Routing Guidelines

The audio matrix consists of sources and destinations. There are 25 possible input sources and 17 destinations.

Internal Subbus

Subbus 1, 2. The AP800 is equipped with two internal sub-mix buses. The subbus is a matrix output which allows signals to be mixed and level controlled. The subbus is then made available as an input to the matrix for further signal routing.

G-Link bus

This digital bus appears on every Audio Perfect product. This mix-minus bus routes audio to any destination on the G-Link network. The AP800 has four digital buses: X-bus, Y-bus, Z-bus and G-Link EC Reference bus (see Echo Cancellation Setup below). See page 6 for complete descriptions of each bus.

Echo Cancellation Setup

EC Reference 1, 2. The EC reference tells the microphones which output will be used as the sample reference for echo cancellation. EC REF 1 (default) references Output D (typically used for connection to a power amp and speaker). A unit will support one common EC reference for all eight microphones (as shown in Figure 2.19). However, in the case of splitting a single AP800 unit into two zones or two mic mixers, it will be able to support two EC references – one for each zone or mixer.
