Valve Tube Summing Mixer - Analogue Addicts

We can build custom units for you so just drop me a message if wanting something a little different

Here we have on offer a very nice spec one-off build valve and transformer summing mixer. Hand crafted in the UK using some studio/broadcast grade part which include 8 x balanced XLR line inputs each with a top spec Ludahl input transformer. This is the best way to do summing units but due to costs is very rarely found even on high end gear

After the inputs you have an input level control and a PAN control which is a passive summing network feeding a 2 channel all valve amplifier stage. To offer something really special this has the gain stages styled around the classic REDD47 with an EF86 and ECC88 valve on each channel. Super warm and creamy tones which will add to anything you run through the unit and perfect to tame digital recordings when mastering. The outputs then have 2 x high level custom transformer running 2 transformer balanced line outputs.. A couple of nice vintage meters is also great for some visual monitoring of signal levels

A very high spec clean build at a great price considering it has 10 audio transformers and a true high gain valve pre stage

It is very hard to find and summing mixers that utilize full transformer balanced inputs even though this is the best way to build them. The cost to buy these transformers alone is around £1k... the benefit of these is to maintain a fully isolated transformer balanced input on each channel while also allowing you to maybe overdrive individual inputs into transformer saturation and passive summing while not effecting the other inputs. A very unique and creative tool
