If more than one Revolabs Executive HD ™ Base Station is used in an area, each unit needs to be
interconnected with a synchronization (BUS) cable using a standard 3.5mm mini-Phoenix connector
and any 26AWG or better shielded cable. The maximum distance from the Primary unit to any
Secondary device must n
ot exceed 300‘ (100 meters). In addition, DIP switch #1 needs to be
adjusted on one or more of the units to represent the
‗Primary‘ and ‗Secondary‘ devices.
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 microp
hone channels within a 100‘ (30 meter) radius in North America is 16
channels (High Definition mode) or 32 channels (Max Density mode). The maximum number of
chann
els within a 100‘ (30 meter) radius for an EU frequency system is 24 channels (High Definition
mode) or 40 channels (Max Density mode). (See Section

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
