Product information SRM-700S electrostatic headphone driver
Productnumber

212682

The SRM-700S is an electrostatic headphone driver utilizing a fully discrete dual FET. The output of the J-FET and the large current emitter follower circuit are low noise. Accurate music reproduction is realized without missing any fine details.
New semiconductor driver with J-FET in the amplification stage. The custom-made, low-noise dual FET is low-noise.

Type: All-stage FET configuration DC amplification driver unit

Frequency response: DC – 100kHz (with one SR-009S)

Gain: 60dB

Harmonic distortion: 0.01% or less (1kHz/100Vrms output)

Input impedance: 50kO (RCA), 50kOx 2 (XLR)

Maximum output voltage: 450Vrms (1kHz)

Bias voltage: PRO 580V

Operating temperature / humidity: 0 to 35 degrees C / less than 90% (non condensing)

Input terminal: RCA x 1, XLR x 1

Output: RCA parallel output terminal

Power consumption: 46W

Dimension: 240W x 103 H x 393 D mm (maximum protruding portion included)

Weight: 6.3kg
