Some basic trouble shooting is required here. First you need to see if it is a problem from your source or the sub. Try a different source to the sub-woofer and see if it changes the response. If still nothing on the sub, then most likely there is an issue with the amp or driver. Check to see if there is a fuse on the sub, if so, it could be blown. There could also be an issue with the auto switching circuit on the subs amp, in that case, it would need to be repaired in the shop. But before that I would check all of the connections to the sub, and also to the driver in the cabinet. If everything looks good, then put some type of source directly to the woofer to see if it works, if you get sound, then looks like the amp has a problem. Again a repair or replace issue.

How do i fix my infinity entra 10 inch 150 watt powered subwoofer. fuse is good, green led is on so it is getting power


Best to start at the beginning. You have it connected properly? Are you using the line level, direct or speaker inputs? What output on your receiver are you using?
Have you adjusted the volume control?
If you have everything correct, are you the original owner? It's an older model so if you are the original owner what happened when it stopped working? Noises, fade out, just wouldn't turn on one day.

Are you capable of doing some minor electrical work? Can you read a schematic? Can you recognise electrical parts? If the answer to any of these last three questions is no, you need to take it to someone that has the ability to do electrical repairs. If the answer to all three is yes you can fix this yourself.

Why does my MCS sub 10 not turn on?


Is that the right part number, MCS 10, and not MCS100?

The MCS systems use a basic sub which is matched to the satellites. There's very few controls other than level on the MCS100. So as long as the power light is illuminated the there's very little other than the volume control that could be set wrong on the sub. So what it comes down to is either

  1. a blown fuse (no power at all at the sub);
  2. a broken input (#1 cable, #2 sub input socket, #3 blown sub plate amp);
  3. incorrect connection at the receiver end or the wrong settings

As a quick test, unplug the sub cab from the amplifier/receiver end. Switch on the sub and turn the volume down all the way. Briefly put your finger across to short the RCA/phono tip and ring. The sub should make a buzzing sound. You now know that the sub is working and the cable appears to be okay

Switch off the sub and reconnect the phono/RCA to the sub out socket on the receiver. You now know it is connected correctly.

Go in to the receiver's menu and check the speaker settings. Is subwoofer present? Yes/No

Are the satellites all set to Small? (they should be with this system)

Are you playing a 5.1 source in DD or DTS to ensure that the sub gets a signal? Play a BD or DVD.

On the speaker balances, is the sub channel set to 0dB?

As long as all the above is set as listed, then the only things stopping the sub working would then be insufficient volume at the sub's Vol control (so increase it), or an intermittent cable connection (wiggle the cable), or a broken subwoofer out signal at the receiver.

Is there a on of switch and is the green or red light to be on


There is no main AC power switch on the BU series; it's in standby mode whenever it's plugged in.

When playing music normal LED color should be green. After no signal for 10 minutes or so it will turn back to Red (Standby)

AR SW-30 subwoofer doesn't switch to standby mode when off


Disconnect its input cable to see if a true lack of signal lets it go to sleep. If not, it has a bug. Otherwise, you probably have some sort of signal present on the sub cable.
