SRM-313
DRIVER UNIT FOR STAX EARSPEAKER
Low Impedance Output Stage
The SRM-313 Driver Unit features a completely redesigned output stage that utilizes an up-to-the-minute emitter follower in the output circuitry. This along with a further improvement in the power supply circuitry results in life like sound rich in scale and dy­namics.
FEATURES
The SRM-313 drives STAX electrostatic earspeakers without deterio­ration in tone quality since there is no transformer used between the amplifier and the Earspeaker.
The simplified two-stage amplifier having a low-noise dual FET in the first stage and a high dielectric strength transistor in the second stage realizes natural tone quality with a great deal of sound infor­mation.
All the circuitry from the input to the output is DC circuitry without use of coupling capacitors.
According to STAX's design concept, non-magnetic parts are used as much as possible together with the non-magnetic chassis.
Long life electronic parts are selected to ensure tone quality.
The SRM-313 is capable of driving all STAX earspeakers of Pro
bias, Normal and the electret types.
For convenience of connection with other appliances, the SRM-313 is equipped with lNPUT and OUTPUT terminals that are connected in parallel for the right and left channels respectively.
