Setup
The Cubilux AS-X2 is a plug-and-play device that does not require any external power supply. Follow these steps to set up your XLR selector:
- Identify Inputs and Output: The unit features four stereo XLR input pairs (IN1, IN2, IN3, IN4) and one stereo XLR output pair (OUT).
- Connect Input Sources: Connect your XLR audio sources (e.g., microphones, mixers, DACs, DVD/CD players) to the desired input ports (IN1-IN4) on the rear panel of the AS-X2. Ensure secure connections for both left (L) and right (R) channels if using stereo sources.
- Connect Output Device: Connect the XLR output (OUT) of the AS-X2 to your amplifier, speaker, monitor, or other audio receiving device.
- Verify Connections: Double-check all XLR cable connections to ensure they are firmly seated and correctly oriented.
The AS-X2 supports phantom power pass-through, allowing condenser microphones requiring phantom power to function correctly when connected through the selector, provided the phantom power is supplied by the connected mixer or audio interface.
