Using Hafler's Trans*nova circuitry, TA Series amplifiers produce natural sound and realistic reproduction. The TA1100 100W amp and TA1600 150W amp both include specialized circuits to prevent damage to the amplifiers and speakers without affecting the audio signal. A thermal sensing network monitors the heat sink and transformer temperature and shuts down the amplifier to protect from excessive operating heat.

Feedback Eliminator

Architectural Acoustics

Based on a DSP engine, The Freq-Out 116 feedback eliminator uses “seek and destroy” software and 16 precision dynamic depth notch filters to help systems installers reduce feedback and improve system gain. The single rackspace unit has a front-panel interface that lets the installer access the processor's controls and operation modes. Each filter has a three-state LED for at-a-glance monitoring.

Loudspeaker System

D.A.S. Audio

D.A.S. Audio's Compact 1 self-powered loudspeaker system is a three-way, biamplified system that can be used as a full-range standalone unit or as a mid-high cabinet with bass reinforcement. The system incorporates a 1000W Class D switching amplifier, which delivers 500W to the low-frequency transducer and 300W to the mid-high section. Both channels are protected against under voltage, provide soft clipping, soft startup and a mute function.

Amplifier Technology


Yamaha has unveiled a new line of networked amplifiers that includes the PC4800N and PC9500N power amplifiers, the NHB32-C network hub bridge and the ACU16-C amplifier control unit. The PC4800N and PC9500N were designed to reproduce power linearity and low distortion. They sport switch-mode power supplies and use Yamaha's EEEngine and MOSFET technologies for low current draw and reduced heat. The ACU16-C can monitor as many as 32 PC9500N or PC4500N amps using a PC via RS-232C or USB; the NHB32-C allows 32 channels of AES/EBU to be converted to CobraNet.

Designed to be unobtrusive, the 110 series of subwoofers from Tannoy comes in passive and active versions. The 110CS corner subwoofer is a 10-inch bass unit in an optimized reflex cabinet, yielding a KT-3dB low frequency cutoff at 31 Hz in half space. A 110TB can be mounted onto a 2-by-2 foot ceiling tile space and uses an air conditioning grille to mask the unit's appearance. Sheetrock ceilings can incorporate the 110SR, which provides four seismic tether points for secure installation.

Sound Reinforcement Technology


Nexo's GEO technology controls dispersion with an acoustic mirror instead of coercive sidewalls, solving the problem of combining multiple sources without degrading coherence. The technology is targeted for use in curved vertical and horizontal line arrays. It combines three fundamental parts: the Hyperboloid Refelective Wavesource; the Directivity Phase Device (a phase plug that enables multiple woofers to couple effectively at higher frequencies as compared with direct radiating cones); and the Configurable Directivity Device, which alters the dispersion diffraction slot.

Digital Signal Processor

BSS Audio

The ProSys PS-8810 is a 2U rackspace fixed-path digital signal processor with eight inputs and 10 outputs (all of which possess dedicated processing paths comprised of EQ filters, gates, compressors, automixers and delays). Setups may be stored as presets and recalled from a PC, contact enclosure or the unit's internal events scheduler. The unit employs the IQ communication protocol from Crown and provides audio networking through Peak Audio's CobraNet.

Measurement System

Gold Line

Gold Line's measurement system for quantifying speech intelligibility uses the DSP30 analyzer platform and the STI-PA signal CD. With the signal CD playing, a single button push on the DSP30 produces STI, which is converted to the Common Intelligibility Scale (specified in the IEC standard 60849). Users can capture multiple measurements by relocating the DSP30 while the signal continues to play.

Wharfedale Pro

The Twin-12 two-way, full-range loudspeaker has a coaxial design for low-profile stage monitoring in nearfield situations when conventional systems' low- and high-frequency sources are offset too far for smooth listening and feedback isolation. Its cabinet is birch plywood covered in a two-stage, black epoxy finish and has fixing points and flying steel track for quick installation. The Twin-15 has a dynamic high-frequency driver protection circuit for progressive-dynamic limiting for short-term peaks and long-term overload conditions.
