VP−551X is a versatile, professional presentation
scaler/switcher for 4K@60 (4:4:4) HDMI, VGA and
composite video signals. The unit scales the video
and provides options to use the embedded HDMI
audio or to select the companion audio channel from
one of ten analog audio input signals. After processing
and scaling, the embedded AV signal is sent to the
HDMI and the HDBaseT outputs simultaneously, and
the audio is also sent to a balanced stereo audio
output, S/PDIF digital output and a pair of
loudspeakers
FEATURES
High-Performance Switcher/Scaler-Scales HDMI, VGA and Composite video signals for output to
two mirrored outputs: HDMI and HDBaseT. Constant output sync prevents signal disruption when
switching between inputs and when no video is detected
High-Resolution Video-Supports and scales to/from resolutions up to 4K@60Hz (4:4:4) on the HDMI
inputs and output, and 4K@60Hz (4:2:0) on the HDBaseT output. Complies with HDCP 2.2. Supports
HDR10, CEC, xvYCC color (on input), Dolby TrueHD/DTS−HD Master Audio (by−pass), as specified
in HDMI 2.0
Professional Video Quality-Provides selectable aspect ratios (full, best fit, over scan, under scan,
letter box and pan scan). Includes built–in ProcAmp for color, hue, sharpness, noise, contrast and
brightness control. Supports PixPerfect™, Kramer’s precision pixel mapping and high–quality scaling
technology. High–quality 3:2 and 2:2 pull−down de−interlacing and full up−scaling and down−scaling
of all video input signals
Versatile Audio Options-Includes a companion analog audio input for each of the 10 video inputs,
enabling the user to embed a separate analog audio channel into each video signal or to bypass an
embedded audio input (for example, to support multi−channel, compressed audio formats like Dolby
and DTS). Provides 2 independent microphone inputs on 6.3mm connectors (each with optional 48V
phantom power) for mixing, switching or talk−over. On the output, besides the audio embedded on
HDMI and HDBaseT outputs, the audio signal is also extracted (de−embedded) and output as
balanced stereo analog audio, and as digital audio through an S/PDIF connected device, as well as
amplified to 20W per channel for connection to loudspeakers
Powerful Audio Features-Includes DSP with audio equalization, mixing, delay and more
Versatile Powering Options-Receives power from a universal power supply (100–240V AC) and
provides PoE power to a compatible HDBaseT device
HDTV Compatible
4K and Legacy Inputs-8 4K@60 (4:4:4) HDMI inputs, 1 VGA input, and 1 CV (composite video) input
Non-Volatile Memory-Saves final settings before shutdown and retains them for next power up
Convenient Control Options-Local control via front panel buttons (input selection, audio mute,
freeze and front panel lock), RS–232, IR remote, and OSD. Long−distance control via Ethernet using
embedded web pages
Easy Installation-19” enclosure for rack mounting a unit in a 1U rack space with included rack ears
and universal 100–240V AC power connection
