Description

The entire amplifier is constructed using the latest instrumentation amplifier technology.
This technology uses a fully balanced signal path from the input terminal to the power amplifier stage, which not only provides excellent characteristics such as CMRR (Common Mode Rejection Ratio) and distortion, but also makes the amplifier more resistant to changes in the surrounding environment such as external noise, improving its stability and reliability as a power amplifier.
