USB Sound Adaptor

I received the USB Dongle yesterday. ( http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=310401470794&ssPageName=ADME:L:OU:US:3160 ) First, it IS stereo in and stereo out. There is some confusing wording even on the packaging but it is indeed stereo all around. Someone suggested that the chip MAY not be as advertised. As this IS from China (with a Taiwanese chip) and having dealt with Asia for decades, I opened it (not recommended for the inexperienced, it is glued shut).
It is indeed the Via Vinyl Envy USB VT-1620A chip ( http://www.via.com.tw/en/products/audio/usb/vt1620a/index.jsp ). The Via driver from their web site loaded and recognized the chip so I am 100% sure it is genuine. It should be capable of:
a.. 2-channel ADC with 90dB SNR, 16/24-bit supporting 44.1/48/96/192kHz sample rates
a.. 2-channel DAC with 95dB SNR, 16/24-bit supporting 44.1/48/96/192kHz sample rates
I have some photos if anyone is interested. It is a nice little board and looks to be well made.
Both the input (Mic) and output (Headphones and SPDIF optical) are standard 1/8 stereo jacks with the output having the additional optical coupler mounted just past the electrical contacts.
It works great with HRD but I have no way of testing it for I/Q use as my KX3 is still a dream and my K3 is not equipped for I/Q out.
Maybe someone better equipped and more knowledgeable could put this little guy through some tests??? If so contact me. FYI my QTH is Watsonville.
BTW, I have no financial interest in this at all. This is all just FYI and me getting ready for my KX3 when the CFO gives me the go ahead.

Re: USB Sound Adaptor

I would be inclined to use whatever currently-existing on-board unit for the
maiden voyage.

Then, test that fancy usb unit out, and then tell us about the bandwidth.

Re: USB Sound Adaptor

In reply to this post by Clint-2

Don't you just hate when this happens after you (and I) have already bought
it. This site has them for $1.69

Has anyone verified if this will actually function in place of a USB
soundcard for pan-adapter use?

Re: USB Sound Adaptor

I purchased and tested one of these devices. It work poorly, with a
high noise floor and various spectral spikes. I tried it without an
isolator and it was even worse.

The Creative X-Fi SB1095 with the two capacitor mod mentioned elsewhere
in these discussions seems to work quite well, and certainly seems well
worth the $59 or so they usually cost, at least to me and my sample of
one device.

73,

Lyle KK7P

No financial interest in Creative Labs products, YMMV, this is my
personal experience and not an official Elecraft position or
endorsement, etc.

Re: USB Sound Adaptor

In reply to this post by Richard Fjeld

Richard,

WOW, how can anyone make money with a price like that?
It does not mention speed or bit depth or chip however, so I went to the mfg
web site, SYBA USA. This is not the same device. The one we bought is a
SD-AUD20101 (http://sybausa.com/productInfo.php?iid=1191&currentPage=0) so
don't feel bad about paying more!
I have been using it as a sound card and it is working well but I am not set
up for I/Q signals....
Just waiting for my KX3...

Clint

Re: USB Sound Adaptor

In reply to this post by Richard Fjeld

But be careful. There are several models that look alike externally. But only one has stereo microphone input. This is the one with stereo:
SYBA USB sound card
SYBA SD-AUD20101
VIA ENVY VT1620A
<http://www.amazon.com/Syba-Digital-Optical-Output-SD-AUD20101/dp/B006SF68P2/ref=sr_1_1?s=electronics&ie=UTF8&qid=1347141912&sr=1-1&keywords=syba+sd-aud20101>

It works. Haven't tested it for noise, etc., yet.

Re: USB Sound Adaptor

I purchased two of these devices from Amazon right before someone on this reflector posted that the one he bought got very hot to the touch and the seller took it back and refunded his money.

I now have two of these and neither has even gotten warm. Both seem to work fine. Can't believe no shipping charge as they arrived by USPS from China!
