What?

Usb Dual pro project series

Do you have the exact manufacturer and model number, or a link?

Does that thing have an instrument/guitar input? It might only have mic & line inputs…

If you have adapter cables, you can plug-in a CD player, or the audio from a DVD player, or an iPod, or the audio from your TV, etc.

Do you have a guitar amp to test the guitar and cable?

I plug in my semi acoustic into either of the two 1/4 available. guitar has new 9v to send signal to DigitalAudioDevice. I then have the device plugged into by usb a/b supplied cord. Guitar - DualPre - Laptop.

I selected codec usb and no signal…I switched to test record from internal mic and can get a recording into Audacity…

*** Windows 7 Users - Please read this FAQ ***

…Inputs can be either XLR balanced or 1/4-inch TRS. Each of the 1/4-inch TRS outputs is buffered low impedance balanced.

OK… There is no proper instrument input… A normal guitar/instrument input is high-impedance, 1/4" TS.

However, I would still expect some sound, and it might even work perfectly since your guitar has a preamp (an active pick-up wth a battery) and these tend to be lower impedance than a normal guitar pick-up. The TS (2-conductor) plug into the TRS (3-conductor) socket should be OK.

Plug something into the preamp’s headphone or line-output to see if you are getting sound into the preamp. Do you have headphones or ear buds? Or you can plug-in regular “powered” computer speakers or a hi-fi system, etc.

If you are getting sound out of the preamp, then you’ve got a driver or configuration problem, and we can work on that.

Line input for Guitar is Via the “combo” XLR balanced or 1/4-inch TRS…REMOVE pin covers to access 1/4 input…"I was simply disregarding this and both the 1/4’s on the back are monitor outs…but my mistake did however force me to research even further other “troubleshoots” that I am sure I will encounter with my new-to-digital recording experience…thx

A guitar input is a “convenience,” but I don’t know that you absolutely need it. One of our editors routinely used to play his electric into the Line-In of one of our mixers just to hear it play.

As an experiment, I hooked it up to the instruments (with his permission) and if I really hogged down on a chord, I could get the same analog sound level as as any CD, cassette or entertainment system. If my playing style was more civilized/muted, then, yes, I could use the extra boost typical of Guitar Inputs. But even then with a quiet, well behaved external soundcard, it could be made to work.
