USER MANUAL D - P O W E R SERIES D-POWER SERIES IMPORTANT SAFETY INSTRUCTIONS IMPORTANT SAFETY INSTRUCTIONS ) Read the information for use (user manual). 2) Please keep this user manual in a safe place during the lifetime of the amplifier. The user manual forms an integral part of the amplifier. [. . . ] When the amplifier is switched on again, the selected mode will operate. 3. 6. Stereo Operation, Two Channel Operation Two fully independent amplifier channels (normal operating mode). D-POWER A Z *Zmin B Z *Zmin 3. 6. 2 Parallel-Mono Operation Parallel operation of the two channels together. D-POWER Zres 0. 5 *Zmin A The output terminals of the two channels are configured in parallel using an internal relay. The (single) load is connected either to the output of channel A or to that of channel B (as if in stereo). While the total output of the amplifier remains the same and the output voltage level is also the same as in stereo operation, the minimum impedance that can be connected is reduced by half due to the fact that current capability is doubled. The channel B-Input is inactive ­ turn the volume of channel B down to zero. This mode is useful when, for example, three identical loudspeakers are to be operated with the same power.

XLR Connection XLR: Pin = Ground (or lifted via 5 resistor) (See 3. 5 Ground Lift) Pin 2 = Hot (inphase) Pin 3 = Cold (out of phase) Always use symmetrical (balanced) shielded cable to connect the amplifier. Z 2 *Zmin Input Channel B Input Channel A LINK B LINK A A The second amplifier channel processes the same input signal, but with reversed phase. The (single) load is connected between the two positive channel outputs using a suitable connected SPEAKON connector. While the total output of the amplifier remains the same, both the available output voltage and the minimum impedance that can be connected are doubled, as compared with stereo operation. A signal feeding channel B will have no effect on the output. Turn the volume of channel B down to zero. In Mono-Bridge mode RMS output voltages are as high as 230 V. Wiring to the speaker loads must conform to NEC Class 3 safety standards or its equivalent that meets all national and local electric codes. All customer specific cables may only be manufactured by qualified suppliers/personnel. All cabling or rewiring work must be carried out by qualified personnel. * Zmin = 4 for D-POWER 2, 3 and 4 2 3 2 3 3 2 3 2 To Channel B To Channel A Input Ground Lift Input Ground Lift in position: grounded ALWAYS SWITCH OFF THE AMPLIFIER BEFORE CHANGING MODES P. 4 USER MANUAL D - P O W E R SERIES D-POWER SERIES 3 INSTALLATION 3. 7. 2 SPEAKON Connection Both SPEAKON connectors are connected to channel A and channel B outputs. The pin configuration of the SPEAKON connectors is as follows: SPEAKON right: Pin + (View at the back) Pin Pin 2+ Pin 2SPEAKON left: (View at the back) WARNING !SPEAKON connectors marked with the lightning flash indicate high voltages that are potentially life threatening. Wiring to these terminals requires installation by an instructed person or the use of ready-made leads or cords. Custom wiring should only be made by qualified personnel.
