How to Connect using Three Amplifiers

Caution: The AC Power Cord should not be connected
to the Power Amplifiers until after the Loud-
speaker Connections have been made. Failure
to observe this could result in Electric Shock.
When connecting the XCS200 Loudspeaker to ampli-
fiers, it is very important to use cables of adequate
size so there is negligible 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:
Loudspeaker Cable Distance vs Wire Gauge Guide
25 feet 50 feet
Loudspeaker
(7.62 meters) (15.24 meters)
Impedance
or less or less
16AWG 14AWG
8 Ohms
1. Prepare Loudspeaker cables by choosing one of the
methods below:
Bare wire cable ends:
Carefully remove sufficient insulation from the
cable ends, refer to figures 30, 31 & 32. If the
cable is
stranded,
carefully
twist the
Figure 31
strands Figure 30
together
as tightly as possible.
Note: If desired, the twisted ends can be tinned
with solder to keep the strands together or
attach spade lugs.
Spade lug or prepared wire connection:
Insert the spade lug connector or prepared
section of the cable end into the terminal 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 33, 34
& 35.
