Technology Overview
The LM 26 is a full-featured, 2-in / 6-out or 4-in / 4-out stand-alone
digital audio loudspeaker processor. Based on the highly acclaimed
Lake Processing technology, it provides seamless compatibility with
Lab.gruppen’s PLM
™
Series Powered Loudspeaker Management
™
systems as well as LM Series and the MY8-LAKE. The LM 26’s
easily programmable EQ and delay capabilities allow quick
reconfiguration for use as processor and line driver for self-powered
loudspeaker applications as well as for systems using separate power
amplifiers.
In step with the flexible Lake Processing technology implemented in
the PLM Series, the LM 26 accepts audio signals as analog, AES3
digital, or via Audinate’s advanced Dante digital audio network at
48 kHz and 96 kHz sampling rates. Automatic input priority switching
may be enabled, and the unit can function as both an input matrix
mixer and Dante break-in and break-out box.
Exclusive Lake Processing features incorporated in the LM 26 include
Raised Cosine Equalization; linear phase and classic crossovers;
and LimiterMax peak and RMS limiters. The Super Module capability
allows flexible grouping of processor channels across separate
hardware frames, including prior Lake products and PLM Series
units. All functions are controlled via wired or wireless networking
by the Windows
®
-based Lake Controller software application. A
universal power supply with detachable locking mains cable allows
worldwide use.
The LM 26 can be controlled or monitored via a 9-pin General
Purpose Input Output (GPIO) connection. External devices such
as alarm systems can trigger mute, power control or preset recall
functions; status and fault conditions can also be reported externally.
GPIO configuration is available via the front panel or Lake Controller.
