AudiaEXPI & AudiaEXPO INTRODUCTION AudiaEXPI is an input expander for AUDIA®, the benchmark in digital audio systems for demanding professional sound installations. AudiaEXPI accepts eight mic/line analog audio inputs and provides eight channels of digital audio output via CobraNet®. AudiaEXPI can simply add inputs to a centralized system, or it can extend system boundaries by providing inputs in remote locations.
AudiaEXPI - Front & Rear Panels Peak Indicators (Inputs 1~8): These red LEDs will light whenever input channel signal levels reach +14dB (6dB below clipping). Use this feature to aid in the adjustment of the Trim controls (see below). Trims (Inputs 1~8): These screw-driver adjustable controls set the channel input gain (0dB ~ +60dB) to compensate for different source levels. This gain range will accomodate most microphone or line level signals.
AudiaEXPO - Front & Rear Panels Levels (Outputs 1~8): These screw-driver adjustable controls set the channel output gain (-70dB ~ 0dB) to provide appropriate signal levels to any subsequent audio equipment. Rotary Encoder & LCD Display: This control and display are used for initial setup of the AudiaEXPI unit. When power is first applied to the unit, the display will cycle through a product description, followed by a title screen. Press the control to enter setup.
APPLICATIONS Hotel with Sound Reinforcement in Multiple Banquet/Conference Rooms This application demonstrates the use of AUDIA in a hotel conference/banquet facility. This is a networked system using one AudiaFLEX 10x12CM unit and three AudiaEXPI 8-Input Expander units (forty-two inputs, twelve outputs, CobraNet). An example system diagram is shown on the next page. Each room has four microphones and two stereo line inputs, which are connected to an AudiaEXPI located within the room.
