Input Balance Power Amplifier is a circuit which will filter the original signal with a shadow signal so it will get a low noise input and a clear signal that will be forwarded to the power amplifier. There is a shadow signal or weakened signal from various interference on long cable input, so expect to use long cable at input either microphone cable or output cable mixer and other audio accessories.
This Input Balance circuit is suitable for installation on Yiroshi Amplifier, SOCL 504, or another power amplifier with no input balance.
This input balance circuit is highly recommended, and it is recommended to use long cable accessories. Do not underestimate the use of long cables, therefore long cable usage is often disrupted by wild signal either from radio frequency, wireless, or other signals. Besides being used for field audio, this input balance circuit can also be used for car audio that already uses a power amplifier, which can filter out wild signals into the car's power amplifier. Usually called audio storing, where the output power amplifier will issue noise that will be louder if RPM up. This input balance circuit can overcome these constraints.
