The IRS series is used widely by Peavey, Alto, Mackie, Shure, Behringer and many more manufacturers with good reliability. Having stated that, if they were to pay more attention to the power supply issues they have, the power supplies would power the IRS range for longer.
The amount of power is down to the output transistors as they will only power a few watts on their own.

Default IRS2092 single supply instead of +/-60V can we use single +120V

Im planning to use single supply for IRS2092 just like IR2110 in the following image attached.

Did anybody built that circuit? Full bridge with post filter feedback and single supply?

Some bridged class D amps use a single supply with no issues.
