Frequently Asked Questions - Sub AS10 Pure Acoustics
How do I connect the Sub AS10 to my AV receiver?
Use a subwoofer cable (RCA) from the receiver's subwoofer pre-out to the Line In on the Sub AS10. Alternatively, connect speaker wires from the receiver's front speaker outputs to the Speaker Level Inputs and then to your speakers.
Where is the best placement for the subwoofer?
Place the subwoofer in a corner or along a wall for maximum bass. Avoid placing it in the center of the room. Experiment with the Phase switch and Crossover for optimal integration with your speakers.
Why is there no sound from the subwoofer?
Check that the subwoofer is powered on, the volume is turned up, and the cables are securely connected. Ensure the receiver's subwoofer output is enabled. Also verify the Standby mode is not active (the LED should be green).
What does the Phase switch do?
The Phase switch (0° or 180°) adjusts the timing of the subwoofer's output relative to the main speakers. Set it to 0° if the subwoofer is placed near the speakers, and 180° if it is placed behind you. Listen to which setting gives fuller, more cohesive bass.
How do I set the crossover frequency?
Match the subwoofer's Crossover dial (40-200 Hz) to your main speakers' low-frequency limit. For larger speakers, set around 80 Hz; for smaller satellites, set higher (100-120 Hz). Use the receiver's bass management if available.
Can the Sub AS10 be used with a stereo amplifier?
Yes, connect the amplifier's speaker outputs to the subwoofer's Speaker Level Inputs. The subwoofer will automatically filter out high frequencies for itself while passing the full signal to your speakers.
What should I do if the subwoofer hums or buzzes?
Ensure all connections are tight. Try plugging the subwoofer and your audio equipment into the same power strip. If the hum persists, use a ground loop isolator on the RCA cable.
How do I clean the subwoofer?
Unplug the subwoofer and wipe the cabinet with a dry, soft cloth. Do not use any liquids or cleaning chemicals, as they may damage the finish.
What is the warranty on the Sub AS10?
Pure Acoustics typically offers a 1-year warranty from the date of purchase. Keep your receipt. Contact Pure Acoustics support for warranty claims.
Can I replace the fuse myself?
Yes, if the subwoofer does not power on, check the fuse located near the power cord. Replace only with the same type and rating (e.g., T2A/250V). If it blows again, contact support.
