In part one of this series we reviewed the 4 core design and technology components that are important for creating an effective AV room including video, audio, control and lighting. Although those are very important aspects of an effective environment, the technology “behind the scenes” is equally as important for creating a quality collaboration experience.
Understanding these background components is essential to recognizing what makes an AV room effective as a whole.
Wireless Mic Receiver: Used to pick up the signal broadcast by the mic transmitter and change it back into an audio signal. The output of the receiver is electrically identical to a standard microphone.
Audio DSP Processor/Mixer: A Digital Signal Processor, or DSP, is a special-purpose digital circuit that acts on digitized signals, such as audio. DSP circuits can replace traditional analog functions, such as filtering and more complex functions that are difficult to accomplish in the analog domain.
Amplifier: An electronic device for increasing the amplitude of electrical signals, used mainly in sound reproduction.
Video Matrix Switcher: A device for switching between multiple video sources including cameras, cable television, Blu-Ray, DVRs and more.
Control System Processor: A device that processes every signal sent out on an audio visual network and makes the signal available to all elements of an AV solution.
Surge Suppressor: An electrical device inserted in a power line to protect equipment from sudden fluctuations, or surges, in current which can damage equipment.
Codec: A device or program that compresses data to enable faster transmission and decompresses received data.
Seamless Video Switcher: A device used to select between several different video sources and, in some cases, composite video sources together to create special effects.
UPS Battery Backup: An electrical device that provides emergency power when the main power source fails. A UPS differs from an auxiliary or emergency power system or standby generator in that it will provide near-instantaneous protection from power interruptions, by supplying energy stored in batteries or a flywheel.
