BSA Master EQ

BSA Master EQ is a precision stereo equalizer plugin designed for mastering and critical mixing. The program offers clean, transparent sound with discrete controls.

Interface Overview

The interface is divided into two identical channels (CH1 and CH2), each featuring 4 equalization bands.

Parameters & Controls

Each of the 4 bands features the following controls:

• Frequency (FREQ): Selects the center frequency of the band.
  • Band 1: 19Hz - 530Hz.
  • Band 2: 21Hz - 572Hz.
  • Band 3: 617Hz - 24kHz.
  • Band 4: 665Hz - 27kHz.
• Gain (GAIN): Adjusts the boost or cut at the selected frequency.
  • Range: +/- 10dB (approximate) in discrete steps.
  • Default: 0dB (Unity Gain).
• Bandwidth (BW / Q): Controls the shape and width of the frequency band.
  • 0: Shelving.
  • 1: 4 dB/Oct (Very Wide / Musical).
  • 2: 6 dB/Oct (Wide).
  • 3: 9 dB/Oct (Medium).
  • 4: 14 dB/Oct (Narrow).
  • 5: 20 dB/Oct (Surgical / Notch).
• Active (IN Button): Turns the individual band ON (Active) or OFF (Bypassed).
  • Lit: Band is Active.
  • Unlit: Band is Bypassed.

Global Controls

• Link L/R: When enabled (checked), any parameter change made on Channel 1 is automatically mirrored to Channel 2, and vice versa. This ensures perfect stereo synchronization for mastering.
• Output: Master output gain control to compensate for overall level changes.

Visual Aids

A legend table and graph are provided at the bottom of the interface to visualize the curve shapes corresponding to each Bandwidth (Q) setting.
