Parametric EQ Section

The four-band stereo parametric EQ section provides flexible analog EQ processing with variable Q control and selectable bell/shelf operation on the outer bands.

Each band offers:

• ±15 dB boost/cut range
• Variable Q: 0.2 – 7

Frequency ranges:

• EQ1: 22 Hz – 470 Hz (bell/shelf)
• EQ2: 90 Hz – 2 kHz (bell)
• EQ3: 480 Hz – 10 kHz (bell)
• EQ4: 1 kHz – 23 kHz (bell/shelf)

This flexible architecture supports detailed stereo enhancement, analog tone shaping, harmonic enhancement, and precision mastering chain control across a wide range of audio mastering and mix bus processing applications.

Passive Equalization and Advanced Filter Control

In addition to its parametric section, the Mastering Equalizer incorporates a stereo passive equalizer with extended high-frequency enhancement capabilities.

The passive section includes:

• Extended air bands at 20 kHz and 28 kHz
