GUI features :

  • USB indicator : When communication via USB with amp is successful, the GUI's "LED" indicator will light blue. Otherwise, the "LED" stays dark.
  • Processing Selection : Selecting any icon can effect change in near-real time (NRT) to the amp's audio outputs.
  • Main Control Screen : Control each DSP processing parameters: Threshold Power, Attack Time, Release, along with 5 digital PEQ bands.
  • Sub In/Out Level Monitor : Monitor the input signal and sub output signal levels.
  • Tools Drop Down Menu : Utilities for amp DSP management, plus Wi-Fi settings.

The GUI's graphical trace is NRT editable. Bands can be shaped by cursor or direct input and/or sliders.

5 bands digital PEQ :

  • a) Band ON/OFF : Bypass or enable by clicking the colorized 1 ~ 5 buttons.
  • b) Center Frequency (CF) : Adjust Center Frequency of each EQ band, 20 ~ 200Hz. Steps: 1Hz.
  • c) Gain : Adjust the EQ gain (apparent volume), -12 ~ +6dB. Steps: 1dB.
  • d) Q (Largeur Égaliseur) : Adjust the "Q" value, 0.4 ~ 11. Steps: 0.1Q.

Limiteur :

  • Threshold : Adjust the limiter "threshold power", 0 ~ -12dB. Steps: 0.1dB
  • Attack : Adjust limiter "attack time". This controls the allowed amount of time signals may be over threshold power. Range of adjustment is 0.1 ~ 100ms (milliseconds). Steps: 0.1ms.
  • Release : Adjust limiter's "release time". When limiter is triggered, this control adjusts the time allowed to restore full power. Adjustable range 100 ~ 5000ms. Steps: 0.1ms.

iEQ™ Intelligent equalizer

The integrated 20Hz microphone allows you to estimate the frequency response characteristics of your listening room and thus apply PEQ filters to compensate for anomalies. To perform this measurement, simply connect the 3.5mm jack connector to the Mic In port of the amplifier.

To measure the acoustics of your room, it will be necessary to move the microphone around your room, especially at the listening point. It is preferable to attach the microphone, for example, with a camera tripod for best results. Only three test points are required, the microphone captures 12 measurements for each location and performs averages.

Starting iEQ : Selecting the GUI's button starts custom calibration test tones. After moving your mic to three different listening locations and estimations are finished, the system screen will display the final measured and calculated post-equalized frequency response results.
