The Tonelux Equalux is a discrete parametric equalizer with some very unique features. Notice that the panel has no Q control. The filter Q control is in relation to the Boost and Cut control, and uses a "Constant Energy Curve" or known as "Proportional Q" that keeps the bandwidth wider at lower boost or cut levels and becomes narrow at higher boost or cut levels. This is musically pleasing.
The curve is identical to many classic equalizers and is one of the reasons they are preferred over newer designs. When the PEAK button pressed, the 4 yellow "peak" buttons keep the width at a constant 1/3 octave for more precision control.
The High Frequency has a Shelving button as well as a Peak button, a new feature for the Equalux. By popular request, we have also added a Low Frequency Shelving switch, so the Equalux can now control HIGH and LOW shelving as well as Peaking for all four bands.
With 4 bands of controls, each of the lower 2 have slightly different frequencies, allowing the lower band to go to 18 Hz, and the upper 2 bands are identical. The IN button is a silent IN/OUT button that does not bypass the unit, but it bypasses the filters. It also has the same feature as the MX and FX series modules, when in, the button pulsates showing signal presence. Internally, this can be selected to read the signal at the EQ input, or post EQ at the output.
In addition to the silent IN/OUT switch, there is also a BYPASS switch that will hard wire bypass the Equalux when pressed in or will also bypass the unit in the unlikely event of a power failure.
On the rear panel there is an "INPUT" XLR with a nominal level of +4 dBu and a 1/4" jack that has a -6dB pad for a nominal input level of +10 dBu. The "OUTPUT" is an XLR with a nominal level of +4 dBu.
