Noise Cancellation A process through which ambient noise is removed from a

signal.

Non-linear processing (NLP) NLP increaess the power of echo cancellation for difficult acoustical environments. NLP has four settings: Soft (6dB), Medium (12dB), Aggressive (18dB), and Off. NLP settings are found in the Acoustic Echo Cancellation window.

Number of Open Mics (NOM)/Constant Gain Mode Adjusts the output level based on the number of mics gated on and routed to an output.

O–R buses These four audio buses communicate NOM count and mic mixing

parameters.

Off Attenuation The amount of level reduction a microphone is given when the microphone is not gated on.

PA Adaptive Mode The XAP 400 recognizes how much loudspeaker audio is picked up by the microphones and then uses this level as the new ambient level when audio is present at the power amplifier. This prevents loudspeaker audio from gating on a microphone, while still allowing people in the room to gate on microphones as they speak.

PA Adapt/AEC Reference This G-Ware setting determines which output (typically for a loudspeaker) is used as a reference for an input.

PA Adapt/AEC Reference bus This bus carries reference information making it possible for an input to reference an output on another linked unit.

Parametric Equalizer (PEQ) A multi-band variable equalizer with control of gain, center frequency, and bandwidth. A properly configured PEQ enables the XAP 400 to offset speaker or room acoustic deficiencies.

Passwords The XAP 400 features several passwords to protect system

configuration.

•Front panel The front panel password prevents a user from changing settings in the front panel LCD menus. The password can be set from the front panel or through G-Ware.

•Macro The macro password is created in the Unit Properties window and makes it possible to lock certain macros. A locked macro can be run without the password. However, a password must be entered to edit the macro.

•Modem The modem password can be created serially using the MPASS command or through G-Ware in the Unit Properties window. The password is
