Where to buy
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.

FAQ
A): The basic drivers are already part of the operating system.
B): When you connect the USB sound card to your computer, the necessary drivers are automatically detected and installed.
A): If the USB sound card is not displayed in "Device Manager", there may be a USB port malfunction.
B): Try plugging the sound card into another USB port. The sound card should be detected and the drivers loaded automatically. If the problem persists, plug the sound card into the USB port of another computer to verify its functionality.
A): You probably have enabled the “Listen to this device" option in the sound properties of the microphone.
B): To disable this option, go to http://www.axagon.eu/en/novinky/novinky/easy-help-with-fixing-a-microphone-echo.
A): The USB sound card cannot be used without a computer, e.g. by plugging into a TV.
B): The USB sound card uses the computer, its operating system and drivers for its operation. So it cannot operate without a PC.
A): The sound interference is probably caused by a wireless mouse transmitter.
B): We recommend that you place the mouse transmitter as far as possible from the sound card (preferably on the opposite side of the computer - the transmitter to the USB on the front PC panel and the sound card to the USB on the back of the PC - use a USB extension cable if necessary). If it is a laptop, then one device on each side.
A): The problem could be a lack of resources, check (when a problem occurs) the processor load and operating memory filling in "Task Manager".
B): If the CPU usage is 100% or memory is full, you need to find out what causes this situation. Another option is to connect a sound card to another computer to verify that the sound card is not damaged.
A): On most Axagon USB sound cards, the line input is merged into the microphone input.
B): The sound card has the ability to recognize whether a microphone or stronger "link" signal is connected. So, for example, when recording from the headphones output of a mobile phone, you need to reduce the volume on the phone to 80-90 % or reduce the signal intensity in the recording software so that the signal is not overexcited. In the recording software (such as Audacity), you need to set up the Microphone-USB as the signal source.
A): The USB sound cards generally have a higher latency (delay).
B): The solution is to use the ASIO4ALL drivers (http://www.asio4all.com/). ASIO are special sound drivers designed to achieve the smallest latency.
A): Yes, for example, the ADA-17 sound card can be used for Raspberry Pi.
B): The installation can be handled even by a layman, only plug the sound card into the USB port of the computer and the rest is done automatically.
A): You probably have allowed to listen to the microphone in Microphone Properties.
B): To disable this feature, follow these steps: Start -> Control Panels -> Hardware and Sound -> Sound -> Recording -> Microphone (USB Sound Device) -> Properties -> Listen -> Listen to this device - uncheck this box and confirm with "Apply".
A): Yes, you can set up two different tracks playing back simultaneously on one computer.
B): This is primarily a software issue requiring a player that supports sound redirection to a different sound card output than is set as "default" in the OS. Such functionality is supported, for example, by the VLC media player.
