NJM2189
SPEAKER ELEVATION AUDIO PROCESSOR with A/V Focus Filter
s GENERAL DESCRIPTION The NJM2189 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 NJM2189 includes the A/V Focus Filter to reduce harsh sound when speakers are directly put on hard-surface floor. The Bypass and Focus Mode inputs are separate to be the same sound volume in both Bypass and Focus mode. The NJM2189 is suitable for almost all car audio, Projection TV, radio cassette, and then. s PACKAGE OUTLINE
