SRM-323S Solid State Driver Unit

The emitter-follower circuit with high-voltage bipolar transistors adopted for the output stage of the SRM-323S enabled low output impedance resulting in increased drivability and wide high-frequency dynamic range. Moreover, the power transformer equal to that of the SRM-006tS has been adopted to achieve more powerful derivability. One simple RCA input is equipped with a parallel-out terminal directly providing the incoming signal. Two 5-pin output sockets are connectable to all pro-bias compatible earspeakers. The SRM-323S employs a double-axis volume controller to control left-and -right channel volume level independently without using a balance volume controller.
