The Eowave Flying Attenuator is a passive attenuator which you simply connect between two patch cables, allowing you to control the volume or modulation depth of the signal flowing through it.

It is simple, lightweight and can be “floating” – supported by the connected patch cables themselves. In fact, this design is not dissimilar in to the volume control you might find on some headphones cables.

Although quite basic, attenuators are extremely powerful in a modular system.

They are especially useful for adjusting the depth of control voltages going into modules that lack CV attenuators, and can even be used to reduce the high output level of the audio signals produced by your modular when connecting into external equipment (such as effects pedals, mixers, audio interfaces etc..)

This product allows you to attenuate signals without using up valuable case space, and is extremely cost-effective. There is a *tiny* amount of assembly involved, much of which is not essential (see below)


The mini pot needs to be inserted into the unit when you receive it. Just pop it into the X-shaped slot and you’re away!

You can simply leave the “logo section” (the upper section of the unit with the Eowave logo on) attached and use it as is. You could even use the hole in the logo section to hang the attenuator on a small hook or screw, out of the way of your patch.

(Please note that we take no responsibility for any damage caused during these processes)

OPTION 1 – Make it smaller:

  • Remove the mini-pot to avoid damaging it during this process
  • Snap off the upper “logo section” and then simply discard it, in order to make the unit smaller (It takes a little bit of force to snap these apart, but should be possible without any tools)
  • Re-insert the mini-pot.
  • Get busy attenuating!

OPTION 2 – Use the logo section to create a top cover for the unit (the attenuator works just fine with the sockets exposed , but the option below is there if you want it):

  • Snap off the upper logo section and then fit it over the top of the main section, so that the minipot pokes through the hole (make sure the >IN/OUT> labels on the logo section are orientated the same way as the IN/OUT markings on the PCB itself)
  • The sockets are then enclosed in a PCP “sandwich”, with the logo section forming the top cover.
  • If you like this idea, some kind of adhesive is now required to secure the logo section to the top of the sockets. Make sure you do this with the mini-pot in place, so the two sections are aligned correctly.
  • We found that using two small pads of double-sided sticky tape – attached to the underside of the logo section – worked perfectly, and also allowed for removing and re-aligning it if required. The tape we used was actually carpet gripper tape, but other reasonably-strong options should be fine too. Double-sided sticky foam pads would also work.
  • A tiny amount of glue suitable for PCBs or plastics could also be used, although you would need to ensure it does not run down into the socket and damage it by adhering to the metal contacts (use at own risk!!)
