Frequently Asked Questions - Impact X12 VELODYNE
How do I connect the Impact X12 subwoofer to my receiver?
Use an LFE cable (single RCA) from the receiver's subwoofer output to the LFE input on the subwoofer. Alternatively, use line-level RCA cables from the receiver's pre-out to the subwoofer's line-level inputs.
Why is there no sound from the subwoofer?
Check that the subwoofer is plugged in and the power is on. Verify the receiver's subwoofer output is enabled. Ensure the volume knob on the subwoofer is turned up and the crossover is set appropriately.
How do I set the crossover frequency?
Set the subwoofer's crossover to match your main speakers. A typical starting point is 80 Hz. Adjust by ear for a smooth blend; lower for larger speakers, higher for smaller ones.
What does the phase switch do?
The phase switch (0° or 180°) allows you to align the subwoofer's output with your main speakers. Try both positions and choose the one that produces the fullest bass at your listening position.
Can I use this subwoofer with a stereo system without a subwoofer output?
Yes, use the speaker-level inputs on the subwoofer. Connect the amplifier's speaker outputs to the subwoofer's speaker-level input terminals. Then from the subwoofer's speaker-level outputs to your main speakers.
The subwoofer turns on but has no audio, what could be wrong?
Check the audio source and cable connections. Try a different cable. Ensure the receiver is sending a bass signal. If using LFE, the source material must contain bass content.
How do I clean the subwoofer?
Unplug the unit. Wipe the cabinet with a dry, soft cloth. For the grille, use a vacuum with a brush attachment. Do not use any liquids or harsh chemicals.
The subwoofer makes a humming or buzzing noise. How to fix?
Hum is often caused by a ground loop. Ensure all components are on the same circuit. Try a ground loop isolator on the RCA cable. Also check that the cable is not running parallel to power cords.
What is the recommended placement for the subwoofer?
Place the subwoofer in a corner or against a wall for maximum bass output. Avoid corners if the bass is too boomy. Experiment with placement to achieve even bass response in the room.
How do I replace the fuse?
Unplug the subwoofer. Locate the fuse holder near the power input. Pry open the fuse holder and replace with the same type and rating (e.g., 2A 250V). Reinsert and plug back in.
