BugBrand Matrix - 6x4 banana matrix (standalone)

Post by BugBrand » Mon Feb 17, 2020 10:14 am

Thought some of you might enjoy the sight of this:

Of course I build in Frac format, but will be doing some of these as cased / standalone - perhaps a nice addition to your banana world?

6 inputs / 4 outputs - each control has centre-off switch for polarity/mute.
Linear pots, high quality opamps, 0.1% resistors.

Not on my site yet but - £300 as module, £345 cased - & there's some talk in the bugforum
The case has, on the back, a 12V DC input (internal DCDC generates +/-15V) and common 0V connection on black 4mm banana socket.

Edit - I got asked a question earlier and thought the info would be pertinent to update here. The question was about using this with something external, eg. Flower Electronics box that runs off 9V (+/-4.5V) - if sources from the FE box were summed, would the output go above the limits of FE voltages? The answer is yes - the matrix output can swing to near the +/-15V rails, so if for example you summed two +/-4.5V LFOs they could potentially have peaks of +9V. I guess this might be something to bear in mind when considering usage with machines that run of voltages other than +/-15V. There could, of course, be ways to limit voltage swings via cable modifications etc, but as standard do be aware that the Matrix is capable of producing approx +/-14V (need to double check the exact figure)

Absolutely gorgeous, Tom!

I will be grabbing one for sure.

They look beautiful standalone like that. Definitely want one!

Thinking about getting one of these to mix the cv's of two easels, anyone here know if I'm bound to run into any issues with this?

Beautiful!
Does it have a lttle gain built in or is it unity gain?

I said to C that I believe this will be all good as both Bug & Buchla 200 are +/-15V --- I noted caution on 200e series due to, I think, them not accepting negative voltages.
Very curious to hear further comments & confirm my thoughts.

& Mister Lou - unity gain here. Inputs are buffered then fed to the 6 columns with summing to +/- buses for each output row.
You could add gain by patching an input onwards to a 2nd input.

I'm going to try one in a 2Frame setup to act as an output mixer with 2 aux sends - ie. using as an audio mixer.
Fully DC coupled, happy with CV or audio work.

Mixing Serge and Bugbrand system sounds through the matrix -
