The On-Q 717AU100WH Impedance Matching Volume Control provides impedance matching selection via jumpers labeled 1x, 2x, 4x, and 8x, with 1x being non-impedance matching. To select the correct impedance setting for your speakers, follow these steps:
1. **Understand Speaker Impedance:** The impedance of your speakers should be known. The volume control is designed for 8 ohm speakers, but if your speakers have a different impedance, you will need to calculate the parallel impedance and multiply it by the appropriate multiplier (X2, X4, or X8) to match the load to the amplifier's capabilities.
2. **Impedance Matching:** The multiplier settings correspond to the jumper positions on the volume control. Setting #1 corresponds to jumper position X1, setting #2 to X2, setting #3 to X4, and setting #4 to X8. Ensure that you set the jumpers according to the impedance requirements of your speakers.
3. **Setting the Jumpers:** Adjust the jumpers on the volume control circuit board to the appropriate setting based on your speaker impedance. In most cases, the jumpers for each speaker's output will be set the same, but make sure to set them correctly according to your setup.
4. **Frequency Variation:** Remember that impedance varies with frequency, so the load seen by the amplifier is not constantly stable. The multiplier settings help to match the impedance at different frequencies.
By following these steps and referring to the provided instructions, you can properly set the impedance matching jumpers on the On-Q 717AU100WH Impedance Matching Volume Control to ensure optimal performance with your speakers and amplifier.
