	When multiple							AP400s
✍ are used in a system, the
	gate parameters							on all
units must be set the same.

A good way to remember the new passcode is to create a word using the first letters of the buttons. For example, using Rooms as the passcode would be the button sequence: Routing, Output, Output, Meter, System.

Device ID

The Device ID menu selection lets you choose from eight G-Link network IDs (0–7). See Device IDs on page 13.

Unit ID

The Unit ID number allows you to view the read-only unit address set at the factory. This unique ID number identifies that particular unit and cannot be changed.

Mixer mode

This setting allows you to set to master or slave mode. See page 13 for details.

Gate parameters

There are nine gate parameters that can be adjusted via the front-panel LCD (Figure 2.8). The parameters in this submenu include: PA adaptive mode, maximum number of mics, first mic priority, last mic mode, gate ratio, off attenuation, hold time, decay rate, and manual ambient.

PA adaptive mode

The AP400 recognizes how much loudspeaker audio is picked up by the microphones. It then uses this level as the new ambient level when audio is present at the power amplifier (see Figure 2.9). 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.

Maximum number of mics

This parameter sets the maximum number of microphones that can be gated on at any one time. This range can be set from one to eight microphones or off. The default setting is four. To set the maximum number of microphones, scroll through the number ranges (one through eight), select the desired number and press Enter.
