Test it on a different socket, and ensure that the cube audio cable at the back is properly connected.

Read the first pages of the user manual to find connections diagrams and instructions.

If the unit does not start at all, then it is defective. In that case have it replaced.

My definitive technology pro cinema 600 sub stopped working


theres a setting is on the subwoofer itself, not the AVR. It usually has 3 positions: On, Auto, Off. Auto allows the sub to "sleep" when it's not being used, and to power back up fully when it senses a signal. Maybe change to On position which would bypass that auto mode

The subwoofer by DT ProCinema 600 doesn't work


I had the same problem when I wanted to swap my PCicon1.png 1000 for the PC 2000. The later interfered with my view on the tv. What I did was raise the tv on a couple of pieces of MDF. I painted the edges of the MDF to match the tv stand. Looks great - is very solid as far as support for the tv - and allowed me to get the PC 2000smile.gif

Where to buy replacment speakers


This is a specialty speaker so I do not recommend looking anywhere but with definitive for this. Their products are like high performance sport car assessories, where they are "tuned" to work as a cohesive system. If you really don't want to go that route, start with partsexpress.com.

You need to make sure the sub is plugged into the sub pre out connector. Not the the sub out. You might also have to go to the user menu and tell the unit that you are using a sub.

Unfortunately, the most common problem with powered sub woofers, including definitive technology, is that the capacitors inside dry out. To check the speaker, you can connect any line level audio source (like an mp3 player) to the speaker and see if it comes on. If it does come on, then you will know the speaker is ok. If not, then the speaker will need servicing. Powered sub woofers are not usually a DIY project.

Definitive Pro-Sub 1000 subwoofer replacement fuse.


Fit a 3 or 2.5 anything lower, if you can get away with it, but nothing higher.
However the chances are that it blew due to an overload, often caused by a shorted semi-conductor acting like it was a piece of wire. So even fitting a smaller one and it blowing again doesn't mean it's due to the rating.

Prove it's alive by feeding it the signal from any other source, like Left or Right Tape Out. Use FM as the source to keep things simple. Then we can move forward with analyzing the correct failing unit.

Placement of definitive supercube 2


Make shure your crossover on the amp is set at 80hz. If closer to side walls you will get more response but may be muddy. Make sure it goes low enough to comliment the klipchs.
GOOD LUCK
