GV² Series

Advanced User Interface (AUI)

Nautel’s transmitters to place enhanced control into the hands of engineers so that they could become more efficient in their work, whether they are local to the transmitter or remote, using the award-winning AUI.

Built-in commercial grade instrumentation can mean even more savings and helps you optimize your on-air signal. Advanced control features include:

• New dynamic RDS scrolling

• Comprehensive monitoring and control to the sub-module level
• Extensive logging of all events
• SNMP support
• Email notifications

HD PowerBoost™ GEN⁴

Nautel’s award-winning HD PowerBoost™ GEN4 is a revolutionary technology that increases HD Radio^® power output while at the same time increasing efficiency, and addresses the FCC HD injection level increase ruling.

N+1: Cost Effective Automated Transmitter Backup

Nautel N+1 configurations support up to eight identical main transmitters plus a backup transmitter serving outputs of 150 watts to 40 kilowatts of solid-state power.

MPX over AES

100% digital path eliminates the noise and distortion of A/D converters and reduces potential overshoots, while ensuring full FCC mask compliance.

Unmatched Value

GV² Series transmitters include useful, time-saving capabilities:

• SHOUTcast™ and IceCast streaming input
• RDS generator
• Audio spectrum analyzer
• Powerful presets
• LD-MOS
• Optional UPS interface
• PUSHRADIO™ with scheduler and play lists
• Nautel PhoneHome™ proactive status monitoring

Affordable High Power

The GV² Series offers affordable, high-power, solid-state with outputs up to 88 kW. That means more power for digital and more power for increased IBOC injection levels.

Unlike traditional high-power solutions the GV² Series eliminates single points of failures. Your GV² can lose fans, power supplies, power amplifiers, whole power modules, even its user interface and stay on the air. Its simple air cooling also makes the GV²’s high power easy to deploy.

Transmitter-Centered Design

Traditional designs put features and display capabilities into a very expensive external exciter rather than the transmitter. If you want exciter redundancy you need to purchase two of these expensive devices and end up with two displays.

Nautel high power design puts all control functionality right inside the transmitter where it can provide the most benefit. A generous sized touch screen is provided locally and the same advanced control can be accessed anywhere on the web. GV Series transmitters also provide an additional LCD display on the control module for extra control redundancy.

By eliminating outboard exciters you save money, gain even more advanced features and acheive centralized control over all transmitter functions including the exciter(s). In fact the exciters are so cost effective that many customers buy two.

Highest Hybrid IBOC Efficiency

With the GV² Series Nautel has charted new ground for digital transmission efficiency. Traditionally, digital hybrid modes have displayed much lower efficiency compared to analog-only broadcasting. The GV² addresses the need for analog/digital hybrid efficiency as well.

A new Spectrum/Efficiency Optimizer dynamically optimizes digital transmission parameters to achieve optimum spectral performance and efficiency. Digital efficiencies have improved by up to 15%. High digital efficiency can result in tens of thousands of dollars savings over the life of your transmitter.

Designed for Digital

Whether you intend to broadcast digitally now or in the future your GV² Series will be ready. While most transmitter designs have been adapted to address the digital broadcasting era, Nautel engineers started fresh to ensure the GV Series would offer the best possible digital radio performance.

The transmitter supports adaptive pre-correction, MPX over AES, and even accepts I&Q directly to permit a plug-in HD Radio^® Exgine.

To meet the toughest demands for digital power and coverage, Nautel invented HD PowerBoost™ GEN4 and was the first to offer Asymmetrical sidebands. You’ll ensure optimal performance by utilizing the built-in MER instrumentation and Spectrum/Efficiency Optimizer.

Ease of Ownership

Like every Nautel ever built the GV² Series incorporates solid state components in rugged, highly redundant, hot swap architecture. Common modules across the family minimize spares requirements.

Compact footprints, published parts lists and screw driver replaceable power FETS make living with your GV transmitter easy for years to come.

HD Radio^® MER Instrumentation

Nautel provides instrumentation for real-time measurement of MER (Modulation Error Ratio). The measurements follow the NRSC standards for measurement, and require no external equipment.

Real-time MER lets you diagnose issues such as interference with the MP3 carriers near the analog signal due to FM analog signal over-modulation.

Increased HD Power

No one else builds single-cabinet, solid-state transmitters with power outputs of 6 kW – 30 kW in -14 dB hybrid mode and 5 kW – 21 kW for -10 dB.

Nautel includes its award-winning asymmetrical HD Radio^® transmission capability FREE with all new HD-equipped transmitters.

Site Control

Using existing parallel inputs and outputs, the GV Series offers built-in, fully integrated monitoring and control instrumentation for site-related equipment via Nautel’s award-winning AUI; e.g. air conditioning and generator status. The AUI can also notify broadcasters via email if any monitored parameters transition to their fault state.

Using the AUI’s intuitive Site Control menu, users can also develop more complex logical expressions involving pre-existing or custom remote inputs and outputs. These expressions can drive physical remote outputs to control the operational state of other site equipment; e.g. to open a building vent if the air-conditioner fails. Delays and latching functions are also available for each expression, along with visibility of the current state, notifications and logging via the AUI.

Radio Air-Chain

Nautel and Telos Alliance are bringing exciting, innovative approaches to the radio air-chain. The collaborative effort by the two companies paves the way for easier and more flexible digital radio deployments via virtualized audio processing and software-based Gen4 HD Radio importer/exporter.

Single Frequency Network (SFN)

A Single Frequency Network (SFN) is a network where multiple transmitters broadcast the same signal on a single frequency, allowing radio broadcasters to expand their coverage. Nautel offers an efficient SFN solution by utilizing SPANFM (FM Head-end) to synchronously transport content to multiple SYNCFMs (FM decoders) strategically positioned at each radio transmitter within the SFN network.
