Automatic mixing controller

Dan Dugan Sound Design

Booth N2515

Model E-1: The Model E-1 automatic mixing controller handles multiple live mics without having to continually ride individual faders. This eight-channel signal processor patches into the input insert points of an audio mixing console. It detects which mics are being used and makes fast, transparent cross-fades, freeing the mixer to focus on balance and sound quality instead of being chained to the faders. The Model E-1's voice-controlled crossfades track unscripted dialogue perfectly, eliminating cueing mistakes and late fade-ups while avoiding the choppy and distracting effects common to noise gates. Without the need for gating, a natural low-level room ambience is maintained.

Cavity backed antenna

Propagation Systems Inc

Booth C2329

PSI CB Series: The PSI CB series cavity backed broadband antenna is optimum for a single station or multiple stations. This antenna features a wide band dipole element that excites a cavity resonator, maximum beam control, extremely low VSWR and a uniform pattern with flat response across a wide band of frequencies. This antenna may be arranged for an omnidirectional or directional pattern. In the omni mode, circularity is ±2.0dB or better. Made of marine brass, copper and Teflon, this antenna is rugged and accepts deicers or radomes for environmental protection. The cavity itself is a galvanized welded mesh. Because of the extremely wide band frequency response offered by this antenna, the total number of frequencies is limited only by the total input power.

Portable surround sound mixing system


Booth N6129

Headzone PRO XT: As with the original Headzone system, Headzone PRO XT utilizes current DSP technology to provide superior headphone-based 5.1 surround sound reproduction. It also offers a unique patented ultrasonic-headtracking system, which locates the orientation of the listener's head with respect to the source material and adjusts the audio accordingly. Headzone PRO XT allows complete freedom of movement. The PRO XT includes enhanced headtracking functionality by providing more routing possibilities (left/right and front/back) in the software control panel. Also new to the PRO XT are added XLR inputs, an adjustable communication input with volume control, and a second headphone output. The Headzone PRO XT also allows for three individual user presets to be directly accessed through buttons on the unit's front panel and includes an adjustable, password protected limiter for hearing protection.
