Speaker Week(s) Begins with Jordan Watts

Jordan_Watts_GT_Jodrell_JupiterHow y’all doing.  Sitting here on the (what feels like) first day of fall, listening to a pile of weirdo 70’s UK punk LPs: The 999, Steve Harley, The Stranglers, and The Doctors Of Madness.  What better match than some musty old paper describing some oddball British speakers of the era: Jordan Watts.  This is the first of what will be many uploads of late-70s speaker ephemera, both HiFi and pro-audio.  I have 100s of pieces of this stuff to go thru, and finally a free minute to do it.  So get ready… and remember to check if Orange County Speakers has re-edge kits available for any foam-edged 35 year-old-speaker yr thinking of buying.   Anyhow, download a complete late-1970s JORDAN WATTS hi-fi speaker catalog:

On offer: the Jordan Watts models Juno, Juliet, Jumbo, GT, Jodrell, Jupiter, TLS, Jericho, Centurion, Qubique, and Flagon.Jordan_Watts_juno_juliet_Jumbo_JanetThe Jordan-Watts speakers used a very unusual 4″ metal-coned driver unit that came in its own integral mini-enclosure.  Even stranger tho are their Arabesque and Romanesque “Qubiqe” and “Flagon” models:

The Studer 169 Portable Audio Mixer c. 1980

Studer_169_mixer_1Got a pretty good one for y’all today… download the complete 12pp catalog for the Studer 169 Portable Audio Mixer:

DOWNLOAD:Studer_169

Oh Studer 169.  How long you have taunted me on eBay.  How little use I would probably find for you.   Available in configurations varying from 8 to 11 inputs, 1 to 4 masters (each with integral limiter), the 169 was a 19″ rackmoutable mixer.   Anyone using of these?  Weigh in!

New Video : “Build A Variable H-Pad”

FirefoxScreenSnapz002How are y’all doing today…  we have a new video ready: “Build A Variable H-Pad.”  If you’ve ever wanted an easy, controllable way of reducing level in the studio without losing signal balance or creating wild impedance variations (which can have undesirable consequences frequency-wise), this project is for you.  I have a couple of these little boxes at Gold Coast Recorders and they get used pretty often; the most common use would be if I want to crank up a tube mic preamp to get some break-up on a drum kit or vocal mic.  If this results in an excessive output level, I can just patch in one of these variable pads and dial in a safe level for the A/D convertors.

Check out the video, and here’s the schematic for anyone who wants to build one of these lil fellas.  You’ll need two balanced jacks of your choosing, four 1% 1-watt 160-ohm resistors, one 200-ohm 1-watt resistor,  a 1-watt 1-K linear taper pot, a terminal strip, and a small enclosure.

The EMT 250 and 244 Digital Reverbs

EMT_250Download the original product-sheets for the EMT 250 Digital Reverb and its baby bro the 244:

DOWNLOAD: EMT_244_250_reverb

That giant 99-lb star-wars-lookin thing above is an EMT 250.  Ten years ago I was working on a session at Ocean Way Nashville and they still had one of these things right next to the console.  Anyone out there still using a 250 in the studio?  The 250 uses 12-bit, 24k convertors, which means that both input and output are low-passed at 11Khz.

EMT_250_flowThis brings up a good point about reverb in general: you don’t need a lot of hi-end to create good-sounding reverb for most applications…  I always keep some sort of low-pass filter active in my reverb returns to trim off anything that’s not contributing in a meaningful way.  Luckily, even the most basic reverb plug-ins tend to have a low-pass adjustment built in.  My $0.02: use it!

250_reverb_diaVery interesting to read this: so apparently the 250 uses 19 different taps, with feedback only on some of them.

EMT_244The lesser-known 244 (i’ve personally never seen one, FWIW) uses 13 bit convertors; no sampling rate is specified, but given that the frequency response is stated between 30hz and 8khz, it’s likely around 20k.

To you veteran engineers out there: was the 250 the first high-quality digital reverb? Were there any earlier units that you have used?  Let us know,,,

The Sound Of 23.5 Karat Gold

EMT_240Download not one but two circa ’72 brochures for the EMT 240 ‘Gold Foil’ reverb system:

DOWNLOAD: EMT_240_reverb

The 240 was apparently intended not to replace the 140 so much as provide a smaller, portable (132 lbs haha) alternative.  I’ve provided y’all with 10 pages of documentation here, it’s worth reading..  this thing really is an engineering marvel.  Rather than a ‘plate,’  the reverberant surface is a tensioned sheet of gold-foil 18 microns thick.  This gold-foil material, btw, was a completely in-house-made material…  fkkn crazy.  Anyhow, check it out…   those of you who have had experience working with both a 140 and 240, pls weigh in on the relative merits thereof.
