HISTORYGerman Engineering ExcellenceFOR MORE THAN 60 YEARS, DYNACORD HAS BEEN ONE OFTHE MOST INNOVATIVE AND SUCCESSFUL MANUFACTURERSOF PROFESSIONAL AUDIO EQUIPMENT.4

HISTORYIn 1945 Werner Pinternagel,who was an engineer, founded aworkshop for the repair of radiodevices in the Lower Bavariantown of Pilsting. The developmentand manufacture of audio amplifiers,which he began at the same time,became a particular passion.These pioneering experiencesformed the foundation for over60 years of expertise in professionalpower amplifier technology— expertise upon which the brandDYNACORD is able to draw today.Early results included the KI cinemaamplifier with its output of 25 watts.The devices of the company, whichin the meantime had moved toLandau and by then boasted astaff of four employees, still borethe brand name ‘Dynaphon’.From 1948 onwards, mixing andportable amplifiers bearing thename DYNACORD were beingsold to an ever expanding circleof customers. Within a few years,the rapidly growing company hadbecome one of the leading enterprisesin the still young audiotechnology industry. Already in1954, the manual workshop havegiven way to industrial productionas the product portfolio continued toexpand. The high-caliber, pioneeringand often visionary products havebeen presented ever since at allimportant international trade fairsand marketed successfully throughoutthe world. To make it possible tosatisfy the enormous demand,DYNACORD moved to Straubing in1958. The workforce, which at thattime numbered 80 employees, continuedto expand rapidly. Severaltimes, the production facility wasrenovated or expanded.Finally, in 1986 a new plant wasopened in which more than 500employees now develop, produceand dispatch the company’s productsto all corners of the globe.5

P 64 DIGITAL AUDIO MATRIX MANAGERP 64 Digital Audio Matrix ManagerWITH IRIS-NET SOFTWARE APPLICATIONThe P 64 Digital Audio Matrix Manager is a modular,networkable and freely configurable audio systemcontroller that allows designing complete systemsolutions.In the DSP, any structures with up to 32 audio channelsare freely configurable. This is possible by the widevariety of different DSP blocks available, such as mixer,matrix, dynamics, crossover, EQ, and even FIR filters.The processing power of the DSP can be furtherincreased with extension modules. Freely expanding thehardware configuration as well is possible throughfour module slots located on the rear of the P 64.Theses slots can be equipped with 8-channel digitalor analog input or output boards; even a specialmicrophone input card is available.14

P 64 DIGITAL AUDIO MATRIX MANAGERSeveral P 64s can be interconnected via a CobraNetnetwork, which allows operation and supervision ofeven the largest decentralized audio systems. Integratedcontrol and logic functions ensure that complex operationscan be carried out without problem.It is for example possible to link various parameters to eachother in a Task Engine using logic and arithmetic functionsand apply the results to an arbitrary number of otherparameters. This also provides the possibility fortime-controlled operations.Faults in and breakdown of the P 64 Manager itselfand all devices integrated in the system are detectedautomatically. An according message can be outputvia control contacts, other interfaces or displayed onthe PC screen.15

FIR), mixer, matrix/router,dynamics, crossover, delays,loudspeaker-controller and signalgenerators, determine the processingpower needed.The modular concept of the P 64makes it possible to adjust theconfiguration in an ideal fashion tomeet the requirements imposed.With each of the 8-channel inputor output modules, the processingpower of the P 64 is raised by afurther 100 MIPS (million instructionsper second). With the DSP-1expansion card, the processing poweris increased by a further 300 MIPS.A wide variety of applications in thefixed installation or concert soundfields can therefore be realized in thehighest audio quality with greatflexibility.DSP-1The DSP-1 is a DSP extension modulefor use in a DYNACORD P 64.The module is armed with additionalDSPs to expand the signal processingcapacity as well as RAM storagebanks for the realization of longerdelay times or additional delaylines.ADDITIONAL CHARACTERISTICS:• 1300 MIPS processingcapacity – doubling theDSP processing power• 2 RAM banks (512K x 24 bits)– for additional delaylines up to 21.8 sec.• 48-bit signal processing– double-precision DSP algorithms.• Automatic configuration – reportingin IRIS-Net when new module wasloaded or module was removed.P 64–1500 (SET)With the P 64-1500, the internalexpansion slot gets equipped witha DSP-2 module which is part of theset.As a result of the 3 additional dualcoreprocessors on the DSP-2 module,the signal processing capacity isconsiderably increased. At thesame time, applications requiringlong delay times (e.g. for delaylines) benefit from the additionalRAM. The P 64-1500 is thereforeoutstandingly well suited to complextasks and the implementation ofprocessor-intensive FIR algorithms.With its processing power of 1500MIPS (with input / output modulesmax. 1900 MIPS), the P 64-1500is currently the most powerful proaudio processor.DSP-2DSP expansion module formingpart of the P 64-1500 Set.The module is armed with additionalDSPs to expand the signal processingcapacity as well as RAM storagebanks for the realization of longerdelay times or additional delaylines.ADDITIONAL CHARACTERISTICS:• 1200 MIPS processing capacity• 3 RAM banks (512K x 24 bits)– for additional delaylines up to 32.7 sec• 48-bit signal processing– double-precision DSP algorithms• Automatic configuration – reportingin IRIS-Net when new module wasloaded or module was removed17

P 64 AND IRIS-NETP 64 and IRIS-NetHIGH END LIVE APPLICATIONS18

IRIS-NETIRIS-NetSOFTWAREThe P 64 Manager runs underIRIS-Net, which is by far morethan a common configurationsoftware application, becauseIRIS-Net is also capable ofcontrolling and supervising allcompatible components.IRIS-Net integrates all devicesof the manufacturer that can beconfigured and/or remotely controlledvia PC in a comprehensiveaudio system: in 2006 DYNACORDintroduced a new series of IRIS-Netcompatibleamplifiers – the PowerH– followed by the P 64 MatrixManager and now the DSP 600. Ourcurrent product range is completedthrough the integration of theDYNACORD DCS System whichoffers extended control and monitoringfunctionality.Easy and comfortable operation isguaranteed through PWS programmablewall stations and TPItouch panels. The universality andflexibility of the IRIS-Net softwareapplication is one of the majorstrengths of the DYNACORD DigitalAudio System – the complete audiosystem including all its componentscan be configured, controlled, andmonitored using one single softwareapplication. IRIS-Net supportsEthernet, CobraNet, CAN-Bus, USBand, because of its open architecture,IRIS-Net is ready for future implementations,such as e.g. Audinate Dante.IRIS-Net is also suitable for therealization of security-relevant systems– even stadiums or airports – wherelife safety levels not only requirethe complete monitoring and surveillanceof the connected devicesthemselves but also of connectioncables, interfaces, and connectedloudspeaker systems.The “System Check” in particularis one distinctive feature that runsa precise impedance sweep of allloudspeakers in the system by thepush of a button. Besides detectingfailure of complete loudspeakersystems, this also ensures thatdamage of a single speaker chassisis being detected. System status isqueried continuously, fault conditionsare recognized and reportedand a protocol lists incidents bydate and time.Operation of the DYNACORD DigitalAudio System using IRIS-Net takesplace in real-time via wall stations,touch panels, PC or even mediacontrol units. The change of a parameterat one of the control unitsis simultaneously indicated at allother control units.Typical applications are for example:hotels, gymnasiums and multipurposefacilities, cruise liners orsports arenas, but also live-concerts,clubs or open-air festivals.19

POWERH SERIESThe PowerH power amp series represents a further milestone in the 60-yearpro audio tradition of DYNACORD.DYNACORD has long been established worldwide as a manufacturer ofprofessional high-performance amplifiers and by virtue of numerousinnovations and the downright legendary reliability of its products hassecured for itself a firm place in the elite segment. No small contributionto this success has been made by the firm’s largest OEM customer: itssister company, Electro-Voice.PowerH Series· H 2500· H 5000For years now, countless large and very large sound reinforcementsystems installed or on tour throughout the world have been relying onDYNACORD / Electro-Voice power amps. Thousands of amplifiers madeby DYNACORD have been deployed on every continent and performedwith distinction at many of the truly major productions of recent years.33

POWERH SERIESPowerH SeriesHI-END REMOTE CONTROLLABLE POWER AMPLIFIERSThe demands placed on modernpower amplifiers are enormous:maximum output, minimumweight, the highest possibledegree of efficiency, outstandingaudio characteristics, absolutereliability, remote supervisionand remote control as well asnetwork capability.To realize stable outputs of 2500 W /4 Ω and 3500 W / 2 Ω per channel,power amplifiers must be capableof making available peak outputvoltages of 180 V to 200 V. Thisrequirement limits the number oftopologies meriting considerationto two concepts only: Class D andDYNACORD’s Linear GroundedBridge Class H. Linear Push-Pullconcepts with Class H topologyare proven solutions for powerlevels up to 1500 W / 4 Ω.This is the approach adopted bymany DYNACORD power amplifiers.The limitation of the Class H push-pullapproach is the 250 V specificationof typical audio power transistorsand their second breakdownrestrictions. Even exceeding thespecified peak voltage or thesecond breakdown limit for shortperiods leads directly to a failureof the power transistors and thepower amplifier. The use of exotic350 V-specified transistors affordsno reliable solution in view of theirsecond breakdown behaviour,their performance and also theiravailability.Higher power classes requiredifferent solutions! DYNACORD‘slinear Grounded Bridge designs(e.g. L2400 / P3000) have provedextremely reliable over many yearsas well as outstanding in terms34

POWERH SERIESof audio performance. One ofthe key advantages of GroundedBridge solutions is the considerablereduction in ‚voltage stress‘ for thepower transistors. This permitsthe design of high-powered poweramplifiers with peak output voltagesin excess even of 200 V.A logical step in the direction oflowering power dissipation whilstat the same time increasing theoutput power was the developmentof a linear Grounded Bridge topologyusing Class H technology witha multi-stage switching ‚floating‘ powersupply. The use of an extremelystable switching power supplymakes a decisive contribution tothe very low weight of these poweramplifiers: 7 kW packed into a devicea mere 2 rack units in height andweighing less than 15 kg!PowerH power amplifiers are readyfor integration into IRIS-Net-basedaudio systems and networks.Remote control modules (e.g. theRCM-26) that can be retrofittedoffer complete system supervisionand remote control combined withdigital controller functions.FEATURES• stable, very high power output• very high efficiency• very lightweight• multi-stage Grounded BridgeClass H topology• ‚floating‘ switching power supply• large liquid crystal display• integrated micro-controllerfor internal control• remote control module can beretrofitted for integration into theIRIS-Net bringing supervision,remote control, digital controllerfunctions and digital audio inputs35

POWERH SERIES“ALL IN ALL, A PERFECT COMBINATION, IN WHICH IT IS EVIDENT FROMEVERY DETAIL THAT THE DEVELOPERS KNEW EXACTLY WHAT A HIGH-ENDPOWER AMPLIFIER FOR THE PROFESSIONAL TOURING AND INSTALLATIONMARKET NEEDS.” Test in `Production Partner` 10/2007The power amplifiers of thePowerH series represent amilestone in the design andproduction of high-performancepower amplifiers.Their innovative multi-stage GroundedBridge Class H topology with itsfloating switching power supplyoffers very high and stable outputpower, very high efficiency, anextremely high level of audioperformance and extremely lowweight.They are therefore the ideal driversfor professional touring and highendconcert sound, as well as prosound, applications. Through theuse of IRIS-Net-compatible remotecontrol modules, they also offerextensive remote supervision andcontrol functions as well as a universaltwo-channel digital controllerincluding ultra-precise FIR filteringand digital algorithms to protectthe loudspeakers. DYNACORD poweramplifiers are known for theirabsolute reliability under the mostarduous of conditions on the road.Naturally this is also true of thePowerH models.In addition to the legendary manufacturingquality that comes withthe ‚Made in Germany‘ label, thecomprehensive set of protectivecircuits plays an important rolehere: an integrated micro-controllercoordinates tried-and-testedprotections against short-circuit,HF or DC at the output, back EMF,overheating and open-circuit operation,the power-up current limitationand dynamic audio limiters as wellas making additional new and highlyintelligent protective functionspossible: for example, the temperaturein the power amplifiers ismonitored at no fewer than six differentpoints and the front-to-rearventilator governed accordingly.Under abnormal thermal ‚worstcase‘ conditions, the CPU activatesa voltage limiter or gain reductiondepending upon the requirements ofthe situation, so as to obviate theneed for a thermal shutdown ofthe power amplifiers. All correctivemeasures are indicated by LEDs onthe front panel and detailed clearlyon the liquid crystal display. Inaddition, a report is created makingit possible to enquire later as to allsuch ‚interventions‘, each of whichis time-stamped.The mains voltage is monitoredand displayed continuously, withthe devices adapting automaticallyto 230 V, for example, or 120 V. Atthe same time, the mains currentconsumption is also monitoredand displayed. The trip value of theautomatic circuit breakers can beset by the user via the display ofthe power amplifier to prevent thecircuit breakers tripping. Any short-36

POWERH SERIEScircuits at the output of the poweramplifier are detected early on,even at low levels. The protectivecircuit is activated and a report onthe fault in question appears simultaneouslyon the front display. In theevent of excessive high-frequencyoverload, there is an automatic levelreduction to protect the poweramplifier itself and also the loudspeakercomponents connected.The large, background-lit liquidcrystal display delivers comprehensivestatus information, error reportsand measurements as well asallowing you to control the basicsettings and (with the IRIS-Netmodule integrated) select presetsas well.In addition to extreme reliabilityand forward-looking operatingsecurity, the PowerH power amplifiersare impressive for their outstandingaudio performance. The THD,intermodulation distortion (IMD-SMPTE) and dynamic intermodulation(DIM) are well below 0.05 % andtherefore well below the limit ofaudibility. All the components ofthe switching power supply are sosafely dimensioned that they arecapable of delivering the maximumpeak output current of 70 A continuously(H 5000), thereby allowingthe power amplifier to operateas a stable voltage source evenwith extremely low loads. PowerHpower amplifiers therefore havea significant amount of headroomat their disposal, which results insuperlative dynamics even withlow loads.PowerH power amplifiers leavenothing to be desired in terms ofconnectivity. For the inputs, XLRIN / parallel OUT sockets are providedalong with additional Phoenixconnectors. The gain is switchablebetween 32 dB, 35 dB and inputsensitivity 0 dBu. In addition, thereare switches for Bridged Mode andParallel / Dual as well, naturally, asa Ground Lift switch.A latching PowerCon connectoris provided for the mains powerline, which prevents the plugbeing yanked out accidentally. Thepower outputs are implementedas Speakon sockets. The signal ofOutput B is additionally available onpins ±2 of Output A, so that with4-pin wiring a two-way system canbe driven. Parallel to these, additionalbinding posts are provided.

RCM-26RCM-26DIGITAL CONTROLLER MODUL FOR PowerHFIR-TUNEThe RCM-26 is a dual-channel digital controllermodule for live sound, PA and fixed installation. Itoffers all conventional signal processing functionssuch as parametric equalizers, crossovers, delays,compressors and limiters.It also makes available linear phase FIR filters, zero-latencyFIR filters and digital loudspeaker protection algorithmsto permit the dynamic range of the amplifier to beexploited to the full. In addition to the electronicallybalanced analogue inputs of the power amplifier, digitalinputs in AES3 (AES / EBU) format are on board.Using the CAN bus, networks of up to 250 power amplifierscan be realized. Additional interfaces include theRS-232 interface for media control and the Control Portwith freely-programmable control inputs and outputs(GPIO). Despite its compact dimensions, the RCM-26is unmatched in terms of its capabilities and audioperformance. The IRIS-Net Remote Control ModuleRCM-26 extends the functionality of PowerH poweramplifiers by providing:• Remote Control• AES3 (AES / EBU) digital inputs• digital signal processing including FIR-TUNE• loudspeaker protection algorithms• system integration and networking• linear 24-bit AD / DA converters,sigma-delta, 128 x oversampling• dynamic range > 116 dB• 48 kHz sample rate, 96 kHz optional• THD+N < 0.005 %• 2 DSPs 150 MHz / 300 MIPS computational power• 48-bit double-precision algorithms39

IRIS-NETSUPERVISION AND DIAGNOSISThe RCM-26 transmits all relevant amplifier data tothe IRIS-Net user interface, supervising the operatingstatus of the power amplifiers, the temperature in thepower blocks and in the power supply, voltages andcurrents at the outputs, all protections, the mainsvoltage and current consumption, pilot tone and networkstatus.The impedance measurement with a 20 Hz to 20 kHzsine wave sweep and the comparison with the storedreference data make it possible to diagnose with precisionthe condition of the connected loudspeakers andeven of their individual components and cable connections.Problems are therefore detected early and thesystem is able to respond in good time.It is even easy to examine the state of loudspeakersthat are difficult to access, such as those in stadiumsor large entertainment venues. The System Checkfunction allows you to measure comprehensively,and conduct a full examination of, a very large audiosystem at the push of a button.Even in live performance, the connected load is monitoredcontinuously. Any undershooting (short-circuit)or overshooting (interruption) of the set tolerancelimits is automatically detected and reported immediately.FIR-TUNEAlthough FIR filters require a massive amount of processingand are complex, they are realized in the RCM-26 inaddition to the classical filtering and signal processingfunctions. Both linear-phase FIR filters and ‚zero latency‘FIR filters, which add no further delay to the time signalstake to pass through the device, are available.Users can create their own linear phase ‚brick-wallX-over‘ and edit them in real time. For DYNACORDloudspeaker cabinets and systems, factory presets areavailable with linear phase ‚brick-wall‘ FIR crossovers.40

IRIS-NETThese provide users wishing to tune the system themselveswith a completely linearized frequency and phase responseupon which to build.SYSTEM FREQUENCY RESPONSE IN DISPLAYFor DYNACORD loudspeaker cabinets, measurementsof the frequency and phase response are already providedin the IRIS-Net.This data together with the filter, crossover and delaysettings conducted in the RCM-26 can be displayedand taken into account by IRIS-Net. The superpositionshows the resulting accoustical frequency response ofthe loudspeaker cabinet.REMOTE FUNCTIONSRemote control of the power amplifier under IRIS-Netprovides Power On / Standby switching and theprogramming of power-up sequences for the poweramplifiers as well as level settings and the muting ofindividual channels or channel groups. In the RCM-26,all parameters can be controlled in real time as wellas stored in user memories, from which they can beretrieved and reloaded subsequently.DSP FUNCTIONS• X-over: Linkwitz-Riley, Butterworth, Bessel• FIR Filters: zero latencyprocessing, linear phase X-over• Master EQ: 6 filters per channel; PEQ,lo-shelf, hi-shelf, hi-pass, lo-pass selectable• Channel EQ: 6 filters per channel; PEQ, lo-shelf,hi-shelf, hi-pass, lo-pass, all-pass selectable• Master delay : 2 ms - 2000 ms per channel• Channel delay: speaker alignment• Dynamics: peak anticipation limiter per channel• Protection: TEMP limiter forthermal loudspeaker protection• Others: input routing, level, mute,polarity, sine and noise generators, VU meterIRIS-Net is downloadable free of charge in the memberarea of the DYNACORD website: www.dynacord.com41

Theunique combination of Class D poweramplifier blocks and synchronizedswitching power supplies offers tothis date unmatched power densitycombined with excellent audio performance.UNIQUE FLEXIBILITYTHROUGH VLDThe ability to switch individually themode of each power amp channelhelps the DSA multi-channel poweramplifiers to achieve a degree offlexibility never before possible. Inlow impedance operation (2 Ω, 4 Ω,8 Ω), each channel can drive up tofour 8-ohm loudspeaker cabinets.The output channels can also bepaired in bridged mode. Dependingupon the application, each channelcan be switched individually evenin high-impedance mode (HZ) inorder to drive 70 Vrms or 100 Vrmsloudspeaker lines directly withoutan output transformer (DirectDrive). The power output by theDSA multi-channel power amplifiersis (along with its thermal capacity)limited only by their maximum outputvoltage and maximum outputcurrent, which means they can driveany load between 2 and 10 ohmswith their rated maximum outputsof 500 W and 1000 W respectivelyper channel.54
