SylphAudio [Stereo Preamp Buffer Module ] OPA1612 Single Supply Input

Ultra low distortion and ultra low noise buffer or preamp. Can be used as a buffer for instrumentation ADC. The best preamp partner for FB100 or FB360.

20Hz-20kHz Flat Frequency Response across different gain settings.

SE / BAL input switch by relays, no complicated wirings / jumpers.

Only requires 26V to 75V single supply, no complicated power supply requirement.

No capacitors in the signal path! Carefully selected power supply configuration to ensure natural, dynamic, and smooth sounding audio.

All OPA1612 opamps. +/- 17.4V DC rails generated onboard. Panasonic FC and Elna Silmic II capacitors for opamp rails.

Up to 21Vrms balanced output. (28.66 dBu max level)

Low profile and space saving vertical chassis mounting.

Modes:

SE INPUT or BAL INPUT = Simultaneous SE and BAL OUTPUT

SE output is always -6dB lower than BAL output, both are working simultaneously.

BAL/SE header: open = BAL input, short = SE input

****
Terminals / Connections
SE I/O = (GND)(IN+) and (GND)(OUT+)
BAL I/O = (GND)(IN+)(IN-) and (GND)(OUT+)(OUT-)

****
Default Gain is 6dB.

Gain can be adjusted by changing resistors on the back PCB or by specifying in your order.

Gain | RU | RG
0dB | 51Ω | Open
6dB | Open |Open
10dB | Open | 820Ω
14dB | Open | 316Ω
16dB | Open | 220Ω
20dB | Open | 120Ω
