Review DOEPFER Matrix Mixer New Detroit Modular

The Doepfer A-138m Matrix Mixer is a versatile and powerful mixing solution from Detroit Modular, a sub-brand of the renowned German synthesizer manufacturer Doepfer Musikelektronik. This 16-input, 8-output matrix mixer offers a high degree of flexibility and creativity for both live performances and studio applications.

The A-138m features 16 individually controlled input channels, each with a dedicated volume control. These channels can be routed to any of the eight output buses using a 16x8 matrix of rotary switches. The matrix can be configured in various ways, including series, parallel, or cascade connections, allowing for complex routing and mixing possibilities.

Each input channel also includes a mute switch and a signal present LED, providing easy visual feedback and control. The mixer's robust construction is evident in its solid aluminum front panel, which not only looks great but also ensures durability for years of use.

The A-138m operates on /-12V power rails and features low-pass filtering on all inputs, helping to eliminate any unwanted high-frequency noise. It is also 100% CV/Gate controllable, making it a perfect addition to any modular synthesizer setup.

Detroit Modular's attention to detail is evident in the A-138m's design. Each rotary switch is smoothly damped, ensuring precise and reliable operation. The mixer's layout is intuitive and user-friendly, making it easy to navigate even during live performances or in the heat of the moment in the studio.
