Amphenol TAC-4, TAC-12

Hermaphroditic connectors
Gepco International

Amphenol TAC-4, TAC-12: Gepco has added Amphenol TAC-4 four-channel and TAC-12 twelve-channel hermaphroditic connectors. The connectors are industry standard, multi-channel formats designed to withstand use and abuse in harsh environments. As with all of the company's fiber assemblies, Amphenol assemblies are factory terminated by Gepco and feature precision, machine-polished contacts that offer UPC quality to achieve -55dB return loss specifications. This process helps to attain excellent optical clarity and alignment, reducing back reflection and minimizing insertion loss. For further transmission assurance, all assemblies are 100 percent tested and verified for consistent performance and feature premium quality connectors and components.

Airtools Voice Processor 2x

Programmable voice processor

Voice Processor 2x: This microphone processor offers a comprehensive set of voice enhancement tools. The 2x's Windows software application enables total control of all essential parameters. Once a desired sound is dialed in, all settings are saved as named presets for later recall from the front panel or remotely. Any mic can be optimized for a diverse air staff. The device has two inputs selectable as line or mic level with phantom power and four outputs. All signal processing is controllable via software. Audio inputs and outputs are accessed via rear panel XLR connectors.

Nautel NX25

AM transmitter

NX25: The NX25 offers digital pre-correction, 2.7MHz direct digital modulation and 88 percent efficiency. All NX Series transmitters are unique in their ability to add an optional HD Radio Exgine embedded signal generator card directly within the transmitter. Nautel's module-level design of the NX Series provides redundancy and enables users to interchange NX25 parts if needed with an other NX series transmitter. Nautel's Advanced User Interface is included on the NX25. This 17" color LCD screen with configurable displays includes real-time impedance measurement, instrument grade spectrum and audio analyzers, IBOC modulation analyzer, module-level monitoring and control/logging of all functions. The AUI can be controlled by touch screen or via a mouse and keyboard; users also have 100 percent remote access to the NX25 via a Web browser.

Day Sequerra M2HDSP

Modulation monitor
Day Sequerra

M2HDSP: The M2HDSP, Day Sequerra's newest modulation monitor for HD Radio employs the company's recently developed digital signal processing (DSP) architecture, first introduced in its M4DDM. The M2HDSP runs Day Sequerra's new proprietary Time Lock algorithm to automatically maintain perfect alignment of the HD Radio main program signal (MPS) analog and HD-1 digital audio. Using its selective off-air tuner, the M2HDSP measures the MPS analog and HD-1 digital audio diversity and generates a continuous stream of correction vectors to keep the analog and digital audio perfectly time and level aligned. These correction vectors are then sent via Ethernet to an HD Radio embedded exporter or compatible audio processor to provide the necessary adjustments to the analog audio delay.
