CONNECTION: Amplifier output line con-
nection is made to the screw terminals
which are designed with wire retainers for
insured reliability. Input terminals are
numbered (#1 and #2) to maintain system
phasing. (#2 is the positive terminal). The
wide and narrow slots adjacent to #1 and
#2 are used for cable strain relief.
