The VP-438 Presentation Switcher / Scaler:
signals on RCA connectors. It scales the video, embeds
the audio, and outputs the signal to the HDMI output, as well as to a computer
graphics output and an RGBHV video output with digital audio and analog
stereo audio outputs.
• Is HDTV compatible and the resolution can be up- or down-scaled
2
• Is HDCP compliant, the HDCP (High Definition Content Protection)
license agreement allows copy−protected data on the HDMI input to pass
only to the HDMI output
• Output signal is available in three formats: 1 HDMI and 2 RGBHV (on 5
BNC connectors, and one 15−pin HD connector)
• Has analog audio inputs which include volume control, and digital
(S/PDIF) and analog stereo audio outputs
• Automatically detects and selects the audio source for the HDMI input.
Default selection is HDMI – if this is not present, then the machine uses
the audio from the analog input
• Comes with an On-Screen Display (OSD) for easy setup and adjustment,
accessible via the IR remote control and via the front-panel buttons
• Has a non-volatile memory that retains the last settings used
• Supports firmware upgrade

• Directly, via the front panel push buttons
• By RS-232 serial commands transmitted by a touch screen system, PC, or
other serial controller
• Remotely, from the infrared remote control transmitter
The VP-438
is housed in a 19” 1U rack mountable enclosure, with rack “ears”

3.1 Recommendations for Best Performance
To achieve the best performance:
• Connect only good quality connection cables, thus avoiding interference,
deterioration in signal quality due to poor matching, and elevated noiselevels (often associated with low quality cables)
• Do not secure the cables in tight bundles or roll the slack into tight coils
• Avoid interference from neighboring electrical appliances and position
your Kramer VP-438 away from moisture, excessive sunlight and dust
