Clean and huge sounding. Amazing value for money.

The hi end boost is gorgeous, the air does exactly what it says, giving a smooth top end boost without getting harsh. The lo end is huge! This is what I was hoping for, some clean, fat lo end, which is rare of eqs of this price IMO. - Click to read full review of PEQ-503.  - hiddentrackstudios.co.uk, UK

I installed them the other day and had a quick listen. (PEQ-503)

First thing I did was put all the bands on full boost and listened. No noise! Always a good start.

As I said, I havent spent loads of time with them, but here are my first impressions;

The hi end boost is gorgeous, the air does exactly what it says, giving a smooth top end boost without getting harsh. The 12k setting gives much more detail while still sounding smooth.

I changed the mid band to 1k up, 320hz down and it really fits my needs. The 1k is quiet narrow q; perfect for cutting out a bit of boxiness when tracking a kit. The 320hz is much broader, great for cutting some mud from a mix or adding some depth to an instrument.

The lo end is huge! This is what I was hoping for, some clean, fat lo end, which is rare of eqs of this price IMO. The 2 frequencies sound quite close together, even tho it should be 120, 35. I may experiment with these, but the boost/ cut is very broad and can be as subtle or extreme as you dare!

As I said in a previous post, the build quality and finish is great.

The only thing I wish it had was detonated gain pots for stereo matching and recall. It's pretty hard to match 2 units as the knob pointer doesn't run down the side so you have to kind of squint to see it right. Certainly no deal breaker tho.

Overall, these eqs are exactly what I had hoped for, and are clean and huge sounding. Amazing value for money, one happy customer
