To adjust the audio input to Microphone Level for either subcarrier, position the
corresponding slide switch to MIC as indicated on the unit label. To adjust the audio
input to Line Level for either subcarrier, position the corresponding slide switch to LINE
as indicated on the unit label.
When two subcarriers are specified, Audio Level switches are designated as AUDIO-1
LINE / AUDIO-1 MIC and AUDIO-2 LINE / AUDIO-2 MIC on the unit label.
When 100 kHz subcarrier frequency response is specified on either or both subcarriers,
the Audio Level switch for the corresponding subcarrier(s) is inactive and the 100 kHz
data is transmitted at a constant FM deviation sensitivity (no ALC).

Use of Heat Sink
All VT50 Series Transmitters except UHF 10 Watts must utilize AMP Heat Sink
VH2505 (0.5” high) or be securely fastened to an adequate heat sinking object or surface.
VT50U UHF 10W or 2/5/10W transmitters utilize AMP Heat Sink VH2513 ((1.3” high).
VT50 transmitters should be fastened to AMP heat sinks using provided 4-40x11/16” pan
head or socket head screws with #4 lock washers. Use of thermal grease, such as
Wakefield Engineering 120 Series Thermal Compound, to improve thermal conduction
between transmitter baseplate and heat sinking surface will reduce unit temperature and
increase product reliability.
Caution: Failure to provide adequate heat sinking VOIDS PRODUCT
WARRANTY.
4.4
Initial Adjustments and Settings
There are no initial adjustments or settings necessary to use AMP Transmitters other than
proper configuration of the slide switches as outlined above in Section 4.2. To assure
optimum performance, the user should be familiar with the camera, monitor, microphone,
and speaker/headphones used with this video/audio system.
4.5 Shut
Down
If the transmitter is to be shut down only briefly, simply remove DC voltage from the DC
Power Cable or disconnect DC Power Cable from transmitter. If the unit is to be shut
down for an extended period, all external cabling including the antenna should be
removed and the unit should be stored in a container and placed in a clean, dry
environment.
5.0 MAINTENANCE
INSTRUCTIONS
5.1 Cleaning
AMP Transmitters should be periodically wiped off with a clean, damp cloth. For more
thorough cleaning, dampen a clean cloth with glass cleaner and wipe off unit. Ensure
units are completely disconnected from their power sources before cleaning.
