Restriction on Hazardous Substances (RoHS)
Compliance
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)
According to this EU Directive, all products sold in the European Union
will be fully RoHS-compliant and “lead-free.” (See our Web site 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 emblem,
as shown in Figure P-1.

Waste from Electrical and Electronic
Equipment (WEEE) Compliance
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 may 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
products must be properly recycled. (See our Web site for more
information on dates and deadlines for compliance.) Contact your local
sales representative for information on returning these products for
recycling. Equipment that complies with the EU directive will be
marked with a WEEE-compliant emblem, as shown in Figure P-2.

Safety
Carefully review all safety precautions to avoid injury and prevent
damage to this product or any products connected to it. If this product is
rack-mountable, it should be mounted in an appropriate rack using the
rack-mounting positions and rear support guides provided. It is
recommended that each frame be connected to a separate electrical
circuit for protection against circuit overloading. If this product relies
on forced air cooling, it is recommended that all obstructions to the air
flow be removed prior to mounting the frame in the rack.
If this product has a provision for external earth grounding, it is
recommended that the frame be grounded to earth via the protective
earth ground on the rear panel.
IMPORTANT! Only qualified personnel should perform service
procedures.

Overview
Chapter 1
Introduction
The DAC6800+BCA4 and DAC6800+BCA4Z are four-channel
digital-to-analog audio converters that support two AES inputs and four
analog audio output channels. Both versions generate either unbalanced
or balanced AES inputs, and balanced analog outputs. The DAC6800+
BCA4Z generates 600 ohms of output impedance, while the
DAC6800+BCA4 generates 66 ohms of output impedance.
The following topics appear in this chapter:
•“Product Description” on page 2
•“Module Descriptions” on page 3
•“Signal Flow” on page 6
DAC6800+BCA4 and DAC6800+BCA4Z Installation and Operation Manual1
Chapter 1: Introduction
Product Description
The DAC6800+BCA4/4Z Four-Channel Digital-to-Analog Converter
converts two AES inputs to four analog audio output channels. All
versions support either unbalanced or balanced AES inputs, and
balanced analog outputs. These options are all set via jumpers on the
board itself. The DAC6800+BCA4Z outputs 600 ohms output
impedance.
Main Features
These modules can be monitored locally via the card edge, or remotely
with control software applications such as CCS
Pilot™, and CCS Navigator™, or control panels LCP-3901-1U and
RCP-CCS-1U, or other CCS-compliant products.
Two module types are available:
•DAC6800+BCA4 has two AES inputs and four analog audio
output channels at 66 ohms.
•DAC6800+BCA4Z has two AES inputs and four analog audio
output channels at 600 ohms.
The back connectors require two frame slots within an FR6802+ frame
(there is no backward-compatibility provided for use with 6800/7000
series frames).
Other DAC6800+BCA4/4Z Four-Channel Digital-to-Analog Converter
features include the following:
•Supports 32 kHz to 96kHz sampling frequency
•16, 20 or 24 bit audio processing
•Analog output levels of:
•16,18, 20, 22, 24, 26 and 28 dBu (66 ohms)
•10,12, 14, 16, 18, 20 and 22 dBm (600 ohms)
•Integrated remote PC-based control capability (using CCS control
software and control panels)
•Card edge control
TM
+Pilot Lite™, CCS™
•LEDs for AES input presence and AES input errors
•Four analog audio output channels (66 ohms or 600 ohms)
•Two jumper selectable AES balanced or unbalanced inputs

This switch navigates up and down through the available
control parameters:
• Down: Moves down through the parameters
• Up: Moves up through the parameters
Each 6800+ module has a number of LEDs assigned to
indicate varying states/functions. See “Monitoring

LEDs.
• Local: Locks out external control panels and allows
card-edge control only; limits the functionality of
remote software applications to alarm monitoring
• Remote: Allows remote or local (card-edge)
