Stupid questiion of the year. How do you use this and what do you use it for?

For starters, I am an electrical engineer so I won't be giving you any hocus pocus, here, but I'll try not to be too technical. The main "real" reason you might use a separate amplifier for your headphones would be to isolate the source from the varying impedance of the headphone sound transducers. Output amplifiers for headphones (or any speaker) can be weak and a stronger amplifier will be more resistant to that varying impedance. Also, a stronger amplifier can usually produce a larger signal without clipping, which is when the output voltage (or current) reaches the maximum voltage (or current) the amplifier can supply. That is really the only technical reason to use an external amplifier. A second reason to use an external amplifier is because the amplifier might change the sound in a way you find pleasing even though it may be less accurate. Tube amplifiers tend to have higher harmonic distortion than transistor amplifiers but also tend to produce more even order harmonics which sound less harsh (or so I've read). When tubes are driven to their maximum, they tend to produce less objectionable distortion than transistors for a similar reason. But really, the main reason to buy one of these and put it on your desk at work or wherever is because it looks cool and people will ask you about it and then you can tell them all kinds of things either true or made up about why you use it.

It is a headphone amplifier......you plug in the headphones...and then you have a minijack for feeding in an IPOD...You can use virtually any device that has a headphone output.....This little amp will boost the output and tonal quality immensely. I have the version with the 3 band EQ...but it works the same way. The vacuum tube ispart of the amp circuit...and it warms up the signal....similar to the higher priced audiophile tube powered amplifers.

It can serve two purposes. If you don't have a headphone jack on your stereo you can plug one of the outputs (Aux, Line e.g.) from the stereo in to it and then be plug the headphones in Bravo Audio. If your stereo has a headphone jack this device can make a noticeable difference in the sound of your headphones if you plug one of the outputs of your stereo. (Aux, Line e.g.) in this device and then plug in your headphones to it. Hope I answered your question.

Sorry, I wish I could answer this one but I'm such a tech idiot and only used this for the very basic purpose :(

Honestly I don't really know how to use the entire thing because the one I'm selling is unused. You should try to youtube it.

I am not sure of the option as I never had the opportunity to use it because it does not work at all. In addition I threw it away so I don't have the manual to revisit...

It's a waste of time. It basically gives you a graphical interface to the audio settings in the head unit so you don't have to wade through the menus when you equalize the settings for different situations or types of music. It's a geek fest with little utility. You can save the settings, so that you can reload them, (nice if you disconnect the battery and erase the head unit) but you have to have a good signal on your phone or it won't work. The app locks out changing settings if the vehicle is moving, and is extremely unreliable, so it often senses movement even when there is none, and prevents any changes anyway. I personally set up my system when I installed and and have never touched it again. I'm not sure why you'd want to keep tweaking it.

We actually did not use it. We ended up giving it away because it was broken. Sorry I'm no help.

Can not answer. Your question since, I had never gotten the opportunity to use it.

I only used it once when I got it last year but I believe just buy turning if off and then on again it reverses direction.

I have had very little luck in figuring out how to use this item for anything. I give it zero stars.

I don't no. I gave it away not to long after I purchased it because it didn't have the functionality I was looking for. Sorry!

reply to D.ThomasIt is not dumb to ask that, cause I just had to look it up myself..lol So here is what I found on it..Technical Info..http://www.qamtuner.com/laments terms and more info. from people using them..good link here below. hope it helps you! Help me understand it better. (smile)http://forums.afterdawn.com/thread_view.cfm/248819

Dunno, but there is a lot of info in the owner's manual. I haven't figured out how to use all the features yet, and I've had it for a year.

I haven't been able to make use of this object. I thought I would be able to, but I do not have the technical know how. I need help with it myself. Sorry I can't be more helpful.

If you have an old one, just use that. if this is a new item for you, then not sure. trial and error I guess. Sorry not much help.

The answer to your riddle is:NO, it doesn't work period. Biggest piece of crap I have ever purchased.

I never used it. It was not what I thought it was going to be so sorry I can't help you.
