Is there a difference in how the Compact has been put together? I have an older model, maybe 2 years old and when I put it right next to a brand new unit, the volumes are dramitically different. If the gain on the OLD compact sits at 12 o'clock, to get a match sound from the NEW Compact, the gain needs to be set to nearly 3'o'clock.

I thought I had a faulty unit, Bose very kindly sent me a replacement, but the replacement is exactly the same. So either the OLD Bose is faulty (if being too loud is faulty?) or there's been some change in the way the gain control is configured.

I really appreciate Bose helping me when I thought I had a fault. I only had one other Compact to compare side by side with, and that one had been working fine. The NEW Compact also works perfectly, I just had to set the gain higher to get the same volume. I'll never need to run it with the gain at full whack anyway, ever, so it's not an issue.

And yes, I've checked the source, different signal cables, mono vs stereo, jacks, RCA, (both in and out), flicked the tone match switch a few times etc.

Hi Nick, Tom

I found this discussion - note Neil's comments below Tom's.

I bought another Compact a month ago but hadn't used it up until today. I decided I'd A/B them by taking the new one out today on a couple gigs that I play very often after reading this thread. I noticed a couple differences with the new one.

For one I had to use different levels than I usually use. Channel 1 on the mic had to be turned up past 11 o'clock where I usually go just past 10 o'clock on my older Compact. This is a fairly negligible difference that I've seen on my Classics as well. I also set channel 2 slightly lower than I usually set it - again negligible.

For two EQ was a little different. I set the mic flat instead of turning down the highs to 10 o'clock which was a pleasant surprise. It seemed the mic was less shrill through this newer unit as well. The guitar in channel 2 was a little less bright as well which was okay by me.

So overall there was little difference with the new one, but it was discernible. Again I've seen slight differences in my Classics & Model II's, but I thought I'd share what I found today relative to this thread. I have access to one other new unit that I will test at some point as well.

I can see how it could be possible that there could be subtle differences in the position of the level controls between early and newer production units, but this variance should be very small. We did receive some initial comments that suggested that the system got loud very quickly, therefore the pot taper on the newer units is slightly different.The amount of useable volume remains unchanged and there were no adjustments to the tonal balance of the system.

I hope this helps.

Not sure if this is "slightly different". However, 2 ina row have this sort of difference compare to the old unit.

I'm a little embarrassed as Bose have swapped this unit over, however I did all the troubleshooting. I assumed it was faulty as there was nothing wrong with the cables, source, etc. I guess nobody at Bose NZ/Oz thought this could be the issue...?

Either way - it works, I just have to turn the volume knob up higher to get the4 same sound. Not a big deal, I'm just sorry I wasted everyone's time at Bose.
