3 Overview
The VP-2XLK is a high performance, desktop size, distribution amplifier for
computer graphics signals, with resolutions ranging up to at least UXGA, and
unbalanced stereo audio signals.
The VP-2XLK accepts one computer graphics input, and an unbalanced
stereo audio input, and outputs two computer graphics and two unbalanced
stereo audio signals. It includes the innovative Kramer integrated sync
processing; KR - ISP™ technology, which lets you achieve a sharp, stable
image when the sync level is too low, by restoring the sync signal waveform.
In particular, the VP-2XLK:
Has a high video bandwidth exceeding 400MHz, ensuring that it remains
transparent even at high-resolution graphics modes such as UXGA
(1600x1200)
Includes an AUDIO LEVEL control knob to adjust the audio signal level,
as well as UXGA LEVEL and UXGA EQ. control knobs to adjust signal
level, compensating for cable loss over long distances
Includes switches for ID Bit control and coupling
Is HDTV compatible
To achieve the best performance:
Connect only good quality connection cables, thus avoiding 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 and position
your Kramer unit away from moisture, excessive sunlight and dust
Caution – No operator-serviceable parts inside unit.
Warning – Use only the Kramer Electronics input power
wall adapter that is provided with this unit

.
Warning – Disconnect power and unplug unit from wall
before installing or removing device or servicing unit.

To connect the VP-2XLK, as the example in Figure 3 illustrates:
1. Connect a computer graphics source to the UXGA IN HD15F connector
and to the R and L AUDIO IN RCA connectors.
2. Connect the UXGA OUT HD15F connectors to up to
1
two acceptors (for
example, a display and a projector) and connect the respective R and L
AUDIO OUT RCA connectors to audio acceptors (for example, two
amplifiers with speakers).
3. Connect the 12V DC power adapter to the power socket and connect the
adapter to the mains electricity (not illustrated in Figure 3).
4. If required:
Check that the SYNC PROC. button is pushed in (the default), to activate
the sync processing
Adjust the AUDIO LEVEL, the UXGA LEVEL, and/or the UXGA EQ.
