CHAPTER 4: Operation

Front Panel

A correctly installed AP400 virtually runs by itself. Typical operations involve changing volume of an output, muting an input or output, or handling calls on the connected telephone handset. For most installations, a custom remote control (optional) will be used.

Controlling the volume

When participating in a conference, you might find it necessary to increase or decrease the volume of a particular output. For instance, when the audio at a distant location is too soft, adjust the output to the speakers so that the level is comfortable.

To adjust the volume

1.Determine which output needs to be adjusted.

2.Press the Outputs button, select the appropriate output and scroll to the Gain selection. Press Enter.

3.Adjust the gain level using the ▲ and ▼ buttons. You should be able to hear the volume level adjust while increasing or decreasing the gain.

4.Press Enter when you reach the desired volume level.

Muting

When participating in a conference, you might find it necessary to mute (or unmute) a particular input or output.

To mute or unmute an input

1.Determine the input you want to mute.

2.Press the Inputs button, and scroll to the desired input channel. Press Enter.

3.Scroll through the input parameters until you see Mute. Press Enter.

4.Use the ▲ and ▼ buttons to select On, then press Enter.
