The three terminals of the BUS connector should be wired in parallel via either a daisy chain
connection or terminal block split. The three contacts of the phoenix connector are as follows from left
to right.
1. Sync
2. Master Mute
3. Ground
Set one Base Station as the Primary device by putting DIP switch #1 to the ‗Off‘ position. The other
units must be set as Secondary devices by putting DIP switch #1 to the ‗On‘ position. In this
configuration, the Primary device manages the entire system, distributing microphone transmission
across available channels to maintain frequency integrity, and coordinating system muting.
Primary (DIP switch 1, Off – default): This designates the Base Station as the master control unit.
Secondary (DIP switch 1, On): Additional base stations to be used in the same area must be
connected via the BUS and be set to REMOTE mode to ensure synchronization of timing clocks
between bases in order to prevent interference.
Note: Whenever a DIP switch is toggled, the base unit should be reset, or the power should be
cycled for the switch setting to be registered.
Warning: The switch must be in the „Primary‟ position for a single Base Station system, which is the
factory default setting. Microphones will not function if the switch is in the „Secondary‟ position and no
„Bus‟ cable is connected.
The maximum number of microphone channels within a 300‘ (90 meter) radius in the Americas or
Japan is 16 channels (High Definition mode) or 32 channels (Max Density mode). The maximum
number of channels within a 300‘ (90 meter) radius for a EU or CN frequency system is 24 channels
(High Definition mode) or 40 channels (Max Density mode). (See Section Using the Revolabs HD
Control Panel Software)
Note: Using Revolabs Executive HD systems in the same area(s) without the bases connected via
the BUS will result in interference
Warning: Using the maximum number of Revolabs HD Microphones in a given will occupy
100% of the available RF bandwidth. Any other wireless device operating in the same
frequency could cause significant interference with the Revolabs HD Microphones. It is
recommended that no other DECT or DECT 6.0 products be used within operational range of
the Executive HD system(s).
