Audio International AV-9693 Owners manual

						Audio/Video Distribution Unit
a DeCrane Aircraft Company							A/V-9693-0x-x
Product Description
Audio International’s A/V-9693-0x-x is a DO-160 tested
integrated audio/video controller that provides multiple source
selection, multiple output distribution, a high fidelity audio power
amplifier, and complete PA/chime functionality. This integrated
cabin entertainment unit cuts both cost and weight, frees valuable
aircraft space, and simplifies wiring.
Eight (8) entertainment audio and video sources inputs; 16
audio (headphones) and 16 video stations outputs; and four (4)
speaker outputs that can be configured for either full-range
speakers or subwoofers make the A/V-9693-0x-x an excellent
choice for premium cabin entertainment systems. Dual ten-band						Two (2) PA/chime audio outputs to interface with other aircraft
