A Simple 4 Channels HiFi Eurorack Mixer.

This module is inspired by the Doepfer A-138n and uses some parts of the schematics of the Befaco STMix.

While inspired by those modules, it is better at handling audio signals because of the high quality capacitors it uses on the audio path and the better overall noise filtering.

Have a look on ModularGrid!

The module is available in two different flavors:

• as a DIY kit containing all the required components (build guide available on github)
• as a fully assembled module, ready to use

The DIY kit is not too difficult to build, I would say it's between beginner and intermediate level, check the build guide first to get an idea!

Features

• 4 mono channels with independent volume control
• 1 output
• 1 inverted output
• High quality audio capacitors on the signal path (Nichicon MUSE ES Bipolar)
• Low ESR filtering capacitors on the power path
• 4 HP / 37mm depth
• 5mA +12V / 5mA -12V

This module is designed to mix audio signals with very low noise and distorsion.

Mixing CV signals is also possible but low frequency signals can get distorted in unexpected ways, try it and see if it works for you :)

It's Open Source

I'm happy to sell the module to those who are willing to pay for one, it help supports my modular exploration but I've also made the module open source and all schematics and details are available on Github if you want to build it yourself!

Shipping Policy

In the case of any mistakes or defects in your order, please let me know right away. I'll do my best to make things right.

Assemblies are often built on-demand. Please allow up to a week lead time for all orders containing any custom-assembled items.

Orders can be cancelled anytime before the shipping label has already been generated, in that case a full refund can be issued. Once the label has been generated, the order can no longer be cancelled; it can only be returned for a refund.

Returns are fine as long as they occur within 2 weeks. Please notify me of any returns in advance. A full refund will be issued for all returned items that are received in like-new condition. However, outgoing shipping expenses will not be refunded, and any return shipping expenses will not be reimbursed.

It is the buyer's sole responsibility to safely return any purchased items in order to receive a refund. This includes paying for any return postage and/or shipping insurance premiums. If the buyer decides to refuse a package or designate a package as RTS (return to sender) via the carrier (instead of paying for return postage) there is usually no guarantee that the package will be returned to me in a timely manner, or at all. A refund may not be issued until the items are physically received and inspected. If any return shipping expenses are billed to me by the carrier, that amount will be deducted from any associated refund.

International buyers are solely responsible for any import customs duties, taxes, fees, tariffs, or any other associated costs. These costs will not be reimbursed in the case of a return, and any import costs that I need to pay in order to facilitate a return shipment may be deducted from any associated refund. If a shipment is returned to me because of unpaid import customs fees, the original shipping costs will not be refunded.
