Equalizer with Spectrum analyzer. Silly, but I want one.

Being a Yamaha fan I really want an EQ-630 or EQ-1100 or something. Admittedly because I enjoy hunting components.

Seems like these are toys from yesteryear and the modern opinion is that they are not serious gear that only add noise. Or, can a decent one have any sonic benefit?

Not toys!

I'm looking also. Need to get one with RTA and a mic to properly EQ for room. Maybe an GE60.

My EQ-3000's made me realize the benefits outweigh any drawbacks, or supposed drawbacks.

Room equalizers!
 
Maybe consider something like freeware Room Equalizer Wizard
https://www.roomeqwizard.com/

Originally designed for room EQ, there were some useful add-ons like RIAA/frequency response
and distortion measurement which interest me until I can afford the $$$'s to buy a test unit.

I wouldn't use a graphic EQ fearing the loss of hi-fi, prefer to focus on mods to room layout
using tools like REW. Still learning the SW, takes a little time...

Not silly at all. I'm going to get one to hook up to the tape out on my receiver. Just so I can watch the Lights. Love some spectrum analyzer lights for show.
 
Yamaha GE-60. Nice little spec analyzer that visually shows you differences between your phono cartridge spectrum.
The EQ is nice but lets face it, most of us rarely use the actual EQ part.
Plug into a tape loop and you get 2 tape loops out of the back of the Yamaha.

Looks like the EQ-550 is an updated version of the GE-60?
 
Had an EQ-550 and liked it a lot, until it broke. It's a cosmetic update of the EQ-500. In fact the differences are so slight that I simply bought an EQ-500 and swapped the faceplate and buttons from my 550 onto it because I preferred the updated look.

The GE-60 is a bit of a different animal, its sliders are grouped in sets of two (left and right channel) for each frequency. On the 500/550 and similar the sliders are simply grouped by channel.

I prefer the functionality of the GE-60 but that's just me
 
ADC has an EQ model with stereo 12 channels and a display for audio analyzer. I have one somewhere but I never wanted to spill the bread for the calibrated mic.
 
Love my Technics with the Parametric EQ. Not a true RTA but it does give you a great deal more control than the ubiquituos Bass/Trebel controls of this period. Plus, it's cool visually which never hurts :)

If you're mostly into the display, I'm a fan of the old BSR 4000xr. That florescent display really shines ...


Oh - and anyone looking to buy a unit with RTA, make sure it comes with a test mike. And make sure it's the right mike - Most of those EQs are calibrated to use a specific one and your results will be useless if you get the wrong one.

PS - fun part of the video - the left=right indicator tells me this one was just used as eye candy as it's not doing any real EQ ...;-}

I have tested My EQ 3000's with a few different mics, like yamaha, pioneer, denon, adc, etc.

Most electret mics don't vary much, but... a caveat...

I tested my Nippon built 3000 vs. the china built,....the china built would work with all mics, but the Japan built unit would only work with the actual ADC/BSR mic...go figure. IIRC!

A friend of mine just gave me a Yamaha EQ-630 yesterday because he sold his house and is moving to Florida.
He also gave me a nice Teac R-919X cassette deck that doesn't work. Both have remotes. The Yamaha remote is still in the bag. I haven't had a chance to play with it yet, but it did turn on when I powered it up.

The modern AK consensus seems to be that each element in the array of bandpass filters introduces independent phase shifting at each passband. This tends to smear the perceived location of sources on the "soundstage", due to the spectral "breaking up" of the original phase profile. The result of this "breaking up", or spreading, of the original phase profile is that the original sources now seem to emanate from several shifted new locations - shifted according to the phase errors introduced independently by each equalizer band. A solo singer breaks up spectrally / spatially into a weird choir. This is just my humble compilation of technically vague speculation and testimony gathered from other equalizer threads. As far as "noise" is concerned - IFAIK everything at a temperature above absolute zero introduces noise.
 
Neat thread.

I have a pair of EQ-550 that I picked up new, used for about two months, and then put back in the original boxes and original packing material. Pretty sure the mics are still unopened, in the original bags. I wonder if they still work. It was a passing idea to EQ a home theater system, back in the early 90s when Pro Logic was a thing. I had no idea they might still have a small amount of value. They weren't terribly expensive when new.

Back in the day, I had a Kenwood KA-7300 integrated (still have it) and a pair of Polk RTA-12B speakers. I thought the Polks would be an upgrade from some low end PSB 50 MkII speakers. They were but not much.

Anyway, on that system I never noticed a negative effect of having the EQ inline. I could switch it in and out with no change in output, when they were set flat. Keep in mind how modest the system was. It was what I could afford, at the time.

The EQs never did find their way into my theater system, back in the day. I used to have a ton of components, including pair of S-VHS editing decks. There was never any space in the pair of equipment racks I ran.
