Where to buy

The AXAGON ADA-15 USB HQ audio MINI adapter easily and quickly adds an external USB sound card to your computer.

The installation can be handled even by a layman - only plug the adapter into the USB port of the computer and the rest is done automatically.

The miniature sound card is suitable for both desktop and laptop computers and allows stereo headphones, microphones or headsets to be connected for Skype service, for example. It also serves well as a replacement for the broken original sound card in your laptop.

The advantage of the ADA-15 USB DAC converter is, however, the high-quality 24-bit audio 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.

2-channel analog 16/24-bit output (3.5 mm stereo jack):
stereo output for headphones or active speakers.

2-channel analog 16/24-bit input (3.5 mm stereo jack):
stereo microphone input and input for recording analog signal.

Sampling rate, resolution and output converter (DAC) noise:
• analog - 44.1 / 48 / 96 kHz @ 16 / 24 bit for playback,
• Signal-to-Noise ratio (Output SNR) ≥ 95 dB,
• harmonic distortion (Output THD + N) ≤ -85dB.

Sampling rate, resolution and input converter (ADC) noise:
• analog - 44.1 / 48 / 96 kHz @ 16 / 24 bit for recording,
• Signal-to-Noise ratio (input SNR) ≥ 90 dB,
• harmonic distortion (input THD + N) ≤ -80dB.

Green LED indicating data transmission (blinking).

Other features:
• USB 2.0 full speed 12 Mbit/s and USB 1.1 compatible interface.
• Built-in direct USB Type A male connector.
• Easy to install thanks to full Plug and Play support.
• Possibility to connect your device while running thanks to the Hot Plug support.
• Compliant with the USB Audio Device Class specification v1.0.
• Compliant with the USB HID Class specification v1.1.
• Adapter power supply via USB (bus power) - no auxiliary power supply required.
• Miniature dimensions of 39 x 24 x 12 mm, when inserted into the USB port, the adapter protrudes only 27 mm.
• Weight only 8 g.
• VIA VT1630A chipset is used.

Setting up a sound card in Windows allows:
• adjusting volume and balance of speakers,
• setting for microphone in-ear monitoring,
• enhanced speaker features: Bass Boost, Virtual Surround Sound, Room Correction, Loudness Equalization,
• setting the sampling rate and bit depth for both reproduction and recording,
• setting the automatic level of gain for the microphone (Automatic Gain Control),
• setting the manual level of gain for the microphone.

Supported OSs: MS Windows XP / Vista / 7 / 8 / 8.1 / 10 and later, Windows Server 2003 / 2008 / 2012 / 2016 and later (supported are all 32- and 64-bit Windows OS versions), Mac OS X 10.4.x and higher, Linux with kernel 2.6.x and above.
Note: Drivers are included with supported operating systems and are installed completely automatically. No other drivers need to be installed and are not even available.  
Compatible with all Internet telephony programs using the sound card.

Package contains:  
• audio adapter,
• packed in a blister with a sealed-on back card with the installation procedure.

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

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 ( 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.
