Working Principle

LFP1100-A4NMB is a differential amplifier consisting of an input stage at the input end and an output stage at the output end to provide the gain. It uses a type of semiconductor called extrinsic silicon (NMB) to resist any kind of interference, such as muscle tension or noise. This feature ensures a distortion-free and clear signal.

The input stage is composed of a differential voltage amplifier, which accepts two audio signal inputs consisting of high frequency switches. The input is processed and amplified by the main amplifier, which produces an amplified signal with high precision and low distortion. Then, the output is regulated by the low distortion output stage that also provides extra power control.

The combination of the two stages increases output power and maximizes power efficiency by producing low heat dissipation. Additionally, LFP1100-A4NMB is equipped with an adjustable voltage regulator to ensure consistently low distortion even when the power and load conditions vary.
