dbx 1BX Series Two 3-Band Dynamic Range Expander
The dbx 1BX Series II is a classic single-band dynamic range expander, designed to restore realism to compressed audio (like tapes, vinyl, broadcasts) by making quiet parts quieter and loud parts louder, boosting dynamic range up to 50%. It uses a true RMS detector with an infrasonic filter for accuracy, offers adjustable expansion (up to 1.5:1 ratio), and features an LED meter to show gain change.

  • Dynamic Expansion

    - Increases the difference between the loudest and softest sounds, adding "life" to recordings.

    Single-Band Processing

    - Affects the entire audio spectrum uniformly, unlike multi-band expanders.

    True RMS Detection

    - Ensures accurate processing of signal dynamics.

    Infrasonic Filter

    - Prevents expansion errors from low-frequency rumble or vibration.

    LED Meter

    - Visually shows the amount of gain change (expansion) being applied.

    Adjustable Expansion

    - Ratio controllable up to 1.5:1 for up to 50% more dynamic range.
