2.2 The Amplifier

The D-POWER 7 is a Class-H power amplifier with a power output of:

•3 kW per channel @ 2 Ω

•6 kW in Mono Bridge @ 4 Ω

•6 kW in Parallel Mono @ 1 Ω

The D-POWER 7 power amplifier is fitted with Switched Mode Power Supply (SMPS), which significantly reduces the weight and size (only 2U). Using SMPS, the 3 symmetrical supply voltages of the power amplifier are more stable than the power supplies used in conventional amplifiers.

2 THE AMPLIFIER

The D-POWER 7 also uses a microprocessor for controlling and monitoring the power amp. This has four main advantages over more traditional power amp systems:

Reduced Distortion Improved Noise Characteristics Indication of Protection or Failures by different LED sequences

D-POWER

SERIES

The D-POWER 7 has been designed as an intelligent and powerful amplifier for performing specialised tasks within a complex audio system. Users can adapt the power amp to meet their specific audio requirements before use. Controls mounted on the front and the rear of the D-POWER 7 allow the different functions to be accessed. Since some of the externally mounted controls have multiple functions, it is important that users should familiarise themselves thoroughly with the entire range of controls and programmable features before using the power amp.

If you have any questions regarding features and/or functions of your D-POWER 7, CAMCO will be pleased to offer you further information. Alter- natively, contact your dealer or distributor.

NOTE: Even under normal conditions the mains current can reach levels up to 60 A (230 V), 120 A (120 V) and 140 A (100 V), respectively; this could cause lamps to flicker if connected to the same mains as the amp. The impedance of the AC circuit should be less than 0,157 Ohms to avoid flicker according to EN61000-3-11 “Electromagnetic compatibility – Part 3-11: Limits – Limitation of voltage changes, voltage fluctuations and flicker in the public low-voltage supply systems – Equipment with rated current

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. During power up the Clip and Signal LEDs from both channels will light up in red for a few seconds. To turn the amplifier off, press on the lower part of the switch.

3 INSTALLATION

Amplifier is switched on Amplifier is switched off

NOTE: This switch does NOT disconnect the amplifier from mains. Make sure the mains power socket or an alternative disconnect device is nearby and easily accessible.

The switch initiates start-up by activating the inrush current limiter. As soon as the power amplifier is connected to the mains power supply, a vol tage is supplied to both the line-filter and the fused input of the controllable rectifier. Disconnecting the amplifier from the main power supply can only be achieved by physically separating the amplifier from the mains by pulling the mains plug. The mains plug therefore has to be freely accessible. Disconnect the mains plug from the mains during a lightning storm or when the amplifier remains unused or unsupervised for a prolonged period of time. Alternatively, you can disconnect the amplifier via an external all-pole disconnection from the mains. If a power cut occurs while the amplifier is switched on, it will restart automati cally once the power supply has been restored. All amplifier settings prior to the loss of power will be maintained.

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.

3.4 Cooling

Under normal operation of the power amp, overheating should never be a problem. The air is taken in from the front and out through the back. It is of course essential that while the power amp is running air is able to circulate around it freely. The efficiency of the cooling will depend on the immediate environment (e.g. an enclosed rack, direct sunlight) and on whether the front filter is clogged. If the amp is installed in a case, the open area at the back of the case must be at least 140 cm². This area should be in line with the amp. If this can not be achived 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. In order to avoid ground loops, this connection can be separated via a resistor. The ground potential of the power amp and the ground of the loudspeaker always remain connected to the ground of the mains supply regardless of the setting of this switch.

To prevent electric shock, do not operate the amplifier with any of the conductor portion of the speaker wire exposed.

NOTE: For reasons of safety and performance, use only high-quality fully insu lated 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.

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.

3 INSTALLATION / 4 OPERATION

4.1 Controls

4.1.1 Volume Control

A microprocessor-controlled DCA (Digital Controlled Attenuator) with a control resolution of 12 bits per channel is integrated into the signal path. This means that the signal is not subject to an A/D followed by a D/A conversion with associated losses and delay. Using a DCA instead of the “conventional” VCA significantly reduces distortion and, at the same time, it improves the noise characteristics. A volume control with 41 notched settings controls the DCA via a microchip. These settings have been selected to correspond to human hearing characteristics 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.

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.

4.2 Indicators

4.2.1 On LEDs (multifunctional)

Under normal operation, after the amp has started, the green On LEDs are permanently lit. A variety of different sequences of flashing LEDs are used to indicate other operating states and errors in the relevant channels of the power amp (See 6.1 Flashing sequences for On LEDs).

4 OPERATION

4.2.2 Signal LEDs

The green Signal LED is illuminated when the voltage level at the output reaches approx. 4 V; this corresponds to a power of approx. 4 W over a 4 Ohm resistor.

4.2.3 I-Out LEDs

The brightness is proportional to the output current in the corresponding channel.

4.2.4 Clip LEDs (multifunctional)

The colour of the bi-coloured LED changes between orange and red, depending on the clip intensity. Orange indicates light clipping, red indicates heavy clipping.

4.3 Power Amp Protection Systems

4.3.1 Clip Limiter

If the power amp is overdriven, the clip detection circuit triggers the microprocessor. The processor reduces input signal level by controlling the DCA. The strategy is implemented in software. For sinusoidal input signals the microprocessor limits the input signal in such a way that non-linear distortions of the signal never exceed 1 %. The Clip Limiter can work on each channel independently (except in the two mono operation modes). (To disable the Clip Limiter, see 4.1.4 Limiter

Switch.)

4.3.2 Under Impedance Limiter

As a result of incorrectly connected or defective loads, under impedance or even short circuits may occur in one or both power amp channels. The microprocessor constantly calculates the load impedance at the output channels. If an impedance of less than 1,33 ohms/channel is detected, the microprocessor limits the signal to the power amp until a subsequent measure ment indicates that impedance has risen to a safe level. Whenever the Under Impedance Limiter is active, the corresponding channel’s On LED is turned off (See 5 Troubleshooting).

4.3.3 SOA Protection

To ensure that the power transistors are only used in the Safe Operation Area (SOA), the SOA-protection in stereo mode switches back the rail voltages of the respective power stage. In mono modes the rail voltages of both channels are switched back.

4.3.4 Speaker Protect Limiter

Whenever the SOA protection of the power amp switches back the current rail there could be a small clipping at the output; but the microprocessor is also triggered by this protection and will reduce the signal level immediately to minimise the effect. The user can decide either to use Speaker Protect or not. If you use this amp for low frequencies (bass / Sub bass) and you want to squeeze the absolute maximum out of it, Speaker Protect can be switched off. For all other appli cations (e.g. Full Range) it’s recommended to keep Speaker Protect switched on.

4.3.5 DC Protection

Each output of the power amp is constantly monitored for persistent DC voltage levels. If the 3 V threshold voltage is exceeded at any of the outputs, the main SMPS will shut down and the channel will be automatically switched off. The microprocessor performs a sophisticated strategy to locate the cause of the malfunction. DC can be located in the output stage, driver stage or at the input of the amplifier.

Output Stage

When a DC voltage is located at an output stage, the main SMPS remains

4 OPERATION

switched off. The On LEDs will show a flash sequence corresponding to this malfunction (See 5 Troubleshooting).

Driver Stage

When a DC voltage is located at the driver stage only the defective channel’s output stage and the DCA are muted. The other channel continues to work. The On LED of the defective channel will indicate the malfunction by starting the relevant flash sequence (See 5 Troubleshooting).

Amplifier Input

When DC is located at the input stage only the DCA of the affected channel is muted. The other channel continues to operate normally. If the DC signal at the input vanishes, the microprocessor will de-mute the affected channel and the amplifier will work as usual again.

4.3.6 DC Servo

To prevent DC Offset at the speaker output the D-POWER 7 is fitted with two DC Servos. (Hence there are no capacitors in the signal path)

4.3.7 Over Current Protection

The output stage is permanently monitored for possible current surges. There are two limiting levels of over current depending on output voltage. These limits will be set automatically. This improves reliability without degrading sound quality when driving complex loads.

4.3.8 Thermal Protection

The microprocessor uses several sensors in the amp in order to ascertain tem perature data. If the microprocessor detects a temperature of more than 85 °C at the heat sinks, the input signal on that channel is reduced. If the temperature exceeds 100 °C, the main SMPS is switched off. The On LED of the overheated channel will start a blinking-sequence (See 5 Troubleshooting).

4.4 Mains Protections

4.4.1 Inrush Current Limitation

Within 2 seconds of the D-POWER 7 being switched on, the inrush current limiter will increase mains current from nearly zero to nominal value. This value de pends 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. 267 V (230 V operation), 134 V (120 V operation) or 117 V (100 V operation), the amplifier will switch off. When the mains voltage returns to nominal value, a soft start occurs.

4.4.3 Mains Failure Detection

Mains Failure Detection is always operative. When the mains supply is interrupted for about 2 mains cycles, the amplifier will switch off. When the mains voltage returns to a normal value, a soft start occurs.

4.4.4 Fuse Protection

The average mains current can peak temporarily, depending on the load impedance and type of signal, at values several times higher than the nominal value allowed by the fuse protection. Continuous monitoring of the fuse protection status allows the conditions that would trigger the fuse protection to be predicted. In order to avoid shut-down of the amplifier due to current overload, the amplitude of the input signals will be limited. The limitation of the input signal allows a 6 kW D-POWER 7 power amplifier to be operated reliably from a mains power supply of 230 V/16 A (120 V/30 A; 100 V/30 A).

4.5 Main SMPS Protections

4.5.1 Over Current Protection

Main SMPS (Switched Mode Power Supply) transformer current of your D-POWER 7 is continuously monitored. If over current occurs, the main SMPS immediately stops working. Should there be an internal failure, this feature prevents other parts being damaged.

4.5.2 Thermal Protection

The temperature of the main SMPS transformer of your D-POWER 7 is

4 OPERATION

permanently monitored. If the temperature exceeds 85 °C, the microchip reduces the input signals of both channels. If the temperature surpasses 100 °C, the main SMPS is switched off. The On LEDs will start a blinking sequence corresponding to this malfunction (See 5 Troubleshooting).

4.6 Fans

The fans mounted in your D-POWER 7 operate permanently, but as long as the temperature remains below 40 °C, they run at their slowest speed and can hardly be heard. The highest detected temperature from either channel controls the speed of the fans. Above 40 °C the speed is increased until it reaches its maximum value.

4.7 Filter Cleaning

The air intake on the front of your D-POWER 7 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: Disconnect the amplifier from the mains before removing the front frame.

D-POWER

SERIES

To clean or replace the filter just slightly unscrew the fixing screw with the help of a 3 mm allen key. The screw will be held back by a small plastic spacer on the back of the frame to avoid losing it. Then shift the front frame slightly to the right. Then you should be able to remove the frame from the amplifier completely (pull gently to avoid any bending of the front frame).

5.1 On LED Flashing Sequences

When switching on the amp the On LEDs flash twice accompanied by a flash of Clip LEDs. This is normal for the ‘Start’ sequence of the D-POWER 7.

When switching off the amp the On LEDs flash several times followed by a flash of Clip LEDs. This is normal for the ‘Shut Down’ sequence of the D-POWER 7. (It is the same as the loss of the mains voltage.)

In the following table you will find the possible LED sequences of the On LEDs:

5 TROUBLESHOOTING

Indication: On LED(s) sequence

The amplifier is in protective muting. Refer to On LED flashing sequences table to find out the cause for the mute.

•Overheating will cause protective muting.

•If the fans aren’t running the amplifier requires servicing

D-POWER

SERIES

Indication: On LED(s) sequence

Please refer to the On LED flashing sequences table to find out which protection is active. High temperature will cause an attenuation of output level! DC will cause the amp to mute or shut down.

• If the On LED sequence indicates “DC, Input Signal Fault”, switch off the

D-POWER 7 and unplug the amp to disconnect it from the signal source. If the On LED shows the same sequence when the D-POWER 7 is switched on again, the amp will need to be serviced by a qualified technician.

All other On LED sequences that shut down or mute the D-POWER 7 indicate a serious internal fault. At this point, turn the D-POWER 7 off, remove AC power and have the amplifier serviced by a qualified technician.

5.4 Problem: No Channel Separation

• Check the mode indicators on the front panel and make sure the mode

selector on the rear panel is in the Stereo-position.

• Make sure other equipment in the signal path such as mixers and

preamps are set for stereo, not mono.

P.23

5.3 Problem: No Sound or Sound Is Too Low

Indication: On LED not or sporadically lit Signal LED not lit Clip LED lit

Under Impedance Limiter is active. The load impedance is abnormally low or shorted.

• Unplug each speaker one-by-one. If the On LED indicates normally when

you disconnect a cable, that cable or speaker is shorted.

• Take care not to use too many speakers in parallel, which would result in

an impedance that is too low for normal operation!

USER MANUAL

D-POWER 7

5.5 Problem: Distorted Sound

Indication: On LED lit Signal LED responding to signal level Clip LED lit only green

• A faulty speaker or a loose connection could cause this. Check the wir-

ing and the speakers systematically (i.e. step by step) and replace them if nec essary.

• The signal source might be clipping. Keep the D-POWER 7 volume pots

at least halfway up so that the source does not have to be overdriven.

• Keep the D-POWER 7 Volume Pots at least halfway up and try changing

input sensitivity from 1,4 V to 32 dB or 26 dB with the Gain Selector on the rear.

5.6 Problem: Hiss

• Unplug the amplifier input to check that the hiss is coming from the

source or from a device upstream. Erratic or popping noises indicate an electronic fault in the offending unit.

• To keep the noise floor low, operate the primary signal source at full level,

without clipping.

•Avoid boosting the signal further between the source and the amplifier.

5.7 Problem: Squeals and Feedback

• Microphone feedback must be eliminated by the mixer controls. If noise

continues to build up with no microphone gain, there is a serious fault in the signal processors or cables. Working in stages from the signal source towards the amplifier and check each device in the signal path by reducing its gain or by unplugging it
