Meyer Sound Galileo GALAXY 816-AES3 – 8x16 Networked Loudspeaker Processor with AES

The Meyer Sound Galileo GALAXY 816-AES3 is a networked loudspeaker management processor built to drive and align larger Meyer Sound line array and point-source systems, with 8 analog or digital inputs and 16 outputs — available in analog and AES/EBU digital — in a 2RU chassis. It provides 24-bit/96 kHz processing, Milan-certified AVB networking, and Meyer Sound's full processing toolkit — parametric EQ, U-Shaping EQ, delay matrix, and Product Integration for matching multiple loudspeaker models in one coherent system. The AES3 digital output makes this model the right choice when downstream equipment expects a digital audio handoff rather than analog.

Housed in a 2RU, 19-inch rack-mount chassis, the GALAXY 816-AES3 shares its core processing architecture with the standard GALAXY 816, running at up to 64-bit internal resolution with an ultra-low noise floor and roughly 0.6ms of latency from input to output. Control runs through Compass Control Software on Mac or PC, the Compass Go iPad app, or Spacemap Go for spatial audio design, with straightforward third-party integration for Crestron and similar control systems. Input processing covers gain, delay, and 5-band parametric/U-Shaping EQ; output processing adds polarity reversal, 10-band parametric EQ, Low-Mid Beam Control, and atmospheric correction. Two SIM bus ports allow direct connection to Meyer Sound's SIM audio analyzer for on-site measurement and verification. The built-in summing and delay matrix lets a designer assign gain and delay at every routing cross point, so a single loudspeaker can serve as an output for multiple independently processed input signals.

Key Features

• 8x16 I/O with AES3 digital output — 8 audio inputs (analog or AES/EBU, selectable in pairs) and 16 outputs available in analog or AES/EBU digital, in a 2RU chassis.
• Milan-certified AVB networking — all audio and control data pass over a single network cable, interoperable with other Milan-certified devices regardless of manufacturer.
• Ultra-low latency — approximately 0.6ms analog-in to analog-out, with up to 64-bit internal processing resolution.
• Full EQ and delay toolset — 5-band parametric and U-Shaping EQ on inputs, 10-band parametric EQ plus Low-Mid Beam Control on outputs.
• Built-in summing and delay matrix — assign gain and delay at every routing cross point across all 16 outputs.
• Product Integration — Delay Integration settings acoustically match different Meyer Sound loudspeaker models combined in the same array.
• SIM audio analyzer connectivity — two SIM bus ports for direct on-site measurement without an external interface.
• Third-party control — network-enabled controllers such as Crestron or AMX, plus OSC and text command support.

Typical Applications

Broadcast studios, large performing arts venues, touring and rental sound systems producing a digital output feed, multi-zone houses of worship, corporate auditoriums and arenas, themed entertainment and immersive venues, stadiums and large-scale installations.

Frequently Asked Questions

What's the difference between the GALAXY 816-AES3 and the standard GALAXY 816?
Both provide the same 8x16 I/O count and chassis; the 816-AES3 adds AES/EBU digital audio output alongside analog, for systems that need a digital audio handoff to other equipment such as broadcast or recording chains.

When should I choose the AES3 model over the standard GALAXY 816?
Choose the 816-AES3 when downstream equipment — a broadcast console, recording system, or digital amplifier — expects an AES/EBU digital feed rather than analog output.

Can the GALAXY 816-AES3 network with standard GALAXY 408 or 816 units?
Yes. All GALAXY processors are Milan-certified and interoperate on the same AVB network regardless of model, so a system can mix analog and AES3 units as required.

Does using AES3 outputs affect latency or processing?
No. The 816-AES3 shares the same core processing architecture and approximately 0.6ms latency as the standard GALAXY 816; only the output signal format differs.

Do you provide system design and commissioning for Galileo GALAXY processors?
Yes. Our engineers handle Meyer Sound system design, GALAXY configuration, and commissioning as part of a complete audio system project.
