Note:
Please install the sound card driver before use.

Features:
Support AES/EBU, IEC60958, S/PDIF
Really supports 5.1 channel and 7.1 channel. Can be connected to 5.1 speakers
Sampling rate up to 48KHz, supports 32KHz/44KHz/48KHz digital recording function
The optical fiber output of the sound card only supports the sampling rate of 48KHz, so DTS-CD is 44KH and needs to be converted before listening.
Support Win98/ME/2000/XP/VISTA/WIN7/WIN8/MAC OS9.1 (only 2 channels can be used in MAC)
Playback and recording of full-duplex audio streams without the need for a PC built-in sound card
USB2.0 is backward compatible with USB 1.1;
Compatible with audio device specification V1.0;
Supports USB full-speed transmission specification up to 12Mbps;
3 input terminals (one of which is optical input)
3 output terminals and 1 optical fiber output terminal;
Special note: The mixing and reverb functions of the sound card cannot be used at the same time.

If you want the optical output to support 5.1 channel output, the following conditions must be met:
1. The audio source must be DTS5.1 channel, such as 3D games, high-definition videos. If it is a general MP3 or a general 2-channel video, it can only have 2-channel effects.
2. The setting of the player is very important: if you use the PowerDVD software, set the "Passthrough" output from the optical fiber. This means that the sound card is only responsible for outputting the optical fiber signal without decoding. It is recommended to use the KMP player, which is very powerful. .
3. The optical fiber output must be connected to an AC3/DTS decoder or a power amplifier with a built-in AC3/DTS decoder.

Purpose 1: Connect the computer to 5.1-channel speakers. If the speaker audio input is a 3.5mm stereo interface, you need three 3.5mm stereo audio cables to connect; if the audio audio input is an RCA lotus connector, you need three 3.5mm to lotus connector cables. After connecting the sound card to the computer and installing the driver, connect the audio cable. In terms of software, it is recommended to use decoding or perfect decoding, as well as KMP and so on.
Purpose 2: Set the decoding to S/PDIF output, set the sound card to turn on S/PDIF output, and then play; (Only use the normal settings for the decoding settings here. You can also choose other options such as re-encoding DD5.1 output according to different situations. ), and here is a special reminder: the optical fiber output is the source code directly output to an external decoder such as a power amplifier for decoding, regardless of the channel output.
Purpose 3: The above are the settings for watching movies. When you use it for karaoke, you only need to check the input "Stereo Mix" option in the mixer tab; you can also select it in the corresponding software. (Note that when using Stereo Mix, the microphone reverb function cannot be used)

Specifications:
Product name: USB external multi-function sound card
Color: Gray/Silver

Input and output interface:
mic in= microphone input: plug in the microphone
line in= Line input: Input audio such as MP3 to the sound card for synthesis and editing on the computer
front out= Front output: Plug headphones or speakers into the 2-channel channel/Plug in the front speakers in the 4-channel channel
rear out= rear output: turn on more than 4 channels to produce sound/plug in rear speakers
