This sale is for a 1u rack front panel which has 2 x Haufe input transformers and a multi way diode clipping circuit. Haufe 191/6 were from broadcast mixers and would have been used as lower level balanced inputs. As such they are great for easily saturating over 0db without requiring lots of gain to drive. When run at lower levels you get a very nice clean sounding tone which soon starts to core saturate with the low frequency as levels are increased. You can switch this to bypass "OFF" the clipper circuits leaving transformer only on select between vintage Mullard Germanium, Scottky, Silicon or LED diodes. Each with its own character and crunch amount. To help fine tune this there is also rotary control to set drive level to the diodes. Allows you to find some nice spots and sort of a blend control.

Totally passive design so no power required to run. Simply run the outputs to any make-up gain stage for for loss recovery as required.

• 2 x vintage Haufe 191/6 transformers
• 1/4" gold plated made in England balanced TRS in/out connections
• Multi way diode clipping control
• Diode level clip control
• 1u front panel as shown

1. Diodes off using just the transformer in the signal
2. Vintage Germanium diodes  -  Classic very rounded signal and huge crunch/clip at lower levels
3. Shottkey diodes - Very similar to the Germanium but with a faster speed
4. Silicon diodes for a more modern squarer sound
5. LED requiring a higher level to trigger the "threshold" - Selected LEDs for lower trigger level
6. Diodes off using just the transformer in the signal 

When switching the diodes into the chain you will get some serious clipping, distortion and compression so you will then require some make-up gain in your next stage.   Very unique unit offering a nice clean transformer sound to dirty and crunch!!

• XLR line inputs - Balanced
• XLR line outputs - Balanced
• 2 x large high level transformers 600 ohm - Made in England
• 6 way diode control selection
• Diode level drive to fine tune from low saturation to high 
• Balanced input and output - 600 ohm
• 19" rack mount

I have seen similar to these being used for mastering and with great results too
Also available as a diode clipper only without transformers if required.  Lower cost option

The idea here is to "change" and colour signals. Each unit we build will have unique specs and workings so a great way of getting unique changes to recordings.  These are designed to handle quite high levels before maxing out so can sound very clean too and are also perfect as hum eliminator and balanced to unbalanced, unbalanced to balanced convertors

The Diodes when saturating also act like a compression reducing the line level outputs.  Each type type is different so you will want to get some gain back from you pre/interface as a make-up stage
