Output T
erminals
1.
Expose the end of the speak
er wir
es
by about 10 mm and twist using
nippers or a cutter
.
2.
Attach lugs to speak
er wir
e ends.
Lugs not supplied.
•
Use pliers,
etc.,
to crimp lugs to wires.
3.
Connect the speak
er wir
es to the
speak
er output terminals.
•
Fix the speak
er wires securely with the termi-
nal scre
ws.

The speak
er output mode can be tw
o-chan-
nel (stereo),
one-channel (mono),
or three-
channel ( mono). Connect the
speak
er leads to suit the mode according to
figures on the follo
wing pages.
•
When connecting to the speak
er input,
do not
connect the RCA output.

When connecting to the RCA input,

The po
wer amplif
ier is basically a tw
o-
channel/one-channel bridgeable amplif
ier
,
b
ut three channels can be achie
v
ed by
combining the stereo and mono modes
using inductors and capacitors.

•
Inductors (L1 and L2 in the diagrams)
act as lo
w-pass f
ilters. Capacitors (C1
and C2 in the diagrams) act as high-pass
filters. Inductors (L) are used for the
w
oofer/sub-w
oofer
,
and capacitors (C)
are used for the high/mid-high.
•
Remember when bridging an amplif
ier it
will see only half of the original speak
er
impedance. Therefore,
you
must
use
speak
ers that ha
v
e ratings of 4 ohms or
higher
. If you use speak
ers that ha
v
e
lo
wer impedance ratings it may cause
damage to the amplif
ier
.
•
W
hen the inductors and capacitors are
connected to the speak
er wires,
secure or
solder them so the
y cannot be pulled
loose.
T
ape or use heat shrink on the
joints to pre
v
ent short circuits.
