M61509FP
TONE CONTROL/VOLUME CONTROL
DESCRIPTION
The M61509FP is the sound controller powered by the "QXpander" system. The "QXpander" system produces normal and wide 3D sound expansion from any stereo input signal.
(Note) This device is produced under license from QSound Lab,Inc.(Canada) .
FEATURES
