This earspeaker and driver unit will allow any high-level audiophile to enjoy a wide variety of combinations. An intelligent set model that can be placed by the bedside or in any private space. The system is supplied as a set consisting of the exclusive system model SR-202 Basic and the driver unit SRM-300. A push-pull signal is obtained by low-noise FET input OP Amp, for ICL input. The output stage consists of a simple inverting amplifier based on low-noise FETs and high voltage transistors. The SRM-300 regulates power for clear sound in bias voltage in power supply. Parallel input and output terminals connects to an amplifier for loudspeaker and earspeakers.
