D-POWER SAFETY SERIES 7. Lightning For added protection of this amplifier during lightning storms or when it is left unattended and unused for long periods of time, unplug it from the wall outlet. This will prevent damage to the amplifier due to lightning and power-line surges. Disconnection from the mains power supply can only be achieved by removing the plug from the mains socket and by external disconnecting all poles from the mains. 8.

D-POWER 2 FACILITIES SERIES 2.3 Factory Settings D-POWER amplifiers are delivered with the following factory settings Front panel: Rear panel: 7 8 Volume Control Channel A Volume Control Channel B The volume is set to minimum. The volume is set to minimum. 11 On/Off Switch The amplifier is switched off.
D-POWER 3 INSTALLATION SERIES 3.1 Mains Supply When mounting or connecting the amp always disconnect it from mains. Only connect the D-POWER amplifier to an appropriate AC circuit and outlet, according to the requirements indicated in the second line on the rating plate. 3.2 On/Off Switch The On/Off Switch is a rocker-type switch. It is located on the right side of the front panel. To turn the amplifier on, press on the upper part of the switch.
D-POWER 7,5 mm 3.3 Mounting Use four screws and washers when mounting the amplifier to the front rack rails. For mobile use, the amplifier should also be secured using the 19” mounting elements on the rear panel. 10,5 mm 88,1 mm 76,2 mm 3 INSTALLATION SERIES If this cannot be achieved a forced ventilation system has to be used. 3.5 Ground Lift The input signal ground (pin 1 for all 4 XLRs) is connected to the ground of the mains supply.
D-POWER 3 INSTALLATION SERIES 3.6 Mode Selector The switch on the rear panel changes the operating mode. 3.6.1 Stereo Operation, Two Channel Operation Two fully independent amplifier channels (normal operating mode). WARNING! Always turn off the amplifier before making changes on the Mode Selector. D-POWER A Z ≥ *Zmin When the amplifier is switched on again, the selected mode will operate. B Z ≥ *Zmin 3.6.2 Parallel-Mono Operation Parallel operation of the two channels together.
D-POWER 3 INSTALLATION SERIES 3.6.3 Mono-Bridge Operation One-channel mono bridged operation. 3.7 Wiring 3.7.1 XLR Connection XLR: Pin 1 = Ground (or lifted via 15 Ω 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. D-POWER A Z ≥ 2 *Zmin The second amplifier channel processes the same input signal, but with reversed phase.
D-POWER 3 INSTALLATION SERIES 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: WARNING ! SPEAKON connectors marked with the lightning flash indicate high vol tages that are potentially life threatening.
D-POWER 4 OPERATION SERIES 4.1 Controls 4.1.1 Volume Control A volume control with 41 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. 4.1.
D-POWER 4 OPERATION SERIES 4.1.5 High Pass Filter Slope: 12 dB/octave Type: Butterworth 4.2 Indicators 4.2.1 On LEDs Under normal operation, after the amp has started, the green power LEDs are permanently lit. (Channel A as example) Left position: HPF: Off Middle position: HPF: 30 Hz Right position: HPF: 50 Hz HPF OFF HPF 30 Hz HPF 50 Hz Low frequency response curves P. 17 USER MANUAL D - P O W E R SERIES 4.2.
D-POWER 4 OPERATION SERIES 4.2.3 I-Out LEDs The brightness is proportional to the output current in the corresponding channel. 4.2.4 Clip LEDs This LED indicates an overloading of the amplifier when the power output level is too high. 4.2.5 Mode Indicators On the front panel there are two yellow LEDs to indicate the mode that is set. In stereo mode (2-channel) none of them will be lit. In Parallel-Mono the (PM) LED will be lit and in Mono-Bridge, the (MB) LED will be lit.
D-POWER 4 OPERATION SERIES 4.3 Power Amp Protection Systems 4.3.1 Clip Limiter If the power amp is overdriven, the clip detection triggers the Attack-ReleaseCircuit (ARC). The ARC delivers the control voltage for the gain reduction. Two different attack modes (fast and slow) can be selected with the Clip Limiter switch (see 4.1.4 Limiter Switch). 4.3.
D-POWER 4 OPERATION SERIES 4.4 Mains Protections 4.4.1 Inrush Current Limitation Within 2 seconds of the amplifier being switched on, the inrush current limiter will increase mains current from nearly zero to nominal value. This value depends on program material, output level and speaker loads. 4.4.2 Mains Over Voltage Detection Mains over voltage detection is always operative. When the mains voltage exceeds approx. 263 V (230 V operation) or 134 V (120 V operation), the amplifier will be switched off.
D-POWER 4 OPERATION SERIES 4.7 Filter Cleaning The air intake on the front of your D-POWER Amplifier is fitted with a removable filter system. If the filter becomes clogged, the unit will not cool as efficiently as it should and may result in reduced output levels. WARNING: Turn off the amplifier before removing the front frame. To clean or replace the filter just slightly unscrew the fixing screw with the help of a 3 mm allen key.
D-POWER 4 OPERATION SERIES 4.8 Volume Control Security Cover (Accessory optional) It is possible to install a solid protection over the volume controls to prevent intentional or unintentional changes of the amplifier volume settings. 1 The GAIN-POT-COV package contains: - Volume Control Security Cover (1) - Two fixing screws (2) - Jig (3) - Tech Note with informations about mounting the Volume Control Security Cover (not illustrated) Please contact CAMCO or your dealer/distributor for more details.
