2 Getting Started
We recommend that you:
•Unpack the equipment carefully and save the original box and packaging
materials for possible future shipment
•Review the contents of this user manual
Use Kramer high performance high resolution cables
Use only the power cord that is supplied with this machine
Go to http://www.kramerelectronics.com to check for up-to-date
user manuals, application programs, and to check if firmware
upgrades are available (where appropriate).
2.1 Achieving the Best Performance
To achieve the best performance:
•Use only good quality connection cables to avoid interference, deterioration
in signal quality due to poor matching, and elevated noise levels (often
associated with low quality cables)
•Avoid interference from neighboring electrical appliances that may adversely
influence signal quality
•Position your Kramer VA-50P away from moisture, excessive sunlight and
dust

VA-50P - Overview 3
3 Overview
The VA-50P is a 6-port 12V DC power supply. It replaces up to 6 separate 12 volt
adapters for Kramer TOOLS™ and other models that use 12V DC power
adapters.
In particular, the VA-50P:
•Is an efficient six outlet universal switching power supply that can output 12V
DC with up to 500mA per output (but not exceeding 2A total)
•Is designed to operate Kramer products that normally use an external 12V
DC power transformer
•Can be secured in a rack using the model RK-50RN kit that holds two
VA-50P units and requires two vertical spaces in a standard 19" rack
•Can save valuable space on power strips, by replacing up to six wall
transformers
Make sure that the polarity of the connected unit matches that of the
VA-50P – that is, the center pin is the positive terminal.
