Established in 1983, CAMCO has gained worldwide experience with
professional sound reinforcement technology. Within the audio market,
CAMCO specialises in the production and marketing of high quality power
amplifiers and sound systems for use both on tour and in static installations.
The success of the TECTON and VORTEX series power amps has made the
CAMCO name synonymous with professional quality, high performance
and utterly reliable power amps.
CAMCO’s commitment to research and development, seen not just in the
area of materials and technology but also most importantly in its highly
skilled and motivated workforce, is one of the keys to its ongoing success.
With its all-new D-POWER 7 power amp, CAMCO is pioneering a new dimension in professional power amp construction. The seamless combination of ground-breaking technology with proven safety elements is the
hallmark of the new amplifier.
Welcome to the new world of professional power amplifiers –
1 WELCOME / 2 THE AMPLIFIER
WELCOME TO CAMCO!

D-POWER 7
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.

3.1 Mains supply
When mounting or connecting the amp always disconnect it from
mains. Only connect the D-POWER 7 amplifier to an appropriate AC circuit and outlet, according to the requirements indicated in the second
line on the rating plate.
D-POWER 7
230 V ~ 50/60 Hz 12 A 1800 W
xxxxxxx
3000 W / 2 Ohm
Exemplary rating plate for a mains supply of 230 V AC 50/60 Hz.
Power Supply Data:
Voltage Mains Frequency Current Power Consumption
100 V 50/60 Hz 28 A 1800 W
120 V 50/60 Hz 24 A 1800 W
220 V 60 Hz 12 A 1800 W
230 V 50/60 Hz 12 A 1800 W
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
≤ 75 A and subject to conditional connection”.
If in any doubt, consult your local power provider. Never attempt to
measure this impedance level with your ohmmeter. This may damage
your meter and expose you to the risk of electric shock!
