1.3 The Amplifier
The D-POWER is a Class-H power amplifier with a power output of:
D-POWER 2 1200 W per channel @ 4 Ω
2400 W in Mono-Bridge @ 8 Ω
2400 W in Parallel-Mono @ 2 Ω
D-POWER 3 1600 W per channel @ 4 Ω
3200 W in Mono-Bridge @ 8 Ω
3200 W in Parallel-Mono @ 2 Ω
D-POWER 4 1900 W per channel @ 4 Ω
3800 W in Mono-Bridge @ 8 Ω
3800 W in Parallel-Mono @ 2 Ω
D-POWER amplifiers are fitted with Switched Mode Power Supplies (SMPS),
which significantly reduces the weight and size (only 2U) of the amplifier. Using
SMPS, the 2 symmetrical supply voltages of the power amplifier are more stable
than the power supplies used in conventional amplifiers.
The D-POWER has been designed as an intelligent and powerful product 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 allow access to the
functionality.
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.
