Specification

The SRS-3170 is a standard combination system of the SR-307 with the sound element featuring the same new material "super engineering plastics" diaphragm as upper models and the SRM-323S solid-state DC amplifier with all-stage direct-coupled balance output circuit configuration.

The SR-307 adopted the PC-OCC low-capacity parallel cable with the gold-plated plug, securing the reliability over a long period of time. The SR-307 can offer more natural sound stage of the electrostatic type earspeakers in combination with the SRM-323S.

The emitter follower output stage of the SRM-323S using high-voltage bipolar transistors lowered the output impedance to improve the drive capability, and also expanded the dynamic range of a high-frequency range. Moreover, the power transformer equal to that of the SRM-006tS has been adopted to achieve powerful derivability not only for musical reproduction but also for monitoring purpose of professional use.
