ADA-25 USB - HQ MID audio

The compact AXAGON ADA-25 USB HQ audio adapter adds an advanced external USB sound card with analog and digital output to your computer.

A high-quality 24-bit sound with up to 96 kHz sampling, both in playback and stereo recording e.g. from a mobile phone, MP3 player or when digitizing recordings from the old magnetic tapes.

Comfortable button control for direct volume control and microphone or headphone muting.

The above standard equipment in the form of an optical digital S/PDIF output will be appreciated by fans of high-quality listening to music as well as players and movie viewers after extension by a multi-channel audio support for Windows.

Easy use thanks to an automatic installation, which can be handled even by a layman.

A compact and lightweight design of the USB DAC converter is suitable for both desktops and laptops and allows connection of not only stereo headphones and a stereo microphone or headset, for example for the Skype service, but due to the optical output also of high-quality stereo equipment or home cinema. In the case of need, it also serves well as a replacement for the broken original sound card in your laptop.
