BOSC - HiFi Monoblock Class-D Amp

Small, But Packs Massive Punch

Currently under development.


BOSC uses the latest in Gallium Nitride technology to achieve high performance in a small form factor.


The low on resistance and low capacitance of the Gallium Nitride (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
  • Signal to Noise Ratio (SNR): ~120dB
  • Total Harmonic Distortion (THD): <0.0006% (-105dB) @ 5W
  • Frequency Response: DC - 40kHz
  • Sensitivity: 2.5Vin for 37.5W into 8Ω 
  • Input Impedance: 5kΩ fully balanced
  • Output Power: 100W into 8Ω w/ 48V Power Supply
  • Output Power: 150W into 8Ω w/ 56V Power Supply
  • Size:  5.5" (14cm) x 4.8" (12.2cm) x 1.9" (4.8cm)
