Features:

Support AES/EBU, IEC60958, S/PDIF.

Really support 5.1 channel, 7.1 channel. Can be connected to 5.1 speakers

Up to 48KHz sampling rate, support 32KHz/44KHz/48KHz digital recording function.

Sound card optical output only supports 48KHz sample rate, so DTS-CD is 44KH need to be converted to listen to

Support Win98/ME/2000/XP/VISTA/WIN7/WIN8/MAC OS9.1 (MAC can only use 2-channel)

Full-duplex audio stream playback and recording without PC built-in sound card

USB 2.0 is backward compatible with USB 1.1;

Compatible with Audio Device Specification V1.0;

Supports up to 12Mbps USB full-speed transfer specification;

3 input terminals (one of which is an optical input)

3 output terminals and 1 optical output terminal;

Special note: the sound card's mix and reverb functions cannot be used at the same time

If you want the optical output to support the effect of 5.1 channel output, you must have the following conditions:

1. The audio source must be DTS 5.1 channel, such as 3D games, HD movies. If it is a normal MP3 or 2-channel film, it can only have 2-channel effect. 2.

2. Player settings are very important: If you are using PowerDVD software, set the output from optical "Passthrough". This means that the sound card is only responsible for outputting the optical signal, not decoding it. 

    We recommend using the KMP player, which is very powerful. 

3. The optical output must be connected to an AC3/DTS decoder, or an amplifier with a built-in AC3/DTS decoder.

Specification:

Product name: USB external multi-function sound card

Colour: grey, silver (optional)

Material: aluminium alloy

Cable length: 11cm

Input and output interfaces:

mic in= microphone input: plug the microphone of the

line in= line in: MP3 and other audio input to the sound card, in the computer synthesis editing use

front out= front out: 2-channel headphones or speakers / 4-channel front speakers

rear out= Rear out: 4 or more channels of sound/plug in the rear speakers.

cen/bass out= centre/bass out: 5.1 speaker dedicated connector, (Note: centre and bass are the same 3.5 connector, you can set the priority order of centre or bass in the main setup interface. The default output of this hole is the centre output, bass will only appear in the film there is a fire scene, it is not the sound card does not have bass output)

SPDIF IN= Optical Fibre Input: Optical Fibre Audio Input to the sound card for compositing and editing in the computer.

SPDIF OUT= Optical Output: Generally output to optical amplifier or decoder (digital signal).

Use:

1. Computer connected to 5.1 channel speakers. If the audio input of the speakers is 3.5mm stereo interface, you need three 3.5mm stereo audio cables to connect; 

    if the audio input is RCA lotus head, you need three 3.5mm to lotus head cables. Just plug the sound card into your computer and install the driver, then connect the audio cable. 

    In terms of software, it is recommended to use decoding or perfect decoding, as well as KMP and so on.

2. In the decoding settings for the S/PDIF output, sound card settings to open the S/PDIF output, playback can be; (here decoding settings only use the ordinary settings, 

    you can also choose to re-encode the DD5.1 output according to the different circumstances, and other options.) 

    In addition, here is a special reminder: optical output for the source code directly to the external decoder such as amplifiers and other decoding, not divided into channels output.

3. The above settings are for watching films. When you use it for Karaoke, you only need to tick the input "Stereo Mix" option in the Mixer tab; you can also select it in the corresponding software. 

   (Note that the microphone reverb function is not available when using Stereo Mix).
