All My media comes out of my Mac (DVD, CD, MP3, audio/video from the web and computer software, etc.) and I have self powered speakers, so I don't need the expense or large footprint of a receiver. This USB SoundBox 7.1 is just what I was looking for, and works great on my MacMini desktop computer and MacBook laptop with OSX 10.6 Full multi channel output capability and excellent sound quality. Plug and Play operation + Apple operating system, makes it to set up for 2, 4, 6, or 8 channel operation. The supplied software is for PCs only, I don't need it to run it on my Mac. It has a blindingly bright flashing blue power Led, on top, that I covered with black electricians tape, as it was a bit distrating. Comes with a nice long USB cord with full size conectors, and it gets its power through the USB cord. No wall wort, Yay! All inputs and outputs are clearly marked in English. Lightweight and compact (not much bigger than a deck of cards), it will easily fit in a laptop case. I highly recommend this to anyone who has a Apple Mac computer. I think the sound quality is better than the Macs built in audio ports. It looks to be the same as the Vantec USB External 7.1 Channel Audio Adapter: Vantec USB External 7.1 Channel Audio Adapter (Black) Enjoy! Review: Killed my sound system - I bought this in anticipation of the new laptop I was getting. I wanted to be able to use the 5.1 sound system that I had used on my old desktop with the new laptop. I was able to install the drivers and hook everything up easily. When I turned it on it seemed to be working fine. So I switched the sound system from normal mode to music mode. A few seconds later one of my rear speakers started making a loud popping sound, and the front speakers started making a crackling sound. I immediately unhooked the sound system and hooked it back up to my old desktop, and the popping and crackling were still there. I don't know what happened, but this killed my sound system. ## Features - Does not support full surround for windows 10. Product will be updated soon to support this. - Full analog 7.1 audio through 3.5mm jacks - Digital 7.1 audio supported through Fiber Optic S/PDIF input and output (2.1 audio if used with Mac OS) - Record in Stereo through 2 Microphone inputs - Small and compact for portability; about the size of a deck of cards, Easy-to-use volume control buttons - Analog supports 48/44.1 KHz sample rate for both recording and playback (S/PDIF in and out only support 48 KHz sample rate) - Full-duplex recording and playback - USB 2.0 compliant ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B004Y0ERRO | | Audio Output Mode | Stereo, Surround Sound | | Best Sellers Rank | #870 in External Sound Cards | | Brand | Sewell | | Customer Reviews | 3.9 out of 5 stars 379 Reviews | | Global Trade Identification Number | 00685289295455 | | Hardware Connectivity | USB 2.0 | | Hardware Interface | USB 2.0 | | Hardware Platform | Laptops, PC | | Item Weight | 7.2 ounces | | Manufacturer | Sewell Direct | | Maximum Sample Rate | 48 KHz | | Mfr Part Number | SW-29545 | | Model Number | SW-29545 | | Platform | Mac, Windows 8 | | Surround Sound Channel Configuration | 0.0, 7.1 | | UPC | 639767408653 685289295455 | ## Product Details - **Brand:** Sewell - **Hardware Interface:** USB 2.0 - **Audio Output Mode:** Stereo, Surround Sound - **Platform:** Mac, Windows 8 - **Hardware Platform:** Laptops, PC ## Images ![Sewell Direct Sound Box External USB Sound Card 7.1 and 5.1 Channel Audio (SW-29545) - Image 1](https://m.media-amazon.com/images/I/51Gk7zbNsGL.jpg) ## Questions & Answers **Q: I want to use this device to convert my Amazon Fire TV's optical output to a 6 channel, 5.1 digital output. Can I do this w/o a computer?** A: You cannot, they answer this question on their website:https://sewelldirect.com/usb-soundbox-71-and-51-sound-cardQuestion:Could this product be the link between my blu-ray player and my Logitech z506 surround speakers? My blu-ray player has an optical output and my speakers have 3x3.5mm inputs for the 5.1 surround sound.Answer:Unfortunately no, it wouldn't work that way. This converts USB sound from a computer to analog output, it can't convert a toslink to analog output. **Q: Is the microphone input stereo or mono?** A: Mine shows 2 inputs: left and right. I don't use mine for that purpose. I am assuming if you want stereo, you'll need 2 microphones. **Q: can you update for it to work with windows 10 ?** A: Hi there. This works out of the box with Windows 10 (I'm running it on Windows 10 now). **Q: Is this CPU friendly or distorts easily?** A: Seems to work just fine for me. No distortion and no apparent impact to CPU overhead. Works on Windows 8.1 just fine. Basic functionality works even without the driver. The driver adds the extras like the 7.1 surround. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works great on my Mac Mini with OS 10.6 *by D***E on December 15, 2011* I wanted something that would allow me to get multi channel analog audio, out of my Mac computers, without having to use a surround sound receiver.

I wanted to be able to use the 5.1 sound system that I had used on my old desktop with the new laptop. I was able to install the drivers and hook everything up easily. When I turned it on it seemed to be working fine. So I switched the sound system from normal mode to music mode. A few seconds later one of my rear speakers started making a loud popping sound, and the front speakers started making a crackling sound. I immediately unhooked the sound system and hooked it back up to my old desktop, and the popping and crackling were still there. I don't know what happened, but this killed my sound system. ### ⭐⭐⭐⭐⭐ Easy to use and good sound quality *by D***S on October 22, 2012* I needed this basically for an additional set of audio in and out ports. My PC's built in ports are being used for my headset, I needed to get a line in and line out for a second device, and this allows me to do that with a single USB line. I plugged it in and it was immediately detected and worked fine, but a few of the ports didn't show up until I installed the included driver. The only complaint is that the blue light on top (which blinks if you don't have the driver installed or stays on steady if the driver is installed) is really bright, to the extent that if I shut off the lights and my monitor, it's the brightest thing in the room, which was a minor annoyance when trying to sleep. I had to cover it with tape. As for some more specialized advice, the second device I'm using this for is an amateur radio. I have this connected to my TS-820S for use with soundcard modes, and it has a good 2dB improvement in signal reception signal-to-noise over the on-motherboard ports, and I get signal reports back that are slightly better, but it's very variable. You can buy better sound cards for this purpose, but let's be honest - this probably isn't going to be the weakest part in your system. Definitely the best value for your money for any purpose. By the way, this product is exactly the same as Vantec USB External 7.1 Channel Audio Adapter (Black) , Diamond External Xtreme Sound 7.1-Channel USB Audio Device , StarTech.com 7.1 USB Audio Adapter External Sound Card with SPDIF Digital Audio Sound Cards ICUSBAUDIO7D , and Sabrent USB-SND8 8-Channel 3D USB 2.0 External 7.1 Surround Sound Box with Digital Output .
