Sierra Video Systems makes a complete line of high performance 10-output video and audio distribution amplifiers (DAs) for broadcast, production and presentation applications. Distribution Amplifiers are the unsung heroes of every video and audio facility, and every presentation application. DAs have the longest service life of any part of a facility. SVS DAs are still being used daily after being in service for over 17 years. Many of our DAs are reinstalled again in other capacities, extending their lives even further.
Our Series 10 DAs offer an extensive family of video and audio distribution amplifiers with 10 outputs each. These cost-effective plug-in amplifiers offer reliable, high-end performance at a very attractive price. Each member of the Series 10 DA family is a plug-in module for installation in a 19 inch rack mounting chassis. Each module uses a state of the art design to ensure the low distortion and wide bandwidth essential for transparent performance. Rack mounting frames accept 3, 10 and 20 modules.
The 3RU (5.25") Series 10 Audio DA frame accepts up to ten Series 10 mono and stereo audio modules. It provides 10 low impedance outputs per module with extremely flat frequency response and virtually 0% distortion. High precision, low noise components are used throughout the frame with front module adjustable gain control. The frame uses an internal power supply.
