Product Description

The Mixthesizer Custom is a special product designed specifically for synthesizer enthusiasts and professionals who need a versatile, high-quality mixer with a fully analog signal path. After years of development, this mixer is the result of extensive research and innovation, offering unmatched performance and flexibility.

Whether performing live or setting up a studio, this mixer adapts to your needs, ensuring seamless integration with your synthesizers and delivering superior sound quality.

Key Features:

  • Durable and Portable Case
    Available in two sizes (7 or 14 units), the Mixthesizer Custom is built to protect your gear. The lid provides space for accessories such as cables, DB25 to TRS adapters, and even the external power supply.
  • Advanced DB25 Connectivity
    Inputs and direct outputs use DB25 connectors to reduce cable clutter and ensure quick, clean connections – ideal for professional studios and live setups.
  • Versatile and Customizable
    Each Mixthesizer Custom can be configured to suit your exact requirements. Add more AUX sends, extra inputs, or routing options using dedicated units.
  • High-Quality Components
    Powered by a premium external transformer for stability and clean audio. The power switch is placed at the top right for easy access.

Additional Options:

  • DB25 to TRS Adapter: For users preferring TRS connections, a compact DB25-to-TRS adapter fits neatly inside the case lid.
  • Flexible AUX Configurations: Up to 4 AUX sends per channel can be added and routed to your needs using dedicated units.

MMT107 M / MMT107 S – Dual AUX Sends

Both units provide two AUX sends (1&2) per channel and support two operational modes: L and L&R, ensuring optimal use with both mono and stereo effects.

  • MMT107 M (for mono synths):
    L → signal sent to left AUX channel only
    L&R → mono signal split and sent to both L and R – ideal for stereo effects
  • MMT107 S (for stereo synths):
    L → stereo signal summed to mono and sent to left AUX channel – great for mono effects
    L&R → stereo signals sent to respective AUX L and R

This intelligent routing makes it easy to integrate both mono and stereo effects in your setup with total control and flexibility.

Product FAQs

The Mixthesizer Custom is a fully customizable analog mixer designed for musicians and producers who work with synthesizers and analog instruments. It can be configured with up to 64 mono channels or 32 stereo channels, and supports 8 stereo auxiliaries. You can choose various units such as mono/stereo inputs, aux sends, and more to create the perfect setup for your needs.

The DB25 connection in the Mixthesizer Custom is used for faster and cleaner connectivity. This connector allows you to reduce cable clutter by using a single DB25 cable to carry multiple audio channels (usually 8 per cable). It’s perfect for professional setups where you need clean, organized cabling and rapid setup.

You can customize your Mixthesizer Custom by choosing various units, such as:

  • Quad Mono Input (MMT101)
  • Quad Stereo Input (MMT103)
  • Aux Sends for Mono or Stereo Synths (MMT107 M/S)
  • Quad Stereo Subgroups (MMT109)
  • Dual Master Stereo Aux Sends & Returns (MMT111)
  • Main & Sub Out with VU Meters (MMT115)

These units allow you to build your perfect configuration for studio or live performances.

All AUX sends in the Mixthesizer Custom are stereo and can operate in two different modes: L and L&R.

On mono channels:

  • L mode: the mono signal is sent to the L channel of the AUX send.
  • L&R mode: the mono signal is duplicated and sent to both L and R AUX channels.
  • Example: use a stereo effect with a mono synth.

On stereo channels:

  • L mode: stereo L+R signals are summed to mono and sent to the L AUX channel.
  • L&R mode: L and R channels are sent independently to AUX L and R.
  • Example: use a mono effect like a spring reverb with a stereo synth.

You can add up to 4 AUX units per input unit, giving you up to 8 sends per channel (each AUX unit provides AUX 1 and 2).

Depending on the number of AUX units used, you will also need return units:

  • 2 AUX units → 1 MMT111 return
  • 4 AUX units → 2 MMT111 returns
  • 6 AUX units → 3 MMT111 returns
  • 8 AUX units → 4 MMT111 returns

To route channel groups, you can add:

  • MMT109 – Quad stereo subgroup sender (added per channel unit)
  • MMT113 – Octal master subgroup receiver (needed in the master section)

You can choose to apply subgroups to mono channels, stereo channels, or both.

The Mixthesizer Custom supports mono and stereo inputs, aux sends, and direct outputs via DB25 connectors. We also provide DB25 to TRS adapters for flexible integration.

Yes! The Mixthesizer Custom is built into a sturdy case (available in 7 or 14-unit formats), with room in the lid for cables, adapters, and power supply – perfect for mobile setups and live gigs.
