How to Connect for Mono Parallel
into the ter-
minal side
access hole,
and tighten
the terminal
cap until
the cable is firmly clamped into the terminal so the
wires cannot slip out. Refer to figures 4, 5 & 6.
Banana plug connection:
Insert the banana plug into the hole
at the top of the terminal. Refer to
figure 7.
Note: Banana Plugs are for use
in the United States and
Canada only.
2. Connect the loudspeaker hookup
cables to the output terminals that match the imped-
ance of your loudspeakers, being careful to observe the
correct polarities. Refer to the Mono (Parallel) Hookup
Connections Chart below.
3. Connect the MC275 Power Cord to a live AC outlet.
Caution: The supplied AC Power Cord should not be
connected to the Rear Panel of the MC275
Amplifier until after the Loudspeaker Connec-
tions have been made.
When connecting Loudspeakers to the MC275 it is very
important to use cables of adequate size, so there is little to
no power loss in the cables. The size is specified in Gauge
Numbers or AWG (American Wire Gauge). The smaller
the Gauge number, the larger the wire size:
If your loudspeaker cables are 50 feet (38.1m) or less,
use at least 14 Gauge.
If your loudspeaker cables are 100 feet (76.2m) or less,
use at least 12 Gauge.
1. Prepare the Loudspeaker Hookup Cable and Jumper
Wires for connection to the Power Amplifier Output
Terminals; two 5-1/4 inch (13.34 cm) Jumper Wires
and one Loudspeaker Hookup Cable cut to the desired
length. Prepare the cable and wires by choosing one of
the methods below:
Bare wire cable ends:
Carefully remove sufficient insulation from the cable
ends, refer to
figures 1, 2 &
3. If the cable
is stranded,
carefully
twist the
strands together as tightly as possible.
Note: If desired, the twisted ends can be tinned with
solder to keep the strands together,
or attach spade lug and/or banana
connector.
Spade lug or prepared wire con-
nection:
Insert the spade lug connector or
prepared section of the cable end
