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.

Amplifier Technology

Yamaha
yamaha.com

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.

Sound Reinforcement Technology

Nexo
nexo-sa.com

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.

Measurement System

Gold Line
gold-line.com

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.
