Review DOEPFER Inverting Interrupting Mixer Janus New Detroit

The Doepfer A-138j Inverting Interrupting Mixer "Janus Detroit" is a versatile and powerful modular synthesizer mixer designed by the renowned German manufacturer Doepfer Musikelektronik. This mixer, named after the two-faced Roman god Janus, represents the perfect solution for those seeking to combine multiple audio sources in a flexible and dynamic way.

The A-138j is an inverting 12-input mixer, meaning that each input channel has an inverting switch to invert the polarity of the signal. This feature is particularly useful when dealing with complex signal routing and phase alignment. Each input accepts a voltage control input (VCA), allowing for dynamic mixing and level control.

The mixer offers an interrupting function, which enables the user to temporarily mute or route an individual input to any of the output buses. This feature adds a significant layer of creativity and flexibility to the mixer, allowing for dynamic and evolving soundscapes. Furthermore, the A-138j features a DC-coupled summing bus, allowing for the routing of control voltages and modulation signals.

The A-138j's front panel is equipped with 12 input channels, each with a level control knob, an invert switch, and a DC input for voltage control. The mixer also features a master volume control for the output buses, as well as a separate output for the bypassed input signals. Additionally, the mixer is housed in a robust and compact 3U rackmount case, ensuring a stable and reliable performance in any modular synthesizer setup.

The Doepfer A-138j Inverting Interrupting Mixer "Janus Detroit" is an essential tool for any modular synthesist seeking to explore complex signal routing, dynamic mixing, and creative sound design. With its versatile features and robust construction, this mixer is sure to become a valuable addition to any modular synthesizer system.

4. CV Control: The module provides CV control over the mixing levels, allowing for dynamic and expressive performances.

5. Compact Size: The Janus Detroit version of the A-138-J is more compact than the standard version, making it a better fit for smaller modular systems.

Cons:

1. Limited Number of Channels: Six channels might not be enough for larger modular systems or more complex mixing scenarios.

2. Power Consumption: The A-138-J consumes a significant amount of power, which can be a concern for some users.

3. Price: The module is relatively expensive compared to other mixer modules in its class.

Conclusion:

The Doepfer A-138-J Inverting Interrupting Mixer Janus Detroit is a high-quality and feature-rich mixer module that is well-suited for modular synthesizer systems. Its flexible mixing capabilities, unique interrupting feature, and CV control make it an attractive option for sound designers and musicians seeking to create complex and expressive sounds. However, its limited number of channels, power consumption, and high price might be drawbacks for some users. Ultimately, if you require a mixer with these specific features and have the budget for it, the A-138-J is an excellent choice. If you need more channels or prefer a lower price point, you might want to consider other options.

Recommendation:

If you are looking for a versatile and feature-rich mixer module for your modular synthesizer system and have the budget for it, the Doepfer A-138-J Inverting Interrupting Mixer Janus Detroit is a strong recommendation. Its unique interrupting feature, inverting functionality, and CV control make it a valuable addition to any modular setup. However, if you need more channels or prefer a lower price point, you might want to consider other options such as the Make Noise 0-Coast or the Intellijel Quad VCA.
