How many speakers can I hook up to a QSC amplifier in bridge mode.

It all depends on the Ohms. If too low it will put the amp in protection mode but should reset. If you series or parallel to get 2-4 ohms min. it should not overheat the amp.

Soon as i turn on my QSC RMX2450 the clip light comes on for Ch 2

Sounds like an output going bad. Try to get some electronic contact cleaner and spraying on the circuit board. If its corroded this will help clean the circuit..

Im a dj and i keep blowing one channel on my amp

Hi.

Check speaker wiring. An amp final channel usually blows because of excessive draw from speakers. This often happens because one of the speaker is shorted inside or because of a wiring problem.
Also ensure that speakers are responding to specifications. Speakers that are out of the amp Ohms range will do the same thing in a while.

Naturally you can also blow an amp final by pumping volume to the max for a while. The transistors or the STK ICs in the final section will overheat and blow.

Regards.

Ginko.

BEOSOUND9000 - When BEO4 is set to 'CD' 'Shift 90258' for test mode, when I then press '72' the message on the BEOSOUND 9000MkIII states 'Wrong SRC/TM' even though It worked at the start of the repair

The message "Wrong SRC/TM" on a BEOSOUND 9000MkIII when pressing '72' while in test mode (Shift 90258) and set to 'CD' could indicate that there is an issue with the source selection or the test mode itself. To resolve this issue, you can try the following steps:
  1. Check the source selection: Make sure that the correct source (CD) is selected on the BEO4 and that it is functioning properly.
  2. Check the test mode: Verify that the test mode has been activated correctly and that the Shift 90258 code has been entered correctly.
  3. Check for firmware updates: Make sure that the firmware on the BEOSOUND 9000MkIII is up-to-date. If there is a firmware update available, install it to resolve any issues with the test mode.
  4. Factory reset: If the above steps do not resolve the issue, a factory reset of the BEOSOUND 9000MkIII may be necessary. This will restore the unit to its original settings and resolve any software-related issues.
If these steps do not resolve the issue, you may need to seek further assistance from the manufacturer or a professional repair service. It's important to follow the manufacturer's instructions and safety guidelines when attempting to repair or troubleshoot your system to avoid damaging the unit or causing potential harm.

Lasko silent room heater Model Number 5628

I apologize, but wiring diagrams for specific home appliances are not readily available to the general public. These diagrams are usually confidential and used by authorized repair technicians only. If you need to repair or replace the cord on your Lasko silent room heater Model 5628, I would recommend reaching out to the manufacturer or an authorized repair service for assistance. They should be able to provide you with the information and support you need to safely and effectively repair or replace the cord.
