"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] "

Modcan DUAL FS 65B

via Modcan where you'll find samples
"As with many modules in a larger system "One is good but two is better". For Frequency Shifters the Dual FS 65B is a two for one
and includes Ring Modulation and phase effects modes as well.

The 65B is an entirely digital interpretation of the standard Bode Frequency shifter model which achieves numerous significant benefits over its analogue predecessor, primarily the dual configuration.
Other advantages include stable low distortion quadrature sine carrier for accurate sideband generation, digital math eliminates feed thru error found in typical analogue multipliers . No need for squelch circuitry. Other benefits include absolute stability at low shifts, low noise signal path and zero maintenance calibration ...EVER. There are probably only a handful of Bode FSs in the hands of users that are ever within factory specs at any given time due to complicated and costly calibration procedure. With the 65B that will never be an issue and you will always have an accurate and precise instrument regardless of ambient temperature or age. Analogue Frequency shifters still maintain superior high frequency response over digital but due to the nature of the effect the difference is small.
Another important consideration is that it would be both cost and space prohibitive to implement a matched set of dual FS in analogue with similar features and performance.

The real fun begins when the two independent FS sections are internally patched in series and parallel configurations via the mode selection control. This allows for some seriously altered stereo effects with near 3D results.

Module Highlights:
* 2 independent Frequency Shifter channels in one package
* 11 modes including FS, Ring Mod and Phase effects
* CV and 1V/oct control of shift
* On-board internal feedback controls for each channel
* Clip indicators
* +/-5kHz Exponential Shift range
* Through Zero operation
* High Quality Codec
* 16bit Audio
* Zero calibration maintenance
* 20Hz-20khz response
* Modest current consumption
* Firmware by Eric Brombaugh

Specs:
Sample Rate: 45kHz
Sample Resolution: 16-bit
Output: typical 2V RMS@1Kohms
Input: typical 5V pk-pk@100Kohms
Input CV: 0 - +5V @100Kohms
Power: +15V @130mA, -15V @20mA"

1630 Bode Frequency Shifter

Rare Vintage BODE FEEDBACK STABILIZER

via this auction
"Up for auction is a rare BODE 742XR "Feedback Stabilizer". Apparently, this is a variation on Harold Bode's "Frequency Shifter" design (as used by Moog in the coveted Moog modular series).
This version was originally geared towards feedback suppression applications (hence the name), and was generally used for live sound situations. I'm told that it has potential for modification into the "frequency shifter" zone, but, haven't really looked into it further. I DID, however, put signal through it, and it does seem to alter the audio (a phasing "tremolo" effect, of sorts), albeit subtle. The potential for modding it to do more seems to be there, but I'll leave that for the next owner to figure out. Generally, it does seem to work as originally intended, but could probably use calibration.
On the back are two empty sockets for line input/output transformers, which were offered as an option (which would be accessed via the barrier strip on the back of the unit) but are not necessary to the functioning of the unit, as the inputs and outputs on the front are the "normal" connections. Here's a link: http://www.vasulka.org/archive/Artists1/Bode,Harald/FeedbackSynth.pdf"

via the seller: "THIS IS A ONCE IN A LIFETIME OPPORTUNITY FOR ANYONE TO OWN ALL THESE UNITS WITHOUT HAVING TO WAIT YEARS & YEARS TO FIND THEM ALL... IT TOOK ME MANY YEARS TO FIND THEM ALL AND SPENT LOTS OF MONEY ON THEM PLUS ALL THE ELECTRONIC MAINTENANCE I HAVE GIVEN TO EACH ONE OF THEM TO HAVE THEM WORK ALL 100%.

I have 5 units in a robust ATA Molded PE Shock w/ Rubber Shock Suspension (12U Space) Model: G-Shock-12L almost new with both front and back lid covers with it's own locking key as well... (REFER TO PHOTOS...) And the Moog Parametric Equalizer as a single unit because it didn't fit in the case unfortunately... But you get all 6 units shipped together as a complete set... NOTE: On the last picture the Bode Frequency Shifter, Bode Vocoder, and the second Moog Parametric EQ ARE NOT included in the bundle they are there just because that's where I had mounted both Parametric EQs but you only get one of the Parametric EQs and not 2 that are pictured there along with the other Bode stuff... Although the Bode Units are going for sale as well but are being sold separately so please refer to info description or ask questions if you're not sure. Thanks...

Here's what's included in the bundle:

- Moog 16 Channel Vocoder 327A - Model: MBVO - X 1 Unit
- Moog Custom Engineering String Filter - ( Fully Calibrated...) - X 1 Unit
- Moog Custom Engineering Dual VCO - ( Fully Calibrated As Well...) - X 1 Unit
- Moog 12 Stage Phaser - Model: MPKH - X 1 Unit
- Moog Three Band Parametric Equalizer 304A - Model: MKPE - X 1 Unit
- Moog Ten Band Graphic Equalizer - Model: MKGE - X 1 Unit

Here's some info you may want to know about each unit:

* Moog Dual VCO - The Moog Dual Voltage Controlled Oscillator was built in very limited quantities by the Moog Custom Engineering Department A.K.A. Modusonic which has 2 Ultra-Stable VCOs based on the 3rd Revision of the Minimoog 921A VCO With Temp Comp UA 726 Matched Differential Pair Transistors. SUPER FREAKING PHAT..!!! Personally I think it beats any Minimoog I've own... The waveforms are just "EARGASMIC"... =) You've got to hear it for yourself... The Moog Dual VCO was designed to add that extra two oscillator fatness to other Moog Synthesizers as the Multimoog, Micromoog and the Minimoog at the time; although the Minimoog required the addition of the Keyboard CV Output Modification so it could control the Moog Dual VCO's pitch and route it's output back into the Minimoog's External Audio Input... The Micromoog & Multimoog did not require this mod because they have already a Keyboard CV Output Jack as well as their respective audio input. So basically you can use the Moog Dual VCO with any Analog Synthesizer with a Keyboard CV Output (1 Volt/Oct.) and an External Audio Input to pass the Dual VCO's output signal back in it and voila two extra fat Moog Oscillators in your set up.

* Functions, Features & Input/Output Option:

- Master Tune - Controls overall tuning of both oscillators or one when only used as single...
- Pulse Width - Controls width of both oscillator's pulse waveforms when used either as single or dual.
- Octave Select Multi-Switch Knob with: LO, 32', 16', 8', 4', 2'. (Both Oscillator 1 & 2 have their own Multi-Switch Knob)
- Waveform Select Switch with: Up Ramp/Sawtooth, Triangle, Pulse, Sine.
- Oscillator On/Off Switch - Each Oscillator has it's own on/off switch to quickly add or subtract one oscillator while performing.
- Oscillator 2 Sync Switch - Automatically syncs both oscillators together by the flick of a switch.
- Oscillator 2 Tune Knob - To tune or detune oscillator 2 from 1 either while synced or un-synced.
- Output Level Knob - Controls overall output volume.
- Power Switch - Turns on/off unit.
- Oscillator 1 CV Input Jack 1/4" (1 Volt/Oct.) - Controls oscillator 1 only.
- Both In 1 CV Input Jack 1/4" (1 Volt/Oct.) - Controls pitch of both oscillators while oscillator 1 being the master controller.
- Oscillator 1 Output Jack 1/4" - Outputs signal of oscillator 1 only.
- Oscillator 2 CV Input Jack 1/4" (1 Volt/Oct.) - Controls oscillator 2 only.
- Both In 2 CV Input Jack 1/4" (1 Volt/Oct.) - Controls pitch of both oscillators.
- Oscillator 2 Output Jack 1/4" - Outputs signal of oscillator 2 only.
- X 4 Multiple Output Jacks 1/4" - Note: These are not connected whatsoever to any circuit inside the unit, they only serve to split any input or output signal you wish to multiply.
- Runs on 120 VAC Only.

* Moog 16 Channel Vocoder - The Moog 16 Channel Vocoder was designed by Genius Engineer and Pioneer In Electronic Music Instruments Harald Bode in the mid 70's about and first released in about 1977 under the "Bode Sound Company" Brand which was manufactured by Polyfusion under the name of Bode Vocoder 16 Channel Model 7702, and was then licensed to the Moog Synthesizer Brand in about 1978 which was then released as The Moog 16-Channel Vocoder 327A Model MBVO. Both Vocoders are almost identical in circuit design except for a few slight variations in the type of components that were used in each but functions and features are basically the same...

Bode Vocoder Model No V-7701

via this auction

"It doesn't get much rarer than this groundbreaking and historic vintage vocoder.

The Bode design was licensed to Moog for their vocoder, the only real difference being the rebranding.

Harald Bode was a pioneer of electronic instrument design and responsible for many of the circuits and concepts we take for granted today. Most of his designs were incorporated into products for other companies (Estey, Wurlitzer, etc) but the most revolutionary bore his own name. The Bode Frequency Shifter and Bode Vocoder are arguably to most coveted of these. The model 7701 is a very rare of version of the already incredibly rare Bode Vocoder. I have never seen another and it may have been an early prototype build though the build quality is top notch. It is entirely likely this is the only one or one of only a handful of units made.

This unit is working and sounds incredible."

Update via Guido on AH:
"Let me bring everyone up to date on my Buchla saga.

I bought a very large Moog from a gentleman in California for $13,500 shipped.

I took a Moog 15's worth of modules out of the system along with a Bode frequency shifter and the 960/962 combo. I already had a fire damaged 960/962 along with a Moog filter bank and a 921 oscillator bank.

I made a Moog 15 and extension cabinet with the "good" 960/962 and the Bode.

I traded Paul a "Moog 55's" worth of modules straight across for a large Buchla 200.

Only three Buchla modules were damaged by the coke or coffee spillage. The 219 keyboard and both Marfs. I sent those to JL in Canada who, after six months, had not gotten them to work. So I sold them...not working...to a gentleman in California for $11,500.

I had aquired 3-259 "kits" from Don and had Julie Yarbrough build them for around $1000 each. I also had her build a 281 "kit". I put those in the 200 along with my 208 and 218 from my Music Easel. She also refurbished the other modules for around $2500 or so. I then aquired two more 259's from David Kean for $5000. I eventually sold the original Buchla built 259's (for what I paid) because the "kit" 259's sounded, worked and looked better.

I had Peter Grenader build a Milton for the Buchla. This was around $2000. I also bought a 221 touch keyboard from Kean for $4000.

I used the system for two years or so and got an offer I could not refuse for it, minus the Easel and Milton, for $46,000. I took it. I then sold that same cat my Milton for $1750. I also sold the Moog 15 for $7500 and the 960 extension cab, MINUS the Bode, for $5500.

I sold the Bode to a very persistant gentleman in California for....$6,000!

So let's do the math:
I bought-
large Moog $13,500
Moog filter bank $1750
Moog 921 bank $2000
2 Moog 15 cabs $500
Buchla restoration/modules $5500
Buchla 221 $4000

Total $27,500

Traded a Moog 55's worth of modules for the 200.

I sold the Moog 15 for $7500. Sold the extension Moog cab for $5500. Sold the two Buchla modules for $11,500. Sold the Bode for $6,000. Sold the big 200 system for $46,000.

Total $76,500

I still have the Easel. I also aquired a mint Moog 35 last year, so I still have a "rig".

I hope this brings everyone up to date on my Buchla 200/Easel and financial gossip.
