VP-773A - Overview
3 Overview
The Kramer VP-773A is a high quality presentation switcher and scaler. It accepts
one of eight inputs: a DisplayPort (DP) signal on a DisplayPort connector, one
composite video signal on an RCA connector, two computer graphics signals on 15-
pin HD connectors, and four HDMI signals on HDMI connectors. It scales the video,
embeds the audio, and simultaneously outputs the signal to two HDMI outputs and
to an HDBaseT TP output, together with a digital audio output and a balanced
stereo audio output.
The VP-773A Presentation Switcher / Scaler features:

customizable windows’size and position control: any source can be inserted
into or positioned next to any other source and resized as desired
Ultra-Fast Fade-Thru-Black (FTB™) Switching - Video switching transitions
are clean and ultra-fast. The video fades to black and the new input fades
from black for smooth, glitch-free switching. The output signal provides
constant sync so the display never glitches
An emergency alert system that can have a national or campus-wide
notification immediately displayed when an emergency situation develops, by
means of automatic text overlaying, either via a crawler or a full screen cover

VP-773A – Overview
7
The VP-773A 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.
3.1 HDCP Compliance
If an HDMI signal is HDCP protected, it can only appear on HDMI and
HDBaseT outputs that are connected to HDCP compliant displays.
The VP-773A will not output an HDCP protected source to a display that
is not HDCP compliant. Instead it will show a green screen.
In the dual window display mode (see Section 7.2), even if only one of
the inputs is HDCP protected, and is output to a non-compliant display,
it will affect the entire screen and turn it green.
3.2 About HDBaseT™ Technology
HDBaseT™ is an advanced all-in-one connectivity technology (supported by the
HDBaseT Alliance). It is particularly suitable in the ProAV –and also the home –
environment as a digital networking alternative, where it enables you to replace
numerous cables and connectors by a single LAN cable used to transmit, for
example, uncompressed full high-definition video, audio, IR, as well as various
control signals.
The products described in this user manual are HDBaseT certified.
3.3 Using Twisted Pair Cable
Kramer engineers have developed special twisted pair cables to best match our
digital twisted pair products; BC−HDKat6a (CAT 6 23 AWG cable) significantly
outperforms regular CAT 5 / CAT 6 cables.
We strongly recommend that you use shielded twisted pair cable.
