FIXED INSTALLATION AMPS
Crown's CTs Series of six amplifiers provides a choice of direct constant voltage outputs and low impedance outputs, while increased power at every impedance improves system headroom at practical power steps. A CobraNet™ digital audio input option is available for all models including the four-channel CTs 4200 and eight-channel CTs 8200 (both shown), outfitted with new IQ and VCA features that enable remote amplifier control and/or monitoring. The units feature sophisticated protection circuitry, efficient switch mode power supply, switchable High Pass Filters, and heat-dissipating design.

MODULAR MATRIX PROCESSOR

Ashly Audio's Protea 24.24M Matrix Processor uses modular expansion cards to provide up to 24 channels of audio matrixing and processing for applications such as corporate boardrooms, restaurants, courtrooms, left/center/right theaters, or conference centers. Each input and output expansion card has an individual DSP processor for expanding the base unit's configuration (four-input/four-output) four channels at a time. With fixed path architecture and Protea System Software for programming, the 24.24M satisfies requirements for any zoned system requiring input/output matrixing with signal processing.

VIDEO DISTRIBUTION AMP

FSR Products' RGB-4 (shown) and RGB-6 video distribution amplifiers are ultra-high bandwidth 1 x 4 and 1 x 6 units designed for applications requiring superior video quality. They feature advanced sychronizing circuitry to ensure a stable video image at any resolution and signal level. The first two output channels have independent cable equalization, which allows distribution of an image to two locations over long cable runs while maintaining excellent signal integrity. RGB-4 and -6 have universal built-in power supply and are housed in a 1RU metal enclosure.

FLEXIBLE POWER AMPLIFIER

Crest Audio's CD Series power amplifiers represent a new generation of elevated-efficiency amplification, combining a linear power supply with a Class D output in a compact package. The power amps include multiple protection circuits and feature an efficient output stage allowing the power supply to handle heavy-duty cycles (up to 3,600 watts bridged on the CD-3000, shown) without compromising sonic integrity. With versatile power points and multiple inputs, the CD Series is adaptable to applications ranging from nightclubs to high school gymnasiums.

AUDIO PROCESSOR
AudioControl introduces the Diva programmable 24-bit digital audio correction system, providing fully independent, digital-domain sound processing for up to eight audio channels. The system incorporates configurable multi-channel dynamics processing, plus high-performance analog-to-digital and digital-to-analog converters for full transparency on all channels. Each channel of Diva equalization can be configured for multi-band control, with both fixed-band, constant-Q ("graphic") and parametric control. Its ample memory systems allow storage of 24 setups, each reflecting variations of EQ, inter-channel signal delay, and signal processing.

HIGH-POWER AMPLIFIER

EAW Commercial's CAZ Series of stereo amplifiers is designed for continuous duty in speech, music, paging, and sound reinforcement applications such as churches, offices, and recreation facilities. Power output of the CAZ-1400 (shown) is 1,400 watts (at 4 ohms bridged). All three models include switchable mono, stereo, or mono-bridged operating modes, as well as separate speaker outputs for channel A and channel B. A third output is provided for mono-bridged applications, and a 30 Hz subsonic filter assures low-frequency speaker protection.

FOUR-CHANNEL POWER AMP

Xantech's 100-watt, four-channel power amplifier PA4100X is designed for any application using a multi-zone pre-amp that does not require on-board IR control. An addition to the PS series, the amplifier is highly suitable as a complement to the MRC88, an eight-source, eight-zone audio and video entertainment system, to provide audio amplification for zones seven and eight at 100 watts per channel. It easily interfaces with the MRC88 controller/amplifier using a standard stereo mini-cable allowing power and muting from the MRC88.

DIGITAL SIGNAL PROCESSOR

Sabine's Graphi-Q 3100 Graphic Equalizer Series of professional digital signal processors offers hands-on digital EQ with built-in FBX automatic feedback control. Standard features include RS232 remote computer control, 70 on-board program memories, and remote switching via contact closures. GRQ3102 (shown) provides hands-on "analog-style" front panel control for every function, yet every function is digital so that every filter is shaped with no phase shifting, no drifting, and very low distortion. Graphi-Qs are designed for rigorous and continuous use in fixed and touring applications.

DUAL-CHANNEL EQUALIZER

Rane's PEQ 55 dual 5-band parametric EQ is designed for professional sound-reinforcement, fixed-installation, broadcast, and recording applications. The dual-channel PEQ 55 features five bands of fully parametric equalization, adjustable high-cut and low-cut filters, and three-band Accelerated Slope™ tone controls per channel. Front panel controls select between dual-mono 5-band, mono 10-band, and stereo linked 5- or 10-band operating modes. PEQ 55 offers analog ease of use with individual filter overload indicators and input/output level adjustment and metering.

COMMERCIAL POWER AMP
Architectural Acoustics' ICS 4200 power amplifier offers four independent, 200-watt amplifier channels in a compact, fan-cooled 2U rack-mount package. Designed for permanent installation, the ICS 4200 can supply maximum output power to both low impedance (4 and 8 ohms) and high impedance (70-volt) loads simultaneously in single-channel or two-channel pairs. For larger power output requirements, it can be configured for bridged operation. An SPS™ loudspeaker protection circuit and an integral 60 Hz high-pass filter provide protection even in severe applications.

PROFESSIONAL A/V RECEIVER
Onkyo Pro's TX-NR901P is a network-capable audio/video receiver for studio and commercial use, including both video theater applications and to drive multiple loudspeaker systems in offices, restaurants, gyms, or places of worship. The rack-mount receiver delivers 110 watts into each of seven channels. HDTV-capable and THX Select-certified, it includes a full suite of multi-channel digital audio processing capabilities, plus Net-Tune™ technology for Ethernet distributed audio, Powered Zone 2 capability, and an all-channel stereo mode for driving up to three pairs of speakers.

COMBINATION RECORDER
Marantz Professional's CDR420 CD/MP3 recorder provides a complete portable digital recording solution for events or meetings. It has a storage capacity of more than 1,400 hours and eliminates the requirement of a computer for CD recording or post-production. After the recording is complete, the CDR420 will burn any selected recordings totaling up to 45 hours of audio on a single MP3-CD. With on-board editing capabilities, the recorder makes it possible to output the audio for distribution via CD, e-mail, or website in just minutes.

HIGH-OUTPUT AMP
Yamaha's lightweight P5000S power amplifier is designed to deliver high-output power (525 watts per channel into 8-ohm loads) and efficient operation for any permanent or mobile sound reinforcement application. P Series II amplifiers (250-700 watts per channel) provide three output modes: normal Stereo Mode, Parallel Mode, and Bridged Mono Mode. Switchable, sweepable filters on each input channel (25-150 Hz) can be set as "low pass" to allow use as a subwoofer amplifier, or "high pass" when low frequencies require attenuation.

DISTRIBUTED AUDIO

Sonance's DAB1 is a four-source, six-zone distributed audio system with audio, power, and control contained in a single component. Designed to work with typical 3-wire IR devices, the system features a built-in AM/FM stereo tuner, 12 channels of audio amplification for six stereo zones, front-panel controls (source, zone, and tuner selection), an LCD display, and handheld remote. Up to four audio sources can be played simultaneously via six built-in Class A-B stereo amplifiers, which deliver up to 30 watts per channel at 8 ohms.
