Meyer Sound’s Galileo 616 is a 6-input/16-output, fully digital matrix processor that collects all of the facilities required to drive and align sound reinforcement systems employing multiple zones in a single box. The Galileo 616 will ship in the first quarter of 2005.
Housed in a 2U rackmount package, the Galileo 616 processor can be used as a stand-alone device operated directly from its front panel or with a laptop or other personal computer via Ethernet. An Ethernet connection presents a broad variety of control possibilities, such as the use of wireless laptop computers and tablets to control the device, enabling the user to walk around a venue while adjusting parameters on one or more Galileo 616 units. Full bi-directional communication ensures that the user is always able to instantly view current settings, whether operating it from the front panel or a laptop computer (PC or Mac).
The device’s six analog inputs are on balanced XLR connectors feeding A/D converters operating at 24-bit resolution and sample rates up to 96 kHz. Three of the inputs can be switched to operate as standard stereo AES/EBU digital audio inputs, also capable of operating at sample rates up to 96 kHz (using double-speed mode). Simultaneous use of analog and digital inputs is supported for up to a total of six input channels. Full matrix operation allows any combination of mixing and routing from inputs to outputs.
The 16 outputs allows the Galileo 616 to drive Meyer Sound’s self-powered loudspeakers to full output. Other features include the M Series array compensation functions of the LD-3 and a library of presets for configurations of both line array and point-source array products.
The Galileo 616 will provide direct interfacing to Meyer Sound’s SIM 3 audio analyzer system, such as the ability for the SIM 3 analyzer to treat the Galileo 616 as a switcher, automatically selecting source signals for the analyzer. Interfacing through existing or future digital audio networking schemes will also be possible.
Each input sports a 26 LED ladder meter and mute and select buttons/indicators, and each output has a bi-color level LED and mute and select buttons. Three high-resolution encoder knobs are used to make parameter adjustments, which are shown on the 128×64-pixel LCD.
A 1GHz vector DSP architecture employs a direct DMA audio path to maximize processing power and guarantee fixed low-latency performance, no matter how much processing is applied. High-quality algorithms at 32-bit floating-point resolution are used to implement a large assortment of processing, including up to two seconds of delay, CP-10 parametric and VX-4 program filters (a 4-band version of the VX-1) and LD-3 subwoofer crossover and atmospheric compensation filters.
