AVD0001C01

1. DESCRIPTION

1.1. The AVD0001C01

The AVD0001C01 is a wide bandwidth analog video distributor for standard definition
(525 and 625 lines) and high definition (720p, 1080i and 1080p) signals. It is comprised
of one section that can distribute a loop-through input signal to eigth outputs.

The AVD0001C01 includes a DC-coupled amplifier-distributor between the input and
the outputs, a DC restorer with two operating mode (fast and slow) and an equalizer
capable of compensating up to 300 meters of Belden 1694A controlled by two
potentiometers on the side of the unit. The AVD0001C01 also allows the input to be
terminated by 75Ω when a loop-through connection is not required.

The AVD0001C01 includes an ON LED on the front panel to indicate when electrical
power is connected, an LED to indicate the presence and format of the video signal being
distributed and three switches to configure the DC restorer and the input termination.

The AVD0001C01 has been designed to operate independently and hence does not
require installation in a rack. The unit features robust aluminum construction and
supports a wide range of operating temperatures.

The AVD0001C01 is powered by an external wall adapter supplied with the equipment.
The power supply connection has a security system that attaches the power cable to the
equipment case with a threaded connector, avoiding any mechanical stress on the cable
due to accidental disconnection.

The CrossConnect family from Albalá Ingenieros is a set of products for all kinds of signal
processing and distribution characterized by portability, mechanical robustness and low
power consumption. These properties make it perfectly suited to field deployment
needs, however the use of highly reliable components also make the CrossConnect
family suitable for both temporary and permanent fixed installations.

The AVD0001C01 is a member of the CrossConnect products family.
