JamHub GreenRoom Silent Rehearsal Studio

The first time we used it, was a very easy set up and within the first song I looked around and my 4 other band mates were all grinning ear to ear, pretty good testimony right there. It sounds really good. very happy with the unit. I would of gave it 5 stars easy if it wasn't for what has been already mentioned in most every review, The reason why I gave it 3 stars, because it has the worst power supply connection imaginable, the first time you plug it in you think, man this is gonna break. It's a 4 pin connector, the weakest type there is, it feels like your plugging into a sponge, loosely. I hope someone at Jamhub sees these reviews. I can't believe they would do this to a otherwise perfect product that is worth every penny you pay for it, to bad. they need to retro fit these units.after a month I have to upgrade my review from a 3 star to 4 star. The unit is really great, great sounding. the power supply might be suspect, but if your careful it should last.The customer service is excellent, nice guys, said if my unit had a problem they would send me another one for free immediately.Up to 5 stars because they read this review and contacted me assuring me they have had no issues with the power supply connection and if I should ever have one a replacement was ready.also you probally will need the headphone extension cables. we gave the ext. control pod to the drummer, everyone else has to move to the unit to adjust their mix. if you could afford it all 7 inputs can get an extension pod so everyone can sit away from the unit, but it isn't needed. keep jammin'

System works well enough, but the power cable will not stay plugged into the unit. It just pops back out. Really shoddy construction.

I've used this for over 2 years now, and while I was excited just like everyone to get this for silent rehearsal sessions, I've had the opportunity to evaluate this over several practice sessions and compare with other audio interfaces which can do routing. Here's the breakdown:Good:> Price, it is the most flexible at doing audio routing at this price level, the no. of input interfaces are quite good, especially when compared with audio interfaces in this price range. This was the most well used piece of equipment by our band, even though it suffers from the limitations below:Bad:> Noisy interfaces, this interface cannot be for any serious recordings, it has probably the worst pre-amps out of all the interfaces we own, and the inputs are not consistent. Some are more noisier than the others.> Flimsy build quality, Cheap plastic construction, not for road and the rubbery surface attracts scratches and dust.> Heat issue, there is no ventilation mechanism and the interface can heat up to a nice roasty temperature, I had to put it over a notebook cooling pad to solve this issueOverall, this interface is good enough for jam sessions only, not for recording band demos or other professional work. That said this interface did allow us to to practice a lot more than before, and eliminated any complaints from neighbors. Great for full band jams when combined with an electronic drumkit.However, after about 1 year of use sitting on a desk (no travel), all channels started experiencing more noise (like a constant bird chirping in the background), but it was not loud enough to interfere with our practice.After about 2 years, channels 1, 2, 3 are completely dead ! no input or output from these channels are audible, however other channels still work, and it has not affected our band practice.So, whether I would buy this interface again for $500 if my current one dies out completely, I would've been 50/50 had it not been for the last 2 incidents, but the lack of quality and robustness really tips my judgement to a no. And we're one of those bands which really need a interface like this. And this review is not because of a bad piece, infact I believe that the piece I got was actually better than the average.

I just had my first band practice with my JamHub GreenRoom, and these are my initial impressions.Pro(s):1. It was simple to use, requiring no/minimal use of the "quick start" guide.2. Practice went later than normal because we didn't worry about the neighbors calling the cops.3. Once I got the hang of using the levels, then adjusting overall volume, it made for an EXCELLENT mix.4. The effects were plenty good for practice, and good enough for recording scratch tracks.Con(s):1. There is no power button. I'm not sure why this bothers me, but it does.2. The power cable connector is flimsy and the cable doesn't "seat" well. It comes out far too easily and doesn't really feel like it's in, even when it is.3. No independent adjustment of effect level per singer. It's not a deal breaker, but I thought I should mention it (see workaround from (4) for why this came up).4. The stereo inputs require purchasing of at least 2 mono-to-stereo adapters in my case. They're only $3 each, but out of the box, you're not ready to go (you can get around this by mic'ing an amp at low volume and using an XLR input but this defeats the silent practice promise).5. No ability to modify volume of the singer on channel 1 independent of his guitar. Workaround would be to use an extra input for vocals, but there aren't that many inputs. The dual-knobs would have been nice here.Verdict:Buy one. The build quality isn't up to snuff for a $500 item so you may have to treat it with a little extra TLC. I'm just not sure that it will last due to the cheap feeling knobs and flimsy power connector. But... even with the gripes I have, I can still wholeheartedly recommend it. Our practice went smoothly, everybody got their mix, my singer LOVED that he didn't have to yell to hear himself, and I could finally hear the bass without shaking my neighbors windows.
