General Description
The NJU26040-18A is a digital audio signal processor that provides the function eala / eala Rebirth or eala expand speaker + 128tap FIR filter. The NJU26040-18A processes a lot of sound sources, such as DVD, CD,AM/FM radio, and TV sound into spacious sound of natural surround by eala technology. Also even if there is a small speaker system, NJU26040-18A make rich sound with LPC technology. The applications of NJU26040-18A are suitable for stereo outputs products such as DVD Receivers, AV Amplifiers, TV, radio-cassettes player or ordinary audio products such as small speakers system.
