Equipment Manual: Encoder 1000-1161
Document #: 1050-1475
Revision: F
1. Introduction
The Studio Grade Encoder (SGE) is a device that inserts inaudible symbols into the audio stream of
broadcasts according to the Critical Band Encoding Technology (CBET) algorithms. The symbols are
easily received and recorded by a Portable People Meter (PPM) when exposed to the encoded
broadcasts.
Nielsen Audio provides a number of different interface models for the SGE. This manual references
models that provide the interface to a digital (AES/EBU) audio chain using industry standard XLR or
BNC connectors.
The Nielsen Audio Encoder listed on the title page of this manual has been designed to meet the
requirements of the European Union's directive 2002/95/EC, commonly known as RoHS (Restriction
of Hazardous Substances) Compliance. This directive restricts the use of certain hazardous
substances in electrical and electronic equipment. RoHS seeks to reduce the amount of hazardous
materials entering electronic products.
