Xử lý phát thanh AM 235
The Model 235 incorporates all audio processing needs for AM broadcasting in a single, easy-to-use package. "Gain-riding" AGC is followed by variable low- and high-frequency EQ, 3-band compression, an asymmetrical, integrated limiter/clipper peak controller, and a low-pass function that satisfies NRSC or other "audio mask" specifications. A rear-panel RS-232 data port allows the processing presets to be programmed or updated by computer or modem; the necessary software is included.

Bộ xử lý âm thanh 261
The 261 Utility Processor provides an all-inclusive system for general audio normalization, level management and FM-airchain use. It combines the functions of gated, gain-riding AGC, dynamic range compression and independent broadband and high-frequency program peak limiting. Processing functions may be selected from the front panel separately or combined for comprehensive program audio control. The 261 features AES-digital and L/R analog inputs; digital and analog outputs are available simultaneously. Digital input sample rates are detected automatically, while multiple output sample rates can be easily selected from the front panel. Extra features like alarms and a front panel lockout switch make the 261 a complete package for broadcasters looking for comprehensive level management. 100% digital DSP architecture ensures easy setup, transparent signal path, and unobtrusive menu-driven operation.

Bộ xử lý phát thanh AM 222
The 222 was originally developed as a "post-processor" to ensure US broadcasters' compliance with FCC-mandated occupied-bandwidth regulations. It incorporates a fast, asymmetrical peak limiter, independent pre-emphasis-protection limiting, and a very sharp-cutoff low-pass filter with proprietary overshoot control. The 222 finds ready application in a wide variety of AM broadcast situations. In addition to the NRSC 10kHz cutoff for medium-wave AM broadcasting in the US, any high-frequency protection characteristic between 4.5kHz and 15kHz can readily be accommodated to meet other domestic and overseas needs. Though the 222 is intended to provide basic final limiting, a "floating platform" release characteristic yields sufficient program dynamics compression that often the unit can be run "barefoot" between the console and transmitter with good results.

71901 DAVID IV HD Radio Delay Board
The 719-01 HD Radio Delay Board is an optional drop-in accessory for our DAVID IV FM/HD Radio Broadcast Processor. It enables up to 9.999 seconds of audio delay for the Composite (MPX) and/or analog and digital program line outputs. Because there is an obligatory delay of roughly 8 seconds in the digital program encoding and decoding process present in HD Radio, the analog-FM signal must be delayed by this same amount to arrive in sync with the digital signal. This time-aligning “diversity delay,” as it is called, is enabled in the DAVID IV with this optional accessory circuit board that is simply plugged into a header strip on the main board. The delay is adjustable between zero and 9.999 seconds in one-millisecond increments, and once installed, activates new a menu adjustment, using either the front-panel jog wheel or remote PC software. Use of this accessory board requires at least Rev. 2 firmware/software in your accompanying DAVID IV FM/HD Radio Broadcast Processor.

Intraplex® HD Link™
The next generation of digital STL Our challenge: to design a studio-to-transmitter link (STL) for your most demanding 950 MHz applications — one as reliable and robust as Intraplex® T1 and IP audio links. Digital STL manages much more than audio, so installation and configuration need to be straightforward, not a science project. Data should not be optional, requiring additional boxes and complexity. Your STL should be ready, out of the box, for AM, FM and HD Radio™, as well as future multimedia applications. Earlier digital STLs were not designed for IP data transport. Adding IP data to them required optional modules and external add-ons, and many engineers working on HD Radio installations reported spending much time and money trying to eliminate glitches. Our solution: HD Link™ is designed to manage all HD Radio™ transport scenarios, regardless of where you place your importer and exporter. Its two prioritized Ethernet paths give preference to HD Radio™ data over control and other LAN/WAN data. It supports both UDP and TCP, and even handles the switching of TCP return packets over asymmetric IP paths with plug-and-play simplicity. HD Link offers RF power to spare, an integrated IP gateway with sophisticated data handling capabilities, and multiple channels of audio. The intuitive front panel and remote interfaces tap into the most complete feature set of any microwave STL, yet take less time to configure. It can even operate on both RF and IP simultaneously, and allows automatic backup of all services from one to the other. Intraplex is broadcasting’s first choice for rock-solid, full-time operation of T1 STLs. With HD Link, you can now count on the same dependable performance, superior support and long-term value for your microwave links.

Intraplex NetXpress LX™
Unprecedented Flexibility in IP Audio Transport Intraplex NetXpress LX™ IP audio multiplexer delivers a high-performance IP audio platform in a scaled down, affordable package. Supporting both unicast and multicast, and compatible with the existing NetXpress, the NetXpress LX system opens up new possibilities in IP audio network design. Existing T1/E1 Multiplexer Conversion to IP Forget about retiring perfectly good Intraplex systems when moving from T1 or E1 to IP. The new NetXpress LX IP interface module, the CM-30, can replace the network interface module in existing Intraplex T1/E1 systems, converting them to IP while keeping the existing chassis with all of its audio, voice and data cards. Intraplex Reliability When the mission is critical, broadcasters turn to Intraplex audio transport systems — the standard-bearer for dependable, great-sounding audio links for always-on applications. Built upon the technology of the original NetXpress system, but with a form factor matching that of our T1/E1 systems, the NetXpress LX multiplexer provides the reliable and robust performance demanded by studio-to-transmitter link (STL) and other fixed, full-time inter-facility applications. Available in two sizes — a 3RU frame with capacity for up to 17 application modules and a compact 1RU frame that can hold five application modules — the NetXpress LX system can also work as an “edge” device along with the NetXpress multiplexer in large, multisite networks. The NetXpress LX multiplexer provides the superior support and long-term value expected from Intraplex — broadcasting’s first choice for robust, full-time operation of IP audio, T1/E1 and 950 MHz audio and data links.
