Meyer Sound Galileo Loudspeaker Management System

Meyer Sound’s self-powered loudspeakers have a new addition to speaker system management with the introduction of the Galileo 616.

Meyer Sound’s self-powered loudspeakers have a new addition to speaker system management with the introduction of the Galileo 616. I have used the Meyer LD-3 processor on numerous occasions, however the LD-3 has no internal delay or EQ capabilities. The Galileo takes processing to the next level with a comprehensive hardware/software system that provides all of the facilities necessary to drive and align Meyer Sound sound reinforcement speaker systems employing multiple zones.

The Score

Meyer Sound packed a lot of goodies into this powerful box – with software, too!

The system consists of the Galileo 616, a six-input/16-output, 2RU, fully digital matrix processor that uses Meyer Sound’s Compass control software for operation. The unit has a retail list price of $7,500. The Galileo 616 can be interfaced via its Ethernet connection for ease of use to a remote computer or wireless tablet running under either the Macintosh or Windows platform. It can also be controlled directly from its front panel for maximum flexibility.

The Galileo system includes array compensation for M Series line array products, presets for Meyer Sound systems of all sizes and types, and digital implementations of popular features developed over the years by Meyer Sound for its acclaimed analog processors (CP-10, VX-1, LD-3) and includes air absorption compensation.

The six analog inputs are terminated via balanced XLR connectors on the rear panel. The unit uses high quality A/D converters operating at 24-bit resolution and a 96 kHz sample rate. The inputs can be individually switched to operate as standard stereo AES/EBU digital audio inputs, accepting sample rates up to 96 kHz. Since all internal processing is performed at 96 kHz (32-bit vector floating point), any signals entering at a lower sample rate are upsampled using sample rate converters. The six input channels can be a combination of analog and digital inputs. With full matrix operation capabilities, the Galileo allows any combination of mixing and routing of inputs to outputs.

The 16 outputs use high-quality D/A converters and share the same line driving capabilities as those of Meyer Sound’s analog line driver products, up to +26 dBu permitting the Galileo 616 to drive Meyer Sound self-powered loudspeakers to full output even over long lines.

A substantial, 1 GHz vector DSP architecture employs a direct DMA audio path to maximize processing power and guarantee fixed low-latency performance. Internal processing in this unit includes up to two seconds of delay, CP-10 parametric and patent-pending TruShaping program filters, with subwoofer and DX 2 or 4 crossover and atmospheric correction filters. Even when applying all available processing to every channel, Galileo 616’s DSP engine retains substantial processing headroom.

In Use

I recently used the Galileo 616 at the Mann Music Center in Philadelphia with Tony Bennett and his quartet. The inside pavilion of this outdoor amphitheater seats 7,500 people. A Meyer Sound Milo self-powered line array was employed using a left/ right configuration of 10 boxes per side. Using the Galileo, the arrays were zoned with control of the top two boxes, then a zone for the next six, and a separate zone for the bottom two boxes of each array. The show was mixed using a Midas Heritage H-3000 console. The sound system was supplied by Masque Sound from New Jersey.

Upon inspection of the processor, I was impressed with its ability to directly interface to Meyer Sound’s SIM 3 audio analyzer system. It allows Galileo to act as a line switcher for the SIM 3 analyzer. Also, a locking AC connector on the rear is well designed, eliminating the chance of it accidentally being unplugged during a show. Trust me: I had that happen once during a show with an XTA processor and it was no fun.

Using a wireless tablet I found it easier to see and configure when using the front panel controls, which seemed a little cumbersome. However, since all adjustments can be made form the front panel, it is nice to have both available when needed. I found the Compass control software very intuitive and comprehensive and, with the library of presets, set up time was very fast. Having used the Lake Contour on several occasions with a similar tablet setup, Compass affords you the same type of results as you walk the venue and make adjustments.

The Composite EQ in the Galileo provides a unique approach to system equalization. It yields appropriate correction with the least impact on phase response. Composite EQ combines complementary phase filters for correcting amplitude and phase artifacts from cancellation-based effects such as low-frequency resonances, with TruShaping EQ low-order filters, which enable correction of more broadly-shaped phenomena such as buildup artifacts and subjective shaping while keeping phase shifts to a minimum. In this venue using the array compensation within the Galileo, the amount of EQ required was minimal.


The Galileo 616 is another product from Meyer Sound that gives sound engineers the opportunity to perform their job better. For anyone using Meyer Sound self-powered loudspeakers, the Galileo is an addition engineers have been waiting for to optimize sound setup to achieve excellent sounding results for concerts and sound system installations.
