The distortion in this type of amplifier is said to be minimum which results in better performance.

. Of the above said classes Class A has least distortion then Class AB and then Class B. Dual voltage and current feedback loop Proprietary design combines Class-D efficiency with a unique current and voltage feedback loop circuit that continuously monitors and controls both the current and voltage delivered to the loudspeaker load. Planet Audio BBD2500 Class D Car Amplifier 2500 Watts 1 Ohm Stable Digital Monoblock MOSFET Power Supply.

Darlington Class AB Amplifier. In numerous applications where the push-pull configuration has used the resistance of the load is less. Metal Oxide Semiconductor Field-Effect Transistors quickly switch from full to non-conduction for high efficiency output.

Class B has the highest efficiency 785 then Class B between 785 to 50 and then Class A 50. Any way Class AB configuration has reduced efficiency and wastes a reasonable amount of power during zero input condition. To overcome the drawback of the unnecessary heating of the device class B circuit of the power amplifier was designed.

The amplifier is not really recommended for in-ear monitors due to the overwhelming power outputs and high noise floor. Independent of power level and load impedance the amplifier consistently delivers the widest possible dynamic range frequency. The Ragnarok 2 amplifier like its predecessor has a very transparent rich and clear tonality.

The maximum efficiency for class B amplifier can be fined as. The overall current gain Beta β or hfe value of a Darlington device is the product of the two individual gains of the transistors multiplied together and very high β values along with high Collector currents are possible compared to a single transistor circuit. The angle of conduction for this class of amplifier is considered to be 360 degrees.

While efficiency for class A amplifer is 25 percent. In all gain settings the Ragnarok 2 demonstrates excellent ability in delineation with quick transients and separation. Ƞ max Pout PDC 025IcsatVCC IcsatVCCȠ 025π.
