Signature System SR-407 earspeaker with SRM-006tS driver

The SRS-4170 is a high-quality combination system of the earspeaker SR-407 (Signature) employing the same sound element as the new Λ series SR-507 and the SRM-006tS driver unit with the vacuum tube output stage.

The SRM-006tS is equipped with two RCA and one XLR input terminals and the double-axis 4-gang volume controller can accept fully balanced source signals. Moreover, in order to make the most of full balance circuit, each low-noise FET was carefully measured and thermally combined each other. This resulted in the stable operation of the completely direct-coupled DC circuit with no coupling capacitor and brings out the maximum performance of the SR-407 full-balance sound element. The comfortable string and rich low- and mid-range sound of the SRS-4170 system covers all genres from vocal to orchestra and enables you to enjoy music over a long period of time.

The PC-OCC special-made wide low-capacity parallel cable employed for the SR-407 can send signals from the driver unit to the sound element with little loss, realizing clear and distortion-free music reproduction.
