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.

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 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.
