Introduction
The Extron MDA 5 Series of Mini Distribution Amplifiers
(MDAs) are a family of three video and audio distribution
amplifiers. The MDA are members of the Extron VersaTools ™ line
of basic distribution amplifiers, switchers, and associated video
accessories.
The MDA 5V distributes buffered composite video, the MDA 5SV
distributes buffered S-video (luminance [Y] and chrominance [C]),
and the MDA 5A RCA distributes amplified stereo audio, on RCA
outputs.
The MDAs ship with external, desktop 12V power supplies,
which accept 100-240VAC input.
Installation
The MDA 5V, 5SV, and 5A RCA can be mounted on a rack shelf,
under a desk or tabletop, or on a projector bracket.
Rack mounting
UL considerations for rack mounting
The following Underwriters Laboratories (UL) considerations
are relevant to the safe installation of these distribution
amplifiers in a rack:
1
. Elevated operating ambient temperature — If the unit
is installed in a closed or multi-unit rack assembly, the
operating ambient temperature of the rack environment
may be greater than room ambient temperature. Therefore,
install the equipment in an environment compatible with
the maximum ambient temperature (Tma: +122 °F, +50 ° C)
specified by Extron.
2 . Reduced air flow — Install the equipment in the rack
so that the equipment gets adequate air flow for safe
operation.
3 . Mechanical loading — Mount the equipment in the rack
so that uneven mechanical loading does not create a
hazardous condition.
4 . Circuit overloading — Connect the equipment to
the supply circuit and consider the effect that circuit
overloading might have on overcurrent protection and
supply wiring. Give appropriate consideration to the
equipment nameplate ratings when addressing this
concern.
5 . Reliable earthing (grounding) — Maintain reliable
