LZX - PGO

LZX PGO — Fundamental Video Mathematics

The PGO — (Programmable Gain & Offset) — brings the basics of analog video processing down to their clearest form. This module handles essential voltage operations - addition, subtraction, amplification, and attenuation - with remarkable precision and minimal fuss.

Its design follows a very straightforward approach — the normalled input jacks, marked by arrows on the panel, create different gain structures through simple patching choices. Each side of the difference amplifier includes a four-input summing stage, allowing for nuanced combining and processing of multiple signals before any subtraction occurs.

The built-in 1V reference output matches standard peak white level, making it particularly useful for precise mask creation and system calibration. The module's fully differential architecture provides both positive and negative outputs, essential for sophisticated video processing tasks.

The PGO's patch-programmable nature means its behavior changes based on your connections rather than knob positions. This approach creates a direct relationship between patching and function - want a buffer? Patch it one way. Need an inverter? Patch it another. Their onine guide should provides numerous patch examples. All in all, rack real-estate well spent — solid fundamentals.
