Understanding Physical Channels; Numbering Physical Channel On A Single Soundstructure Device - Polycom SoundStructure C16 Design Manual

Understanding Physical Channels

SoundStructure defines physical channels as a channel that corresponds to the actual inputs or outputs of
the SoundStructure system. Physical channels include the SoundStructure analog inputs, analog outputs,
submixes, the telephony interfaces, the conference link channels, and the logic input and output pins.
An example of physical channels is input 3, which corresponds to the physical analog input 3 on the
rear-panel of a SoundStructure device, input 10 (corresponds to analog input 10), and output 6, which
corresponds to the physical analog output 6 on a SoundStructure device, as shown in the following figure.

When designing with SoundStructure products, the analog inputs (such as microphones, or other audio
sources) and outputs from the system (such as audio sent to amplifiers) connect to SoundStructure's
physical channels.
The physical input channels and the physical output channels are numbered from 1 to the maximum number
of physical channels in a system. As described below, this approach is an enhancement of how traditional
audio signals are labeled and how their signals are uniquely referenced.

Numbering Physical Channel On A Single SoundStructure Device

As described previously, in single-device SoundStructure installations (for example using a single
SoundStructure C16), the physical channel numbering for the inputs and outputs corresponds to the
Polycom, Inc.
