Sound Workshop Reverbs of the 1980s

Download the four-page catalog for the Sound Workshop 242C and 262 stereo reverberation devices:

DOWNLOAD: SoundworkshopReverbs

I’ve been using a 242C in the studio for years; it’s ok for signals that don’t need much high or low end.  It’s pretty boing-y and a little bit noisy.  It does have a cool dense, gritty texture that give backing vocals a nice old-school character.  At this point, i have learned to always use it in the following way:  usually I pre-delay the input 10 or 20 ms; then run the input signal through a gentle compressor (usually DBX 160); and cut the highs and lows on the return to remove hiss and hum that the spring pickups introduce.  Oh yeah and the 242C is not really intended for +4 studio use; so i also use a Peavey stereo +4/-10 converter in order to best gain-stage it.   So yeah… a lot of support equipment around this humble box.   It does get a lot of use tho.  Hey at least it has overload LEDs and and a very-useful ‘input mix’ switch with combines both inputs – great for creating pseudo-stereo from a mono source.

Effectron Digital Delays Original Catalog

Download the four-page catalog for the Delta Lab Effectron line of the early 1980s:

DOWNLOAD:EffectronCatalog

If you have been following this site for a while, you will know that I dig the Effectron.  There are a  world of creative possibilities in these well-made, cheap-to-buy boxes.  Examples turn up regularly for $50 – $100.   10 minutes with one of these things will teach you more about the range of effects available using a modulated delay than you will get from a year using the plug ins.  True, there is nothing that these boxes can do that Digidesign MediumDelay can’t; but the immediate tactile response of the knobs can’t be beat.  Highly recommended.

Orban Audio Processors of the 1980s

Download the four-page circa 1984 Orban ‘condensed catalog’:

DOWNLOAD: OrbanCondCatalog

Photos and descriptions (no specs) of the following models: Orban 111B reverberation; 245F stereo synthesizer; 418A stereo compressor/limiter; 424A Gated compressor/limiter/De-Esser (i.e.,  ‘make-it-as-loud-as-the-FCC-will-allow’ box); 516EC 3-channel De-Esser; 526A De-esser; 622B 2-channel parametric equalizer; 672A equalizer; 674A stereo equalizer.

I have been using a 111B reverb for many years in the studio to augment the usual reverb plug-ins.  It is the best spring reverb unit I have come across.  I have found that it absolutely needs a little pre-delay applied, or else weird phase cancellation occurs when I sum the reverb output back into the board along with the direct signal.  There are may easy ways to do this, but it is worth noting.

Orban was founded three decades ago by Bob Orban.  They have always made audio equipment aimed at the radio broadcast market.  Prices for their classic 80’s gear were reasonable until recently.  Plenty of these out there, tho, so if yr patient and you will get a deal.

Since Orban is in the business of supplying broadcasters, their website have excellent technical support.  You can download the original manuals for all their products at this link on their site.

Valley People Modular Outboard Gear Circa 1984

Download 5-pages of original Valley People literature regarding their ‘Series 800’ modular racks, plus 3 period pricelists:

DOWNLOAD:ValleyPeopleSeries800_and_pricelists

Our pal T.W. rang this week inquiring about this product line.  Figured that made this as good a time as any to upload all of the old Valley People literature in the collection.  Later this week: original product-sheets and manuals for the Dynamite, Model 610, Kepex II, and Gain Brain II.

Interesting to note that V.P. is promoting ‘transformerless mic preamp’ replacement for MCI consoles.  Nowadays, the only reason that most folks would chose to purchase an old MCI console is because of the transformer-mic-inputs.   And everything old is new again…

Tubes vs. Transistors in Recording Equipment

“Engineers and musicians have long debated the question of tube sound versus transistor sound.”

From the AES Journal, in the form of a paper first presented in 1972, Russell Hamm delivers a quasi-scientific study and analysis of the difference between tube and solid-state microphone pre-amps.  Click here to read the fourteen-page article. This paper confirms what most recording engineers seem to realize intuitively: solid-state and vacuum tube amplifiers operate equally ‘well’ (read: musically-pleasing) when operated totally clean.  However, Hamm reports that tube microphone pre-amps offer 15 – 20 db more acceptable semi-distorted headroom on transients, while only showing a 2-4 db actual increase in electrical output over this range.  I.E., as Hamm states, tube microphone pre-amps can be extremely effective compressors.  There’s more to it than that; read the piece and draw your own conclusions.

Fostex ‘Personal’ Outboard Equipment of the 1980s

Download fourteen-pages of original product information regarding FOSTEX’ “Personal Multitrack” outboard-equipment line of the 1980s:

DOWNLOAD: Fostex_Outboard_Gear_1986

Included in this download:  “Echo Buss Vol II, Take 1,” a FOSTEX newsletter to pro-sumer users of the 80s.  Plus 2-side product sheets for the 2050 line mixer, 3030 Graphic Equalizer, 3070 Compressor/Limiter, 3180 Reverb, and 6301 powered monitor speakers.

The 3180 offers a unique feature among line-level stereo spring reverb units:  a non-adjustable 24ms pre-delay hardwired before the spring drive amp.

Interesting to note that FOSTEX makes no attempt to disguise these pieces as pro-studio equipment; they were designed and marketed specifically for use in the new ‘personal studio’ of the early 1980s, alongside such other FOSTEX offerings as the personal reel-to-reel multitrack and the FOSTEX 250 cassette four-track.  See previous posts here, here and here for information on these recording devices.

The Fostex 6301 powered monitors did enjoy wider use, though; true to the photo at top, these compact 10w powered speakers did in fact experience wide use in video-facility machine rooms as basic program monitors.  Many are still in use in this role.

Magnecord INC Historical Archival Material Part 1

From the personal collection of D. Boyers, son of Magnecord founding partner John Boyers, PreservationSound is excited to be able to offer several rare documents and historical reminiscences.  The Magnecord PT6 was one of the very first broadcast-quality tape recorders ever made – 1948 – and you can still find working (or repairable) examples.  If you have been following this site for a while, you will know how much I like these machines.  See this link and this link for some examples of recordings I have done recently with the PT6.

John Boyers was one of the founders of Magnecord.  He is now 95 years of age.   His son D. provides these notes regarding John’s career and contributions to recording history:

“I wouldn’t be too surprised to learn there are some (PT-6s) still in use, probably in some third-world broadcasting station somewhere. My first PT-6 was an engineering sample put together prior to the start of manufacturing. I still have it, and it still works, (although I make that claim having not tried to fire it up for 30 years!)
Dad is still with us, although he is the last survivor of the original group, at age 95… One of Dad’s favorite stories… is the time he couldn’t make payroll, but the man at the bank gave him the funds he  needed because of the trusting relationship he had built with the bank.

 

Dad’s interest was mostly engineering. He designed the heads, experimenting with various metals and ways to make the recording gap smaller and smaller. Back then, the
heads were built one at a time, by hand. One of the handiest features of the “6” was the
ability to do instant playback head alignment with that little 4/40 screw and spring
tensioner. …I don’t remember if that was a feature of the production machines or if it was just something  they built into the sample I have. Oh, here’s another story you might enjoy knowing about: Dad and one of the other guys in the shop had a brainstorm and decided to build a “binaural” (ed: Stereo) transport just for fun. They  got it working and took it down to the Illinois Central train station and made a recording of a steam locomotive going by.
I remember hearing the recording, with the locomotive coming in one channel and going out the other. The binaural recorder was the hit of the audio trade show in Chicago that year. According to Dad, the crowds around the little Magnecord booth were huge and the buzz of the show was all about the unbelievable train recording. I asked Dad why they didn’t get a patent on it and he says that it wasn’t patentable. It had been  done before, although not commercially, and it didn’t meet the “new and novel” requirement of patent law. I’ve often wondered if they weren’t just working with the wrong patent attorney.”

Thanks to D. for sharing this history.  We will leave you today with the remainder of a set of Magnecord-Factory photos circa 1950.

The Fostex 250 and 250AV cassette four-track machine

Fostex week continues at PS dot com. Download five pages of original FOSTEX product information on the 250 and 250AV ‘four-tracks’:

DOWNLOAD: Fostex250

I’ve never used one of these machines personally.  Anyone?

The 250AV, btw, is the same as the 250, except that it runs at 1.875ips (the same as a regular consumer tape deck); the intent was to simplify multi-track bouncing in audio-visual post-production situations.  Read the product sheet and you will see what i mean.  It also boasts a 5db lower crosstalk spec than the 250;  FOSTEX claims that this allows a pulse (sync) tone can be placed on one the tracks to drive other machines without the pulse -sound  getting into your other 3 tracks.

The Fostex A-8 multitrack tape machine

Download the original 2-page product sheet for the Fostex A-8LR tape machine.

DOWNLOAD: FostexA8LR

Billed as being “about the size of twenty albums stacked together,” the A-8LR differed from the more common A-8 by virtue of 8-track simultaneous recording (as opposed to 4-track simultaneous on the A-8).  We had one of these machines in the house briefly when we were kids and it did not sound very good.  The A-8 records on 1/4″ reel tape.  It is certainly very small for an 8-track machine.
