The patented, gold-plated Solid Cinch™ speaker
binding posts will also accept banana plug connec-
tions. Push the banana plug into the opening at the top
of the binding post.
Single Amplifier Connection
The XCS1.5K has three pairs of Input Terminals
labeled BASS, MID, and HIGH. If a single amplifier
is to be used to power the XCS1.5K, connect the
single amplifier to one pair of Input Terminals and the
supplied Jumper Cables can be used to connect the
remaining two pairs of Input Terminals. Attach the
Spade Terminals of the Jumper Cables as described
above in Loudspeaker Input Terminal Connection. Use
Jumpers to connect Negative Terminals to Negative
Terminals and Positive to Positive. In the end, the
pair of Input Terminals with the amplifier connected
should be daisy chained to the remaining terminals
that do not have an amplifier attached. Be careful to
observe correct polarity.
Never connect an input pair
with an amplifier attached to another pair with
another amplifier attached.
Multiple Amplifier Connections
The XCS1.5K Speaker can be powered by up to
three separate power amplifiers. To use three power
amplifiers, follow the instructions “Loudspeaker Input
Terminal Connection” above for each pair of cables
from each power amplifier to each of the three pairs of
terminals on the XCS1.5K (HIGH, MID and BASS).
Do not use jumper cables
, and always take care to
observe proper polarity.
To power the XCS1.5K with two amplifiers, connect
each power amp to a separate pair of terminals. Use a
pair of jumper cables to connect the shared terminals.
Typically, one amplifier would power the BASS, and
the HIGH and MID terminals would be powered by a
separate power amplifier with jumpers connecting the
pairs. It does not matter which pair of the jumpered
terminals you choose to connect to the Power
Amplifier.
Less Resistance
The XCS1.5K is an 8 Ohm speaker, and this is the
recommended connection from an amplifier. Some
people will use a 4 Ohm connection from an amplifier
as a kind of equalization. For instance, using a 4 Ohm
connection on the HIGH will result in a 3db drop in
that range. Bass can be lowered in the same manner
for use in a boomy room. If this is something you wish
to play around with, just remember to NEVER use a
higher Ohm output of an amplifier such as 16 Ohm.
This will result in heat generation beyond the ampli-
fier’s design.
