Standards
Appendix A: “Safety Precautions, Certifications, and Compliances” contains
product compliance and safety standards.
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, which took effect on July 1, 2006, refers to the
following hazardous substances:
• Lead (Pb)
•Mercury (Hg)
• Cadmium (Cd)
• Hexavalent Chromium (Cr-V1)
Preface
• 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 website 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.

Preface
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. As of August
13, 2005, producers or users are 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 website 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.

680 Series Mounting Frames
The 680 series distribution amplifiers and mounting frames offer a
comprehensive range of signal handling capabilities for video, subcarrier, and
pulses. The equipment provides high quality, state-of-the-art circuitry that meets
the most demanding requirements for broadcast and program production
systems.
The universal mounting frames are designed to accept any type of amplifier in
any slot. Looping inputs and up to eight outputs per amplifier simplify solutions
to signal distribution and processing requirements, such as equalization,
clamping and delay.
The modular concept provides several fully wired mounting frame options that
facilitate system design and accommodate all of our distribution amplifiers:
• The FR-683 video DA mounting frame and the FR-683AV audio/video DA
mounting frame require one unit of rack space. The FR-683 and FR-683AV
contain one standard 684PS power supply. The FR-683 frame can house
any mix of up to four 8-output 680 series distribution amplifiers.
• The FR-684 Video DA mounting frame and the FR-684AV Audio/Video
DA mounting frame require two units of rack space. The FR-684 and FR684AV use the 684PS power supply. These frames are prewired to accept a
second optional power supply for power redundancy. A single power supply
is required per frame, while only one extra power supply is required when
several frames are interconnected.
• The FR-684 can house a mix of up to ten 8-outputs 680 series DAs.
• The FR-684AV can house five 680 series video DAs and five 880 series
audio DAs.

Frame Cooling
The equipment is designed to designed to operate in an ambient temperature
range of 32° F to 122° F (0° C to +50° C). No special provisions for cooling are
necessary, but you should take steps to prevent excessive heat rise in closed,
unventilated equipment racks.

Power Consumption
Each frame comes with a power supply and, in some cases, the frame is
prewired to accept an optional redundant power supply.
To prevent electric shock, do not use the (polarized)
plug with an extension cord, receptacle, or other outlet
unless the blades can be fully inserted to prevent blade
exposure.
Power consumption depends on how many modules are loaded in the frame,
how many outputs are being used, and what signals are being applied to these
modules. Table 1-1 lists the nominal power consumption for each frame.

PS-684 Power Supply
The model 684PS power supply is a two-stage switching power supply that
provides the following outputs:
+13V @ 1.5A
–13V @ 1.5A
Initial design criteria focused on maximizing efficiency and minimizing
individual component temperature rise. This has been achieved with a two-stage
design consisting of an input “Buck” converter feeding a high efficiency
push-pull output stage. Overall efficiency exceeds 80%; individual component
temperature rise is minimized by operating both converters at high voltage and
low current, as well as using Schottky rectifier diodes on the output stage. The
power supply is designed to work over the two standard input voltage ranges.
The power supply’s operating range is switchable between 90–135 VAC and
180–250 VAC. Output voltage is adjustable by ±10%. Other output voltages can
be achieved by changing power transformer TR1 without any additional circuit
changes.

The UDA-683 is a low-cost, utility video distribution amplifier for monitoring
and other distribution requirements where features such as differential input,
cable equalization, or clamping are not required. It can also be used for
subcarrier distribution. Despite its low-cost, frequency response and linearity
are excellent. Composite and component analog NTSC, PAL, SECAM signals,
with sync or without sync, and subcarrier signal can be distributed with
UDA683 in FR-683 and/or FR-684 series video distribution amplifier frames.
The UDA-683 provides eight outputs and delivers outstanding output density
with unmatched low-cost per output. The 100MHz bandwidth, low distortion,
excellent frequency response and wide gain range make the UDA-683 suitable
for general purpose distribution of all analog composite/component (NTSC,
PAL, and SECAM), subcarrier, and analog HDTV video signals.
The UDA-683 is a DC-coupled amplifier. It can be ordered with the optional
AC coupling, or field converted to AC coupling by the addition of input
coupling capacitors as indicated in “AC Coupling” on page 9.
