The EQUALUX is a discrete parametric equalizer with some features that might surprise you, or that you might not even see at first glance. Notice that the panel has no Q control. What? A parametric EQ with no Q control? What strange land is this? The filter Q control functions according to an algorithm in relation to the Boost and Cut control, and uses a "Constant Energy Curve" (also known as "Proportional Q") that keeps the bandwidth wider at lower boost or cut levels and becomes narrow at higher boost or cut levels.
We know, we know, you're an excellent engineer and you don't need anybody bossing you around and telling you what your Q should be, but the fine folks at Tonelux didn't just flip a coin and pull the Q from the design. Much coffee and many pizzas were harmed at Tonelux headquarters over the course of arriving at this decision, but the staff engineers agreed that Proportional Q is best so often and sometimes such a nuisance to dial in that strapping the Q to the cut and boost controls would be a perfect solution for a lot of studios. The Equalux was born.
With four bands of controls, each of the lower two have slightly different frequencies, allowing the lower band to go to 18 Hz, and the upper two 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.
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.
