Re: Monitor Audio BXW10
The IRS2092S from my SUB was also damaged.
To test the entire preamp part, remove the IRS209 and the FETs, enter a signal on the LINE INPUT and turn on the SUB. Check with the oscilloscope if the signal is present on the R150 which is the IRS input. Do not forget to increase the volume in the POT.
After exchanging the FETs and the IRS in mine, everything was fine.

Re: Monitor Audio BXW10
Dear
Also I could not locate the service manual, Monitor Audio is difficult.
Follows output class D sub.
It uses IRS2092 (IC108). Check that the Q102 and Q102 fets are good.
The IC109 is a microcontroller, which makes the protect and standby
Without the fets the circuit works and can measure the voltages. After a while comes protection....Leave a comment:
