Review DOEPFER Narrow Mixer Slim Line Eurorack Used Perfect Circuit

The Doepfer A-138-N Mixer Line is a versatile and high-performance mixing solution designed for Eurorack modular synthesizers. This 8-channel linear voltage-controlled mixer features a compact and sleek design, making it an ideal choice for any Eurorack setup.

Each channel of the A-138-N offers high-quality linear summing with an input impedance of 20kOhms and an output impedance of 1kOhms. This ensures that the mixer maintains the integrity of the signal while providing ample headroom for a wide range of input levels. The mixer can handle inputs ranging from DC to 15V, making it compatible with virtually all Eurorack sources.

The VCA control input on each channel allows for voltage-controlled mixing, enabling users to add modulation and expressive control to their mixer. The mixer also includes an internal VCA for the master output, providing additional flexibility for mixing and routing signals.

The A-138-N features balanced outputs with a maximum level of 14dBu, ensuring a clean and clear output signal. The mixer also includes a 1V/octave attenuator for the master volume, allowing for precise level control. The mixer's power consumption is also low, at only 100mA 12V and 30mA -12V.

In terms of build quality, the A-138-N is known for its rugged and reliable construction. The mixer is housed in a black anodized aluminum panel, providing both durability and a sleek aesthetic. The panel is also equipped with high-quality aluminum potentiometers and silver rotary switches, ensuring smooth and accurate control.

Overall, the Doepfer A-138-N Mixer Line is an essential tool for any Eurorack modular synthesizer setup. Its high-quality design, versatile features, and compact size make it an indispensable addition to any modular setup, providing users with the ability to mix and manipulate their signals with ease and precision.

The Doepfer A-138-N is a 6-channel linear voltage-controlled mixer designed for use in Eurorack modular synthesizer systems. Here are some potential pros and cons of buying this mixer:

1. Linear design: The A-138-N is a linear mixer, meaning that the signal level at the output is directly proportional to the sum of the input levels. This can be desirable for certain applications, such as mixing audio signals or controlling voltage-controlled effects.

2. Versatile input options: Each channel can accept both line-level and instrument-level signals, making it a flexible option for a variety of sources.

3. Voltage control: The mixer includes CV inputs for each channel, allowing for voltage control of the mix levels.

4. Compact size: The A-138-N is a 2U module, making it a relatively compact option for adding mixing capabilities to a Eurorack system.

5. Affordable price: Compared to other 6-channel mixers in the Eurorack format, the A-138-N is priced relatively affordably.

1. Limited channels: With only 6 channels, this mixer may not be sufficient for larger systems or more complex mixing scenarios.

2. No headphone output: The A-138-N does not include a dedicated headphone output, which may be a drawback for some users.

3. No individual channel outputs: Each channel on the A-138-N is summed to the output, meaning that there are no individual channel outputs available.

4. Limited CV range: The CV inputs on the A-138-N have a relatively limited range of -5V to 5V, which may not be sufficient for all applications.

The Doepfer A-138-N is a compact, affordable, and versatile 6-channel linear mixer with CV control that can be a useful addition to a Eurorack modular synthesizer system. However, it may not be sufficient for larger systems or more complex mixing scenarios due to its limited number of channels and lack of individual channel outputs.

If you are looking for a compact and affordable 6-channel linear mixer for your Eurorack system, the Doepfer A-138-N is a strong option to consider. However, if you require more channels or individual channel outputs, you may want to consider other mixer options in the Eurorack format or look into external mixing solutions.
