Quoted from screaminr:A few questions from someone with no soundbar experience .
Does it make a big difference
Does it sound good
Does it automatically pair when you turn the game on
Does it work in conjunction with the back box speakers
Is there a delay
Thanks for any feedback .
I can address these, one at a time...
Does it make a big difference
It makes a difference, but of course YMMV due to differences in brands, sizes, features etc of various sound bars. For example, highdef uses a similar but smaller soundbar than mine, and he is saying that even though his smaller one doesn't have discreet tweeters in it, it sounds good. That's a plus because the one I happened to have lying around is wider than the head of the pinball machine, which looks a bit off. I did just buy a cheap, off-brand soundbar that's 32" to test with as a potential long-term solution. I'll be messing with it later today and if it's any good I'll report back.
Does it sound good
Damn good, but IMO because it is situated above your head it won't be as impactful as other cabinet designs where a high-quality and amplified 2-way driver is installed aside the DMD/LCD display. It is difficult to make comparisons because it isn't a music pin but FWIW my R&M sounds clearer during gameplay. I hesitate to say that if R&M was playing music it would beat the soundbar atop GNR but it's possible. What I can tell you is that when I have the soundbar active on GNR and the volume is up it certainly fills the room. Not sure but that might annoy whoever is nearby playing a different pin. Just food for thought.
Does it automatically pair when you turn the game on
No. When the game comes on the internal cabinet audio is active. You have to hit the button that's on the left side of the coin door to make the change to use bluetooth every time you boot up the machine. You then need to use the BT config menu to select the soundbar as the source to connect to every time. This is something I hope they can add to what's currently in place - namely the ability for it to automatically re-connect to the last-used device if you simply hit the button on the cab.
Does it work in conjunction with the back box speakers
no. if you connect to bluetooth it silences all internal audio.
Is there a delay
Not that I can see/pick up on, no.
Finally, on the topic of splitting the signal coming off the motherboard... a couple of things come to mind which I observed during testing. First off, the intensity of the line-level signal takes a hit when you use a simple 'Y' splitter. The line-level signal also takes a hit when it passes thru the ground loop isolator. (it just does, it's seems unavoidable.) Soooo, when I use a simple Y splitter and configured both halves of the signal to employ a ground loop isolator, I found that it was difficult to get the overall volume to where I wanted it. As another Pinsider mentioned earlier, the better approach is to use a headphone amp with multiple outputs as opposed to the simple Y splitter. They start at about $25 on Amazon, I just don't have one to test with. Of course the point of wiring a soundbar up this way (as opposed to via bluetooth) would be to make it so you could send the signal to the soundbar via an aux input on the soundbar, avoiding the need to re-connect via bluetooth. Be careful though, as many modern soundbars don't include an aux input nowadays. One other advantage to choosing bluetooth for the soundbar connection is that many soundbars also integrate DSPs that expand the theoretically compressed audio being shared via bluetooth. In theory, and with all else equal, for some soundbars it could just 'sound better' if you play it via bluetooth.
