A good way to remember the new passcode would be to create a word using the first letters of the buttons. For example, using Rooms as the passcode would be the key sequence: routing, output, output, meter, system. The passcode must be five characters long.

Device ID

The AP800’s device ID is set in the Device ID menu selection. There are eight G-Link network positions (0–7). See Device IDs, page 10.

Unit ID

The Unit ID menu selection allows for accessing the read-only address set at the factory. This unique ID number identifies the particular unit and cannot be changed.

Gate Parameters

There are nine gate parameters that can be adjusted via the front-panel LCD (see Figure 2.7). The parameters in this submenu include last mic mode, maximum numbers of mics, PA adaptive mode, first mic priority, gate ratio, off attenuation, hold time, decay rate, and manual ambient.

PA Adaptive Mode

The AP800 recognizes how much loudspeaker audio is picked up by the microphones and uses this level as the new ambient level when audio is present at the power amplifier (see Figure 2.8). This prevents loudspeaker audio from gating on a microphone while still allowing people in the room to gate on microphones as they speak. This mode can be turned on (default) or off by selecting the option and pressing Enter. ClearOne Communications recommends leaving this feature on.

Ambient Level

When the AP800 detects audio in the power amplifier, it increases the ambient level to match the level of the speaker audio at the microphones. This prevents the speaker audio from turning on the microphones.
