MOREIP AUDIOSTREAMINGINPUTAXIA LIVEWIRE IP AUDIO SUPPORTADVANCED INPUTOPTIONSIP audio transport is becoming theindustry norm for connecting studioequipment. Transmitters too canbenefit from the move to IP. Nautelwas the first manufacturer to offer anIP audio input in addition to AES andtraditional mono and compositeinputs. Nautel’s transmitters are thefirst to support the Axia Livewireprotocol. Now broadcasters canconnect their Livewire networksdirectly to a Nautel transmitter toachieve an all-digital transmissionpath from studio to transmitterwithout intermediary connections orD/A conversions.SHOUTcast and IceCast streaminginput provides even more audio sourceoptions. Consider that over 40,000stations worldwide stream their audioto the Internet using SHOUTcastand IceCast. The GV Series gives youadded flexibility by supporting thesestreaming services as a transmitterplayout option. Streaming supportopens up many new possibilities forbroadcasters including the option tostay on-air by transmitting the stationsSHOUTcast stream in the event of afailed STL.

MORE CONTROLAsymmetricalSidebandsREAL TIME BUILT-IN INSTRUMENTATION100% REMOTE ACCESSGV Series transmitters include built-in instrumentation thatwould cost tens of thousands of dollars if purchased separately.No matter where you are, you’re only moments away fromensuring your GV Series transmitter is operating optimally.Open a web browser, enter your transmitter’s IP address andpassword and you’re connected. 100% of the local GV Seriesdisplay functionality is available on any web-enabled device.SNMP SUPPORTGV Series transmitters support Simple Network ManagementProtocol (SNMP), a network protocol that allows networkmanagement systems to monitor GV transmitters.NEW OSCILLOSCOPE INSTRUMENTATIONThe GV Series now includes Oscilloscope functionality whichallows for comparison of the forward and reverse pathsignals and for monitoring the audio input waveform in thetime domain.

GVSeries3.5 kW – 88 kW Digital/Analog FM Digital Efficient Intelligent Refined“The most intelligenttransmitters ever designed”The Next Generation TransmitterThe new GV Series represents the culmination of years ofNautel transmission innovation. These new designs incorporateeverything you have come to expect from a modern Nauteldigital/analog transmitter. Engineered using Nautel’s fieldproven binary combined high-power architecture, they offerthe industry’s highest digital power outputs, commercialgrade instrumentation, advanced intelligent features andaward winning control via Nautel’s AUI. All of this capabilityis packaged in thoughtful uncluttered designs that allow easyaccess for maintenance.In the last 5 years broadcasters worldwide have installedalmost 2,000 of these reliable systems that are based onNautel’s high power architecture and serve the globe’s largestand most successful stations. The GV Series extends thatlegacy and charts new territory with even more digital power,new achievements in digital efficiency and significant newinstrumentation and functionality.

innovative EFFICIENT DESIGNProven ArchitectureA key element of the GV’s proven architecture is the powermodule. The GV power module integrates the cooling systems,combiners and amplifiers into a compact vertically orientedmodule that is easy to handle and service. It consists of 4amplifiers, each capable of providing 750 Watts, for 2500Watts nominal power and 3000 Watts maximum power permodule. The module provides a single RF input, a single RFoutput, and allows for optimal cooling and vertical air flow.The module is common among all GV family members forsimple spares planning.Integral Exciter for OutstandingFM PerformanceThe GV Series utilizes the most advanced FM exciter availabletoday. Direct-to-channel digital modulation at more than 600MSPS eliminates microphonics and spurious outputs. Considerthese additional class leading capabilities: Next-generation adaptive pre-correction Combiner equalization Spectrum analysis Redundant digital and analog audio inputs 100% digital setup: no potentiometers Flexible RDS/RBDS encoder and SCA encodersThe GV Series even has the ability to correct for group delay in amulti-station combiner system.Transmitter Centered DesignGV Series Innovation New Spectrum/Efficiency Optimizer New site control functionality via AUI Field proven architecture Award winning control Highest HD Power outputs Top IBOC efficiency Low mains operation down to 90V New oscilloscope instrumentationTraditional designs put features and display capabilities intoa very expensive external exciter rather than the transmitter.If you want exciter redundancy you need to purchase two ofthese expensive devices and end up with two displays.In a Nautel high power design all control functionality isconsolidated right inside the transmitter where it can providethe most benefit. A generous sized touch screen is providedlocally and the same advanced control can be accessedanywhere on the web. GV Series transmitters also provide anadditional LCD display on the control module for extra controlredundancy.By eliminating outboard exciters you save money, gain evenmore advanced features and acheive centralized control over alltransmitter functions including the exciter(s). In fact the excitersare so cost effective that many customers buy two.

D esigned for Di g i talBuilt for HD Radio BroadcastingTMThe GV Series and Nautel’s integrateddigital solutions make your move toHD Radio broadcasting easier andmore economical than ever. Innovativedigital components provide a complete studio and transmitter sitesolution. Gain the full benefits of HD Radio technology includingcrystal clear programming, four channels on one frequency, songtagging, and the delivery of advanced Program Service Data.Whether you intend to broadcast digitally now or in the futureyour GV Series will be ready.Rugged HD Radio ComponentsTo get started with HD Radio broadcasting just insert Nautel’soptional Exgine card into the GV chassis and deploy anExporter Plus at your studio site. In this configuration GV Seriestransmitters allow the simultaneous transmission of an analogprogram and a premium quality digital format. The NautelExporter Plus codes the main program audio stream for digitalbroadcast.Additional digital channels can be added by deploying an optionalNautel Importer Plus and appropriate iBiquity Corporationlicenses. The Nautel Importer Plus codes the secondary programand data services of an IBOC transmission including digitalchannels two to four and passes its output to an Exporter. Aconvenient user interface permits the selection of IBOC servicemodes and partitioning of IBOC signal bandwidth for a variety ofaudio multicasting. Both the Importer Plus and Exporter Plus are1U rack mount 100% solid state devices that provide outstandingreliability.Nautel Digital Innovation: Advanced HDavailable TODAY Industry’s highestdigital TPO Class Leading IBOCefficiency HD PowerBoost crestreduction HD Spectrum/Efficiency Optimizer MER instrumentation Asymmetricalsidebands Spectrum analyzer Constellation view HD Reliable transportHighest IBOC efficiencyWith the GV series Nautel has charted new ground for digitaltransmission efficiency. Traditionally, digital hybrid modes havedisplayed much lower efficiency compared to analog-onlybroadcasting. The GV addresses the need for analog/digitalhybrid efficiency as well. A new Spectrum/Efficiency Optimizerdynamically optimizes digital transmission parameters to achieveoptimum spectral performance and efficiency. Digital efficiencieshave improved by up to 15%. High digital efficiency can resultin tens of thousands of dollars savings over the life of yourtransmitter.Highest Hybrid IBOC Efficiency70%at -20 dB60%at -14 dB55%at -10 dBUnique MER instrumentationExporter Plus (top) and Importer Plus (bottom)Outstanding -14dB/-10dB performanceThe GV Series transmitters utilize Nautel’s HD PowerBoost , aunique patented technique for optimizing IBOC peak to averagepower ratios. In a single cabinet Nautel GV transmitters canprovide up to 37 kW of Analog power with a -14 dB injectionlevel and up to 27 kW with -10 dB injection. Even more power isavailable with the new dual cabinet GV60 and GV80.Asymmetrical SidebandsFor many stations, adjacent channel issues may prevent the use ofincreased IBOC injection levels on both sidebands. Broadcastershave the option to increase only one sideband while leaving theother at levels that do not cause interference with adjacent stations.This approach ensures maximum digital signal coverage.Nautel now provides new instrumentation which allows real-timemeasurement of MER (Modulation error ratio). The measurementsfollow the new NRSC standards for measurement, and require noexternal equipment.Real-time MER provides the ability to diagnose issues such asinterference with the MP3 carriers near the analog signal due toFM analog signal over-modulation.
