The Millenia NSEQ-4 is a Two Channel Class A Discrete Solid State Parametric Equalizer.
A great sounding EQ! I had the NSEQ-2 which I Liked a lot. I used the solid state mode on most of the tracks I mastered, so once I had heard that the NSEQ-4 came out I was very interested in checking it out. When I hooked it up and worked with it ,I fell in love with it. Its clear, its full and it can really sparkle..

Wonderful wonderful low end..
Sweet, transparent, clean - loved the original NSEQ-2, but this was quite an improvement!

The NSEQ-4 has brought new meaning to "elegance" in audio control and sound quality. Where the NSEQ-2 was head and shoulders above many other equalizers in musicality, control, and audio quality, the NSEQ-4 has taken all those attributes to a new level. I ran a 2 vs. 4 test with a solo piano recording: One channel only split to both the 2 and the 4 and returned back to the monitor. I set the same frequency on each EQ and pushed both units to the max at that frequency since I wanted to learn what the worst case scenario might be. With piano, this would usually yield a hopeless result - even the slightest shortcoming will show in most any EQ unit when pushed this way. The NSEQ-4 actually held up quite well to this sort of abuse! Additionally, I found the residual noise level of the NSEQ-4 to be subjectively quite a bit lower than the NSEQ-2. I liked the "character" of the residual noise of the 4 much better. The noise is so low that it is no concern whatsoever in listening or use.
