T1 Lower Kick Gate Threshold?

Hello Everyone! 

So a friend of mine has lent me his T1 Model II, and I'm actually digging it. We are using it as the sole amplification system for vocals in my extremely small jam space, and the compact size is amazing compared to my old 2X15 powered cab setup. Anyhow! Just last jam the bass player said he has trouble hearing the kick. I understand why as I use an 18X8 since there is no room to setup a proper size. I had the briliant idea to hook up my Beta 52A to the L1 just to boost up the kick a little bit. I set it to general kick mic, and put it on kick gate regular and wow! sounds great! The issue however is that the lowest the threshold will go is -20. I tested the threshold on the regular gate and I need to to be around -33 to -35 to pickup the quieter hits. So right now I have the gate to set to maxium speed, and -35 on the threshold. It sounds fine, but looses all definition when I do doubles. I'm curious if there is any way to lower the threshold on the kick gate, or to create a custom preset in the software and import it? I'm 100% new to Bose stuff, so any help would be great.

Hi Boy_narf,

We can't change the parameters of the Kick Gate. Have you tried tweaking the input trim. You might be able to increase the sensitivity by raising the trim. 

Is it possible to take a link out from the amp instead of using the microphone?


HI Boy_Narf,

I'd try turning up the trim a little. Flashes of red are okay. Solid red is not.

Sorry for my typing, I meant to type "take a line out of the amp".  Is there a direct line out from the amp? I'm trying to take the microphone out of the signal chain to see if that will help.



Just tried lowering the sensitivity but unfortunately it's still not enough. There are also a few sections where I feather the kick drum and the gate won't let it through.

I'm curious if anyone has had success making their own Kick gate using EQ and the standard gate? Any suggestions would be great! I tried making my own, but the standard gate doesn't seem to close up quick enough. 

Hello Everyone,

Just wanted to give a bump to this thread. I just got a subkick and resumed testing of the kick gate. Of course while the fast kick gate sounds AMAZING, it doesn't have enough threshold control. It seems to close too slowly not letting doubles through, and doesn't pickup light hits.

Right now I have it set to a regular gate, and am using the utility tone print for 50hz/5000khz. It seems to be a touch tighter than the regular kick prints. 

Does anyone know what is happening with the kick gate preset? I'm assuming it's a gate and EQ all in one. Has anyone had luck making their own Kick gate using the onboard effects? 

I'm also still on the T1, so I'm wondering if the T4 or T8 the ability to further tweak the gates? I'm looking for a reason to get the T8, now that I have an L1M2.



P.S. Although a bit of a round trip, would it be possible to feed a touch more level to a kick gate if I say, plugged the kick mic into channel 1 (setup with a kick print and possibly a compressor), took the output from 1 and fed it into channel 2 (Kick gate would be enabled on this one)? Does this kind of thing work?

Ah well, I did some experimenting with my 16" gigging kick and would you believe it? no mis fires. Guess it's the nature of the "cannon" drum travel kick to not have enough air pressure on the reso head to trigger the gate properly. Very interesting. I've got a proper 18" kick on order so I shouldn't have any more trouble.

Reporting in!

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
