Analog-Digital Panel Type H903

This document serves as a technical product specification for the Analog-Digital Panel Type H903, a component designed for experimenting with analog-digital techniques. The panel features a 4-bit variable output digital-to-analog (D-A) converter, a comparator circuit, two 8-volt panel meters, and a potentiometer for generating a 0 to -8V test signal. Connections are made using Type 911 stacking banana-jack patchcords. The document outlines specific electrical characteristics, including converter offsets, impedance, and power requirements, as well as mechanical specifications such as dimensions, finish, and connector types.
