VR4HD HD AV Mixer 4Ch with HDMI in/out & Touch Multi-Viewer

VR-4HD All-in-one High-Definition Professional AV Mixer

The VR-4HD is a complete HD studio in a compact and portable package that replaces several different pieces of complex A/ V equipment.

Designed with single-person operation in mind, the VR-4HD enables easy switching and mixing of sound and video using advanced video and audio Digital Signal Processing (DSP) along with dedicated hardware controls faders, buttons and touch screen interface. It beautifully integrates a digital audio mixer, video switcher, multi-viewer touch screen and USB video/audio streaming interface into a stand-alone device. This portable live HD production solution is ideal for schools, churches, council meetings, corporate events, sports, training sessions, or any other live event.

Easy operation for professional results

The VR-4HD features professional quality broadcast controls and switches ensuring more accurate and faster operation than interfaces based on a computer style mouse and keyboard. The ability to simultaneously switch video with the push of a button and adjust audio with the push of a fader is invaluable and puts all essential features at the operator’s fingertips. The built-in multi-view screen is also a touch screen interface for accessing set-up parameters, making it extremely easy to adjust picture-in-picture settings by dragging the inset window onto the screen.

Support for today and yesterday’s video sources

The VR-4HD has three dedicated HDMI input connectors compatible with a variety of equipment and support 1080p/1080i/720p video resolution. The fourth input includes a scaler to support both video and computer resolutions and also supports analog RGB and component input so older devices can be used as sources without the need for external conversion equipment.

Both progressive and interlace signals can be input allowing for both 1080i and 1080p signals to be used at the same time. Video signals input from a PC are accurately displayed thanks to progressive signal processing. HDCP is supported for input of copy protected content from devices such as Blu-ray disc players.

Compositing effects

The VR-4HD includes DSK (Downstream Keying), Picture-in-Picture (PinP), Split and Quad composting effects ideal for creating news style broadcasts and corporate presentation content.

The DSK function is great for overlaying titles, song lyrics or logos onto incoming video sources that can be switched in the background while text or images remain displayed.The DSK supports both Luminance Keying (Black / White) and Chroma Keying (Blue / Green) for compositing two videos in one screen using Picture-in-Picture, or for using the split function – ideal for seminars and presentations.

Great video needs great audio

Achieving great sounding audio for video productions is easy with the VR-4HD which features Roland’s award winning digital signal processing and advanced features including auto-mixing, echo cancel and delay for perfect lip-sync between audio and video. The VR-4HD’s audio mixer can mix the four XLR microphone inputs, stereo RCA and 1/8 mini connector along with the audio embedded in the four HDMI inputs. The final mix can be output via XLR, RCA and also embedded into the HDMI ouput.

A unique loop-back audio capability is included with the USB 3.0 port that can bring in audio from a connected PC using a conferencing software, such as Skype, and return audio to the PC without any howling or echo thanks to the included Echo Cancelation feature. This makes the VR-4HD an ideal web conferencing tool that allows for multiple video and audio sources to be used with free online webconference softwares.

The included Auto-Mixing function makes mixing multiple speakers at conferences and panels simple and easy by automatically managing the levels of the microphones across the multiple people speaking. and can even give priority for volume Volume priority can be assigned to an event moderator who can always be heard above the other participants.
