Description

The Objective2 Headphone Amplifier is the first design of the US blogger and electrical engineer NwAvGuy which is produced under the Common Creative License  Creative Commons License 

This outstanding performance has now been paired with the ObjectiveDAC (ODAC revB), a truly transparent 24bit DAC produced by Yoyodyne Consulting

Technical Specifications:

  • 3.5mm Input and 6.3mm Output Connector
  • RCA output on backside
  • build in ODAC with mini USB connector
  • ALPS Stereo Potentiometer
  • 230V~ 15 VAC 500mA Power supply (EU, UK, AU and US supplies available)
  • back power inlet to avoid cable clutter
  • Gain switch (2.5x and 6.5x gain as standard)
  • Size 108.5 x 84 x 30 mm (without Knobs and screws)

Thanks to the RCA output (muted when headphones are plugged in) you can use it as well to drive some monitor speakers or power amplifier. Even so it is not its original intend, it works very well.

An USB cable (90cm/3ft) with ferrite bead and gold plated contacts is included for free, longer cables are available separately.
