EC Reference bus

This bus provides a system-wide echo canceller reference signal. When multiple AP800 units are linked together and will be using only one output channel to drive the loudspeaker system, that output must be defined as the sample reference which will be used by all of the linked AP800s for echo cancellation. It allows the reference signal to be passed to additional G-Linked mic channels and their associated echo cancellers. For echo cancellation to function properly, the output which the master unit will use as the EC reference must be identified to the slave units via the G-Link (see Figures 2.36 & 2.37 for routing configuration).

The following example illustrates the echo cancellation setup necessary to

Slave Unit

Because the slave unit will not be using one of its own outputs as the EC reference, “EC Ref #1” must be defined as the “G-Link EC Ref” only (as shown in Figure 2.21). The slave unit will then use the master’s defined output (in this case, output D) as its reference for echo cancellation.
