Adjustable sound with 12AU7 tube and 3-band EQ: Precisely tailor treble, mid and bass to room and preference.
Diverse sources and low-loss digitization: USB, S/PDIF optical, RCA/phono, line-in and aux in; save analog signals on a PC or notebook as files.
Powerful headphone operation: Reliably drives 16-600 Ohm, with 3.5 mm and 6.3 mm outputs.
Stable, low-noise playback: Asynchronous USB mode, De-pop function and metal housing reduce background noise.
This USB DAC with integrated 12AU7 tube connects computers, players and headphones into a high-quality listening chain. The combination of high-resolution DAC and analog 3-band tone control enables fine adjustment to the recording, speakers or headphones. Use the Input Select button to switch comfortably between the inputs; in parallel, headphone outputs in 3.5 mm and 6.3 mm as well as line, S/PDIF/pre and bass outputs are available.
In professional IT environments, in on-site installations, in service deployments or in existing infrastructures of companies and public institutions, the device supports both precise monitoring at the desk and the archiving of analog collections. The reliable A/D recording function helps to digitize records and cassettes cleanly and make them media-neutral.
