Seventh Circle Audio

Hi, it seems obvious what wet/dry do, but I'm still a bit puzzled. I used an oscilloscope and a VST analyzer to calibrate the B16, and I noticed that if I turn the wet/dry knob all the way to dry, the amplitude of the signal goes way up.

This I might expect - if you are mixing a high level (uncompressed) signal with the lower level (compressed) signal, the mix ought to be lower. Theory is fine.

However, what I find very odd is that the level of the dry signal is higher than the bypassed signal level - much, much higher. Further, the gain knob only affects the wet signal - although in the manual it states that the makeup gain applies independently of the compression.

So perhaps I've misunderstood, but I would have thought the fully dry signal would be at the same volume level as the bypassed level. And I also would have thought the makeup gain would apply to the signal no matter the position of wet/dry. At fully dry, turning gain has no effect whatsoever; it only affects the wet signal and therefore only affects levels when I have the wet/dry knob at least somewhat wet.

Have I managed to make a simple statement complicated?

I have 2 B16's and they both calibrate fine, and they both exhibit this behavior.

Thanks in advance any replies.

After more troubleshooting and communicating with Tim, I've returned both my new B16's for his expert assistance. The problems I described shouldn't be happening, and despite rechecking every component on the boards, and replacing the OPA2604's, the issues remained. I'm puzzled; it was a clean build and I took my time.

In any case, I'll try to remember to report back here when I get them repaired, so if anyone else has these issues you'll have an idea what mighht be wrong.

OK, I'm keeping my promise. Tim looked over my B16's and found nothing wrong with them! He said my calibrating was off by 6db, which may have been due to a shorted Pin3 in my testing rig, and he recalibrated it for me. I just tested them today and I'm enjoying them!

Thanks Tim!
