Beyerdynamic's Headzone portable headphone system allows for professional monitoring and provides headphone-based 5.1 surround sound reproduction using current DSP technology. The system also offers a patented ultrasonic headtracking system, which locates the orientation of the listener's head with respect to the source material and adjusts the audio accordingly for optimal mobility.
NHT Pro's S-80Xd DSP-corrected subwoofer features two 12in. woofers mounted back to back to eliminate unwanted vibrations and the need for cones or spikes. The subwoofer is equipped with a 500W Class D amplifier and features an outboard XdA containing the DEQX DSP processor, four amplifiers, and a power supply. It also includes RCA and XLR inputs, four powered outputs (to power either a single M-80Xd or a pair of M-60Xd monitors), and two-line and balanced outputs for adding subwoofers.

AUDIO CONTROL SYSTEM
Golan Systems' iCast 16/88 system enables control of up to 16 channels of any source, as well as 16 stereo audio channels and one voice announcement channel. The system also provides connection to up to 88 wired control units. Each unit includes volume and channel control and a headphone jack. The content can be displayed on any screen with a video input jack. Digital signage broadcasting units that would produce a text scroll to be displayed at the lower part of each screen are currently under development. The text could be broadcast from a local computer network or by an authorized person from a distance.
