This is not only a Graphic Equaliser but a Parametric Equaliser along with a crossover and compressor.
You would be hard pushed to find better at the price.
It may take some time to get your head around all it can do.
it may take some time to keep plugging it in and making adjustments but it is definitely worth while.
I do have one gripe though it should be clear that this device does not come with a power supply so please take this as a heads up.
Installed between my preamp LFE output and subwoofer two channel amplifier and only used as a LFE
Crossover .
The unit is extremely effective in this manner as I was able to fully utiliz the the crossover slopes and parametric EQ to remove peaks in my room .
The bass is now very articulate and with no "boom" whatsoever.
