    This is infinitely preferable to breaking the ground pin off the power cord. The pt1250’s XLR connector uses the American wiring convention (pin 3 hot). Note that the pin 3 of the XLR connector cor r esponds to the tip connection on the TRS phone jack . All input connectors are connected in parallel; you can parallel the amplifier inputs by patch ...

    70V Distribution Systems The pt1250 has sufficient output voltage capability in stereo mode to drive 70-volt distribution systems without using a step-up transformer at the amplifier . The amplifier delivers 300-watts per channel to the 70-volt system. T ransformers are still required at each loudspeaker (as is the case with all 70-volt systems). B ...

    15 AC Power Considerations Ensure that the pt1800/pt2400 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, ...

    This will insure that the resistance of the speaker wire is less than 5% of 4 ohms, resulting in a transmission loss of less than 0.5 dB. The multi-way binding posts can accept spade lug, bare wire or banana connections. Be sure that all the fine strands of the wire are twisted together and contained within the connector. If even one strand is loos ...

    CAUTION: In bridged mono operation, the output connections are actually a balanced output configuration. This means that both output terminals have voltage present (neither one may be grounded). 70 V olt Distribution Systems The pt2400/pt1800 have the capability of driving a 70 volt distribution system directly without the need for step up transfor ...

    Fig. 3 shows a typical set up in a 3 rack with 3 amplifiers. In this case the top amplifier is the master amplifier. Its channel 1 power switch controls the power up and power down sequence for the whole rack and possibly additional racks. Channel 2 may be used as an optional backup for channel 1. All other amplifiers have power switches turned off ...

    Distortion Distortion is usually caused by excessive loss in the input controls (the mixer/equalizer/crossover can’t produce enough output), overdriving resulting in output clipping, or current limiting caused by excessively low load impedances. 1. Check the setting of the Input Level controls. If set too low, the preceding piece of equipment may ...
