Review DOEPFER 24db Ssi Low Pass Filter New Detroit Modular

The Doepfer A-105-2 24dB SSI Filter, also known as the "Detroit Modular Doepfer Filter," is a versatile and powerful analog filter module that is part of the Detroit Modular Series, a collaboration between Doepfer and Detroit Modular. This filter is based on the classic 24dB Sallen-Key topology, which is known for its thick and warm sound.

The module features six filter types: low pass, high pass, band pass, notch, all pass, and self-oscillating. The self-oscillating mode allows the filter to generate its own tone when no input signal is present, making it a great source of unique and interesting sounds. The filter's cutoff frequency can be modulated via CV input, allowing for expressive and dynamic filter sweeps.

The module also includes an envelope follower, which can be used to control the filter cutoff frequency based on the amplitude of an audio signal. This adds an extra layer of expressiveness and flexibility to the filter. The envelope follower can be configured to respond to either the positive or negative envelope of the audio signal.

The A-105-2 also includes a distortion circuit, which can be applied to the filter output to add harmonics and grit to the sound. The amount of distortion can be controlled via a CV input, allowing for dynamic and expressive distortion effects.

The module's front panel is laid out in a clear and intuitive manner, with all controls and inputs labeled and easily accessible. The module's power consumption is relatively low, making it a great choice for smaller systems or those who are concerned about power usage.

In summary, the Doepfer A-105-2 24dB SSI Filter is a versatile and powerful analog filter module that offers a wide range of filter types, modulation options, and distortion effects. Its intuitive front panel layout, low power consumption, and collaboration with Detroit Modular make it a great addition to any modular synthesizer setup.

The Doepfer A-105-2 24dB SSI Filter, also known as the "Detroit Modular" filter due to its popularity in the Detroit techno scene, is a versatile and powerful analog filter module. Here are some pros and cons to consider before making a purchase:

1. Multimode Filter: The A-105-2 offers low-pass, band-pass, and high-pass filtering modes, as well as a self-oscillating high-pass mode, providing a wide range of filtering options.

2. Resonance: The filter has a high resonance capability, which can create interesting self-oscillating sounds and textures.

3. CV Inputs: The module includes CV inputs for cutoff frequency and resonance, allowing for voltage control over these parameters.

4. Stereo Outputs: The A-105-2 offers stereo outputs, making it ideal for processing stereo signals or creating wide, stereo filter effects.

5. Affordable: Compared to some other high-end filter modules, the Doepfer A-105-2 is relatively affordable, making it an attractive option for many synthesists and electronic musicians.

1. Size: The module is quite large, measuring 21 HP, which may be a concern for those with limited rack space.

2. Power Consumption: The A-105-2 consumes a fair amount of power, requiring 125mA 12V and 125mA -12V.

3. No Attenuators: The module does not include attenuators on its CV inputs, which may require additional modules or patch cables to properly control the filter.

4. No VCA: The A-105-2 does not include a voltage-controlled amplifier (VCA), meaning that users will need to provide their own VCA to control the overall volume of the output signal.

The Doepfer A-105-2 24dB SSI Filter is a versatile and powerful analog filter module, offering a range of filtering modes, high resonance, and stereo outputs. While it does have some drawbacks, such as its size, power consumption, and lack of attenuators and VCA, its affordability and rich sonic capabilities make it an attractive option for many synthesists and electronic musicians. Ultimately, the decision to purchase the A-105-2 will depend on an individual's specific needs, preferences, and budget.

If you're in the market for a versatile and powerful analog filter module and have the rack space and power supply to accommodate it, the Doepfer A-105-2 24dB SSI Filter is a solid choice. Its wide range of filtering modes, high resonance, and stereo outputs make it an ideal tool for creating intricate and expressive filter effects in your synthesizer or electronic music setup. However, be sure to consider the module's size, power consumption, and additional requirements for attenuators and a VCA before making a purchase.
