Stereo Output: The positive terminals
are indicated by a red connector and (+).
The negative terminals are indicated by a
black connector and (-). Connect the left
positive (red) of the C250 to the positive
(red or +) of your left speaker cable and
connect the left negative (black) of the
C250 to the negative (black, white or -) of
your left speaker cable. Do the same for
the right side terminals of the C250 and
your right speaker. Be sure to hook-up
your speaker(s) in phase with the C250; it
should be positive to positive and negative
to negative.
Mono Output: Hooking up a speaker to a
C250 set for mono is slightly different. As
with the input connectors, follow the red
text to determine the appropriate connec-
tions.
In mono, the positive lead is established
with the (+) from the left channel and the
negative lead comes from the (+) on the
right channel. Either the top or bottom
connectors can be used, once again for
easier bi-wire hook-up.
Other: Aside from standard stereo or
mono applications, the C250 can also be
applied in bi-wiring or bi-amping configu-
rations. To bi-wire, simply add a second
set of speaker cables to the second set
of output binding posts and hook-up your
speakers according to that manufacturer’s
recommendation.
For bi-amping, you may use one C250 (in
stereo) or two C250s
(in mono) to drive each
of your speakers. With
one stereo C250 dedi-
cated per speaker, the
left and right designa-
tions on the back of the
C250 can be substitut-
ed for “high” and “low”
(or whatever correlates
to the description your
speakers use to differ-
entiate between high frequency and low
frequency inputs). With two mono C250s
per speaker, one amplifier would be used
for low frequencies while the other would
be used for the high frequency connection
to your speaker.
Back Panel: Communication
The C250 includes the PS Buss, which
allows for a sophisticated method of com-
munication between PS gear that supports
this protocol. Each PS product that has
the PS buss installed can communicate
with any other similarly equipped PS prod-
uct.
The PS buss allows you to turn on and off
the C250 from another PS component that
is set as the master device.
To place the C250 on a network, you will
need to have it connected to another piece
of PS equipment that is properly interfaced
to a CE network.
The C250 can be assigned as single or as
one of many power amps in the system.
You can sequentially turn the unit on or off
from the push of a single button.
Also included on the back of the C250 is a
12-volt DC trigger. This device has been
provided for your convenience to incorpo-
rate the C250 into other types of automat-
ed systems. This 12-volt trigger is an input
trigger and will respond to an external
signal from 5-12 volts.
Back Panel: Power
The C250 is equipped with
the standard, internation-
ally accepted 15 amp IEC.
This device is labeled, “AC
input.” With the supplied
power cord, or with an-
other high-end after mar-
ket cable like the PS Audio
Lab Cable II, connect the
C250 to a power source.
