[. . . ] D-POWER SERIES D-POWER SERIES USER MANUAL INFORMATION FOR USE FOR MODELS D-POWER 2, D-POWER 3 and D-POWER 4 DUM_GB_200-R2_09-200 © Copyright 200 by CAMCO Produktions- und Vertriebs-GmbH für Beschallungs- und Beleuchtungsanlagen Fischpicke 5, D-57482 Wenden, Germany Telephone +49 (0) 2762 408-0 D-POWER SERIES P. 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. Reselling of the amplifier is only possible if the user manual is available. [. . . ] This mode is useful when, for example, three identical loudspeakers are to be operated with the same power. P. 3 USER MANUAL D - P O W E R SERIES D-POWER SERIES 3 INSTALLATION 3. 6. 3 Mono-Bridge Operation One-channel mono bridged operation. D-POWER 3. 7 Wiring 3. 7. 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. 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. To prevent electric shock, do not operate the amplifier with any of the conductor portion of the speaker wire exposed. Channel A Channel A Channel B Channel B Channel B Channel B Channel A Channel A signal ground signal ground signal ground signal ground SPEAKON right Pin + Pin Pin 2+ Pin 2- Input Channel A NOTE: For reasons of safety and performance, use only high-quality fully insulated speaker cables of stranded copper wire. Use the largest wire size that is economically and physically practical, and make sure the cables are no longer than necessary. Input Channel B IMPORTANT: When connecting speaker cabinets in parallel, always use all the contacts in both SPEAKON connectors. If not, this may cause permanent damage to the connectors and considerably reduce performance. SPEAKON left P. 5 USER MANUAL D - P O W E R SERIES D-POWER SERIES 4 OPERATION 4. Volume Control A volume control with 4 notched settings controls the audio signal. These settings have been selected to correspond to human hearing characteristics (logarithmically) and therefore guarantee an optimal range of settings for practical applications. Each channel can be set individually except when operating in mono modes whereby only channel A is active. 4. . 3 Gain and Input Sensitivity The table shows input sensitivity per channel for a given gain and load.

(See 4. 3. 1 Clip Limiter) Set the volume to zero before turning on the amplifier to prevent the occurrence of sudden high volume levels which may cause damage to your hearing and/or the speakers.
