HQUltra770ASV is a universal live events scaler-switcher & LED videowall image scaler based on Calibre’s proprietary class-leading HQUltra 4K image processing technology and includes a direct H.264 1080p streaming video input capability over its standard gigabit ethernet port.


Calibre’s HQUltra 4K scaling provides best in class picture quality with low latency video processing. Featuring Calibre’s proprietary HQUltraFast input channel switching able to switch input channels in under half a second, HQUltra770ASV has a wide range of input connectivity for today’s digitally connected ProAV world, but still is able to support legacy formats too, all with great image quality.


HQUltra770ASV includes stereo analogue audio inputs and outputs with audiofollow-video capability. There are two microphone inputs with phantom power available and internal mixer for talk-over. The internal power amplifier provides 2x15W RMS to directly drive loudspeakers in meeting rooms and smaller conference room, plus line level balanced stereo outputs to drive an external amplifier or powered loudspeakers, HQUltra770ASV includes front panel controls with easy to read front panel menu system as well as remote control via inbuilt webserver or easy to implement protocol.


For in-camera use a Genlock input is provided compatible with bi or tri-level sync or black & burst. For LED videowalls HQUltra770ASV has a special LED mode with per-edge pixelaccurate image sizing for fast pixel-perfect image alignment on LED videowalls.
