Review MACHINEROOM Dual Vcf Ladder Lowpass Filter Eurorack New Perfect Circuit

Introducing the Machineroom 204D Dual VCF Ladder Lowpass Filter, a versatile and high-performing Eurorack module that brings an essential analog filtering component to your modular synth setup. This filter is a dual-voice version of the classic voltage-controlled filter (VCF) design, popularized by the venerable Moog Ladder Filter.

The heart of this module is its ladder lowpass filter design, which provides warm and rich analog character to your audio signals. Each voice offers separate inputs for voltage control frequency (VCF), envelope or LFO, and resonance, allowing for a wide range of sonic possibilities. The VCF input accepts signals up to 12V and -5V, providing ample control over the filter's cutoff frequency.

The resonance control knob adds self-oscillation capabilities to the filter, enabling you to generate complex and evolving sounds. With a maximum resonance setting, you can push the filter into self-oscillation, creating a wide range of tonal textures and experimental sounds.

The Machineroom 204D features a robust and durable design, with a black anodized aluminum front panel and high-quality, through-hole components. The module's Eurorack format (35HP width, 25mm depth) makes it easy to integrate into your existing modular synth setup.

The filter's outputs offer both attenuated and unattenuated versions of the filtered signal, ensuring compatibility with a wide range of modular synths and other equipment. Additionally, the module includes a DC power input, accepting 12V or 15V power supplies to provide the necessary voltage for optimal performance.

The Machineroom 204D Dual VCF Ladder Lowpass Filter is an essential addition to any Eurorack modular synthesizer setup, offering the classic analog character and versatility of a ladder filter design in a dual-voice configuration. Explore a world of sonic possibilities with this powerful and expressive filter module.

The Machineroom 204d is a dual Voltage Controlled Filter (VCF) ladder lowpass design in Eurorack format. This filter offers several unique features that can make it an attractive addition to a modular synthesizer setup. Here are some of the pros and cons of buying this filter:

1. Ladder filter design: The ladder filter topology is known for its characteristic sound and resonant behavior. The 204d offers two independent channels with this classic design.

2. Voltage controlled: Both cutoff frequency and resonance can be controlled by external voltage sources, allowing for dynamic and expressive filtering.

3. Dual filter design: Having two identical filters in one module can be useful for various applications such as creating complex filtering schemes, stereo processing, or sub-oscillator routing.

4. Sync input: Each filter channel features a sync input, allowing for syncing the filter cutoff frequency to an external clock source.

5. CV attenuator: The 204d includes a CV attenuator for each filter channel, which can be useful for managing the input levels of control voltages.

1. Power consumption: The Machineroom 204d consumes 14 HP and requires a 12V and -12V power supply, which can make it a significant power draw for a single module.

2. Size: With its 14 HP width, the 204d may not be the most space-efficient filter option for smaller Eurorack setups.

3. Limited filter types: The Machineroom 204d is a dedicated lowpass filter, and it does not offer other filter types like bandpass, highpass, or band-reject.

The Machineroom 204d is a high-quality, versatile, and expressive ladder filter solution for Eurorack modular synthesizers. Its dual filter design, voltage control capabilities, and sync functionality make it an attractive option for various applications. However, the power consumption and size may be drawbacks for some users. Ultimately, the decision to purchase the 204d depends on the specific requirements and limitations of your modular setup.

If you're looking for a high-quality, versatile ladder filter with dual channels, the Machineroom 204d is an excellent choice. Its unique features, such as voltage control, sync functionality, and CV attenuators, make it a valuable addition to a modular synthesizer setup. However, if power consumption and size are major concerns, consider exploring other filter options with lower power requirements and more compact designs.
