4 Early installations havenow been in use for well over thirty years, andalthough the details have evolved as improvementswere made, the innovative yet simple modular designpioneered by Peterson in the 1960s still makes this afavorite for many projects today. The quick response,maintenance-free reliability due in part to its lack ofmoving parts, and silent operation all contribute to thissystem s phenomenal success. For many applications,the relatively low Technology level of diode matrixmeans less cost than with multiplexing and computerbased systems. This product is credited by many fortransforming the way electric action organs are con-trolled throughout the pipe organ Peterson Diode Matrix Switching System is acustom built electronic panel for performing the keyswitching and stop control functions of a pipe to work with any wind chest having an electric action, it is equally applicable to electro-pneu-matic or all-electric types. Stops can be straight, or anydegree of duplexing or unification can be Matrix Switching Systems consist of a numberof modular assemblies of solid state componentsincluding transistors, diodes, integrated circuits andresistors on one or more panels designed to mount in or near the organ chamber(s).

5 Specially designed disconnectable junctions allow the various modules to be factory tested and assembled. At the time ofinstallation, the installer simply wires a cable from eachchest to a connector provided, which is then pluggedonto its related assembly. Similarly, single switch contacts associated with the keys of each playing manual, the pedal board, and from the stop tablets,must be wired to connectors which also plug in asclearly labeled. Other than the above, the PetersonSolid State Switching System is supplied completelywired, tested and Peterson Solid State Switching System originated as a modern substitute for mechanical relaysthat could offer much higher reliability with virtually no maintenance. With solid state, thousands ofswitch contacts are replaced by semiconductor devices,which can never pit, corrode or require adjustment. All components are sealed against humidity, dust andother environmental factors. Except for one contactper playing key, and one contact per stop control,there are absolutely no contacts to ever require adjusting or cleaning.

6 Because there are no movingparts, there is nothing to stick, bind or make for the movement of the stop tablets and theplaying keys, the action is totally silent. It is indeedstartling to push the Sforzando piston and have the full organ appear without the slightest attendant the solid state switches operate at the speed of light, the action is totally responsive without the lag that is frequently associated with mechanical the playing keys must each operate only a single key switch, the loading on the key is insignificant,and the key tension and type of return spring can beselected and adjusted for the best possible feel. Key contact reliability and durability is enhanced inthat the key switch current is less than that required byeven a single chest magnet; in addition, it is non- inductive. This means no contact sparking .. never anypitting or burning. Finally, because there are no actionDiode Matrix Switching SystemSolid state coupler/relay for pipe organsModular design.

7 Low tech electronic of proven reliability inthousands of cost for easily expandedor totally configured, tested and to constantly consume power, a much smallerand less costly rectifier can be used. The total powerconsumption is essentially that required to operate thechest magnets. With the Diode Matrix Switching System, no special power supplies are required, and a regular 12 to 18 Volt organ rectifier may be used. Voltageappearing at the chest magnet is about one volt lessthan the voltage at the rectifier. As in any organ, theminimum voltage required depends on the characteris-tics of the chest magnets. Polarity is important and normally the key switch feed must be positive. Thestandard stop tablet feed is positive, with negative available by special order. Where couplers are used, a separate solid state coupler system may be mounted in the console or in the organ chamber. When certain features arerequired, a Peterson OrgaPlexTMcoupler system isoften used with a Diode Matrix relay.

8 If desired, a conventional console having mechanical couplers can be connected in the usual manner. Where anyPeterson Solid State Coupler System is used, eachplaying key operates a single key contact, which controls all modular design of this system, together with its unique proprietary connector system, allows unlimited future additions or changes with no preparations and with no cost penalty. It is also practical to add a Diode Matrix System to control new ranks that are being added to an old organ with an electropneumatic or other existing Peterson Solid State Switching System includes a Sforzando terminal which, when energized, turns on all stops. Any stops not desired in the Sforzandocombination may be deleted by clipping a wire orunsoldering a connection. The provision of theSforzando terminal saves the very considerable cost of special Sforzando switches and wiring that was traditionally operation of the Diode Matrix relay is remarkably simple.

9 A comprehensive technical manual, which describes in simple terms how theequipment works, is supplied with each system. Even without this resource the modular concept, logical layout of the various components, connectorsand built-in test junctions make trouble shooting easierthan with most other relays, electronic or , for example, the common cross or run where two or more notes sound together. Usually, the short circuit causing this can be in any of severallocations, but with the modular concept, the variousassemblies can be quickly disconnected from oneanother and the trouble immediately and connector terminals are mounted on special printed wiring boards in octave groups sothat the parts related to a specific function are readilyidentified. While a complete system necessarily lookscomplex, a more careful examination shows it to consist of a large number of identical, very simple, easilyunderstood circuits. Any technician who can find hisway around a mechanical relay will quickly feel at homewith Peterson Solid State.

10 Each type of Peterson control system has advantages for particular organ specifications. ThePeterson Diode Matrix Switching System is often less expensive on small organs with all or most of theirranks straight rather than unified and where features such as a transposer, MIDI interface and/or a movable console are not required. In some cases,Peterson will recommend a hybrid control systemusing OrgaPlexTMcouplers connected to a Diode Matrix Switching System to operate the note s technical staff will be happy to discussoptions and pricing with Voltage: 12 -18 Common Common Polarity:Standard is positive; specify negative when ordering if Return Common Polarity:Standard is negative; inquire if positive chest returns are Load Ratings:Please specify the locations and resistance of all magnets below 50 Ohms.

This means that the on and off status ofmany related controls, such as all the keys of one key-board or a large group of stops, are repeatedly scannedat high speed, then processed and transmitted withinthe system on essentially a single wire.
