The UralTone REDD.47 is a single-channel microphone preamplifier based on the famous REDD.47 preamplifier of the REDD.51 mixing desks used in Abbey Road studios. The preamp sound can be heard in all recordings recorded at the studio between January 1964 and the summer of 1968. The most famous, of course, are The Beatles recordings.

Specs:

• 1 channel REDD.47 clone
• EF86 and ECC88 (E88CC, 6922, 6DJ8) tubes
• Hammond input and output transformers
• Connections: mic in xlr, line out xlr, power in 5-pin xlr
• Adjustments: 6-step gain + fine gain, 3-step output attenuator, Phantom, input pad, Rumble filter

NOTE: In the first batch, the preamp enclosure (lower part) is unpainted. Hammond was unable to deliver painted ones in a reasonable time.

This product was designed completely for our own needs. Working with various sources; synths, loopers and guitars requires a mixer. A table sized mixer is sometimes way too big. Our vision was to have a good sounding device but not exactly hi-fi. We designed the circuit around a well known MOSFET IC. The sound and simplicity are borrowed from tube circuits. We also added a few nice extras. 

Clipping: Each channel has its' own (soft) clipper switch, which allows distortion on lower signal levels. Before clipping the signal starts to compress. This clipper works in a similar way to using tape compession.
Insert: Needed for various effects. The insert connector allows one to use any guitar or studio effect inserted before the channel volume pot. The insert jack works also as a channel output for example for audio interfaces.
Link: All four channels are linked internally. If a signal is fed to input one, all the rest of the inputs are chained to input one. If channel 1 and 2 are used, channel 1 is used individually and input 2 is linked to channels 3 and 4. This allows parallel signaling, such as clean and distorted channels or different inserted effects for one instrument. Sound: In no way is this intended to sound hi-fi. It is a good sounding, nicely distorting mixer for synths, guitars etc. All channels compress or distort nicely.

In nutshell: The UralTone tube sounding mixer sounds tasty. It is not an uncolored basic mixer, it's an effect of it's own!

For many people the four channels of the Micro Mixer is just way too few, especially considering if it's used with instruments with stereo outputs. To solve this limitation we figured to make an expansion for the Eurorack Micro Mixer. Learn More

From day one, when the original Micro Mixer was published, we got questions about fitting the kit to Eurorack-systems. The original kit did have some extra features added to it's PCB, but due to the option of being battery operated it didn't have enough of space in the enclsoure for these to be added. Now with the space we got from removing the battery option and a bigger front panel, the Eurorack version includes these new features such as alternative 6.3mm input and output jacks, stereo output for headphones, mix bus in for chaining more mixers, selectable aux and aux out, and a switch to select the B output between b-bus and aux-bus.
