5. Setup Instructions

5.1 Receiver Installation

1. Placement: Position the receiver unit(s) in a central location, away from large metal objects or other wireless devices that may cause interference.
2. Antennas: Screw the supplied antennas securely into the antenna ports on the rear of each receiver module. Adjust them vertically for optimal reception.
3. Audio Connections:
   • For individual channel control, connect XLR cables from the CH 1-4 outputs of each receiver module to corresponding inputs on your audio mixer or sound system.
   • Alternatively, use the Mix Out XLR port on each receiver module for a combined audio signal from its respective 4 channels.
4. Power: Connect the supplied power adapter to the 13.5V Power In port on each receiver module, then plug the adapter into a suitable power outlet. Do not power on the receiver yet.

5.2 Microphone Setup

1. Gooseneck Attachment: Carefully screw each gooseneck microphone into its corresponding wireless microphone base.
2. Battery Installation: Open the battery compartment on the underside of each microphone base and insert the required batteries (typically AA, refer to the base for specific type and polarity).
3. Wired Expansion (Optional): If using wired expansion, connect additional wired microphones to the IN ports on the DigitalQuad-Conference-Extend or V-2 bases using XLR cables. For daisy-chaining, connect the OUT port of one base to the IN port of the next.
