PS Audio C250 사용자 설명서

1.  Turn off your pre-amplifier or any other 

piece of equipment to which the C250 will 

be connected.

2.  Ensure that you have a proper pair of 

audio interconnects for the input signal 

and a pair of speaker cables to connect 

the C250 to your speakers.

3.  Unpack the C250 and place it on a 

smooth surface.  (As with any amplifier it 

is not advisable to place on carpet or other 

airflow restricting materials.)

4a.  Stereo Input:  Choose either the 

single-ended (RCA) or balanced (XLR) 

input connections on the 

back of the C250.  There 

is a selector switch for 

each channel to activate 

the connector you have 

chosen.  Only one type 

of input, RCA or XLR, will 

work at a time.  Be sure 

to set both the left and 

right channel to either 

RCA or XLR input.  

4b.  Mono Input:  Follow 

the red text on the back 

of the C250 for mono setup.  Set the rear 

panel selector switch on the back panel to 

“Mono.”  This deactivates the right channel 

input connectors.  Use the left channel in-

put connectors to run your C250 in mono.  

Don’t forget to set this input for RCA or 

XLR.

5.  Connect the outputs of your pre-ampli-

fier or source equipment to the inputs of 

the C250 according to the instructions in 

4a for stereo or 4b for mono.

6a.  Stereo Output:  Connect your speak-

ers to the C250’s output terminals, labeled 

“Right” and “Left.”  Be sure to connect the 

polarity of the speaker cables correctly.  

Match the C250’s positive (red) and nega-

tive (black) terminals to the corresponding 

speaker connections.  

6b.  Mono Output:  To connect the C250 to 

your speaker when in mono mode, follow 

the red text on the back panel.  Connect 

your speakers’ positive lead to the left 

channel (+) and the negative lead to the 

right channel (+).  

7.  Locate the power cord supplied with 

the C250 and plug it into the connection 

labeled “AC Input.”  The Classic 250 has 

an auto-sensing input voltage circuit, so 

the C250 is virtually plug-and-play in this 

regard.  For more information on input AC 

voltage, see pages 7.

8.  Plug the male end of 

the power cord into your 

wall receptacle.  This 

automatically engages 

the regenerator and 

voltage gain stage.  The 

meter display will light 

up in yellow for a period 

of 17 seconds during 

this intial activation 

phase.  The Power but-

ton is purposefully kept 

inactive during this time.

9.  After 17 seconds and the meter display 

has gone dim, turn on the C250 by press-

ing the button in the center of the chassis, 

below the meter display.  Also, turn on the 

pre-amplifier and any other piece of equip-

ment needed to operate your system.

10.  The C250 will power up in standby 

mode for 40 seconds.  During this period, 

the front panel meter will light up in yel-

low and the PS logo in blue, indicating the 

standby mode.

11.  After 40 seconds the meter will light up 

in blue.  The C250 is now fully operational 

and ready to drive your speakers.  Start 

the music and enjoy!!
