So I switched out my 18" cannon kick for my 16" tom-kick. It was sounding fine on it's own but during practice I quickly realized that the kick sound was lost in the mix. I spent about 30 mins messing with presets, B2 levels , difference mics, and nothing helped. It seems that there is some sort of hard limiter with the B2 bass module. With very soft taps on the kick, the bass is quite loud and punchy, but once I bring it up to performance levels, the overall bass level seems to drop off. I figured this might be due to the fact that the 16" drum isn't producing enough low end and more of a mid slap. So I hauled out my 22" masters kick and although the bass from the B2 sounded a touch bigger, it was the same story. The harder I hit, the less overall bass. So today after re-arranging my kit I switched back to the 18" busking kick. Using this kick, the bass output is MUCH higher to the point where it's shaking things off my desk (using the exact same preset). Now the common factor with all these drums is that the resonant head is not ported leading me to a conclusion.
I noted that I could get the kick gate behaving properly with my other kicks, as they are standard drums with sealed heads. It seems the air pressure applied on the resonant head is more than enough to trigger the kick gate even with 16th notes, yet it seems to be putting too much signal/low end into the mic causing some part of the L1 system to limit the overall bass output. Keep in mind I set the trim to where it's flickering red, and back it off a touch, so I'm not overdriving the preamp.
So my sealed kicks provide too much air pressure, and the busking kick doesn't provide enough. My only thought is to try a ported resonant head once my new 18" kick comes in. Although I don't prefer ported heads, if it will allow me to use the kick gate, and provide a dynamic level of bass output I will make the switch.
In the mean time, I've moved the position of the L1 in the room to the back corner behind me. Hoping having it in the corner will help build up some bass frequencies to better fill the room. Seems to be working so far.
If anyone has any suggestions I would appreciate it. I recently did a full firmware update on the B1 and power stand. It corrupted one of my scenes, leading me to believe something might have gone wrong in the update process, or perhaps a bug in the latest version of the software? Not really sure at this point. This L1 might become a vocal only PA pretty quick here.
P.S. Feature request for new iterations. Make the sub level controllable on the mixer PLEASE
