ADA-71 USB 7.1 SOUNDbox

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): Test the subwoofer with "Bass redirection" turned on. In the AC3 filter, it is also possible to set the limit frequency up to which the subwoofer will play the sounds. At a higher frequency, the sound from the subwoofer will be clearer.

B): Alternatively, try plugging in the "Center/BassOut" output on the audio adapter ordinary headphones that have a wide frequency range and subwoofer sounds should be heard in them. For testing, we recommend using the "Media Player Classic - Home Cinema" freeware in combination with the AC3 filter.

A): To start multi-channel sound in MAC OS, check your OS settings. http://www.dr-lex.be/software/surround_osx.html. Some versions of MAC OS had a bug, and the USB sound card must be connected only at the boot time.

B): Decoding surround sound is a matter of the software used by the player. The basis for 5.1 surround sound is the audio signal source, we recommend a movie DVD with 5.1 sound and a corresponding player that supports multi-channel sound. For testing, we recommend the VLC media player: http://www.videolan.org/vlc/download-macosx.html. It is also possible to try the C-Media CM6206 Enabler for Mac http://www.dr-lex.be/software/cm6206.html.

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.

A): In Windows, you probably do not have 5.1 sound configured. The problem might still be due to a poor system input setting. In Xear 3D on the first tab. The 6CH setting is for 5.1 sound source (such as DVD), so only two speakers play in case of a stereophonic input signal (e.g. mp3). To play mp3s on all speakers, you need to set 2CH input.

B): Open "Control Panels/Hardware and Sound /Manage Sound Devices" and under the “Playback” tab select "USB Sound Device"(should be a green mark near it), select "Configure"down on the left, and select the "5.1 Surround" speaker settings in the open setup wizard. In the next step, you can test individual speakers or make adjustments to them.

A): The "Speakers" option switches the sound card to audio outputs on the sound card (L + R, SW, Center, etc.) and disconnects the SPDIF. You cannot make a 5.1 digital from the stereo signal. The 5.1 Surround can be made from 2-channel audio only in an analogue way and use analog outputs on the sound card.

B): If you switch to SPDIF, a signal is directed to the digital output that is directly from the source recording. This means that if the recording is stereo, the SPDIF signal is in PCM format that is only two-channel. If you want 5 + 1, you need to use the 5 + 1 signal source (original DVD at best), then the signal is transmitted directly to the sound card in the so called "SPDIF AC3 Passthru" format and there is no change or degradation of the sound quality (of course, with the correct setting).
