The Story

Balanced audiophile phono stage

  • 5-pin mini XLR balanced input
  • balanced XLR outputs
  • symmetrical & discrete gain stage
  • easy settings adjustment
  • MM & MC capable
  • Dual mono design
  • Aluminium casing
  • Made in Europe

The new S3 phono stage.

The symmetrical design is the real standout feature! Connect your turntable with the 5-pin mini XLR cable & profit of the balanced signal path. The gain stage of the new Phono Box S3 B uses a fully discrete layout. A discrete circuit is composed of electronic components which are disparate, individual devices.

Semi-passive EQ

After treating the balanced +/- signals independently they are added back together and are processed by the
semi-passive RIAA equalization stage. By keeping the gain stage fully symmetrical, we can optimize the signal-to-noise ratios and keep interference to a minimum, giving the EQ section the best source to work its magic on.

Input impedance 10, 50, 100, 1k, 47k ohms
Input capacitance 50, 150, 300, 400 pF
Gain (+ 6dB using XLR Out) 40, 45, 60, 65 dB
SNR MM (40dB) 103dBV, 110dBV – ‚A‘ weighted
SNR MC (60dB) 85dBV, 90dBV – ‚A‘ weighted
THD at 1 kHz <0,001% MM, < 0,005% MC
THD (20Hz-20kHz) <0,008% MM, < 0,01% MC
RIAA-equalization curve accuracy <0,3dB / 20Hz – 20kHz
Subsonic filter at 20Hz with 18dB/octave
Input 1x 5-pin mini XLR / 1x pair RCA phono sockets
Line-level output 1x pair RCA, 1x pair XLR
Power supply DC 18V/500mA
Power consumption 18V/170mA DC, <0.5 W in standby
Dimensions 206 x 55 x 153 (164 with sockets) mm
Weight 930g without power supply
