Axagon ADA-HP

HQ USB external sound card Axagon ADA-HP is an extremely compact and yet an extraordinary combination of functions as an optical digital output, headphone amplifier or hardware equalizer. In addition, it is equipped with a LED, a connection to USB and three LEDs indicate the sampling frequency played or recorded sound. Another advantage is the possibility to use 4pin headset on one cable.

The advantage of USB DAC ADA-HP is a high-quality 24-bit audio with up to 96 kHz sampling during playback and recording with stereo eg. from a mobile phone, MP3 player, or when digitizing recordings from old cassette tapes. Upgraded equipment in the form of digital optical S/PDIF output is well appreciated by lovers of quality music and on the other side, it also can provide support to multi-channel audio in Windows and players and film viewers. Headphone amplifier with accurate and convenient volume control knob allows you to connect high-quality headphones with higher impedance and thus control their volume independently from the computer. The hardware equalizer, in turn, will help enhance the bass or treble track.

Compact and lightweight USB sound card with a USB cable-fixed is particularly suitable for notebooks and allows connection of stereo headphones not only a stereo microphone or headset eg. For Skype, but it can also be used as an optical output stereo system or home theatre. In an emergency, it can also serve as a substitute to a faulty original soundcard.
