My license is only for 100 watts, but the VS300LP operates up to 330 watts, is this okay?
You set the operating Total Output Power upon initial set-up, it’s configurable from 8 to 330 watts. LPFM licenses are for 100 watts Effective Radiated Power, so you might need more than 100 watts TPO to achieve that depending on your antenna gain and coax line loss.

What is the difference between the VS300 and the VS300LP?
The VS300LP is FCC type certified for LPFM use and bears the required FCC label on the back of the transmitter. There is also one hardware difference, an AC line filter.

What is the VS300LP output connector?
The VS300LP comes standard with an N type connector.

What is the warranty and support on the transmitter?
The VS300LP comes with the standard Nautel 4 year warranty. We have technicians available 24/7. Even after the 4 year period, Nautel has never discontinued support on a product ever, you can still call a technician and order required parts, you simply have to pay for the required parts.

Does the Nautel VS300LP have internal audio processing?
Yes, the Nautel VS300LP has internal audio processing. If you want additional audio processing, Nautel also offers the Orban Inside Card (a 5-band digital processor similar to the Orban Optimod 5500). The Orban Inside Card mounts inside the VS300LP and is controlled through the Advanced User Interface (AUI). This feature provides additional processing at a fraction of the cost of a full external audio processing box.

Does the VS300LP have a remote control? What is the charge for this?
The Nautel VS Series comes with the Nautel Advanced User Interface (AUI) which is accessed over IP connection in any flash based web browser. It does not require any special software on your device, just internet connection. The AUI allows you to view meters (e.g. spectrum analyzer) and data from the transmitter, including alarms, turn off and on, make audio adjustment, set up back up audio, edit playlists and more. For more details, please check out one of the VS webinars available under the Webinars section of the website.

Importantly, there is no charge for the AUI. It comes standard, and as more features become available, users can download new software for free.

The Nautel VS Series is also equipped with industry standard GPIO ports, as well as SNMP for facilities control systems.

What audio inputs does the VS300LP accept?
The VS300LP accepts AES, Analog L/R, Composite, MPX over AES, Audio Player (IP streams/USB). Up to four audio sources may be enabled with priority levels.

Does the VS300LP accept audio IP feeds from sources other than Livewire, SHUOTCast and Icecast?
The VS300LP accepts only the Livewire, SHOUTCast and Icecast formats.

I hear a lot about the back-up audio and the USB feature, can you explain this more?
In the event of a main audio failure, for example studio transmitter link failure, the VS300LP can be set up to play an IP fed ShoutCast or Icecast stream or a playlist created and saved locally on a USB drive connected to the transmitter.

Early on in the design, Nautel realized that often it’s the STL link that is the weak link in the transmission system. Accordingly, we created multiple levels of backup audio capability with automatic switchover. These backup sources include the ability to receive a station’s web broadcast Shoutcast or Icecast streams, as well as a simple playout automation system that plays .wav or .mp3 files on an external USB storage device. Also included was the capability to change a playlist remotely via the AUI, and even to upload new content via the AUI to the USB storage device.

Soon, some customers approached us and said that they didn’t want to use the USB playout system for backup, they wanted to use it as the primary source of audio content. There is a class of customers who have many stations distributed over a wide geographic area with common programming which is currently provided by satellite. The largest single monthly expense the stations have is the cost of the satellite time. They wanted to replace the satellite with the public internet, and while the public internet isn’t terribly reliable for real-time distribution of audio, it’s very reliable for file transfer. They wanted to use the playout system in the Nautel to remotely run playlists in all the network stations, while providing new and changed content upgrades as files over the net. Since the basic functionality for this already resides in the Nautel transmitters, this was easy to accommodate.

The next step was to address the fact that some of these networks have hundreds of remote stations, and making all the playlist changes and uploading all the new content would be complex and time consuming. We realized that what was needed was an automation interface to automate the control / update process. We approached ENCO, and soon they had developed an interface for their DAD system to control multiple Nautel transmitters via IP, rather than sound cards. The system makes live changes in the remote playlists and uploads new content, and will be capable of downloading an “as-played” log from the remote transmitters and reconciling with traffic and billing and music scheduling software in the master station.

We call this system ‘PUSHRADIO™’ learn more about PUSHRADIO >>
