User Manual

Filters

High-Pass and Low-Pass filters are provided to adjust to room and application

requirements. Use the High-Pass filter in rooms that have a high background

noise in the low frequencies (air conditioning, lighting fixtures, etc.). The Low-

Pass filter allows limiting high frequencies, based on the applications used. All

filters are bi-quad filters, reducing the signal by 6dB per octave.

The EQ works in four bands.

Gain adjustment is up to +/- 10dB around the center frequency within the

band, with drop-off to 0dB adjustment at the border frequencies.

Output

The VU meter shows the audio signal as provided to the analog ports. The final

gain stage provided here allows gain or trim to be applied to the signal before it

leaves the Executive Elite Base unit. “Line” level output provides the signal

with an additional 20dB gain compared to the “Mic” level output.

Audio Management

The Audio Management menu houses the Manage Groups and System Audio

pages.

Manage Groups

Microphone groups allow defining different mute behavior between individual

microphones or groups of microphones. Microphones in one Executive Elite

System can be assigned to any microphone group. Each group can then be

assigned a specific mute behavior.

NOTE: Up to 10 Mute groups can be created within one Executive Elite

base DSP.

All Executive Elite base DSP units have one group called “Default” which

contains all microphones of a newly configured system.
