Review DOEPFER Interrupting Mixer Module Eurorack

The Doepfer A-138i Interrupting Mixer is a versatile and essential module for any Eurorack modular synthesizer setup. This 6-channel mixer, designed and manufactured by Doepfer Musikelektronik, allows you to blend and balance audio signals from various sources.

The A-138i is an upgraded version of the original A-138 mixer, featuring an interrupting function. This means that each channel can be individually muted by pressing a dedicated button, allowing for dynamic and expressive performances. The muting function can also be controlled via CV input, providing an additional layer of control in a live performance setting.

Each channel on the A-138i offers an input impedance of 20kOhms, ensuring optimal signal transfer from various audio sources, including other Eurorack modules, external gear, or record players. The module's gain control potentiometers offer a smooth and precise response, enabling you to adjust the level of each channel to your desired balance.

The mixer's output level is controlled by a master volume knob, which is conveniently located at the top of the module. This allows you to easily adjust the overall output level to your desired volume or to compensate for any drastic level differences between your input sources.

The A-138i's rugged aluminum front panel is not only visually appealing but also provides excellent protection for the internal components. The module measures 12 HP and features a standard Eurorack power consumption of 125mA ( 12V) and 115mA (-12V). The Doepfer A-138i Interrupting Mixer is an indispensable tool for any modular synthesizer setup, providing the user with a flexible and creative solution for blending and manipulating audio signals.

The Doepfer A-138i Interrupting Mixer is a versatile and powerful mixing solution for Eurorack modular synthesis systems. It offers several unique features that make it an attractive option for many synthesists. Here are some of the pros and cons of buying this module:

1. Interrupting Mixing: One of the most notable features of the A-138i is its interrupting mixing capability. This allows you to mix signals in a unique way by temporarily overriding the current mix levels with the level of an incoming signal. This can create interesting and dynamic sound textures.

2. Mids and Lows Filtering: Each channel on the A-138i includes a low-pass and a high-pass filter, which can be used to shape the sound of the signals being mixed. This adds another layer of sonic manipulation and flexibility.

3. CV Control: The A-138i offers CV control over the mix levels, allowing you to modulate the balance between different signals in real-time. This can be useful for creating complex and evolving soundscapes.

4. Compact Size: The A-138i is a relatively compact module, making it a good choice for those with limited space in their Eurorack system. It measures only 12 HP wide.

5. Affordable Price: Compared to some other mixing solutions for Eurorack, the A-138i is relatively affordable.

1. Limited Channels: The A-138i offers only six channels, which may not be enough for larger systems.

2. Limited Input Impedance: The input impedance of the A-138i is relatively low, which may require the use of attenuators or preamps to get optimal results.

3. No VCA: The A-138i does not include a VCA (Voltage Controlled Amplifier) on each channel, which means that the output level of each channel must be set manually.

The Doepfer A-138i Interrupting Mixer is a versatile and powerful mixing solution for Eurorack modular synthesis systems. Its unique interrupting mixing capability, along with its low-pass and high-pass filters, CV control, compact size, and affordable price make it an attractive option for many synthesists. However, its limited number of channels and low input impedance may be a drawback for some. Ultimately, the decision to buy the A-138i will depend on the specific needs and budget of the individual synthesist.

If you are looking for a unique and versatile mixing solution for your Eurorack system and have the space for a 12 HP module, the Doepfer A-138i Interrupting Mixer is definitely worth considering. Its interrupting mixing capability and low-pass and high-pass filters offer a lot of sonic manipulation possibilities. However, if you require more channels or higher input impedance, you may want to consider other mixing solutions.
