cambridge electronic workshop console

rebuilding this cambridge electronic workshop console.
it will be 14 channels into 2 stereo mixes with 2 pre/post aux sends. there is talkback facility to aux 1. there is a small speaker p.a amp on board. there is a complete control section. her he is all taken apart with new and old circuit boards arranged onto mothers – almost all ready to be reassembled and wired . next weeks task.
i rescued this desk in melbourne about 1996 from the infamous RAY EMERY – he was a sound guy of years and years who had a house in the sticks piled high with old tech of all sorts. he was an awesome guy who was very generous with parts and infos and rum. the other desk i could afford at the time was a mackie style . i hated those measley thin heaps with zero headroom and bad eq. i.e no fun.

so i bort the cambridge and a heap of other bits off ray and slowly remade it work and have used it ever since in my studios.

the cambridge is all transistor from around 1975. just before chip amps became normal to use in consoles . i.e the burying the good clean audio signal with multiple multiple stages of chips each with a gazzillion transistors each. those cheap mass produced consoles are major electronic bullshit.
ive never found anyone who has ever heard of the cambridge audio workshop. so this must have been a prototype – originally designed to be a special functional theatre console.
the cambridge transistor operational amps are very neve ish .. 1070 thru 1080 like. the similarity is bonkers. they utilise different sex power supplies and opposite polarity bi polar transistors .. and yet they can live on the same circuit board. it’s a mystery wraped in enigma

neevertron

neevatron1

neever535

ekadek neevatron. here’s a drawing for a new six channel microphone.direct amplifier .
the guts of it is three of the last (in the world) five NEVE B535 dual line output amplifiers – n.o.s original right out of  the 1970s – another world.

the neevertron features real simple functionality.  mic pad – phantom power – phase changer -  fantastic clear sound.
there is a negative feedback stage gain adjusting control which allows to set how hard the preamp works on the input signal.
the output signal volume control  chooses off a good proportion of that and feeds the totally juicey B535 line output amp.
an uber fat lo lo Z isolated balanced output is fresh made.

roger eq off to big smoke

off to the big smoke tomorrow . this new roger 3 ways very  flash all transistor dual channel eq. features
neve 1081 style 5 frequency high  and  low frequency control stages.  very  fat and sharp . for a deep deep sound. teamed with a freaked out sweeping midrange stage. boost or cut   200hz – 6Khz he has double series band pass filters for a  tightest Q potential. with  selectable band pass gain effects .
1.  normal      NICE and clean
2.  sharper q     Q.TIGHT
3.  turbo sharp     INSANE
hook this baby to a mad playable keyboard and a echo box and u could have a mother of a synthesizer sound. learn to play it like one thing and freaking shit. thats a real  human electric direct sound! right there. one take.  the circuit board  contains cards of electronics arranged as two in line channels. left to right . treble – midrange – bass – output. each stage contains perfectly simple fat A-class inverting amplifiers made of just four transistors. no chips. plus.  quite a bit of  specified frequency selective boosting cutting circuitry is in there on the mother too. . it’s the prototype to a unit that can make a few of. or maybe a more largess thing  for DJs .. that item would need preset-able fitments and lets make it  xfade-able thru a delay effect loop. to create some very far out transitions. the all transistor circuits make it clear and fat and low low noises with richness and real balls.

kaimaitron 4 channel amplifire

custom kaimaitron 4 channel  mic/instrument amplifier with internal /external source control room or headphone monitor section. built all of  transistor amps into a 1960s brown leatherete portable case . also features an insert-able   germanium amp stage which can be sweet or stinging.

cat visconti arriving

the cat visconti channel is almost gasp. complete.  just waiting now for a final bit of metal worked rear ass covering solution . sounding perfect . it’s made to be a best quality mono recording channel with mic/di/line stages and 4 way eq and filters with processor insertabilty. the output of that can mix (or not) with two stereo line inputs. the listenator function runs either the alone channel or the mixture of the alone channel with the stereo inputs -  into one of two selected pairs of speakers.  alla fenkner functionality.

new mini fenk

a new minifenkner contol room monitor ‘special’ dog. .  this little guy has been borned  inside a  pretty tight upgrade budget   so i found a suitable sized hammond industries cut folded & spotwelded chassis .. costs way less than my first   ‘built like a hummer’  styling. .   this  little bugger still has the same super clear and fat  transistor electronics as the luxury model of course  .   and…   two.   stereo  headphone amps .    all transistor superbness and very desirable functionality. get a  little mini fenk so to hear everything!   in your signal and throw it easily around your speaker systems -  to test your balances and ease your mind.

commando design preamp

the commando is a naked preamp with no annoying reach around issues.  read on.  its inputs and outputs and controls are all all right there up front.  .  perfect. theres no reach around issues.  its actually a  lot  easier  and efficient to assemble all the components of this multichannel  preamp on one surface. then u can build a chassis with a power supply in the corner  -  totally prewire a whole amplifier circuit unit of pretested channels.  -  pre assemble the control and interface parts onto the  clean conductive panel  -  stop for  lunch -  make the grounding  sheilding conductivity of the panel / chassis / cabinet.   – trim and attach all the wireing to the controls and switches . and boom. turn it on .   almost dinner time. (i wish) but actually very efficient.  very easy to be super tidy.  all the wireing at the inputs is as short and direct as possible. more like a point to point style construction.  more robust too.  nothing  flimsy – just  strong hardwired connections. the amplifiers themselves are the sexchanger transistor designs.  simple tough hi fidelity amps from the late seventies.  yes they are quiet running and super fat gain cells. big and clean, and yes .  they can distort if you push them. there is a fine cross adjustment between level in. amp stage gain , and pickup amp volume. well worth the journey. the quad unit contain  two stage amps. im considering a three stage design – for super clean super full on 80 db gain. or beastly extra fucked up distortion. extra squared square with your square.

dressed best DJs in the world

classic set up . 1200s.pioneer mixer. and a monoman running the big mono kick ass speaker stacks.

ruggedtechniques .  hal smith stevens has been visiting me for years now. he is always so enthusiastic and charming. and extremely talented.  and one day we’ll get to work on a major major project together.

my god man !  dont hurt yourself with that contraption.

it might be a crazy musical  technical adventure that is biblical. or  it may even  be a technical musical product thing that is functional AND biblical.

dont worry kind groom.  we are completely trained for all complications.

he got formally hitched to a wonderful girl and threw a very special  party at alberton.  it was an awesome event for hal and kirsty .

yyeeaahh.

everybody had a great time and of course the good djs were impeccable

wot the blighty chaps . we have sullied this LP record surface with our party antics.

toby muir with his big monoman mono pa system out to play.  … sounds  rude actually .. but he was very well mannered about it all.  the monoman unit contains a valve preamp -    4 system output distribution amplifiers -   and a 4 way adjustable speaker amp xover amplifier splitta unit. all transistor circuits . its way expensive so forget about it.  it does so much that we dont know what even to call it other than the monoman.

two portable fattys

two quick builds this week.  small and fat. the akai-ish playback unit now has a line input suitable for ipod or computer plus a hi impedance input so u can jam along with a guitar, keyboard or hi z mike .  the  5 watt tube amp and 8 inch speaker has a lovely full clear sound, and can distort like a nasty bitch on demand. the lower box is a two channel all transistor mike/di amplifer  -  custom built into a beaut old phillips tape recorder box.

ten8tor gyrator 100% love

heres the word from mastering engineer and serato minion wrangler -  zebulon bult .

Hi Greg,
thanks for lending me the TEN8TOR, I got excellent results out of it & I really can’t praise this EQ enough, it sounds wonderful!
Here is some feedback from my experience with it.
EKADEK GYRATOR TEN8TOR
I used the EQ in two different ways, tracking mono & stereo drum sounds/instruments. I did this from an MPC 3000, into an Apogee Duet 2.
I also recorded several stereo mixes through the TEN8TOR, I did this from an Apogee Duet 1 into an RME FF800 & also from an RME ADI 8 into a FF800.
Tracking
The results I got from tracking the drums were good. It was easy to add presence to all sounds, even if subtractive EQ’ing was necessary in some circumstances. I found it noticeably worthwhile to just track through it without gaining or reducing any particular frequency range, because it added warmth & presence. The filters sound smooth & rich but also clean & open, very musical.
Mix Bus
The mixes I was recording were coming straight out of Logic 9 & in this workflow, it really shined. It became clear to me that this EQ was nothing less than mastering grade & it had a special character. I did not use it in conjunction with my summing mixer, pultec EQ or compressor/limiter. I went straight from a stereo D/A, into the EQ, then back into the A/D. I found I was very quick in finding a no compromise mix adjustment. The TEN8TOR can add a subtle brilliance to a good mix but it also has the ability to make a rough mix sound more punchy & defined, also polished, without the obvious issue of major compromise. It’s obviously not intended to be a transparent fix your mix tool, but was surprising ly good at dealing with less than satisfactory material. The best possible scenario for this EQ is obviously a flat, well mixed track that allows you room to push it. It was a pleasure to use the TEN8TOR & I would love to have one permanently in my studio.
Pro’s:
Sections & their parameters are well spaced out with plenty of room to move.
Top quality switches and pots, large knobs that feel great to use
Thick and warm tone that is musical all the way through it’s range.
Low noise, even with hi gain, especially when you take into account that it’s unbalanced.
Total bypass and band bypass
Peak and Shelf Equalization

Con’s:  (ekadek : fair enuff that zeb didnt like some stuff. thats ok . but its my blog so i’ll chime in  if i want.) The back panel lacks rigidity when connecting & removing cable jacks.  (fixed that.one screw – thanks for pointing that out :) Stepped pots for filters restrict the ability to make real time filter changes  (yes – the steps mite sound a bit odd. the special filter electronics are such fine tuned up resistor sets. u cant make a 6 gang pot that does the 6 different values and curves for under about a bazzillion $ each )  Unbalanced, more susceptible to noise.( transformer balanced is good . transformers just make it cost more) Low to Hi frequencies from right to left, this took a little while to get use too.  (fair enough – i like it that way tho -  when u turn it on its side, it becomes a perfect XXL extra huge large format console channelstrip . 4 – 8 – even 16 of these babies in a big desk. so cool and expensive. my fantastic console dream .  and it encourages/requires a different intell approach – method – style – what have you. its fresh. )

thanks zeb. the gyrator ten8tor has gotten 100% raving reviews so far. we are in love. theres just one left for sale now.  and we are  in prep  for a second limited run version two after christmas.

gyrator ten8tor testimony

i helped chris shelswell of  DREAM CONFIG with the recapping of a TAC mixing console and the get-going of his control room.   he played with our ten8tor prototypes early this year, and  loved them.  he spurred us on with some cash and now a new made one developed up to it’s eyeballs – sits proudly in his studio. and he was kind enough to write these words.

“I really have nothing but positive things to say about the ten8tor. It looks fantastic. Really nice big chunky knobs make it a pleasure to use. It feels like I imagine it would to operate an old russian submarine. Every day I pull the cover off it gives me a smile. Then there’s the sound, I swear simply plugging it in makes things sound better. There’s buckets of gain at the input and the 2 mid range knobs give you a massive degree of control. The high end is sweet and smooth. You can really “over do it” with out ending up with that horrible broken sound you get from lesser eq’s. There’s really a huge amount the ten8tor has to offer. With 4 bands and the high and low filters I wish I had one for every channel on my sound card.

I bought the luxury ten8tor as a mastering equalizer for it’s beautiful stereo sound and control but it’s very much become my main eq. I use it for everything from processing single tracks, overdubbing mono or stereo instruments to completely effecting the sound. The ten8tor is amazing for perfecting a sound subtly,  or to powerfully change it.”

and just about was i to post his testimonial a few days later when he wrote again.

“Just did my first mastering job with the ten8tor – It was really a pleasure. It’s a beautiful eq to use and made an amazing job on the track. I couldn’t ask for a better eq :)

monoman lives!

this whole package is ready and banging. so im looking forward to plugging the bugger into the big 100KW pa system. ive been playing records thru it . and distributing  out into the radios and grams and monitor amps ive got around this room. sounds awesome to change the focus of parts and flavours of audio and seemingly fill up a space with very delicate shifting tones. dont get me started. im all about that shit. i’ll put a little thin eq and a slow echo in one speaker way over in the corner – and a bassey round tone with a phazey squeal in  a speaker over the other side. fill in with the mantle radio left reverb and blaster for the right flat flat  … and hell. youve got a hell over a flavourfull sound.  you can pop the vocal out of the 8″ woofer or the 1″ tweeter.   good for much more trickery pokery than that gay sounding example . OR just easy-peasy-by-ear  sweet sweetening of the classic 4 way stack.  i need another beer.  given the bar space i could tweak the surround sound of music into the eeriest experiential ….  altering state happening.  something to really turn the ears on.

monoman progress

igor spent the day testing and tweaking his filter circuits. 4 eight pole switches controlling 12 active frequency filtering operational amplifiers.  an uber complicated device with a few hundred things to potentially get wrong.  igors dam good and smart tho and they sound awesome.  4 clean bands. sub- bass- mid- hi with sweepable crossover frequencies. it will no doubt become our new studio mastering sound splitter equaliser.  a stereo control version would need 16 pole 5 position switches. woof. and it will eat your computer for breakfast. late last nite i got excited and rough assembled the front panel to see what it was going to look like…. and it looks pretty cool i think.  so absolutely unique. but this morning  i scuttled our progress totally. after noticing some paint spottiness. well.. it actually looked like someone had spit up on the thing. and we cant have that can we. so its all dismantled now for a few days while that gets redone.  gives me time to  admin and fix the car and mow the lawns and the dishes.
