CPB150 PowerBlock 150 Watt Stereo Guitar Amplifier

The Rear Panel:

9.SPEAKER OUTPUTS: Use these jacks to connect the amplifier to your speaker cabi- nets. Observe the wattage and impedance rat- ings adjacent to each jack. The Mono output is to be used when the Bridge Mono switch (#10) is depressed. The Right and Left jacks are to be used when running the amplifier in the stereo mode.

NOTE: Do not operate the unit with stereo cabinets that have a common shield. Operating the unit with this type of cabinet will activate the protection circuitry caus- ing the unit to shut down.

10.BRIDGE MONO: This switch, when depressed, sends the left channel to both power amplifiers and their outputs to the Mono Speaker Output jack (#9). When this switch is in the out position, the amplifier is in the stereo mode and the left and right signals are sent to the Left and Right Speaker Output jacks (#9).

11.LEVEL: Use this control to adjust the level of the signal at the Line Out jack (#12).

12.LINE OUT: Use this balanced XLR jack to send a line level signal to another amplifier, the house mixing board, or a recording console. (The signal at the Line Out jack is enhanced by the speaker simulator circuitry for superior sound.)

13.CD INPUT: Use these RCA jacks to con- nect the outputs of a CD (or MP3) player to the amplifier. The level of the signal into these jacks must be controlled by the source.

14.LINE IN RIGHT / LEFT/MONO / EFFECTS LOOP SND/RTN: Use these jacks to perform the following: (1) Send a line level signal into the amplifier for processing – for stereo sig- nals, use both jacks; for a mono signal, use the “Left/Mono” jack. (2) Connect an external effects device to the amplifier by means of a 1/4” T/R/S Y-cord inserted into the Effects Loop Snd/Rtn jack. (See page 6 for additional infor- mation.) These jacks are post eq, post Level.

15.POWER: Use this switch to turn the ampli- fier on (top of the switch depressed) and off (bottom of the switch depressed).

16.AC LINE IN: Connect the AC power cord securely into this jack. The grounded power cord should only be plugged into a grounded power outlet that meets all applicable electri- cal codes and is compatible with the voltage, power and frequency requirements stated on the rear panel. Do not attempt to defeat the safety ground connection!
