Link Audio Design
This is a Program Equalizer in 500 API Format, it's based on a classic styled 4000 Black (E242) Equalizer. Rare and possibly the most difficult EQ to pin down as views on this one are very polarised. Compared to Brown EQ - Black EQ is louder +/-18dB, Gain changes with Q-Settings.
Very Flexible and very precise calibration for all needs. We added to this 4 Band Equalizer a Low and High Cut Filter to make it more flexible in Mixing or Recording situations.
Improved Build - Easy Final Assembly and Testpoints
