-out
• Transmission system to and from FOH and stage

Precision control at your fingertips
Lake Controller software suite
The Lake Controller and associated applications,
including Firmware Update and Preset Manger
Utilities, form a powerful suite of software enabling
detailed control and management of Lake processor
networks. The Lake Controller enables Windows
PC-based adjustment of all Lake Processing parameters,
including gain, delay, limiters, EQ, crossovers and
all I/O configuration and routing. Using a wireless
touch-screen Tablet PC, the Lake Controller can be
used to group processors together for simultaneous
control from any location in the venue. The included
Lake Analyzer Bridge provides a real-time interface
with Smaart Live and Live Capture Light/Pro, providing
direct audio analysis and measurement feedback within
the Lake Controller.

One controller for all, with iPad option
The LM Series integrates into the Lake Controller
software alongside PLM Series devices, Dolby Lake
Processors, and all other legacy Lake devices. New
Lake Controller functionality provides LM Series-specific
routing features, GPIO configuration and combined PLM
and LM Series global power control and event log. In
addition, Lake Controller functionality is now available
on the iPad using a VNC remote desktop solution.
