  • Page 3: Introduction

    It’s rugged construction and low profile make it ideal for sustaining the abuses of the road with reliability and space-saving economy. The pm1400 is rated at 700 watts per channel into 4 ohms and 475 watts per channel into 8 ohms. In bridged mono operation it is rated at 1400 watts into 8 ohms.

    Level controls can be bypassed. See back panel for Level Defeat Switch. Note: A precision attenuator is available as an option for the pm1400, which can be installed inside the amplifier (see page 11). Contact your Carver Professional Dealer for details.

  • Page 8: Installation

    When several amplifiers are mounted together in a rack, you may need to provide air inlets from the outside of the rack. The pm1400 is fan cooled. The fan is internally mounted so that it draws air in from the front and exhausts it out the rear.

  • Page 9: Magnetic Leakage Considerations

    AC Power Considerations Ensure that the pm1400 is plugged into an outlet capable of supplying the correct voltage specified for your model and enough current to allow full-power operation of all the amplifiers plugged into it. The current demand of a power amplifier varies depending on several factors, including the impedance of the load, the output level of the amplifier, and the crest factor and duty cycle of the program material.

  • Page 10: Output Wiring

    Output Wiring (see your Carver Professional Dealer for information on Carver Professional Accessories) Use heavy gauge wire for speaker connections. The greater the distance between the amplifier and the speakers, the larger the diameter the wire should be to minimize power losses across the wire and improve the damping of the speaker.

  • Page 11: 70V Distribution Systems

    As with all 70-volt systems, transformers are still required at each loudspeaker. The pm1400 can deliver 475 watts per channel into an 8 ohm impedance (61.6V line voltage). The price for going direct is having to calculate the new transformer tap values at the new line voltage. Since watts are proportional to the square of the voltage, compute the correction factor by taking the ratio of the square of the line voltages.

    STEREO/MONO SWITCH Figure 8 Servicing Instructions CAUTION: To reduce the risk of electric shock, do not perform any servicing other than that contained in the Operating Instructions unless you are qualified to do so. Refer all servicing to qualified service personnel. To remove the input panel and input board: 1.

    Input Polarity The XLR input connectors on the pm1400 are shipped from the factory with pin 2 hot (+), as indicated on the rear panel. The polarity of the balanced inputs can be reversed by changing four jumpers located on the Input Board. Cross-wire JP3 and JP4 to change the input polarity of CH 1 and cross-wire JP1 and JP2 to change CH2 (see Figure 8).

  • Page 16: Care And Service Assistance

    Assistance C a re: Wipe off the pm1400’s front panel and chassis from time to time with a soft, dry cloth. If you have something stubborn to remove, use a mild dish soap or detergent sparingly applied to a soft cloth. Don’t use alcohol, ammonia, or other strong solvents.
