Questions and answers
How do I connect two Velodyne ULD 15” with there controller to my Rx-z9 Yamaha receiver
To connect two Velodyne ULD-15 subwoofers with their controllers to a Yamaha RX-Z9 receiver, follow these steps:
1. Determine Output Type: The Yamaha RX-Z9 has a single line-level subwoofer output (mono).
2. Split the Signal: Use a Y-adapter (1 male to 2 female RCA) to split the subwoofer output from the receiver into two.
3. Connect to Controllers:
- Run one RCA cable from one side of the Y-adapter to the "FROM PRE-AMP" input (right or left) on the first ULD-15 controller.
- Run another RCA cable from the other side of the Y-adapter to the "FROM PRE-AMP" input (right or left) on the second ULD-15 controller.
- Leave the unused "FROM PRE-AMP" input and both "TO POWER AMP" outputs on each controller unconnected.
4. Subwoofer Connection: Each ULD-15 subwoofer connects to its respective controller using the dedicated servo interface cable.
This setup allows the Yamaha RX-Z9 to send the same subwoofer signal to both ULD-15 subwoofers.
