LINK IN AND LINK OUT CONNECTORS
LINK OUTPUT - line level output linked from unit preamplifier. LINK INPUT - line
level input linked to device power amplifier. Please note that LINK IN and LINK
OUT are designed before the equalizer and master potentiometer, so equal-izer
and master don' t affect audio in these connectors. LINK IN and LINK OUT
connectors are suitable to link audio signal from MMA to another amplifier or to
audio recorded etc. Please check block diagram to find location where connec
tors are inserted to amplifiers layout.
