Understanding Digital Microphone Cabling Requirements

Up to four microphone arrays may be used with the SoundStructure products depending on the particular

SoundStructure model as described in the following figure.

Microphone Arrays Connected to SoundStructure Devices

The following table shows the number of analog inputs that are available based on the number of

microphone arrays that are used in a system. As an example, a SoundStructure C16 supports 16 analog

inputs. When used with two microphone arrays, 10 analog inputs are still available for use with other analog

inputs including microphones, program audio, etc.

Analog Inputs Available for Connected Microphone Arrays

Note: Connecting Digital Microphone Arrays to CLink2

In SoundStructure only applications, connect the digital array microphones to the

right CLink2 port (the port closest to the OBAM interface).

In SoundStructure and

the left CLink2 port on SoundStructure and connect digital microphones to either

CLink2 port on the

Version 2.0.1 of

to the SoundStructure device over CLink2. Later version of

support up to 4 microphone arrays on a SoundStructure device.

When the digital microphone arrays are connected directly to the SoundStructure device, the version of

firmware on the microphones are compared to the version of microphone firmware included within the

SoundStructure device. If the version of firmware on the microphones is older than the version of firmware

included with the SoundStructure firmware, the microphones are automatically updated with the version

firmware from SoundStructure.
