feed to DA-43A
2) input. Connect one output to your Monitor, switcher or VCR. and verify that the hum is reduced or
eliminated.

unterminated with no affect on the signals on the other channels.

Trouble shooting: The input stage of the DA-43 series distribution amplifiers is a differential type. This
is used to minimize the potential for ground loops. This does not mean that there will not be ground loops in
the system. The outputs to the monitors are all common and can create ground loop problems. The ground
difference between the camera and the DA can be so great as to overcome the differential amplifiers
capabilities.
If a ground loop condition occurs: Disconnect all of the outputs of the DA except one. If the groundloop goes
away and you get a clear picture, your problem is between the monitors and not the camera to DA feed. If the
groundloop problem still exists with only one monitor, the Camera side groundloop problem is severe and a
hum bucking transformer is recommended.
To solve the monitor side groundloop problem:
Most of the time the problem is on the cable that connects the furthest point. When testing for monitor side
ground loops, leave this cable for last. Begin by connecting the closest monitor to a DA output. Then add a
second monitor and check for ground loops. If there are none, disconnect the second cable, mark it as good
and connect another monitor and again check for any problems. Continue checking each cable until all of the
individual monitors have been checked. Now reconnect all of the monitors, one at a time and watch for the
ground loop problem to appear. Usually you will find that the problem is caused by one feed only and
by using a DA-20 or a Hum bucking transformer at the monitor location, the problem will go away.

MDS-14/16 Series
WARNING! The DC power cannot be the from the same supply as the DC camera or video source. It must
be from an isolated source. For units that can work with a common DC source use the MDS-12.
+12VDC (WIRE WITH WHITE TRACE)
GND (WIRE WITH NO TRACE)
DA-14/16 Series:
The DA-14 and the DA-16 are 1 in and 4 out for the DA-14 and 1 in and 6 out for the DA-16. These DA's
have a standard input terminated in 75 ohms. Any unused outputs can be left unterminated.
