Device Parameters

To change the gain of an entire row or column you may simply click on the column or row header (any of the labels 1-D on the columns or the rows) to see a collection of sliders as shown in Figure 13.

The outputs R1 and R2 correspond to the echo canceller references REF 1 and REF 2. While these outputs are not physical outputs on the product, they allow you to build the echo canceller reference without using physical outputs from the device. In the example in Figure 12, we used stereo program audio and consequently had a local left output (Output C) and a local right output (Output D) in the room. The echo canceller reference R1 included both the codec audio (Input A), the phone add audio (Input B)
