Small, But Packs Massive Punch

BOSC uses the latest in Gallium Nitride (GaN) technology to achieve high performance in a small package.

The low on resistance and low capacitance of the GaN FET enables high efficiency and lowers loop impedance for low Transient Intermodulation Distortion (T-IMD). The fast switching capability and zero reverse recovery charge enable higher output linearity and low cross over distortion for lower Total Harmonic Distortion (THD). 

Preliminary Specifications:

  • Gain: 16.8dB or 6.92 (For 8 and 6Ω speakers)
  • Gain: 13.8dB or 4.89 (For 4 and 3Ω speakers)
  • Signal to Noise Ratio (SNR): 121dB (A-weighted)
  • Total Harmonic Distortion (THD): <0.0003% (-110dB) @ 9W
  • Frequency Response: DC - 40kHz
  • Sensitivity: 2.5Vin for 37.5W
  • Input Impedance: 5kΩ fully balanced for 8Ω amp
  • Input Impedance: 7.1kΩ fully balanced for 4Ω amp
  • Output Power: 150W
  • Damping Factor: >400 @ 1kHz
  • Size:  5.5" (14cm) x 4.8" (12.2cm) x 1.9" (4.8cm)
