The DPA-90 Serial Digital Processing Amplifier provides the controls that are familiar in the analog world while working in a pure component 601 serial digital format. The Proc Amp provides control, via dedicated knobs, of six video parameters including: video gain, luminance gain, chroma gain, hue, pedestal (black level) and Y/C delay. Front panel LEDs provide constant system status monitoring. The system can be controlled either with front panel controls or with either of two optional, separate remote controls that operate over an RS-422 interface.
