3 Overview
The Kramer
VP-23DS
is a high quality presentation switcher / Scaler
designed for a wide variety of presentation and multimedia applications. The
VP-23DS
includes three independently controlled switcher groups that
combine the functions of a 2x1 switcher for composite video, a 2x1 switcher
for s-Video, and a 4x1 switcher for computer graphics VGA/UXGA type
signals. Each video input has its own unbalanced stereo audio input. There is
also an independent unbalanced stereo master audio output, which can select a
signal from any of the eight audio inputs.
The
VP-23DS
features an additional Scaler output at which the selected video
signal (composite or s-Video) is converted to a VGA output (resolution can be
scaled up to WXGA).
In addition, the
VP-23DS
:
Includes eight input selector buttons, control buttons for the master audio
output level, microphone level, as well as buttons for selecting the Scaler
mode and the Scaler resolution
Features a FOLLOW button to toggle between the follow and breakaway
mode
Has a LOCK button to prevent unintentional tampering with the front
panel buttons
Is designed so that each switcher group can be controlled independently
from the other sections
Lets you insert an additional microphone channel by mixing with the
master output signal or by muting the master output signal
The
VP-23DS
can be controlled via the front panel buttons or by RS-232
serial commands transmitted by a touch screen system, PC, or other serial
controller. It is housed in a 19” 1U rack mountable enclosure, with rack “ears”
included, and is fed from a 100-240 VAC universal switching power supply.
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
