Audio processor
The DSPX-AM includes a wideband window-gated AGC, a four-band window-gated AGC and a four-band limiter followed by an oversampled distortion-controlled clipper. A separate look-ahead final limiter allows simultaneous full 20kHz processing for digital radio. Like its little brother, the DSPXmini-AM, it also features adjustable low-pass filtering to accommodate all AM standards, high frequency equalization, asymmetrical clipping, low frequency transmitter tilt compensation and a tone generator to facilitate easy installation and adjustment. A range of factory presets were designed to produce loud and intelligible sound for talk radio as well as achieve the best fidelity on music formats. The DSPX-AM is a 1RU processor with front-panel LED metering that is also remote controllable via TCP/IP or direct serial connection.

XLR in-line RF iso transformer
XLR-ISO is a new product for inline matching transformers. It is an XLR female 0dBm at 600 ohm to XLR male 600 ohm line level matching transformer in a shielded case. It features a compact transformer with XLR male and female ends. The shield is lifted from input to output. It removes hum and passes phantom power to condenser microphones.

Electronics resource
This instructional book introduces electrical principles and technology through examples rather than theory – enabling readers to develop a sound understanding of the principles needed by technicians in fields such as electrical engineering, electronics and telecommunications. No previous background in engineering is assumed, making this an ideal text for vocational courses and introductory courses for undergraduates.

Automatic PPM recovery
The PPM Assurance protects ratings and reduces overhead by constantly monitoring all PPM encoders and providing automatic encoder toggling. E-mail alerts and exception reporting keep stakeholders up to date. It is a complete automatic recovery system. In addition to providing reliable backup encoder activation, the PPM Assurance monitor establishes direct data connectivity to the Arbitron equipment to verify code accuracy. And because loss of audio means lost PPM credit, built-in silence sensing enables swift program recovery. The PPM Assurance also won a Radio magazine Pick Hit award at the 2009 NAB Show.

300W FM transmitter
DCE300 is a state-of-the-art FM radio transmitter designed to be the core of every radio station. The improved stereo encoder uses DSP technology with over sampling to ensure performance with low distortion, accurate channel separation and stable pilot tone. An external MPX generator and external RDS/SCA generator or audio processor can be connected to the MPX IN BNC connector to bypass all internal audio chains.

Low-power FM transmitters
The VS Series of low power FM transmitters – using only 2, 3 or 4RU including the exciter – brings Nautel's transmission performance to broadcasters operating at 300, 1000 or 2500W. In addition to the products' rugged engineering, the Nautel VS Series is the first in the industry to incorporate Internet audio I/O and Axia Livewire support in radio transmitters. Customers using the Axia Livewire protocol will be able to connect their livewire networks directly to a VS Series transmitter with a single RJ-45 cable; no intermediary connections or D/A conversions will be needed.

RF amplifier
The Pre-Amplifier will provide signal amplification from an antenna before the signal is received by the AEA VIA Echo, which has a primary purpose of being a vector impedance analyzer for testing and tuning antenna systems. When the spectrum analyzer was added, the Echo had a less-than-desired input sensitivity. The solution was a pre-amplifier that could work from the Echo's internal NiMH batteries or from ac wall power via our power adapter. The pre-amplifiers have nominal 44dB amplification. This results in the Echo's spectrum analyzer having a nominal -125dBm noise floor.

Spectrum analyzer
The Signal Hawk SH-36S-PC analyzes the radio frequency spectrum, measures intended and interfering signals, and allows setup of parameters such as frequency and amplitude markers. It displays signal amplitude versus frequency and saves traces on a PC. It is fast, accurate and sensitive (-135dBm noise floor) with the same spectrum analyzer functionality as the Signal Hawk handheld and rack-mount units. It is built in FCC compliance masks, has a waterfall display and a sophisticated spectrum analysis software package is included with the product. The Signal Hawk also received a Radio magazine Pick Hit award at the 2009 NAB Show.

Audio test application
High Speed Tester (HST) is a fast, accurate and easy-to-operate audio test application for high speed production test or testing transmission quality across a broadcast network. HST tests output level, frequency response, interchannel phase, distortion, noise in the presence of signal, crosstalk and DC offset against user-defined limits in just 1.5 seconds. The simplified user interface is optimized for high volume testing with clear pass/fail results and user instructions.

Acoustics analyzer
Auralex Acoustics is now offering an easy-to-display retail kit that complements the company’s Room Analysis Plus program for off-site analysis. The new in-store Room Analysis Kit is a complete, user-friendly package that provides all the tools needed to acoustically analyze any room. Based on the company’s existing Room Analysis Plus Program, the kit includes an omni-directional measurement microphone, a USB drive featuring swept sine signals and a complete instructional guide. Users can record a sweep with the omni-directional measurement microphone in the location of the room in question. All files can be sent via e-mail, along with the included Room Analysis Plus Form, directly to Auralex for examination by its acoustical engineering staff.

Radio
The CCRadio-2 has the same familiar look and layout as previous models of the CCRadio but with even better AM Reception and the addition of the 2-meter Ham band. The boost in AM performance comes from the company's Twin-Coil ferrite AM antenna, and other improvements. After selecting a station, the CCRadio-2 evaluates the signal for several seconds and then locks in for the highest signal possible. The addition of the 2-meter Ham band may make it practical for use during an emergency.
