Analogue Systems RS240 Bode/Moog Frequency Shifter

Note: Auction links are affiliate links for which the site may be compensated.

via this auction

"The module has been infrequently used. There is some rack rash as shown in photographs. This listing is only for the RS240 Module and the Doepfer to Analogue Systems power adapter in the power connector, see photo. It does not come with a power cable. The module functioned properly when I tested it last week. The module is not specifically in a Eurorack format (see the Analogue Systems website), but fits nicely in a Eurorack case.

With regard to the adapter to allow use of a "Doepfer" style power cable be sure to align the red stripe on the Doepfer power cable with the end noted "Red" on the PCB. There is also a red stripe on the adapter. It works fine with the +/-12 and +5 volt supply from a Doepfer power supply.

If you are not familiar with Analogue Systems or this particular module, I suggest going to the Analogue Systems web site for more information and the manual. Big City Music also has a listing for a new module with a link on their page for an installation guide.

Analogue Systems

This is an amazing and accurate reproduction of the original Bode/Moog 1630 Frequency shifter in a wonderfully compact form. It has all the features of the Bode/Moog 1630. One very nice and notable behavior is there is no "dead zone" when shifting through zero. Many (all?) the original/vintage Bode/Moog 1630 Frequency Shifters exhibit an annoying dead zone when shifting through zero (I know that at least one of the modern clones has a "dead zone" as well*). That is, the shifter stops shifting the frequency creating a region where no shift occurs as one approaches and moves through zero. The Analogue Systems RS240 doesn't do this. Rather, there is a smooth transition through zero which is far more useful and the correct behavior.

SynthAl on YouTube has a short video which seems to show this 'dead zone.' [see here] "

1630 Bode Frequency Shifter

SYNTH-WERK Introduces SW 1630 BODE FREQUENCY SHIFTER & SW 735 Rack Version

via SYNTH-WERK

"After long and intensive research & development work we are very proud to announce our newest creation, the SW 1630 & 735 BODE FREQUENCY SHIFTER. The first batch of 10 units is already build and sold to our friends from the waiting list.

From today on the Module is available and can be ordered.

Price:

SW 1630 BODE FREQUENCY SHIFTER : 1.950 Euro + TAX
SW 735 rack version: 2.150 Euro plus TAX"

FUNCTION DESCRIPTION
A frequency shifter is an audio signal modifier which shifts the entire frequency spectrum of the applied signal by a given amount. The Model SW 1630 Bode Frequency Shifter allows the amount of shift to be accurately and continuously controlled over a span of -5000 Hz to +5000 Hz, utilizing voltage and/or manual control. The relationship between the control voltage sum and the amount of shift may be either linear or exponential. Up-shifted and down-shifted outputs, as well as a continuously variable mixture of the two, are available simultaneously and independently. Variable threshold squelch and zeroadjust fine tuning controls are provided.

The Model SW 1630 Bode Frequency Shifter changes the ratios between the frequency components of an audio spectrum, thus producing a variety of novel sound quality transformations. Applications include a wide variety of tone color modification, P.A. feedback suppression, linear frequency modulation, novel tape feedback effects, and the generation of dynamically varying clangorous tones.

MUSICAL APPLICATION
In shifting the components of the input audio spectrum by a given amount, the SW 1630 Bode Frequency Shifter changes the original ratios between the overtones and other frequency components of the input signal. Rather than being a transposing device, this instrument is a means for achieving an extremely wide variety of tone color modification. Whether the amount of frequency shift is large or small, static or time varying, or whether the input signal is simple or complex, the processed outputs will generally be musically interesting."

via this auction

"This is a used Club of the Knobs - COTK - C1630. A clone of the Moog 1630 Bode Frequency Shifter. A really stunning module that has all the behavior, quirks, and richness of the original. I just want the rack space for other modules, like a COTK envelope follower, and a couple of others I'm thinking about :)

This is used. Built in November 2013, delivered in January or February of 2014. Serial number C 2538. It consumes 3U in width and is a full height module compatible with any Moog style cabinet format.

I've been using it with a Synthesizers.com QPS5 power supply (inside is a Power One linear supply) connected to a COTK power distribution strip. I've had no problems with this setup, but you will need to provide proper power for the module. See the COTK web site for technical details.

There is no "manual", but moogarchives.com has the instruction page from the original Moog manual.

You will get what you see in the photos:

The module;
The power cable; and
Three spare lamps.

The lamps aren't hard to find. You can get them in bulk from Mouser, singles from Synthesizers.com. I just think it's handy to have a couple of spares...

The last I checked, 5/5/2018, the new price was 970 Euros, about $1100.00 - $1200.00 USD, see COTK web site for pricing."

Bode 735 Frequency Shifter & Electronic Specifications

Note: Auction links are affiliate links for which the site may be compensated.

via this auction

"For auction is an extremely rare Bode 735 Frequency Shifter. This is a device designed by Harold Bode in the 60’s which was produced until the early 80s by his company Bode Sound Co.
This instrument is most well known for being repackaged and included as the Moog 1630 Frequency Shifter of the 1970s Moog Modular systems.

The Bode up for sale has been dated to 1972 and appears to use the same PCBs as the Moog 1630. These were hand assembled by Bode and are extremely uncommon outside university electronics studios.
I acquired this one in 2002 and was told at the time it once belonged to Vladimir Ussachevsky who started the Columbia Princeton Electronic Music Studio in the 1960’s.

CONDITION:

I have been collecting and repairing vintage electronics since the 1990’s, I have over 18 years experience as a restoration technician of high end and rare instruments and this is from my personal collection.
There has been no work performed on this historic device besides replacing the frayed power cable for safety reasons, the old cable will be included in the sale if the winner wants it. I found the identical vintage
style cable at an electronics supplier to keep this as authentic as possible.

There are no unexpected surprises here."

"Incredibly rare. This is the front panel with the switches, jacks, LEDs and pots only! This is not the complete module. This is a left over assembly from the original production, it was never completed as a module at the Moog factory. I received this in trade from a former Moog employee. Some minor marks on panel but otherwise in good shape. Being sold "as is"."

Bode Frequency Shifter cased & psu

via VEMIA

"Moog / Bode Frequency Shifter 1630 The Bode Frequency Shifter was originally designed for use with Moog modular systems. The sound of the Bode is unique – it produces highly complex waveforms by shifting not only the fundamental but all input frequencies by the same amount. The result: non-harmonic relationships between the frequencies in the output signal. This particular one comes in a nice wooden cabinet with a power supply (230 V), just as it was mounted and sold by Studio Funk Hamburg in the early seventies. Of course it can still easily be built into a modular system. The machine has been checked by a tech recently and is technically in a very good condition. The wooden cabinet shows minor signs of usage. A copy of the original (unfortunately not complete) description by Studio Funk in German language and some notes from the moog modular systems owner’s manual on the Bode are included as well."

Moog Bode Frequency Shifter model 6552 Owned by Walter Sear

via this auction

"This auction is for a super-rare rack mount Bode Frequency Shifter Model 6552 by R.A Moog. This is from the personal collection of Phil Cirocco of CMS / Discrete Synthesizers. This is a once in a lifetime opportunity to own a rare piece of electronic music history.

This is serial #1001 and is the very first Frequency Shifter produced by R.A. MOOG. This particular 6552 was once owned by the great Walter Sear. It features ring modulator diodes that were hand selected by Harold Bode himself! It is listed in the Moog Archives http://moogarchives.com/ on the left menu select: "lists and charts", then: "custom sales" then: "frequency shifter".

There were 2 major incarnations of frequency shifters made by Moog/Bode. The first one (model 6552) is the one you see here. It is all discrete and uses actual diode rings and transformers for its ring modulator circuits. The second version (model 1630) is an op-amp chip version that uses balanced modulator ICs for its RM circuits. The second version, while being more convenient, does not sound anything like the first version.

I can say with confidence that you will never see one of these for sale again in your lifetime.

This Frequency Shifter is in excellent condition. There are no scratches on the front panel. It is #1 out of a known total of 11 units made. It was made by R.A. Moog under contract with Harold Bode. It is all original and functions perfectly. It is NOT a clone and it has a valid serial number and pedigree. It was recently calibrated here at CMS. It uses terminal strips in the back as all early Bode rack mount units do, so you will have to use a patch-bay nearby."


This one in via Keld.

Update via Michelle Moog-Koussa: I heard from Michelle Moog-Koussa, Bob Moog's daughter and Executive Directory of The Bog Moog Foundation. She stated, "I'm 99% sure that the model number and serial number are written in Dad's handwriting.

This piece was issued on August 21, 1968. Thirty-seven years later to the day the frequency of the whole electronic music community would shift as Bob's body left us......."

360 Systems 20/20 Frequency Shifter (BODE)

via this auction

"This is a very rare item, probably the first I've seen one on ebay. It is a Frequency Shifter, model 20/20 by 360 Systems.

360 Systems was (and still is) an innovative company that developed this pitch changer (as used by Synergy/Larry Fast, John McLaughlin), one of the first guitar synths (John McLaughlin) the first sample-playback keyboard and many audio post devices since. They also developed the first LINN Drum for Roger Linn. Bob Easton was/is their clever designer."
360 based their design on Harold Bode's rare "Klangumwandler" that was made and sold for Moog in the late 1960s and early '70s.

The Moog/Bode 6552 Klangumwandler ('sound-changer', in German) was an interesting concept, to modify pitch (frequency) without changing the overtone structure. Bode's invention was first created for Ussachevsky's electronic music studio at Columbia University (Bob was quite familiar with the composer and studio, as well as his various students like Wendy Carlos. Wendy and Tomita used this module on their classic albums. Club of the Knobs synthesizers now make a very accurate replica of the original Bode/Moog module and you can see it (and the similarity to this 360 design) on their website. The 360 has the same "series of 5" settings (5,50,500) as the Bode - and mixed vs. independent outputs, although the squelch is internal on the 360 via trimpot. There is CV (Voltage Control) of the frequency - great with a sequencer, CV pedal (McLaughlin) or random. These are similar to a ring modulator, but have a VERY unusual effect at the lowest settings. This is the effect I love (and why anyone should own this) - a deep phasing in stereo, without "messing up" the sonic quality of the original signal - all bass a treble frequencies remain solid, and the harmonics shift around in stereo beautifully. It's weird but not ugly - very HiFi and cool-sounding.

BODE

some text from the web):
'... the EWE, which stands for Electro Wagnerian Emancipator. There's only one of them; it was designed for me by Bob Easton at 360 Systems… That is now gathering dust in the warehouse. I tried to use it on "Big Swifty" from Waka/Jawaka - Hot Rats, but it didn't end up on the final track." (BTW synth geeks - this is mystery item was basically just an EML Polybox, same idea!)

'We also have some neat little 360 Systems model 2800 programmable equalizers, which are four-band parametric with memory storage for saving any particular settings that you may like. Those were designed by Bob Easton and are no longer available, but we have a few of them.'"

Update via eben in the comments: "check out the comment in that ebay auction in the questions section - none other than Tom Rhea, author of the minimoog owners manual"

via the auction:
Q: Hey neighbor, interesting that you have a frequency shifter for sale, but your description that a klangumwandler shifts without changing the overtone structure is incorrect. Pitch shifting a la the Eventide Harmonizer does this; Harald Bode built frequency shifter(s) that provide a LINEAR shift in frequency (Hz) for all partials in the input signal. This will, of course drastically change the "overtone structure," not preserve it. Sorry to be a drudge about this, but I knew Harald well, teach this stuff at a well known music College," This message purely in the interest of sharing information. Hope you get a good penny. PS, I have several Bode 1630 FS (lucky me, but just knowing Harald was the real treat!) Tom Rhea (author Minimoog Owner's Manual, etc.) Good luck in the sale! Apr-14-09
A: Hey Tom - you are likely QUITE right. I only said it was based upon the Bode - which seems quite true given the controls and front panel, steps of "5's" etc. Obviously, the audio track given shows what this very unit does exactly, so no deception is implied.
