Has anyone seen the innards of a Touch Tunes jukebox?

...

I don't know what's inside, although I am aware that these days audio power amplifiers can be very efficient (they operate class D -- switching), and that at bass frequencies op-amps are fast enough that some manufacturers do "close a loop" around the subwoofer, measuring the cone's displacement vs. commanded position (the instantaneous input audio); filtering can be readily added as well in such cases.

The end result is that accurate and high-power bass is relatively inexpensive these days.

OK, I couldn't resist Googling this a bit...

Touch Tunes has various different models, but the amps/speakers are apparently from Bose. One web site reads, "These aren't just jukeboxes, they're an awesome, all-in-one sound system! With the help of Bose©, the Touch Tunes Digital Jukebox will blow you away. Powerful amps, speaker, and sub-woofers deliver music like you've never heard from a traditional jukebox."

Not everyone likes Bose that much, but they definitely know how to build audio systems that many people find pleasing.

Interesting article about Touch Tunes pros and cons vs. traditional jukeboxes:

.

...and one can find them for sale on eBay... intriguing... this one has various photos of the innards:

Wow! People actually spend that kind of money to get fooked ?:-)

I have three 100-CD "juke-box" changers tucked away in a closet, with only the controller visible in our great room. I've had them for so many years I don't remember the cost... for me it had to be cheap ;-) ...Jim Thompson

I love to cook with wine.     Sometimes I even put it in the food.

They're mainly aiming at businesses, but I suppose a few really well-heeled folks might buy them for personal use.

I'm surprised you haven't ripped your collection onto a hard drive so that your Roku units could play them all back yet? :-)

The Roku is in my office, so I can listen to Fox Radio ;-)

For serious music listening I retire to the great room and the

7-speaker surround system... I recorded the BBC re-do of the stage version of "Phantom" a few nights ago, and will get out the wine and cheese and watch that tonight ;-) ...Jim Thompson

Probably the same patented "Acoustimass" bass-enhancement technology they use in their home units:

They're essentially Bose products, right? Bose has some sharp people working for them, and they are not all that tied to "things must be flat".

I think the great servo subwoofer craze tailed off a bit after about '05. You can find Velodyne models for cheap on ebay... I expect that subs have just gotten better as people have bought more

5.1 and 7.1 systems...

Thanks to all of you for the info. These links are interesting. I did not know how the songs are stored, retrived, or that a person has to pay extra to get certain songs. The whole thing sounds like a rip-off to me. At the same time, I do think their sound is about the best I've heard.

The ebay link answered a lot of questions. The one we have in the local bar is that same one (Allegro). I noticed that the ebay ad says you cant use it without a contract with Touch Tunes. I bet that could be modified for home use. Actually, I'd just like to get my hands on the speakers and power amp. I can feed it from the over 4000 songs on my computer as well as a cd player, and other input devices, including a record player (yea, I'm showing my age). I was amazed at the small size of the electronics inside. I was expecting a huge power amp with giant capacitors and huge heat sinks. Instead most of that box is full of nothing but air. I wish they showed more of the speakers on those photos, but now I have a better understanding of them.

I noticed the one in the pictures says "Bose" on the front. Next time I get to the bar I'll have to look for that label. Now I know why Bose speakers are always the most expensive. They really got the sound!

Thanks

I am a jukebox operator for the last 25 years. Some brands have very good amplifiers, the Rowe CD jukeboxes like a gentleman was mentioning have excellent sound, if you team the machine up with some good speakers it will reward you with some excellent sound, the floor models have also very well made crossovers and come with rockfordfostgate 12' lows, that will give you a nice lunch. The Digital machines are even better. Now, I have to add, that many locations would take a line out from the jukebox and combine their house sound system with that of the jukebox, you may think it's only the jukebox, but it is getting help from outside equipment.

He may well have found out by now being some 9 years on :_)
