Frequently Asked Questions - Impact-12 VELODYNE
How do I connect the Impact-12 subwoofer to my receiver?
Connect the subwoofer’s LFE input to the receiver’s subwoofer output using an RCA cable. For speaker-level connection, use the binding posts with speaker wire.
What is the best placement for optimal bass?
Place the subwoofer in a corner or along a wall for maximum output. Experiment with placement to avoid nulls and peaks; a front corner near the main speakers often works well.
Can I use the Impact-12 with a stereo amplifier without subwoofer output?
Yes, use the speaker-level inputs. Connect the amplifier’s speaker outputs to the subwoofer’s binding posts, then from the subwoofer’s outputs to your main speakers.
How do I adjust the crossover frequency?
Turn the crossover control knob on the subwoofer’s back panel. Set it to match your main speakers’ low-frequency limit, typically between 80-100 Hz for most systems.
Why is my subwoofer not turning on?
Check the power cord connection and ensure the wall outlet is live. Verify the auto-on switch is set to ON or Auto. If using signal sensing, ensure a signal is present; try setting the switch to ON manually.
What does the phase switch do?
The phase switch adjusts timing alignment between the subwoofer and main speakers. Set to 0° for in-phase or 180° for out-of-phase; listen to find which setting gives stronger, clearer bass at the listening position.
How can I clean the subwoofer grille?
Remove the grille gently. Vacuum the cloth with a soft brush attachment or use a lint roller. For stubborn dirt, lightly dampen a cloth with mild soap and water, then blot dry.
What is the warranty period for the Impact-12?
Velodyne typically offers a 2-year limited warranty for subwoofers. Verify your purchase for exact terms; keep your receipt as proof.
Can I replace the driver myself?
Yes, the driver is user-replaceable. Order a replacement from Velodyne or a dealer. Disconnect power, remove the grille, unscrew the driver, and disconnect the wires; install the new driver in reverse.
What is the recommended maximum volume level?
Avoid driving the subwoofer into distortion. The maximum usable volume depends on the source and room; if you hear distortion or the subwoofer shuts down, reduce the volume or gain.
