PAGING SYSTEM SOFTWARE
The 1RU Symetrix Integrator Series Zone Mix 760 paging and music-management system features microphone preamplification, compression, AGC, matrix mixing, feedback elimination, filters and equalization, and ambient-noise compensation for restaurants, hotels, sports bars, and nightclubs. Its new version 2.1 software integrates full support for a modular ARC-MIC built-in condenser mic and an ARC-XLR XLR-input source, and it allows each of the system's wall panels to serve as a self-contained paging station with zone groups and push-to-talk functions. The new software also provides a third-party control protocol for control over IP or the hardware's new RS-232 port, as well as the ability to create preset toggles.

The new SB2A powered 12in. subwoofer from Electro-Voice eliminates the need for external system processing and amplification. It features dual 350W amplifiers in order to drive either an external 8Ω passive subwoofer or a full-range loudspeaker. The subwoofer is easily configured with a variety of loudspeakers for use in a range of sound-reinforcement applications — including for use with the ZX1-90 loudspeaker, as a standalone PA that fits in the front seat of your car, in clusters with the SX100 and SX300 loudspeakers, or with a passive SB122 subwoofer for portable lightweight sub extension to replace bulky 15in. two-way systems. The SB2A shares the same durable injection-molded enclosure as the passive EV SB122 subwoofer. Both use the EVS12S woofer, designed from the ground up for optimized performance within this small-footprint enclosure.

The RapcoHorizon Company ltiblox laptop interface is a scaled-down, compact, mono audio version of the company's new Lti-1 stereo interface. It accepts stereo audio from portable audio devices, and it provides a mono, balanced-XLR output for input into professional mixing consoles. The unit also features volume control and a 3.5mm connector on a 3ft. cable.
VCOM multichannel software from IntraCom Systems provides wireless-intercom functionality for use in professional applications. As with the PC system, the handheld version supports as many as 200 users on channels configurable for point-to-point, group calls, and party lines. Users can talk hands-free privately or in full-duplex conference. The wireless system easily interfaces with other communication systems, does not have frequency constraints, and runs on readily available Wi-Fi and/or cellular-data-network-enabled handhelds running Windows Mobile 5.0 and higher.
The Peavey SP-series loudspeaker systems feature durable new Hammertex coverings and a newly redesigned exterior with full-front metal grilles. The new loudspeakers are engineered for optimal sound reproduction. Their enclosures feature patented, asymmetrical Quadratic Throat Waveguide technology that helps deliver pristine, precise sound; Black Widow loudspeakers with Kevlar-impregnated cones, 4in. ribbon-wire voice coils, and exclusive field-replaceable baskets; the patented Radialinear planar phase-correction system; and titanium compression drivers with ferrofluid cooling.

The Soundcraft Vi series consoles offer new features — including support for multiple stageboxes and the Vi Offline Editor, which provides the ability to set up shows and configurations offline on a PC. These configurations can then be downloaded to the desk from a USB memory drive. The software will be downloadable free from the Soundcraft website beginning in March. It can be run standalone in any location, and the file can be transferred at any time. All routing, naming, EQ, and dynamic settings can be preconfigured offline. This also provides new engineers with a superb opportunity to test out the console on their laptops before getting hands on.

The SADA-4 and SADA-6 (pictured) stereo-audio distribution amplifiers from FSR feature one input and four or six outputs, respectively. These professional-quality DAs accept balanced or unbalanced inputs and outputs, and they can be configured for stereo or mono with the flip of a switch. Built-in features include individually buffered and amplified outputs. All outputs are short-circuit-protected, and they are configurable for multiple-output arrangements. Both units are ideal companion pieces for any of the company's CVD and SVD video distribution amps. The units are manufactured using a green, lead-free process.

New 135MA and 160MA mixer/amplifiers from Crown International feature both 8Ω and constant-voltage outputs (70V and 100V), and they are easily configurable for a variety of uses — including paging, background music, on-hold music, security use, and safety/evacuation announcements. Each unit is housed in a highly compact 1/2RU chassis. The 135MA is equipped with three inputs and a 35W amplifier output, and the 160MA provides four inputs and a 60W amplifier output. Both models provide priority muting that can be voice-activated or triggered via an external switch, and both models are compatible with microphones requiring phantom power.
LCD FLATPANEL DISPLAYS
Planar Systems has introduced two commercial-grade direct-view LCDs for use in control rooms and digital-signage applications.The m40L is a 40in. flatpanel with WXGA native resolution (1366×768), and the m46L is 46in. with HD 1080p resolution (1920×1080). Other features include built-in power management and automation, an intelligent light sensor that automatically adjusts the backlight, and an optional protective front faceplate. Planar m-Series displays are specifically suited to withstand intense ambient conditions in demanding environments.
DIGITAL SIGNAGE TRANSMITTER
The Magenta Research Octet UTP/Cat-X distributive transmitter is optimized to deliver the display control and metrics desired in dynamic-signage applications. It distributes WUXGA video, stereo audio, and display-addressable control signals within a 2000ft. radius from the source, with no repeaters or booster units. The transmitter also supports DDC and the Windows Vista operating system, eight UTP outputs for signal distribution, and loop-through outputs for video, audio, and EIA-232.
