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)

According to 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>company>environmental

compliance, 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) 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 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,

www.broadcast.harris.com/leitch>company>environmental

compliance, 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.

Chapter 1: Introduction

Product Description

The NEO AES-3981 is a digital audio distribution amplifier for AES/

EBU audio signals for the NEO range of products. This module, as is

the case with all modules in the NEO family, can be controlled locally

via a front-edge display or from a remote location. Its remote

communications capability allows for control, monitoring, and

diagnostics using hardware control panels and/or a graphical user

interface.

The 1RU NEO control panel is uncluttered and simple to use. It has as

large a display as is practical, and a suitable number of buttons and

knobs to allow easy menu selection and parameter adjustment. The

aesthetic appearance of the panel is similar to that used for the 3RU

NEO Control panel, and matches the global Leitch/Harris styling

requirements.

The AES-3981 is a fully-featured single module product that includes a

front plug-in card module and back modules with balanced or coaxial

digital audio interfaces. Card edge and remote control of reclock mode,

EQ mode, and Alarm classification is provided. Signal presence is

provided locally and remotely.

Chapter 1: Introduction

Applications

The NEO platform is ideal for space-constrained operations demanding

full local and remote control capabilities in a routing solution. It is

especially useful where professional end-users require a small, flexible,

high quality (on-air quality) routing matrix with the ability to mix and

match signal formats and/or signal processing functions within the

same frame:

• Television production facilities

• Cable operators

• Production and post-production facilities

• Outside broadcast vans/trucks

• DBS satellite operations

AES-3981 Installation and Operation Manual 5

Chapter 1: Introduction

Preliminary—Contents are proprietary and confidential. Do not photocopy or distribute.

Major Components

The AES-3981 consists of a front module and a back connector module.

The front module is installed from the front of the frame, and is

hot-swappable. The back connector module is installed from the rear of

the frame.

The front module accepts a single input signal from the back panel, then

equalizes and conditions the signal before driving the signal to eight

separate outputs. The input signal may also be reclocked if desired.

Front Module

Figure 1-1 illustrates the LEDs on the front module of the AES-3981.

Front modules are designated by the suffix “-FM.” For example, the

front module of the AES-3981 is the AES-3981-FM.

Chapter 1: Introduction

Back Connector Module

The back modules provide the interface between the main module and

the signal cables. The coaxial back module contains one looping BNC

input and 8 BNC outputs. The balanced back module provides an input,

which is either terminated or looping, selectable via a back module

jumper. The one input and the eight outputs are transformer coupled,

with connectors being removable terminal strips.

In the NEO frame, the AES-3981 back connector module is placed

directly behind the front module, facing the rear. The AES-3981

supports either a coaxial interface or a balanced interface back module.

The balanced back module features 110Ω output impedance with a

jumper-selectable looping or 110Ω-terminated input. The input on the

AES-3981-B is bridging and may be used as such; however, we

recommend that the input be terminated with the back module

jumper for proper input return loss specification. Figure 1-2

illustrates balanced back module connections.

The coaxial back module features 75Ω output impedance and a looping

input. The input on the AES-3981-C is high impedance (looping)

and may be used as such; however, we recommend that the input be

terminated with a 75Ω termination for proper input return loss

specification. Figure 1-3 illustrates coaxial back module connections.
