PS Audio C250 User Manual

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 dedicated 

per speaker, the 

left and right desig-

nations on the back of the C250 can be 

substituted for “high” and “low” (or what-

ever correlates to the description your 

speakers use to differentiate between high 

frequency and low frequency inputs).  With 

two mono C250s per speaker, one ampli-

fier would be used for low frequencies 

while the other would be used for the high 

frequency connection to your speaker.  

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 

incorporate the 

C250 into other 

types of auto-

mated systems.  

This 12-volt trigger 

is an input trigger 

and will respond to 

an external 12-volt 

signal.
