PS Audio C250 quick start Quick Start Guide

Quick Start Guide

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!!
