Ez Tools Software Speakercraft Bb275 Reviews

Try this to isolate where it is coming from. Either the zone amps are defective, which is not likely, or the main amp is at fault. Hard to believe they are mis-wired, they typically are foolproof in this area.

The high current design makes them ideal for installations that require multiple speakers to be connected to one amplifier. No reviews anywhere that I could find, so I decided to take a chance with the low sale price of $269. So far this unit has.

At the main controller, try the two zones that are good and plug them into the 4 bad zones one at a time and see if you get the same symptom. If you do, then it is not the main controller and something common to the 4 zones is causing the issue. If they are wireless, then you my have interference so check if you can select different channels. E Answered on Nov 16, 2012. Hello If your amp is still undr warrenty, send it back, do not void warrenty. If it is already out of the warrenty period you can open the amp up untill you see the cicuit board. Now you trace the board to the sound channels, once here have a look at the capasitors, you will easily see if it has overheated.

You can replace this yourself or take it to a repair shop where they will fix it for cheap. But before you try this. Once the amp is opened up, locate the fuse and see if the fuse is still working properly. If all else fail, take it to a repair shop and first get a qoute on how much it will cost you to fix and then decide if it is worth the money to fix. Please rate this. Best regrds Answered on May 12, 2011. Hello, I am a service engineer and have serviced a few of these units, you can send it back to speakercraft direct but they will charge you an arm and a leg for it, they are very 'cloak and dagger' about supplying parts and service info to anyone else including dealers.

I must say from the outset that these units are not a straight forward amp like some of the posting are suggesting. Any professional engineer will not be able to diagnose a problem for a written symptom.

These systems require a programmer via a software driven interface to set them up which only a dealer will have. So in some cases a re program can solve the issues. The amp's (6xstereo modules) are very low powered at about 5w per channel so they are a common problem and each one cost's about £100.+VAT and then labour cost's, but they are loaded with a very complex matrix system for looping video and audio plus the CAT5e localised Keypad's. These are £5K systems when new, but you probably know that.

One way for you to get an better idea of were the problem might lie is to find a pair of powered speakers like PC speakers and connect them to the 'Pre-Out' connections on the rear of the unit located directly above the EZ-PAD connection on the rear. You should be able to hear audio out of these outputs (one for each zone) and depending on the zone you connect to you will hear the corresponding audio that is selected in that area on the keypad. If you do hear audio from each zone but not from the speaker outputs then it could be a number of problems probably caused by one or more of the AMP modules failing (which is common). If you power up the amp with it connected and don't pass any audio through it, put your ear right up to the speakers in each zone and you should hear a VERY faint hissing coming from the speakers (which is good). Which ever zones are not emitting that hissing correspond to the amp modules that are faulty.
