1、 1. Overview The V2153M is a sound enhancement audio processor for professional audio equipments.It regenerates high definitive and nearly real sound.The internal VCA（voltage controlled amplifier） suppresses the boost gain in high band to reduce noise when faint signals are inputted.The V2153M is su

2、itable for mixer and effector for musical instruments,and high-end audio equipment requiring low distortion and wide dynamic range. Its features are: Operating Voltage (9 to 18V) Low Operating Current (5.2mA typ.) Low Output Noise (20uVrms typ. at ON) Low Distortion (0.02% typ. at ON) Internal ON/OF
