New from Lake Technology is the Lake Mesa Quad EQ, a 4x4 digital matrix processor designed for use in standalone or networked concert sound, recording, mastering, and broadcast studio applications. Incorporating the same DSP-based equalization, delay, and dynamics processing tools found in the Lake Contour digital speaker processor, including the asymmetrical Mesa Filter function, the Lake Mesa Quad EQ is also supported by the Lake Controller software in its latest release, Version 3.0.
In addition to shelving and parametric filters, all four discrete channels of the Lake Mesa Quad EQ feature Lake's EQ Overlay processing, which may be configured to provide both Lake Mesa EQ Parametric Overlays and Ideal Graphic EQ Overlays according to the demands of the situation. A virtually unlimited number of EQ filters may be implemented.
The asymmetrical filtering of the Lake Mesa EQ Parametric Overlay provides the ability to separate the sides of a parametric section, change center frequencies, and adjust slopes independently. The raised cosine filters of the Ideal Graphic EQ Overlay sum flat to ensure that EQ controls precisely match response, offering superior selectivity compared to conventional filters with no interaction between adjacent bands.
Additional processing includes fully adjustable true RMS and soft-clamp limiting on individual channels. Each channel provides adjustment of A/D input headroom and input/output gain, and a delay of up to 2000 ms may also be introduced. Fast updating, high-resolution meters indicate true RMS and peak levels with peak hold.
The Lake Mesa Quad EQ offers four independent channels of galvanically isolated 24-bit, 96 kHz converters. As standard, each channel features an analogue input and output in addition to AES/EBU digital I/O. Inputs may be selected as digital or analog in pairs, with assignment of any combination of inputs to outputs handled by a 4x4 matrix. All eight outputs - four digital and four analog - are available simultaneously, allowing the unit to be used as a distributionmatrix if desired.
Using the Windows-based Lake Controller V3.0 software, which is now available for download from the Lake Contour website, users may enjoy full interoperability between Lake Contour and the new equalizer units on the same Ethernet network from a single interface. Entire system configurations may also be stored in the hardware of multiple Lake Contour and Lake Mesa Quad EQ processors for instant recall and comparison via the controller.
The Lake Mesa Quad EQ satisfies a variety of live and studio applications. For example, in situations where the loudspeaker system incorporates proprietary processing or self-powered loudspeakers, the Lake Mesa Quad EQ offers a more economical and extensible solution for system routing and processing. Multiple four-channel Lake Mesa Quad EQs may be combined to apply overall system equalization in multi-zone sound system setups or may be inserted into the monitor console outputs to provide precise equalization of onstage monitor speakers.
In the mastering studio, the unit's innovative raised cosine filters ensure that the integrity of the mix is maintained while allowing surgically precise manipulation of troublesome frequencies. When networked, two Lake Mesa Quad EQ units can provide the ultimate consistency throughout any multi-channel surround mastering project.
