Extra Mullet#

Combining buffered mult


The Extra Mullet is the bigger, badder version of the Mullet. It's just as business in the front, but has way more party in the back: an extra 2HP strip mixes inputs for seven outputs that sum combinations of the four inputs.

  • Type: Mult
  • Size: 6 HP Eurorack
  • Depth: 0.8 inches
  • Power: 2x5 Eurorack
  • +12 V: 50 mA
  • -12 V: 10 mA


Power connector

To power your Noise Engineering module, turn off your case. Plug one end of your ribbon cable into your power board so that the red stripe on the ribbon cable is aligned to the side that says -12 V and each pin on the power header is plugged into the connector on the ribbon. Make sure no pins are overhanging the connector! If they are, unplug it and realign.

Line up the red stripe on the ribbon cable so that it matches the white stripe and/or -12 V indication on the board and plug in the connector.

Screw your module into your case before powering on the module. You risk bumping the module's PCB against something metallic and damaging it if it's not properly secured when powered on.

You should be good to go if you followed these instructions. Now go make some noise!

A final note. Some modules have other headers -- they may have a different number of pins or may say "not power". In general, unless a manual tells you otherwise, do not connect those to power.


Illustration of Extra Mullet's interface

In L-4
Extra Mullet has four circularly normaled input jacks (left side of module). LEDs light up when a signal is received.
Out L-4
Each input has two outputs. Because inputs are normaled, if no input is plugged into an input, outs flow from input above it.
Extra outs
Extra outs combine inputs additively. Extra Mullet is set up so that there are seven unique combinations of inputs. These function on both gates/triggers and on CV inputs.

Input & output voltages#

Extra Mullet's inputs and outputs are rated for -10 V to 10 V.

Patch tutorial#

First patch
Plug a CV source into any input. Patch the Out to CV-in on a module you would like to modulate. Now instead patch one of the Extra outs: note how these signals differ because the normaled signal is added in the Extra outs. Next, plug multiple CV sources into Extra Mullet inputs. Patch Outs to CV inputs on a module you would like to modulate. Patterns will differ as the different inputs are summed.
Using Extra Mullet with gates
Plug up to four gate inputs into Ins. Patch any combination of Outs and Extra outs to modules for interesting variety in rhythms. (Note that a single gate in, while still additive, will not result in different patterns for the combined outputs.)
Using Extra Mullet with CVs
Plug up to four CV inputs into Ins. Patch any combination of Outs and Extra outs to modules for up to 11 versatile CV outs.
Using Extra Mullet with a combination of CVs and gates
Because Extra Mullet performs simple summations, it can be used with any combination of inputs (although summation of pitch CVs is not necessarily recommended as EM is not calibrated for this use). You can mix and match CV and gate signals for unique output patterns on extra outs.

Genesis & design notes#

The original module started when Noise-E friend Shawn Jimmerson informed us that we needed a module called "The Mullet." It was pretty clear that that could only be a buffered mult. A few years later, we realized (with Kris' growing obsession with CVs) that it would be pretty simple to give the Mullet a lot more bang for its buck. I mean, if you're going to have a mullet, you should go all out, right? And the son of the mullet, Extra Mullet was born.


We will repair or replace (at our discretion) any product that we manufactured as long as we are in business and are able to get the parts to do so. We aim to support modules that have been discontinued for as long as possible. This warranty does not apply to normal wear and tear, including art/panel wear, or any products that have been modified, abused, or misused. Our warranty is limited to manufacturing defects.

Warranty repairs/replacements are free. Repairs due to user modification or other damage are charged at an affordable rate. Customers are responsible for the cost of shipping to Noise Engineering for repair.

All returns must be coordinated through Noise Engineering; returns without a Return Authorization will be refused and returned to sender.

Please contact us if you think one of your modules needs a repair.
