Expansion and AT Inputs Overview

With the Extron Expansion Port (EXP), two EXP enabled devices can be connected for
bidirectional communication of 16 audio channels. When two units are connected, one
unit must be set as the Primary Unit and the other must be set as the Secondary Unit (see
Expansion Bus
AT inputs allow a DMP 128 FlexPlus model to receive signal from the audio network.
Network audio routing is done with Dante Controller (see
Figure 87.

Expansion and AT Inputs Processing

The expansion and AT inputs contain two processor blocks in their signal chain:
1. Automix Block
2.
Pre-mixer Gain Block
Expansion and AT Input Automix Block
One automix block is available for each expansion and AT input. This block functions the
same as the mic/line input automix block (see
information on configuring the EXP input automix block).
Expansion and AT Input Pre-Mixer Gain Block
The expansion and AT input pre-mixer gain block functions the same as the mic/line input
pre-mixer gain block (see
configuring the virtual return pre-mixer gain block).
