Note: Changes to the IP Configuration will only take place once the Base Station has bee rebooted.
Update Firmware
Executive HD Systems are field upgradable for the firmware portion of the Base Station and
Microphones. The firmware must be sent to the Base station and Microphones separately using the
HD Control Panel program. See Updating Revolabs HD Firmware for more information.
Serial Control Processor
The Serial Control Processor allows the use of third party control system or DSP to monitor and
control the Executive HD Base Station and Microphones. See Using the Serial Control Processor for
more information.
Audio Mode
There are two audio modes to choose from when using an Executive HD System. ‗High Definition'
mode (default) which provides 50Hz-20KHz audio ‗Max Density' mode which provides 50Hz-12KHz
audio. While ‗High Definition' mode provides the highest audio bandwidth, ‗Max Density' mode
provides the ability to use more mics in a given area. This configuration setting can also be controlled
using the Base Station front panel display.
Note: A change to the Base Station Audio Mode will result in an automatic system reboot.
Low Pass Filter
Each Executive HD Audio Mode is set by default to use a predetermined Low Pass Filter (LPF) to
optimize the microphone performance. This LPF can be deactivated in each mode to allow the
maximum available audio bandwidth to pass. In ‗High Definition' mode the LPF is set to 15KHz and in
‗Max Density' mode the LPF is set to 8KHz.
Table Top Master Mute
The Executive HD System provides two options for microphone mute performance.
The default option allows each microphone to have its own individual mute capabilities as well as a
Master Mute function that will lock all mics into a muted state until the function is disabled. The
Master Mute can only be triggered by a control system via RS-232 or Ethernet.
