The product is suitable for OCL or OTL output power amplifier circuit, not suitable for BTL!
Use independent windings to supply power to the protection circuit, so that the power loop can be closed, otherwise the speaker ground and signal ground are mixed together, which will easily produce interference and hum. (The common use of the front-level power supply and the protection circuit can easily produce humming).
