Safety Standards and Compliances
See the 6800+Safety Instructions and Standards Manual to find the
safety standards and compliances for this 6800+series product. A
safety manual is shipped with every FR6802+Frame Installation and

Restriction on Hazardous Substances (RoHS) Directive
Directive 2002/95/EC—commonly known as the European Union (EU)
Restriction on Hazardous Substances (RoHS)—sets limits on the use of
certain substances found in electrical and electronic equipment. The
intent of this legislation is to reduce the amount of hazardous chemicals
that may leach out of landfill sites or otherwise contaminate the
environment during end-of-life recycling. The Directive takes effect on
July 1, 2006, and it refers to the following hazardous substances:
• Lead (Pb)
• Mercury (Hg)
• Cadmium (Cd)
• Hexavalent Chromium (Cr-V1)
• Polybrominated Biphenyls (PBB)
• Polybrominated Diphenyl Ethers (PBDE)
In accordance with this EU Directive, all products sold in the European
Union will be fully RoHS-compliant and “lead-free.” (See our Web site,
www.broadcast.harris.com/leitch, for more information on dates and
deadlines for compliance.) Spare parts supplied for the repair and
upgrade of equipment sold before July 1, 2006 are exempt from the
legislation. Equipment that complies with the EU directive will be
marked with a RoHS-compliant symbol, as shown in Figure P-1.

Waste from Electrical and Electronic Equipment
(WEEE) Directive
The European Union (EU) Directive 2002/96/EC on Waste from
Electrical and Electronic Equipment (WEEE) deals with the collection,
treatment, recovery, and recycling of electrical and electronic waste
products. The objective of the WEEE Directive is to assign the
responsibility for the disposal of associated hazardous waste to either
the producers or users of these products. Effective August 13, 2005,
producers or users will be required to recycle electrical and electronic
equipment at end of its useful life, and must not dispose of the
equipment in landfills or by using other unapproved methods. (Some
EU member states may have different deadlines.)
In accordance with this EU Directive, companies selling electric or
electronic devices in the EU will affix labels indicating that such prod-
ucts must properly recycled. (See our Web site, www.broadcast.har-
ris.com/leitch, for more information on dates and deadlines for
compliance.) Contact your local Sales representative for information on
returning these products for recycling. Eequipment that complies with
the EU directive will be marked with a WEEE-compliant symbol, as
shown in Figure P-2.

Chapter 1: Introduction
Product Description
AES6800+is a digital audio distribution amplifier module set in the
new 6800+family. The AES6800+features cable auto-equalization,
data reclocking, and incoming data error detection and reporting. The
error detection and reporting features use front-mounted LEDs and an
external alarm reporting. Housed in an FR-6802+series frame, this
distribution amplifier meets the AES interface standards according to
SMPTE 276M, AES3 1992 (r 1997), and AES3 id-2001.
These DAs feature high audio performance, low cost, remote
monitoring, and diagnostic capability in our control system.
You can set up and monitor the AES6800+locally via DIP switches.
You can monitor error signals and card status remotely on a PC. For
remote monitoring, you can use either a serial RS-232 or optional
ICE6800+Ethernet connection.
Typical Broadcast and Production Applications
The AES6800+distribution amplifier can be used in broadcast, cable,
production, educational, and auditorium applications where a low cost
method of distributing AES/EBU digital audio signals is required.
Main Features
• Available in balanced (AES6800+B) and coaxial (AES6800+C)
I/O formats
• Distribution of one signal input into four or nine isolated outputs
• Input signal lock detect
• Automatic or manual EQ
• Sampling frequency from 30 kHz to 192 kHz
• Bypass mode for non-AES signals of < 30 MHz @ 50% duty cycle
• Automatic reporting of data or signal quality errors, such as
• CRC errors
• Validity
• Confidence
• Biphase encoding errors
• Parity errors
