Kramer VP-771 (70-710230140)

The Kramer VP-771 is a high-quality presentation switcher and scaler for a variety of signals. It accepts one of nine inputs: component video, DisplayPort (DP), 3G HD-SDI, two computer graphics, two composite video and two HDMI signals. It scales the video, embeds the audio, and outputs the signal to one HDMI, one computer graphics, one 3G HD-SDI and one DGKat TP, together with digital audio, unbalanced stereo and a 2x10-watt amplified balanced stereo speaker output.

Kramer VP-771 Key Features

  • K-IIT XL™ Picture-in-Picture Image Insertion Technology — Ultra-stable picture-in-picture, picture-and-picture, and split screen capability. Any video source can be inserted into or positioned next to any other video source with full window positioning and sizing controls.
  • Kramer's PixPerfect Scaling Technology — Kramer's precision pixel mapping and high quality scaling technology. High-quality 3:2 and 2:2 pull down de-interlacing and full up and down scaling of all video input signals.
  • 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.
  • Advanced Deinterlacing Functions — Method, sync, selectable film modes, diagonal correction and motion detection sensitivity, 3:2 and 2:2 pull-down; 24sf handling.
  • HDTV Compatible.
  • 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.
  • Multi-Standard Operation — SDI (SMPTE 259M and SMPTE 344M), HD-SDI (SMPTE 292M) and 3G HD-SDI (SMPTE 424M).
  • Advanced Input and Output EDID Management.
  • Mass Notification Emergency Communication System (MNEC) — Activates a national or campus-wide notification, immediately displayed when an emergency situation develops. It uses automatic text overlaying, either via a crawler or a full screen cover up, as well as an optional audio alert.
  • DGKat™ Signal Integration — Kramer's unique technology for converting TMDS as well as control and communication to signals that run over twisted pair cables.
  • System Range — Up to 90m (295ft) at 1080i @60hz or up to 70m (230ft) at 1080p @ 60hz when using Kramer DGKat cables.
  • Note: Transmission range depends on the signal resolution, graphics card and display used. If using third-party shielded CAT cables, both ends of the shield must be soldered to the connectors for the products to function properly.
  • Video Inputs — Component (Y, Pb, Pr) video on RCA connectors, DisplayPort (DP), SD/HD/3G HD-SDI (including SDI loop) on BNC connectors, 2 computer graphics on 15-pin HD connectors, 2 composite video on RCA connectors and 2 HDMI.
  • Scaled Outputs — HDMI, computer graphics on a 15-pin HD connector, SD/HD/3G HD-SDI on a BNC connector and DGKat twisted pair on an RJ-45 connector.
  • SDI Channeling — Select one active signal and three bypassed signals from eight embedded stereo audio channels.
  • Multiple Output Resolutions — Up to 2K and 1080p.
  • HDMI Deep colour Support.
  • Luma Keying — Via PIP window.
  • Vertical Keystoning.
  • Built-in ProcAmp — colour, sharpness, contrast, brightness and gamma are set individually for each input.
  • 3D Comb Filtering — Provides the best quality colour separation for composite video inputs.
  • Built-in Time Base Corrector — Stabilizes unstable video sources.
  • Powerful Noise Reduction Filters — Temporal, block, mosquito and combing.
  • Picture Zooming — Both on main and PIP window from 100% to 1600%, including separate V and H sharpness control.
  • Multiple Aspect Ratio Selections — Follow input, follow output, best fit, letterbox and overscan.
  • Dual Window Display — Preset picture-in-picture, picture-and-picture and split screens, as well as customized window layouts.
  • Audio Inputs — 2 HDMI, 2 computer graphics and 1 DisplayPort and 1 microphone in on 3.5mm mini jacks; 2 CV and 1 S/PDIF on RCA connectors.
  • Audio Outputs — 1 S/PDIF on an RCA connector, 1 unbalanced stereo audio on a 3-pin terminal block connector.
  • Built-in Audio Power Amplifier — 10W per channel audio amplifier with speaker outputs.
  • HDMI Audio — Embeds/de-embeds HDMI audio with delay of 0-90msec for lip-sync correction.
  • Microphone Input — Supports mix and talk-over features, as well as 0-90msec delay to prevent feedback.
  • Non-Volatile Memory — Saves final settings.
  • Firmware Upgrades — Via Ethernet and RS-232.
  • Multiple Control Options — Front panel buttons, contact closure, OSD (on-screen display) via front panel buttons or IR remote (remote control included), Control Application software for use via Ethernet and RS-232.
