AEC Reference

There are two options for this parameter: EC Ref 1 and EC Ref 2. EC Ref 1 (default) references Output D (typically used for connection to a power amp and speaker). EC Ref 2 is not factory set. EC Ref 2 is typically used in sound- reinforcement applications. This allows for the AP800 to provide two zones of sound reinforcement per AP800 unit.

Echo Canceller

Activate or deactivate the echo cancellation feature for each gated input. Factory default is on.

NLP Adjust

Non-linear processing (NLP) has four settings: soft (6dB), medium (12dB), aggressive (18dB), and Off. NLP adds echo cancelling “horsepower” to the echo canceller in difficult acoustic environments. Care should be taken when using NLP because of the corresponding trade-offs which potentially include suppression and half-duplex operation. The factory default is Soft.

Inputs A, B, C, D

The parameter submenus below this level control how inputs A, B, C, and D deal with input audio. There are three parameters that can be applied to these inputs: gain adjust, AGC, and mute (see Figure 2.15).

Gain Adjust

This adjusts each input’s gain (ranging from -20dB to 20dB). In conjunction with the LCD readout and the LED bar graph, all gated inputs can be simply calibrated for the right level on the mix bus. The default setting is 0dB.

AGC

Each input can use automatic gain control (AGC). AGC keeps softer and louder input audio at a consistent level. This feature is disabled when shipped from the factory.

Mute

This parameter mutes a particular input channel.
