NJM2153
SOUND ENHANCEMENT AUDIO PROCESSOR
■ GENERAL DESCRIPTION
The NJM2153 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 NJM2153 is suitable for mixer and effecter for musical
instruments, and high-end audio equipment requiring low distortion
and wide dynamic range.
