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.
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
USER MANUAL
D-POWER 7
D - P O W E R
S E R I E S
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. Alternatively, contact your dealer or distributor.
