Revolabs Executive HD™ Audio Connections
There are (8) 3.5mm mini-Phoenix inputs and (8) 3.5mm mini-Phoenix outputs on the back panel of
the unit (four on the 4-channel system) providing access to each channel‘s audio signal.
The provided mini-Phoenix connectors are designed for easy wiring. The three terminals (from left to
right) correspond to positive +, negative -, and shielded ground .
To connect audio In/Out on the Base Station
1. Use the screws on top of the connector to first loosen the terminals.
2. Insert an appropriate 3-conductor cable (2 conductors and shield) into the terminals.
3. Tighten the screw to secure the cable.
4. Push the connector onto the pins centered under the desired input or output port until firmly
secured.
The microphone output connectors need to be attached to the line-level (0dBu) input connectors of
an audio mixer. PHANTOM POWER MUST BE OFF. PHANTOM MAY CAUSE DAMAGE TO THE
BASE STATION.
The Base Station input connectors (also 0dBu) may then be attached to mixer channel outputs.
Because the system is full-duplex, the input connections provide the ability to hear program audio
using a 2.5mm earpiece attached to the microphone (supplied with the wearable microphone).
Depending on the application, it is possible to feed a single mixed channel back to all earpieces or,
alternatively, each user can receive a separate and unique channel. This would allow for translation,
personal hearing assistance or other services to be incorporated into an application.
Configuring the Executive HD
TM
Base Station
Each Revolabs Executive HD
TM
Base Station must be configured properly prior to use. Accurate
configuration is dependent on several variables such as:
1. How many Executive HD
TM
systems are being used together in proximity?
2. What type of 3
rd
party mute control is being used?
3. How large is the room?
4. Is Line Level or Mic Level signal required?
5. How do the mic mutes need to function?
Once these questions are answered, accurate configuration of the Executive HD base can be
achieved using a combination of the following methods.
Using Multiple Revolabs Executive HD
TM
Systems Together
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 not exceed 300‘ (90 meters). In addition, DIP switch #1 needs to be adjusted
on one or more of the units to represent the ‗Primary‘ and ‗Secondary‘ devices.
