DPA-100

Serial Digital Processing Amplifier

The DPA-100 Serial Digital Processing Amplifier provides the controls that are familiar in the analog world while working in a pure component serial digital format. The unique automatic Broadcast Legal function monitors the signal and looks for colors which, while legal in the component digital environment, fall outside the limits legal for NTSC or PAL broadcast. The DPA-100 automatically adjusts these values to provide a clean, properly modified signal to feed an encoder, transmission system or storage device.

The DPA-100 also provides control, via dedicated knobs, of six video parameters including: Video Gain, Luminance Gain, Chroma Gain, Hue, Black Level and Y/C Delay. Front panel LED’s provide constant system status monitoring. The system includes two optional, separate remote control units that operate over an RS-422 interface.

Features

Automatic broadcast legalization using phase coherent chroma clip
Automatic detection of 525/60 or 625/50 digital formats
Full resolution, 10-bit processing
Full EDH support and alarms
Passive bypass in case of power loss
Standards available: 525/60 and 625/60, NTSC-J optional
Two optional remote control panels (up to 300 meters from DPA-100)
Optional, NTSC-J auto legal format

Product Details

RCU-100M Expanded Function Remote Control

Permits multiple DPA-100’s (up to 32) to be controlled from a single point
With RCU-100M, the auto-legal settings are continuously adjustable over a wider range than on the DPA-100 alone
Limits may be set independently for 525 and 625 signal inputs
Display includes numeric readout of processing and auto-legal settings
Desktop or rackmount (half-rack wide, 3RU tall - fits in standard scope mount)
