Alpha Design Labs 24bit/192KHz GT40α USB DAC with MM/MC Phono Stage and variable pre out

  • High performance 24bits/192kHz “VIA VT1736 “USB chip and 24bits/192kHz “Cirrus Logic CS4270” DAC /ADC chip
  • USB Recording Resolution: 24bits/192kHz (Max) supports 44.1 /48 /88.2 /96 /176.4 /192 (kHz)
  • Frequency response: 20Hz ~ 20kHz (+/-0.5 dB) 
  • Enjoy audio in high resolution at 24bits/192kHz surpassing conventional 16bit/44.1KHz standards
  • Incorporates the most trusted driver in professional audio for 24bits/192kHz recording and playback
  • External power supply: while a USB-powered device might be convenient, it won’t develop the power required for high resolution playback, so we designed the GT40α with an external power supply to solve the problem.
  • Headphone Amplifier: It contains a high performance “Maxim MAX9722A” headphone amplifier with ample drive for good headphones
  • Analog-to-Digital Converter: The GT40α sports a high-performance ADC IC chip for high resolution recordings via analog inputs including phono, AM/FM radio, or other analog signals.
