NJM2184
SPEAKER ELEVATION AUDIO PROCESSOR with A/V Focus Filter
s GENERAL DESCRIPTION s PACKAGE OUTLINE The NJM2184 is a speaker elevation audio processor with A/V Focus Filter, based on SRS Focus technology. It is capable of raising sound image. In addition, the NJM2184 includes the A/V Focus Filter to reduce harsh sound when the speakers are directly put on hard-surface floor. The NJM2184 is suitable for almost all car audio, Projection TV, radio cassette, and then. NJM2184L
s FEATURES qOperating Voltage (4.7 to 13V) qLow Operating Current (7.0mA typ.) qLow Output Noise (15Vrms typ.) qAdjusted by LF Elevation, HF Elevation, and Bass Compensation Volume qInternal A/V Focus Filter qBipolar Technology qPackage Outline SDIP28,SDMP30
