Thought I'd reach out and see if there happens to be any lurkers here who have an in-depth knowledge of EQ's. I've reached out on several other forums and gotten zero help.
...I've been eyeballing some hardware units to try and get a super immaculate sounding hardware unit that can be used in cinematic VO. I saw a REQ2 go up for grabs on eBay, but I don't enough about them to understand what some of this means. I'm no dummy when it comes to EQ units, but this stuff may as well have been written in ancient Hebrew. Was wondering if someone can dumb this down so an idiot like me can understand it:
The REQ-2.2 equalizer utilises parallel resonant circuits in a clever configuration whereby the bandwidth (Q) of the circuit can be adjusted like an active filter, but without any complex relay switching. The inductor/capacitor resonant "tank" eq circuit runs at a low internal signal level which avoids any inductor saturation effects. The overall result is the sound of real choke based filters with a big open sound, but without the limitation of only a few - or no bandwidth selections as found on traditional choke eq's.
What is the relationship between the active filter and a relay switch?
Whats a tank circuit?
And whats a choke based filter?
we have included a saturation section that introduces measured amounts of low frequency harmonic distortion via a steel audio transformer driven by a single ended tansistor amplifier. The High Pass Filter is placed in the beginning of the eq chain and the Low Band eq section is placed last in the chain. This layout produces the best overall equalizer coherency.
What the hell is a single ended transistor amplifier? If a transistor amp isn't single ended...well...what else can it be?? I'm really fucking confused.
Ugh??? How you have HPF -> Low band EQ and also claim the unit is parallel? WTF? Doesn't that make it NOT parallel by definition?
Help. Please.
