Product Overview
Instruction
FMSH’ FM62429 is a dual channel electronic volume controlled with 2-wire rial date. It is
designed special to adjust the range of audio-digital. The build-in reference circuit can constitute an
electronic volume with less external parts. The FM62429 is completely compatible with the
M62429P/FP of Mitsubishi.
Features
Controlled with 2-wire rial data
Independent control allowed in each channel
Build-in reference circuit
Gain range: 0dB to - 83dB(1dB/step), - ∞
Low noi and low distortion
