Default PPi E.7... Great budget EQ.

Really quickly...

I've been looking for a decent budget EQ and ran across this one in my search so I decided to give it a shot. I wasn't expecting much from an $80 EQ (Amazon), but I was pleasantly surprised.

First (and I knew this already)... it's parametric (well... "para-graphic"). What's that mean? That means you can dial in exactly what frequency you want to cut/boost instead of having to choose from the fixed bands that others give you. With only 7 or 9 bands, chances are pretty good that a trouble spot will land between the fixed bands. I call it "para-graphic" because you can adjust the frequency, but there is no adjustable 'Q' like you would find on a true parametric. But... still better than a graphic.

2nd... when you use the little screwdriver that's included to adjust the frequency... it has a digital display that tells you what frequency you're on! No more guessing or eyeballing it. This is an awesome feature. Awesome.

Speaking of the digital display... as a default (when you're not fiddling), it is a DC voltage display. Bonus.

The unit has an adjustable bandpass crossover for the sub too. The SSF is on the top, but the LPF is on the faceplate and you can also dial this one in with the digital display.

Sub level control is handy. And considering a PAC knob and a Stinger voltmeter would run you ~ $40, you're really saving money.

The unit only has RCA inputs. High level inputs would have been nice. It's only 2 channel in, but 6 channel out- front, rear and sub. It also has an aux input that's selectable from the face.

The backlighting is bright as shit at night. Bright enough to blind you from actually seeing what knob you're trying to turn.

Subjectively.. it's quiet. I was expecting it to be noisy, but I listened for a while with everything "flat" and it was transparent and didn't add any unwanted noise. The frequency centers seem to be right on the money according to my RTA. I can't confirm what the 'Q' is.

Overall... if you're in the market for analog EQ... I can recommend this unit and feel like it's a much better buy than the Clarion that's so popular.

Seen here adjusting the "mid-high" band and have it adjusted to 2.7khz as evidenced by the display. It automatically switches to this and back and forth between Hz and Khz.

Hey, the PPI site says 7V Max, everybody loves a Max rating [ also says WHITE backlight controls ]...right?

Honestly, it looks like a decent $80. I do have a question though, if you change the Sub LPF does the HPF for the F/R change too or are the through/set?

I didn't. But they're higher than what they were because I didn't change my gain positions and it's louder now.

Super scientific, I know. Lol.

As far as I know... it doesn't have any crossovers other than the sub.

No. LPF only goes to 120hz, I believe.

Guess that is where they saved money, by leaving the HP filter off.

MiniDSP or BP capable amp?
Wait don't you have that active capable Pioneer deck installed? Can't that do it or are all the channels filled already?
