McDSP Royal Q Equalizer Plug-in

The Royal Q is a dual-channel 4-band equalizer featuring parametric and shelving EQ, mid/side processing, and trim controls. The Royal Q equalization is complimented by a custom analog section for a truly unique hybrid processor. The Royal Q offers independent (or linked) control of the left/right (or mid/side) channels.


    • Double precision equalization calibrated to an all analog output stage
    • Parametric and Shelving equalization modes
    • Dual channel operation and mid/side processing option
    • Sample accurate automation of analog processing
    • Included with APB hardware purchase


  • The APB platform now supports AAX, AU, and VST3 plug-in formats
  • The APB platform now supports Cubase and Logic, as well as Pro Tools


The full featured parametric and shelving EQ modes of the Royal Q are calibrated with a custom analog output stage for unprecedented hybrid processing. Equalization boosts and cuts interact with the analog output to deliver a wide range of responses and a unique sound. Deep lows. Shining highs. You get the idea.

Mid/Side Mojo

Both the Royal Mu and Royal Q offer exceptional mid/side processing using unique hybrid processing techniques. Sample accurate control and self-calibrating analog circuitry insure exacting mid/side encoding and decoding.

Analog Saturation

Like all APB plug-ins, the Royal Q custom saturation circuit is perfectly calibrated with the A/D conversion. When using the Royal Q equalizer, any signal peaks over 0 dB are processed by real analog saturation circuits. These saturation circuits output levels are then matched to the A/D conversion, preventing any digital clipping.


An important aspect of any APB plug-in is that the plug-in is primarily a controller. The APB plug-in takes the input audio signal, combines it with a control signal, and sends both along a Thunderbolt connection to an APB unit for processing. The control signal sets up the analog components to do the selected algorithm with all the parameter values, and the audio signal is converted to the analog domain. The analog version of the audio signal is processed in the analog domain, and then converted back to the digital domain.

By operating the APB hardware from an APB plug-in in this way, all user controllable parameters are recallable and can be saved as presets. Furthermore, because the control signal is married to the input audio signal, parameters can be updating during playback with sample accurate automation.
