Mode Machines OMF-1 Analog Rack Filter

The Mode Machines OMF-1 is an analog 19″ rack filter designed for use with a wide variety of sources. the preamp in this unit can handle signals from guitar (instrument level) input all the way up to eurorack modular levels.  Far from just a basic Moog ladder filter clone, the OMF-1 adds a tap for the phase reversible single pole -6 db per octave slope (labeled FIZZ) phase reversible 4 pole -24 dp per octave slope(labeled Smooth), as well as extensiv modulation options. Also included in this circuit is a beautiful sounding overdrive. By sending signal into the filter and adjusting the preamp, you can overload the filter core (indicated by a red LED) to add additional harmonic content to the signal.  The OMF-1 features a side chain input as well as CV and Gate inputs for external filter control. The modulation options are Follower (think Mutron bass filter) Attack Release and Attack Decay settings. the LFO has triangle and square waveforms with a rate control and dedicated depth control as well as the ability to self trigger the envelope (which essentially will act like a complex lfo shape).  clocking in £666.00 direct from the mode machines site, this is an impressive all analog rack mount filter that truly has an impressive character.Take a listen to the video for plenty of sound demonstration. take a look at the Manual here

Now that the Circuits have all been Built. we can wire them all together.  This is really quite straight forward. Simply wire everything in parallel. This means that the power wiring for each module goes directly back to the source. This allows us to not have voltage drop across each component.

make sure to leave plenty of extra wire so that you can place knobs and connectors where ever you want in your enclosure.

I will return shortly to show how everything is mounted in the case and give it a nice run through!
