Electromagnetic Radiation Notice
The following information is given to note compliance with the United States Government Federal Communications
Commission (FCC) Rules (47 CFR Part 15) designed to limit interference to radio and TV reception. The ruling establishes
measurement procedures and frequency criteria for Class A computing devices (commercial and industrial applications) with
the following conduction and radiation limits:
CLASS A COMPUTING DEVICE: CONDUCTION LIMIT (Part 15.812)
Frequency (MHz) Maximum RF Line Voltage (uV)
0.45 -1.6 1000
1.6 -30 3000
CLASS A COMPUTING DEVICE: RADIATION LIMIT (Section 15.810)
Frequency (MHz) Distance (meters) Field Strength (uV/m)
30 -88 30 30
88 -216 30 50
216 -1000 30 70
The policy of Thomson is one of continual development and improvement. For that reason Thomson uses components and
manufacturing techniques that provide the current state-of-the-art suppression of electromagnetic radiation. This equipment, in
production before October 1, 1981, has not been tested to the above listed measurements. However, equipment such as this
delivered after October 1, 1983 will have the measurements on record at the factory. Therefore, in compliance with the stated
FCC Regulation, the following information is provided for the user:
NOTE
Interference to Radio Communications
This equipment generates, uses, and can radiate radio frequency energy and if not installed and used
in accordance with the instruction manual, may cause interference to radio communications. As
temporarily permitted by regulation it has not been tested for compliance with the limits for Class A
computing devices pursuant to Subpart J of of Part 15 of FCC Rules, which are designed to provide
reasonable protection against such interference. Operation of this equipment in a residential area
is likely to cause interference in which case the user at his own expense will be required to take
whatever measures may be required to correct the interference.

1General
The Media-8 is an RGBHV Analogue Video + Stereo Analogue Audio (optional) 8x8 Router for
Multimedia applications. The Video Router has seamless tri-step switching, or vertical interval switching,
and a large signal bandwidth, which provides high performance up to 1600x1200 resolution. The Audio
Router has balanced inputs and outputs, and audio breakaway allows selecting audio independent from
video. A preset editor allows the user multi-crosspoint settings in one operation, and multi panel interface
allows control of the router from up to 20 different sites.
This top of the line Router provides high performance circuits in SMD technology, with no discernible
signal degradation. The built-in RS-232 interface allows the user to control the router via the Triton
Router Control System PC software with many operational features. The control bus allows linking of the
unit to other Triton Routers and Control Panels, all designed to suit the needs of the user.
The following formats may be configured (stereo audio is optional):
8x8 RGBHV + AA
