THE ELECTRONICS PACKAGE
The Electronics Package is fabricated of aluminum
alloy and houses the main electronic components. It is
both the brain and powerhouse of the Audio Module,
integrating processor and amplification.
The Electronics Package connects to the Loudspeaker
Cabinet through two 108-pin connectors, which carry the
amplified loudspeaker signals, a digital bus, and power
for the active electronic components in the front of the
Audio Module.
The Electronics Package integrates:
• 5x 16-channel digital amplifier modules — providing
individual amplification and DSP control to each of
the 80 drivers in the first two matrix layers
• 2x AC to DC amplifier “Smart Rail” power supply
modules
• 2x DC amplifier energy storage modules
• the “Core” — integrating a processing module
combining a high-performance Field Programmable
Gate Array (FPGA) and a dual-core ARM®
Cortex™-A9, with an independent AC to DC ancillary
power supply
• an optional “Dante Module” — providing Dante audio
networking connectivity
• 8x temperature-controlled fans — actively cooling
the Electronics Package
• the “Display Panel” — providing information on the
Audio Module’s ID and status
THE DISPLAY PANEL
The backside of the Electronics Package integrates
the Display Panel, which displays Audio Module status
and error messages, and provides basic information
like IP addresses and firmware version. The resistive
touch screen responds to pressure and therefore can be
operated by a fingertip, even when wearing gloves, or by
an appropriate stylus tip (pen).

The touch screen utilizes a thin
flexible sheet that may be damaged
by sharp objects or heavy treatment.
