Review DOEPFER Eurorack Miniature Stereo Mixer Standard Color

The Doepfer A-138-s is a compact, yet powerful stereo mixer designed for Eurorack modular synthesizer systems. This miniature mixer, measuring only 19 inches (483 mm) wide, is perfect for those looking to add mixing capabilities to their modular setup without occupying too much precious rack space.

The A-138-s features six mono input channels, each with their individual level control knobs, making it suitable for mixing multiple sound sources. In addition to these mono channels, there are two stereo input channels, allowing you to mix stereo sources with independent level controls for the left and right channels.

One of the standout features of this mixer is its flexible routing options. Each channel offers a pre/post-fader send function, allowing you to route signals to external effects processors or other modules. There are also two return inputs, where these external signals can be mixed back into the main signal path.

The A-138-s boasts a high-quality, discrete Class-A design for its mixer circuitry, ensuring accurate and clear signal processing. It also offers a balanced XLR output for connecting to external recording equipment or PA systems, making it an excellent choice for live performances or studio applications.

The power consumption of this mixer is impressively low, with a maximum current draw of 150mA at 12V and 100mA at -12V. This makes it an energy-efficient addition to your modular system.

The Doepfer A-138-s is housed in a robust, aluminum panel, ensuring durability and longevity. Its compact size, high-quality sound processing, and flexible routing options make it an essential tool for any modular synthesist looking to expand their creative possibilities.

The Doepfer A-138-s is a miniature stereo mixer designed for use in Eurorack modular synthesizer systems. Here are some potential pros and cons of buying this mixer:

Pros:

1. Compact size: The A-138-s is a space-saving solution for mixing signals in a Eurorack setup, as it only requires 12 HP of panel space.

2. Stereo capability: This mixer allows for the mixing of two stereo sources or four mono sources.

3. Flexible routing: Each input channel has a dedicated level control and a switch for selecting between pre- or post-fader routing to the mix bus or the master output.

4. High-quality components: Doepfer is known for using high-quality components in their products, ensuring reliable and accurate performance.

5. Affordable price: The A-138-s is priced competitively compared to other miniature stereo mixers in the Eurorack market.

Cons:

1. Limited features: The A-138-s is a basic mixer and does not offer additional features like equalization, filtering, or other effects.

2. No individual output levels: Each channel shares the same output level control, which may make it difficult to achieve a balanced mix if you have significantly different levels between sources.

3. No headphone output: The A-138-s does not have a dedicated headphone output. If you need to monitor your mix with headphones, you will need to use an external solution.

Conclusion:

The Doepfer A-138-s is an excellent choice for those looking for a compact, stereo mixer for their Eurorack setup. Its high-quality components, flexible routing, and affordable price make it a popular option among modular synthesists. However, its limited features and the lack of individual output level controls or a headphone output may be drawbacks for some users. Ultimately, the decision to purchase the A-138-s depends on your specific needs and preferences within your Eurorack system.

Recommendation:

If you require a compact stereo mixer for your Eurorack setup and are comfortable with its limitations, the Doepfer A-138-s is a solid choice. However, if you need additional features or more control over individual output levels, you may want to consider other options, such as the Intellijel Quad VCA or the Make Noise 12-HP Stereo Mixer.
