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…

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.

Lexicon Digital Audio Processors of the 1980s

Download twenty-one pages of original Lexicon catalogs and sales materials from the mid 1980s.

DOWNLOAD: LexiconProcessors1980s

Full details, photos, and specs on: Lexicon Model 97 Super Prime Time programmable digital delay; Prime Time II; PCM-42 delay unit; PCM-70 effects processor; 224-X Digital Reverb; plus a period price list and sales letter.

It’s hard to remember just how important these devices were back in the 80s and early 90s, before the advent of DAWs (e.g. Pro Tools) and the audio-processing plug-in effects that accompanied the DAW.  Sure, Lexicon digital reverb may not ‘really’ sound like the sound of a ‘real space,’ but it sure did sound like the sound of a Hit Record for a good long while.  And if you wanted That Sound, the only way to get it was with one of these devices.   There is still some demand for these devices (PCM-42s still go for around $1000 used), likely due to older engineers’ familiarity with these devices, as well as their still-relevant live sound and instrument-rig applications.  Interesting to read these specs and see that, at best, these were 16k bandwidth devices.   Who would dream of setting up a new Pro Tools session at 32K sampling rate these days?

Unfortunately I could not find any paper work on the most expensive item on the pricelist – the Lexicon 1200CMS stereo Digital Time Compressor/Expander.

(web source)

This was a truly significant, cultish device.  You can occasionally find them on eBay for around $200.    Cost new in 1985?  $15,995 for a stereo unit.  In today’s money, that’s  thirty-two thousand ($32,000) d0llars for a device that could (at 32k) pitch-shift a stereo program a semitone or so.

Who in their right mind would pay this money for this kind of functionality?  Broadcasters, primarily.  If you spend any time working in television post-production, you will still hear older producers and creative directors say “Lexicon it” to the sound engineer.  Now, when they say this, they are not telling the mixer to put a shit load of echo or reverb on the audio.  In the post-production audio world, “Lexicon-it” was an imperative to time-shift material.  As-in, “Hey, johnny read that tag line a little slow.  Can you Lexicon it, Joe?”  The vogue for these devices in Broadcast really took off when put-upon ad-agency types realized that you now could make a 32-second commercial, and then speed the spot up to play back in 30 seconds time whilst ‘Lexicon-ing’ the audio program back to regular pitch.  At the end of the day, the TV viewer can’t tell that anything is off, but you, Mr Crafty Agency dude, have managed to cram thirty-two seconds of your boss’s and clients’ revisions into a a thirty second commercial.  You are now a genius.  This is the stuff on which vacation homes are made.

Of course, music-recording engineers also used these things daily to fix pitch-y vocals and what not, but that’s a story for a different day…

Aphex Aural Exciter Lineup circa 1984

*************

*********

*****

Download 6 pages of Aphex Systems INC sales material circa 1984.  Details on the entire lineup, plus full specs on the Type B and Type C ‘Aural Exciters.’

DOWNLOAD: Aphex_exciter

Products covered, with specs and photos, include: Aphex II-S Exciter; Aphex II-B exciter; Type B and Type C exciter; Compellor Compressor; EQF-2 and CX-1 lunchbox cards; Aphex R-1 10-space rack and PS-1 power supply; 4B-1 self-powered 4-slot lunchbox; Aphex 2521 op amp, 1537A VCA IC and VCA cards  500A and 505.

Aural Exciters are essentially dynamic equalizers; as-in; rather than deriving their frequency-manipulation parameters from a set of fixed (or user-variable) static controls, the frequency-manipulation is, in one way or another, dependent on the program material. Furthermore, in the case of the Aphex exciters, the ‘equalization’ is accomplished not by the selective cutting and boosting of certain frequencies, but by essentially creating a distorted duplicate of some of the lower frequencies of the program material and then mixing this distorted signal back into the program with some amount of slight time adjustment; and all of this action is further dependent on the program level.

Aphex was the company that popularized these devices; in fact, many major-label records from the late 70s actually go so far as to credit these devices by name in the liner notes of the album. This was practiced in the early days of Aphex, when the devices were not even available for sale; instead, studios had to pay to rent the devices at a cost of $30 per minute of program material.  Consider what this meant.  If you were mixing, say, a 40-minute rock album in 1977, and you wanted the ‘aphex process’ used on the whole record, it would cost you $1200.  Which is $4300 in today’s money.  Wow.  Imagine if plug-ins were rented this way today.

I used one of the cheap-o ‘Exciter C’ units back in the mid-90s; it was a good way to compensate for the poor sound quality we experienced when bouncing down tracks on a 4-track cassette machine or the TSR-8 tascam 8-track.  I later replaced the Aphex with a slightly more advanced BBE 862, which operates on somewhat different principles but offers a very similar overall effect.  I still find the BBE useful in the studio; not for the ‘exciter’ high-end boost, which sounds very brittle and artificial, but for the powerful low-end enhancement it offers.  I imagine the plug-in sounds much the same.

Although Aphex may have brought significant advancement to the field of ‘psychoacoustic processors,’ of which the Aural Exciter is certainly one example, they did not create this product category.  Several devices were available as early as the early 1960s which promised dynamic, program-dependent equalization of audio material.

Once such example is the Fairchild 673 “Dynalizer” Dynamic Equalizer.  In an excerpt from an excellent post on Pro Sound Web, noted audio-expert John Klett describes the 673:

“673 “Dynalizer” Dynamic Equalizer – does a Fletcher Munson Loudness curve equalization and boosts highs and lows as level drops – like an automatic loudness control. This uses the same optical system as 661 and 663… kind of slow and stupid but – who knows – possibly useful as a “thing”. You would have to get the gain structure around this right to make it work “well”.”

In the download, you can also find information on Aphex’ small line-up of API-500-spec processing cards: the EQF-2 equalizer and the the CX-1 compressor.  I have never used these units personally, but according to this website they are in fact compatible with the API-500 standard.

Broadcast Compressors etc. Circa 1974

From Collins Radio 1974 catalog #74: A round-up of broadcast compressors from Collins and CBS.  Models covered: Collins 26U-3 limiter, 26J-3 compression amplifier, CBS 4100, 4450A. and 4110, 4000A limiters; CBS 4500 dynamic presence equalizer; and CBS 710 ‘automatic loudness controller,’ which I imagine is some sort of LFKS-type limiter?

Also – a bonus – from the same era –  second-hand limiter/pre-amp price list from the same era.  RCA BA2Cs for $20?  Yes I will take 30 please.  How about a General Electric BA-5 for $75?

DBX 900 series outboard modules circa 1983

Download the four-page 1983 DBX 900-series catalog (plus a period DBX pricelist):

DOWNLOAD: DBX900_series_1983_catalog

The DBX 900 series has been mentioned a few times on this site.  These are great little units that can add a lot of processing power to a studio for very little money and space.  At a time when the API 500 series has come into serious vogue, with modules selling for $400- $1500, you can still fill out a 8-space DBX frame for a little over a grand.  True, they are not transformer I/O units, but I use these things all the time and they do the job.  Quiet, clean, and very reliable.  Not the most exciting sounds, but if you need an extra 8 compressors…  you got ’em.

The 902 De-esser module (at left) is the only piece from this series that has attained ‘classic’ status, and it is an excellent De-esser.  I often use the 903 compressors for Tom mics and I’ve been pretty satisfied with them.   I’ve had my setup (two gates, five comps, one desser) for about 10 years and it has never hiccuped.
