Boogie doesn't "close" all the way?

Author Boogie doesn't "close" all the way?

Exuviae

I tried a search for this, but to no avail...

My Boogie, with cutoff all the way down (ccw) and res all the way down (ccw), still lets a bit of sound through. Never seems to fully "close".

This is regardless of which output is used.

Normal?


MikeHulme

No. It should be completely silent.

I'm no expert, but at a guess, could this be a faulty vactrol?

lag progress posted about leaky 6dB and 12dB

The 6dB out on my Boogie closes after a short gate in but there is a tail of low level signal which fades over 4-5 seconds.
I'm supposing this is not normal behaviour. Any comments?


therk

The 6dB output on mine leaks slightly as well - not much, but it's there. Never really bothered me that much tho...


microfauna

The Malekko product description does say that there might be "bleedthru" from the 6dB out.
I think what I'm experiencing is not a constant low level leaking.


Exuviae

I'll check the outputs again later-maybe even a short vid.


Malekko

The trimpot on the back will make it "close" more


Exuviae

Thanks, Josh!


Exuviae

m'kay, so yes, the trimpot does allow more "closure", however, it is clearly marked that if I move it, Josh will show up at my house and do bad things to me and mine. woah

Well, I did it anyway since he baited me to do so on a public forum. hihi

There is a clear balance here between having the 6db jack close all the way and sacrificing the nice throaty top end sizzle when opening the cutoff all the way...so, I ended up leaving it pretty near the stock setting as I am loathe to lose that lovely top!

All things withstanding, I publicly thank everyone and Josh for sharing the skinny.

How many of you find Borg 2 leaky in VCA mode?

I recall dieter saying that LPG leaking was typical of vactrols.

Currently i think mine is tuned well, since i can push the cutoff higher with CV than the panel pot will go. I wouldn't wish to tune the center frequency down any more.

If its normal to all borgs, cool.


suboptimal

I haven't noticed any bleed at all from the Borg.

Note re Boogie from Grant Richter from a previous thread:

Boogie: Used as a Gate the trimpot on the back is adjust so the 6dB output is at -60dBv for a 100 Hz sine wave with freq and freq env. at zero. This is a compromise, it allows the top end to reach 20kHz and have a lot of "air".

-60dBv was considered a good spec. back in the old days.

By adjusting the trimpot, you can lower the bottom frequency and amount of cutoff at 6dB output at the expense of high end frequency. Busted trimpots are not covered under warranty, so if you don't know what your doing, please don't mess with it.

tried mine out as a LPG on saturday and was pretty underwhelmed by it. it leaks and is just really short. but i wasn't pinging it with a trigger signal - i was using maths in exp mode with rise and fall at CCW

does the CV knob have to be in a particular place when in LPG mode? was sending the maths output into the KEY input anyway, but just vaguely remember mention of the CV control somewhere....

Did you have the peaking all the way to the left until it clicked (and also everything else hard left)? Borg 2 will have less decay than borg1, but 'just really short' sounds like maybe it wasn't all the way into low pass gate.. Different ones have a different ring because of vactrol differences, but you should have a little something something when it's plunked.
it can be trimmed a little to shut down more, but you probably shouldn't be able to hear anything at all when set all knobs hard left.. I trim mine so with the monitors cranked i am just starting to hear something in low pass gate mode with the frequency at about 10:30ish. The control knob isn't up to anything if there is no cv being input at the cv jack.
(also be sure and check it out as a filter with the jumper yanked on the back for some killer resonance).


dude

put it in two bowls of jasmine rice
