INTRODUCTION/OVERVIEW
The Arbitron Studio Grade Encoder (SGE) inserts inaudible symbols into the audio of
broadcasts according to Arbitron patented algorithms. The instrument described in this
document, the Encoding Monitor (MONITOR), is used to detect encoded audio program
material. The station engineer can use this instrument to validate that their station is
transmitting encoded program material. Arbitron strongly advises the station engineer to
use
air
return
audio when connecting to the MONITOR, to detect cases where the SGE
has been accidentally ‘patched out’ of the audio stream.
RoHS Compliance (Restriction of Hazardous Substances) is the nickname given to the
European Union's directive 2002/95/EC on the restriction of the use of certain hazardous
substances in electrical and electronic equipment. RoHS seeks to reduce the amount of
hazardous materials entering electronic products.
The Arbitron “1000-1162-xx Encoding Monitor, RoHS Compliant” is designed to meet
the requirements of the European Union's directive 2002/95/EC.
All of the other Arbitron Encoding Monitors listed on the title page of this manual have
not been designed to meet the requirements of the European Union's directive
2002/95/EC.

Arbitron recommends that the MONITOR be installed such that it receives program
material that has exited the transmitter or ‘over-the-air’ broadcasts. This will insure that
your media consumers are exposed to encoded program material.
The MONITOR operates optimally with a nominal average audio input level of +8 dBu.
