The ST-LEQ1 Loudness Equalizer (VCA Compatible) from RDL is a device designed to equalize loudness. It features (2) line-level audio inputs and a single line-level audio output. This unit allows you to adjust loudness contour to follow volume, improve aural flatness at low levels, and define loudness equalization.
The audio signal that needs to be equalized connects to the EQ input. If you wish to mix an unprocessed source with the output signal, a second source can be connected to the additional input. Loudness equalization is applied as the control voltage is varied.
This unit may be used in conjunction with any equipment that provides a 0 to 10VDC control. It is specifically designed for use with other RDL VCA remote control modules, which allow this unit to work with automatic loudness equalization.
