Page 4: Introduction
Introduction 1 Introduction The TANDEM HD-20 is a High Definition video 24-bit two group audio analogue or digital embedder/de-embedder. It can be configured with two sub-PCB option cards to provide any of a number of possible functions at once, such as: •... - Page 5 Functions include audio shuffling, video delay, gain compensation and audio replace. The are two positions available on the TANDEM HD-20 for fitting optional sub-PCBs. The rear position 1 is associated with inputs 9-12 and outputs 1-4. The front position 2 with inputs 13-16 and outputs 5-8.
