Function：
Convert the high-level signal from the power amplifier's speaker output port into a line output or microphone-level signal.
It uses a permalloy isolation transformer internally, which delivers excellent frequency response and anti-interference performance.
The converted low-level line output signal can be connected to the line input interfaces of active subwoofers, mixers, power amplifiers, or other audio devices.
The converted low-level microphone output signal can be connected to the microphone input interfaces of mixers, sound cards, or other audio devices.
