Getting Started

Packaging

The shipping carton and packaging materials
provide protection for the module during transit.
Please retain the shipping cartons in case
subsequent shipping of the product becomes
necessary.

Product Description

The D VA 3720 / D VA 3720 L is a high quality
analog video distribution amplifier designed
primarily for broadcast and professional
applications.

Flexible configurations allow the D VA 3720 to be
used in dual 1 to 4 applications or 1 to 8
applications, the D VA 3720 L has passive loop
through outputs for both inputs and 3 outputs per
channel. Both units are with independent gain and
equalization adjustment for each channel. The
module is microprocessor controlled and
configuration, gain level and equalization are set
using local controls included on the module. All
settings are stored in internal flash ram. Presence
detection is provided via status LEDs and a front
side alarm LED is also provided.

The D VA 3720 and D VA 320 L is part of the 3000
series of MiniModules, which offer high quality,
modularity and flexibility in a very small form factor
ideal for applications where space is at a premium.

The modules can be used either stand alone using
the optional power supply brick, or as part of a
tightly integrated space saving system wh ere up to
10 MiniModules can be mounted utilizing the
optional LYNX R FR 3005/3010 rack housing. This
includes integrated power supply and optional
remote control interfaces.

Functional Diagram

Figure 1 below is the basic functional diagram for
the D VA 3720 / 3720 L MiniModule.

Figure 1- D VA 3720 / 3720 L Functional Diagram

Module Layout

Figure 2 shows the physical layout of the D VA 3720
MiniModule. Video I/O is made through standard
BNC video connectors. Module configuration is set
via a small dip-switch and push buttons located
behind a small access hole in the bottom of the
module. When used in single mode (1x1:8) IN 1 is
used as the input signal.

If the module is being used in a stand alone
application then the optional power supply (R PS
3601 E, R PS 3601 U or R PS 3601-3) is required to
power the module (not shown)
