Review DOEPFER 12db Multimode Filter Eurorack New Perfect Circuit

The Doepfer A-121-2V 12dB Multimode Filter is a versatile and powerful Eurorack filter module, designed and manufactured by Doepfer Musikelektronik. This filter offers an impressive range of tonal modifications, making it a valuable addition to any modular synthesizer setup.

At its core, the A-121-2V is a 12dB multimode resonant filter. It features six filter modes: Low Pass, High Pass, Band Pass, Notch, All Pass, and a unique Self-Oscillating mode. The filter can be driven into self-oscillation, producing complex and rich harmonics, especially when the resonance is cranked up.

The filter's input and output levels are individually controlled via attenuator knobs. Both inputs support DC coupling, AC coupling, or high-pass filtering. The DC coupling mode allows the filter to process DC voltages, which can be useful for processing drone sounds or generating complex waveforms. The AC coupling mode is more common for audio processing, as it separates the input signal from the DC offset.

The filter's resonance control is quite expressive, with a wide range of self-oscillation capabilities. The resonance knob can be pushed beyond the self-oscillation threshold, producing complex and saturated sounds. This can be particularly interesting when using the filter in combination with other modules, such as voltage-controlled amplifiers or envelope generators.

The A-121-2V also features a dedicated envelope follower input, allowing the filter to respond to the dynamics of an audio signal or an external envelope. This adds an extra dimension of expressiveness and control to the filter's sound.

The module's front panel is cleanly laid out, with clear labeling and intuitive layout. The filter's control voltage (CV) and audio inputs and outputs are all conveniently located on the right-hand side of the module, making it easy to patch in and out of other Eurorack modules.

The Doepfer A-121-2V 12dB Multimode Filter is a high-quality, versatile, and expressive filter module that is sure to inspire and excite any modular synthesist. Its rich feature set, coupled with its impressive sonic capabilities, makes it an essential tool for exploring the vast sonic possibilities of modular synthesis.

The Doepfer A-121-2V 12dB Multimode Filter is a versatile and high-quality filter module commonly used in Eurorack modular synthesis systems. Here are some pros and cons that may help you decide if this filter is right for your setup:

1. Versatility: This filter offers 12 different filter types, including low-pass, high-pass, band-pass, notch, and all pass. It also includes a self-oscillating mode that can generate complex filter sweeps and sounds.

2. Resonance: The filter has a high resonance capability, which can generate self-oscillation and produce interesting and unique sounds.

3. CV Inputs: The module has separate CV inputs for cutoff frequency and resonance, allowing for greater control over the filter's characteristics.

4. Easy to Use: The module is relatively easy to use, with clear labeling and intuitive layout. It also includes a built-in VCA, making it a complete filter and amplifier module.

5. Durable Build Quality: Doepfer is known for their high-quality build and reliable components, making this a solid investment for your modular system.

1. Size: The A-121-2V is a larger module, measuring 26 HP (height units) in Eurorack format. This may be a consideration for those with limited rack space.

2. Power Consumption: This module consumes 110mA of power, which can add up in larger systems.

3. Complexity: While the module is relatively easy to use, its many filter types and functions may take some time to fully understand and master.

The Doepfer A-121-2V 12dB Multimode Filter is a high-quality and versatile filter module that offers a wide range of filter types and functions. Its self-oscillating capability and separate CV inputs make it a powerful addition to any modular synthesis system. However, its larger size and higher power consumption may be a consideration for some. Overall, if you're looking for a high-quality and versatile filter module, the A-121-2V is a solid choice.

If you're in the market for a high-quality and versatile filter module for your Eurorack system, the Doepfer A-121-2V 12dB Multimode Filter is an excellent choice. Its many filter types and functions offer a wide range of possibilities for creating complex and interesting sounds. However, be sure to consider its larger size and higher power consumption before making a purchase.
