Nautel VS300 – 300W FM Transmitter

Nautel logo

Summary

Nautel’s new VS Series FM transmitters are engineered to meet today’s most challenging broadcast requirements with an exceptional combination of robustness and reliability in a cost effective design. But the VS Series goes even further with industry first innovations such as IP audio I/O, Livewiretm Support and Nautel’s Advanced User Interface (AUI). Each VS transmitter has been optimized for its specific power output to maximize functionality and quality resulting in outstanding value.

Features

BIG TRANSMITTER FEATURES FOR UNMATCHED VALUE

Many transmitters in the 300 W to 2.5 kW class use an inexpensive analog exciter that is sometimes an external unit.

In the VS Series, not only did Nautel engineers integrate the exciter, they implemented a true direct-to-channel digital exciter to achieve class leading performance. That means crystal clear audio and outstanding value. A great achievement considering that digital exciters alone usually sell for over US $10,000.

The VS300 and VS1 transmitters with their built-in RDS generator, GPS input, powerful presets and -90dB SNR make for powerful and extremely cost-effective exciters.

BUILT IN INSTRUMENTATION AND CONTROL

Never before has such sophisticated control been made available in this class of transmitter.

Nautel brings its renowned Advanced User Interface (AUI) found in its high end transmitters to the VS Series. Instrumentation is included that would be valued separately at more than the cost of the transmitter. In addition a front panel LCD provides control of key functions.

Advanced control features include:

– RF and audio spectrum analyzers
– Comprehensive monitoring and control
– Extensive logging of all events
– SNMP support
– Email notifications

FULL CONTROL WHEREVER YOU ARE

Access the AUI via the internet or a direct CAT-5 cable connection. Years of interface development effort gives you immediate access to almost any parameter imaginable, whether at the transmitter site or from the comfort of your living room.

Imagine knowing in advance what parts and tools you’ll need at the transmitter site. Having that much control remotely can help you avoid trips, save time and save money.

IP AUDIO I/O

The VS Series are the first transmitters ever to implement Axia’s Livewire Studio to Transmitter Audio over IP Workflow. The result is a seamless digital IP audio path from a host of Livewire compatible devices directly into a Nautel transmitter ensuring outstanding audio purity via a CAT 5 cable.

If you stream your station on SHOUTcast you can even use it as an input should your STL fail.

USB HARD DRIVE OR MEMORY STICK AUDIO AUTOMATION

When you add this much intelligence and IP I/O to a transmitter you’ll be amazed by what you can do.

Nautel added a USB port so that you can connect megabytes of local storage. Use the storage to store content or even load up the songs and content using the VS internet connection.

Once you have audio loaded it can become part of the automated back up audio capability should all other connections fail.

NEW PLAYLIST AND AUTOMATION FUNCTIONALITY

If you think the local audio storage mentioned above sounds interesting you’ll want to learn more about Nautel PUSHRADIO™.

From your office or anywhere for that matter you can set up basic automation capabilities to playout audio or insert local content. It’s like putting part of the studio inside the transmitter.

Nautel PUSHRADIO can help satellite connected stations slash costs and provide more local content.

ORBAN INSIDE

For the first time ever, Orban’s signature processing is integrated directly into a transmitter via an economical plug-in DSP card.

At about half the cost of a standalone processor Orban Inside™ incorporates many features of Orban’s Optimod 5500 Series digital processor with 5 band processor and dual band window-gated AGC.

Utilizing the Nautel AUI, users have full control over processing functions.

Orban Inside accommodates L+R, AES/EBU, LiveWire, SHOUTcast and USB player inputs.

DIGITAL SOMEDAY OR EVEN TODAY

Maybe you have clear plans for digital broadcasting or maybe you’re not so sure but you’d like to know that your investment today keeps all of your options open.

Thanks to the optional VS digital upgrade unit – VSHD Digital Exciter – HD Radio™ broadcasting can be easily accomplished.

Staying true to the concept of big transmitter features in a low power system, Nautel even brings its award winning HD PowerBoost™ GEN4 option and free asymmetrical sideband functionality to the digital VS systems. All to help you maximize your digital coverage and all shipping today.

PROVEN RELIABILITY AND EASE OF OWNERSHIP

Every rugged and reliable VS Series transmitter is the result of years of Nautel design expertise and is crafted completely within Nautel’s North American manufacturing facilities.

Compact, value-optimized packaging, easy-to-access washable air filters, published parts lists and screw driver replaceable power FETS make living with your VS transmitter easy for years to come.
