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 Leitch Technology products
sold in the European Union will be fully RoHS-compliant and
“lead-free.” (See the Leitch Web site, www.leitch.com, 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. Leitch equipment that
complies with the EU directive will be marked with a RoHS-compliant
symbol, as shown in Figure 1.

Preface
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 the 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, Leitch Technology International,
Inc. and other companies selling electric or electronic devices in the
EU will affix labels indicating that such products must be properly
recycled. (See the Leitch Web site, www.leitch.com, for more
information on dates and deadlines for compliance.) Contact your local
Leitch sales representative for information on returning these products
for recycling. Leitch equipment that complies with the EU directive will
be marked with a WEEE-compliant symbol, as shown in Figure 2.

2 ADC-3981 Installation and Operation Manual
Chapter 1: Introduction
Product Description
The ADC-3981 consists of two independent audio processing units,
capable of handling two pairs (four channels) of analog audio inputs,
and two pairs of digital audio outputs. This module has full audio
processing capabilities, including gain, channel swap, invert, and delay
control. The ADC-3981 also has four independent tone generators.
Main Features
These are the main features of the ADC-3981 module:
• Two independent analog-to-digital conversion channels
• 32/44.1/48/96 kHz capability
• Selectable 16-, 20-, and 24-bit analog-to-digital conversion
• Internal audio processing amplifier
• Multiple tone generators (750 Hz, 1.5 kHz, 3 kHz, and 6 kHz)
• Four balanced analog audio inputs
• Peak/Silence/Tone indication
• Selectable delay for each channel
• Two balanced and two unbalanced AES audio outputs
• External video and DARS reference input
• Capability for control via card-edge, local control panels, remote
control panels, and GUI applications (3901RES-E resource module
is required for Ethernet use)

Front and Back Modules
Front Module
NEO front modules are designated by the suffix “-FM.” For example,
the front module of the ADC-3981 is the “ADC-3981-FM.” Figure 1-1
illustrates the position of the LEDs and card-edge controls on the
ADC-3981-FM front module.

Back Module
In the NEO frame, back modules are placed directly behind the front
modules. Back modules are designated by the suffix “-BM”. For
example, the back module of the ADC-3981 is the “ADC-3981-BM.”
