AVB Audio

Beside the analog audio, Executive Elite also supports digital audio input and

output. The AVB connection on the back of the Base DSP unit can be

connected to an AVB enabled network and delivers streams of output audio

data for each microphone, as well as can consume streams of input audio data

for each microphone. For information on how to set up an AVB network and

define AVB talkers and listeners see your AVB network management software.

USB Audio

Finally, the USB connector on the back of the Executive Elite Base DSP unit

provides independent audio streams, and can consume independent audio

streams for each of its microphones. Audio is not mixed in the Executive Elite

Base DSP unit; the USB connector delivers independent streams for each

microphone.

NOTE: It might be required to install additional driver software on the

connected computer enabling the separate audio channels to be

received on the device. Please see the documentation of your

computer for more details.

Synchronizing Executive Elite units

If more than one Revolabs Executive Elite Base DSP unit is used in an area,

the units should be synchronized to ensure best usage of the radio frequency

space, and best system performance. The Executive Elite system provides

three means to synchronize systems, the Sync Bus, the AVB network, and Over

the Air synchronization.

Microphone Density and Radio Frequency Interference

Synchronizing Executive Elite systems is important to maximize the density of

microphones that can be supported in one area. Non-synchronized systems in

the same space block a higher number of radio frequency channels than the

number of microphones they support, causing RF loss and audio drop-outs. It

is therefore important to synchronize all Executive Elite systems that are in

proximity with each other to limit the number of potential audio issues. There

is no disadvantage in synchronizing systems that are not in close proximity.

Synchronization only affects the internal clocks of systems, not the channel

selection they make for their microphones. It is therefore better to error on the

safe side and synchronize even systems not expected to be in direct proximity.

Maximum Density of microphones in one area is affected by the selected audio

quality and whether back-channel audio to the microphones is enabled or not.

It is also dependent on other wireless radio frequency traffic in the vicinity, and

whether that traffic is synchronized or not. Selecting the right RF power

The USB audio connection is enabled starting with Executive Elite software version 1.2.
