Caution: The AC Power Cord should not be connected to
the Amplifier until after the Loudspeaker Con-
nections have been made. Failure to observe
this could result in Electric Shock.

When connecting a XR50 Loudspeaker to an ampli-
fier 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 (Ameri-
can Wire Gauge). The smaller the Gauge number, the
larger the wire size:

4. Prepare Loudspeaker cables by choosing one of the
methods below:
Bare wire cable ends:
Carefully remove sufficient insulation from
Carefully remove sufficient insulation from
the cable ends, refer to figures 12, 13 & 14. If
the cable is
stranded, care-
fully twist the
strands together
as tightly as
possible.

Notes: 1. If desired, the twisted ends can be tinned
with solder to keep the strands together.
2. The prepared bare wire cable ends may be
inserted into spade lug connectors.

tration on the next page, connect the
Loudspeaker hookup cables with ba-
nana plugs into the hole
at the end of the terminal
to the XR50 Negative (-)
Input Terminal and Posi-
tive (+) Input Terminal

Note: It is important to maintain the correct polar-
ity at both ends of the Loudspeaker cables.
8. Connect the other end of Loudspeaker cables com-
ing from the XR50 Negative (-) Input Terminal to
the Left Channel COM (-) Output Terminal of the
Amplifier.
