The Elysia xfilter 500 is a 500-series format analog stereo equalizer manufactured by Elysia, a German pro audio equipment company. The 500-series format is a modular format used in professional audio recording and processing equipment.

The Elysia xfilter 500 is based on the xfilter, which is Elysia’s standalone stereo equalizer. It is designed to fit into a 500-series rack or chassis, which allows audio engineers to customize their signal processing chain by combining various modules in a single rack unit.

The Elysia xfilter 500 offers a range of features and controls typically found in high-quality equalizers. It includes multiple bands of parametric EQ, allowing precise adjustments to specific frequency ranges. Each band usually consists of controls for frequency selection, gain adjustment, and Q (bandwidth) control.

  • Build Quality: The Elysia xfilter 500, like all Elysia products, is meticulously designed, engineered, and handcrafted in Germany, ensuring high build quality and reliability.
  • Class-A Topology: The equalizer employs Class-A discrete signal processing, which is known for its pristine sound and low distortion, representing high-end audio processing.
  • True Stereo Link: Unlike most EQs in the market, the Elysia xfilter 500 processes both its channels with a single set of controls, offering a true stereo-linked EQ. This ensures precise matching of the left and right channels and avoids phase issues.
  • Computer-Selected Potentiometers: Elysia uses custom computer routines to measure every dual and quad-layer potentiometer used in the Elysia xfilter 500. Only the lowest tolerance pots are selected for production, ensuring precise and accurate control over the EQ settings.
  • Low Tolerance Capacitors: The Elysia xfilter 500 uses a special series of film capacitors with twice the component tolerance performance of the industry standard. This contributes to the module’s exceptional sound quality.

Four Active Bands and Passive Massage:

  • The Elysia xfilter 500 offers four flexible active bands: high-shelf, low-shelf, and two mid-peak filters with switchable narrow and wide Q options.
  • The high- and low-shelf bands can be switched to high-cut and low-cut filters with resonance control, allowing for precise frequency filtering.
  • The module also features an additional passive highpass filter with a slight resonance peak at 12kHz, falling off at 17kHz, which adds a touch of HF brilliance to mixes, termed as “Passive Massage.”

True Stereo Operation:

  • In stereo operation, getting precise channel matching can be challenging with regular EQs. However, the Elysia xfilter 500’s computer-selected components and precise stepped controls ensure true stereo operation with minimal channel discrepancies.
  • Computer-selected dual- and quad-layer pots, bench-tested using specialized equipment, guarantee that only the highest-performing pots are used in production.

In summary, the Elysia xfilter 500 is a versatile and high-quality 500-series stereo equalizer module that provides transparent and musical sound. Its true stereo-linked EQ, computer-selected components, and low tolerance capacitors set it apart, making it an excellent choice for adding precision equalization to audio signals in a studio setup.
