2. NOTICE
For the 1000-11 5-xx Encoding Monitor:
The two cylindrical ferrite cores, Fair Rite part #0431164281 or its functional equivalent,
supplied as part of the package, must be installed on the two audio cables in close
proximity to the Neutrik XLR connector, close to the connection point at the rear of this
Encoding onitor. (See Figure 1)
To install these devices, simply open the core’s hinged case and fit the sectioned cores
over the cables; once the case is snapped closed, the cores will be firmly secured (see
picture on next page).
The installation of these ferrite cores is not necessary for the 1000-1162-xx Encoding
onitor, RoHS Compliant.

4. WARNINGS
To reduce the risk of personal injury, electrical shock, fire, or damage to the ONITOR,
DO NOT expose this unit to rain or moisture. Due to the danger of personal injury,
electrical shock, or damage to the instrument, ONLY Arbitron authorized service
personnel shall gain access to the inside of the ONITOR. DO NOT disconnect the
earth ground from the power cord since this is a very important safety feature. The
ONITOR should be mounted securely in a rack. The sides must be free of obstructions
to provide adequate airflow through the instrument.
The installation of the ferrite cores is of paramount importance for maintenance of
compliance to the FCC part 15 and CISPR 22 Radiated Emission Class “B” Normative.
CAUTION: FAILURE TO INSTALL THE ENCODING MONITOR IN
ACCORDANCE WITH THE SPECIFICATION IN THIS MANUAL AND/OR
FAILURE TO MAINTAIN BROADCAST SIGNALS IN ACCORDANCE WITH
GENERAL INDUSTRY STANDARDS AND SPECIFICATIONS MAY RESULT
IN THE ENCODING MONITOR NOT OPERATING PROPERLY.

5. 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 onitor ( ONITOR), 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 ONITOR, 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 onitor, RoHS Compliant” is designed to meet
the requirements of the European Union's directive 2002/95/EC.
All of the other Arbitron Encoding onitors 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.
5.1. S UGGESTED P LACEMENT IN A UDIO C HAIN
Arbitron recommends that the ONITOR 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 ONITOR operates optimally with a nominal average audio input level of +8 dBu.

6. INSTALLATION
6.1. I NSTALLING THE MONITOR
6.1.1. Place instrument into a 19” rack in an indoor environment.
6.1.2. Install securely using screws in each of the four front panel corners.
6.1.3. See Figure 2. Slide switch ‘S1’ to ‘600’ if 600 ohm input termination is desired or to
‘HI’ if a 12k ohm input bridging impedance is desired.
6.1.4. Connect the power cord to the ONITOR and to the same plug strip that supplies power
to the instruments that will be connected to the input of the ONITOR. The ONITOR
has no power switch. The ‘POWER’ indicator LED will be lit green.
6.1.5. DO NOT block or otherwise impede airflow through the sides of the instrument.
6.1.6. Connect the received program material signals into the connectors marked ‘IN’ on the
ONITOR.
If the program material is always mono and only one audio cable is used (single
channel mode), then the MONITOR can be configured for single channel operation.
In single channel mode, the channel A analog input must be used. The default
decoding mode is dual channel.

7. OPERATION
7.1. U SING THE MONITOR
The station engineer has been provided several monitoring options:
If desired, they can monitor the front panel LED. When the ONITOR is receiving the
correct encoded material, the front panel LED will be a CONSTANT GREEN. When
incorrectly encoded material is presented to the audio inputs, the front panel LED will
FLASH RED (see notes below).

If the engineer cannot always visually monitor the ONITOR front panel, the engineer
can use the rear panel ALAR connection. This connection provides both a normally
open and normally closed relays which will energize when indicating a loss of encoding.
This connection can be made externally to either an audible or visual indicator, or both.
It is highly recommended that the monitor’s ALAR connection should be used in
conjunction with your station’s current Air Fault Alarm system (or similar).
Provision has also been made for connection to a remote monitor device via RS232. See
below for specification of connection to both the ALAR and RS232 connections.
Note: The MONITOR has been configured with a nominal alarm delay of approximately
3 minutes. In other words the MONITOR will not assert an alarm condition until it fails
to detect the specified code for approximately 3 minutes. At that time the alarm relay
will close (or open) the LED will turn RED and a statement will be issued via the RS232
connection. When an encoded signal is applied to the input the MONITOR will release
the alarm condition immediately. Please see below for information on the specifics of the
alarm assertion.
