Is this the complete list of 500 series EQ's?

[Kronos147]

I added to a 500 series thread on another site but I thought this should be asked here too.

Is this the complete list of 500 series EQ's?

A Designs EMPEQ - 2 band pultec design

Alta Moda Audio AM-20 - 4 band, 2 band fully parametric

API 550A - 3 band + high/low pass filters, Discrete, High and low bell/shelf switches
550b - 4 band, Discrete ('hybrid'), High and low bell/shelf switches
554 - 3 band sweepable frequencies
560 - 10 band graphic, Discrete (vintage) and hybrid (new) models

Anamod AM EQP - "500 series incarnation of the classic EPQ1A" 2 band + filter

Arsenal Audio V14 - four band fixed bandwidth

Avedis E27 - 3 band + high/low pass filters, Discrete, High and low bell/shelf switches

Buzz Audio Tonic - 3 band, mid with 10? x2 selectable frequencies + HPF, Class A, "utilizing both real chokes and electronic filters"

Daking Plus EQ500 - no longer in production :-(

Eisen LiLPEQr - no longer in production :-(

JLM Audio PEQ500 - "Pultec EQP-1A & EQP-1R type passive EQ circuit w/ 8 extra low and 5 high frequencies...the Q control will switch the high boost to a shelf...

Purple Audio Odd Inductor EQ - 4 band with two selectable frequencies per band, High and low bell/shelf switches.
Tav 10 band graphic - inductor based graphic EQ

S&M Audio EQSM1 - 4 band w/ HPF, high and low shelf with 2 selctable frequencies and two mid bands of semi-parametric fixed bandwidth EQ, true bypass feature

Speck ASC-V 4 Band Parametric EQ
Low band - semi parametric 25Hz - 400Hz, peak/shelf switch
Low/mid band - fully parametric, sweepable, switched between 40Hz - 800Hz or 400Hz - 8kHz, variable bandwidth
Mid band - fully parametric 400Hz to 10kHz, variable bandwidth
High band - semi parametric 2kHz - 25kHz, peak/shelf switch

Having only heard a few of these, I ask for opinions of the following assessment:

Color:
EMPEQ
550A
550B
560
AM EQP
V14
PEQ500
Tav

Surgical:
AM-20
ASC-V

Crossover (a little bit of both):
Tonic
Odd
EQSM

For those who have experienced most if not all of these units, in what order would you suggest someone audition units for color, surgical, or crossover use?

Also, what do you find is more useful to you in an EQ, color or control?

Hi Kronos...

thanks for asking! now what other site might that be? ;)



Is this the complete list of 500 series EQ's?


A quick cut-paste of the latest version of the database (http://lunchboxhero.com/500seriesdb.html) and clicking on the "type" header (to sort / reveal all eq's together) shows:

API API 550A
API API 550B
API API 560

A-Designs EM-PEQ

ALTA MODA AM-20

AnaMod AMEQP

Arsenal Audio V 14

Avedis E27

Buzz Audio Tonic

Daking Plus EQ500

Eisen LIL PEQr

Electrodyne

JLM Audio PEQ500

LAZ Pro Audio EQA

Purple Odd

Purple Tav

S&M EQSM1

Speck ASC-V

So I appear to be missing the API 554... otherwise it's a match for your list. phew! But if any one replies that I am missing something, please let me know so we can update the db.



Eisen LiLPEQr - no longer in production :-(


I understand from Eisen's site (http://www.eisenaudio.com/) that they are planning another run of the Lil PEQr. :D

I tend to lean towards color and I would say the Lil PEQr and the original API 550 (also not yet listed in the db) are among my faves but...



Also, what do you find is more useful to you in an EQ, color or control?

I do a lot of tracking, not too much mastering, but I sure would like a Speck ASC-V, the A Designs EM-PEQ, or the Avedis E27 for more detail oriented work (the latter two being color with control, imho). That being said I would just like them anyway! and I am rather looking forward to hearing the SM EQ at some point! and the....

Cheers!

Is it just me, or does this thread forget the original (and still 'champion') EQ module, the API 550 (no "A" or "a-1" "B" or any other unnecessary letters...)? I was lucky enough to fill my first rack with 550 EQ units and Averill 312 preamps that were made from 312 cards salvaged from an old console that I purchased and later had supplied to BA. I'm always surprised to learn that many 500 fans know little or nothing of the 550 (no letter) EQ or the 312 cards (no module). Old age is power! (or at least knowledge...)

the API 550 (no "A" or "a-1" "B" or any other unnecessary letters...)?

mentioned it above and i agree, my fave and dearly missed after I sadly sold it in leaner times :(

two op-amps... awesome sound... my intro to API was a pair of original (no letter) 550's.

i hate leaner times :(

i hate leaner times :(

me too! and they had been "gone through" by Avedis... double :(

that is even worse!
insult to injury, dude that sucks big time!:eek:
i am wanting to get some of the 312 BA soon i hope.

The supply of old 312 cards ain't what it used to be. But I don't think anyone will ever complain about the new version made with the Avedis amp. But if you ever come across a pair of old 312 cards, BA will turn them into 500 series modules for a very reasonable price.

i am great friends with Avedis: )~
i would just have him put them together for me: )~
if i ever snag any?

I'm not sure if this is what's currently in production or all that have ever been.

Let's not forget the mangy APSI 559 graphic. I am lucky enough to have a pair, gone thru by Avedis. :D

Also, Inward Connections has their new EQP2 which although only 2 bands looks to be pretty schweet.

Later, Jeff

Avedis just hooked me up with a cool Vintage Aphex lunchbox: )~ been wanting one for some time, thank you AVEDIS!!!!!!!
:D

I want to get these legacy modules in the database, so when I can get to it I will need some help sleuthing!

The eQp2 (http://www.inwardconnections.com/eqp2.htm) deos look to be very sweet indeed. I have yet to hear any IW gear, but have heard nothing but the highest praise for their work. someday :)
