The Nautel AUI, which is standard in NV and NX series transmitters, allows operators to control the system either locally or remotely. All local display functionality can be accessed remotely. Nautel touts its approach to transmitter control as unique. Rather than put all of the high-level control functionality into an exciter, Nautel treats the exciter as a module and instead uses its control interface to manage the whole transmitter including its exciters. This approach, Nautel says, brings greater control and avoids burdening the user with the cost and confusion of separate controls for the transmitter and each of its exciters. Using a 17-inch touchscreen display and embedded instrumentation, along with metering and status indication plus a TCP/IP interface, the AUI is a dashboard to drive new features in Nautel’s transmitters. Screens are easy to set up and read. The AUI makes use of information-gathering features built into the transmitters. It is automated with a top-down interface; the user selects the desired mode to run and it pops up. Metering can be configured down to the level of every amplifier, which aids in troubleshooting. The AUI keeps a history of operating levels so that the user can effectively go back in time to when a fault occurred and determine the cause. A key feature is the built-in spectrum analyzer. While other manufacturers have added spectrum analyzer functionality to their exciters, Nautel says, it uses the spectrum analyzer to cover the entire transmitter. This is a valuable addition to the unit’s system monitoring and control. The AUI also offers a constellation view of the HD Radio signal, giving visual indication of any problems. In addition to local access, the Nautel AUI can be controlled remotely via any Internet-based device including smart phones. The user simply opens a Web browser, enters the transmitter’s IP address and is connected. All of the AUI’s display functionality is available on the browser.

NTI Extends Minirator MR-Pro Capabilities The MR-Pro audio signal generator from Neutrik Test Instruments (NTI) is delivered with more storage capacity, now 512 MB. This allows storage of 16 times more tests signals than the previous version. That should translate into up to 80 minutes of audio. Units already in the field can be upgraded by the factory. Another upgrade is firmware revision 2.10. Improvements include offering compatibility with the Apple MAC OS versions 10.4 onwards running on G4/G5 as well as on the new X86 architectures. Also, in response to customer feedback the impedance measurement of the MRPro now handles power calculations for 35 V, 140 V and 200 V voltage distribution systems, in addition to previously supported 70 V and 100 V systems. This test of the calculated apparent power simplifies the load verification in distributed loudspeaker systems. Along with firmware V2.10, a WAV file set with sinusoidal subsonic frequencies between 1 Hz and 10 Hz is available for download. Each file generates a pure, low distortion sinusoidal waveform at a fixed frequency. With this set of WAV files the MR-PRO serves as a signal stimulus for vibration sources. The MR-Pro analog audio generator provides a complete set of analog audio test signals, in addition to measuring load impedance, phantom voltage, balance and testing cables, all in a palm-sized, battery powered instrument For more information, contact NTI Americas at (503) 684-7050 or visit www. minstruments.com.
