DA-10 1x10 Stereo Audio/Video Duplication Amplifier
The DA-10 is a 1 input, 10 output video and stereo audio distribution amplifier, intended for use in duplication facilities. The unit
occupies 1 rack unit (1RU) of space.
Video and audio gains are adjustable, and the controls are accessible from the front of the unit.
The video input is looping. Video connectors are available as either RCA or BNC.
Audio inputs are both balanced XLR and 1/4" TRS connectors, and audio outputs are the unbalanced RCA type, in order to
interconnect easily with most types of duplication equipment.
The DA-10 is designed to deliver broadcast quality audio and video reproduction in a compact enclosure. Durable construction,
excellent specifications and dependable circuitry ensure reliability throughout the rigors of daily use.
