The Roland VR-3 AV Mixer is a compact video and audio production device that allows you to mix multiple channels of audio, easily switch up to four channels of live video complete with effects, and stream the output to the web via USB. 

With computer video pass-through, it"s perfect for live events that require projection of a computer screen and a simultaneous live output stream of the proceedings via web services such as Ustream, Stickam, and more.The 4.4 lb device accepts up to four composite video sources such as video cameras & DVD players as well as a computer video (VGA) source. 

A touch-screen LCD makes it easy to access the menu and monitor & switch sources as you keep track of program output.The audio inputs are just as versatile: You get four mono (XLR/TRS combination jacks) and two stereo inputs (both RCA and 3.5mm). These of course can be faded in and out easily via the VR-3"s sliders. For capturing room audio, there"s also a built-in stereo mic in the unit.

The VR-3 offers powerful effects in the realms of both sound and vision. For video, you can execute wipes and fades with the mixer, and you can even key in a green-screen-backed performer against a separate background via the transparency knob. Audio effects include reverb, EQ, and low- & high-pass filters, and there"s also delay of up to 4 seconds so you can ensure that your audio is in perfect sync with your video.The portable device is great for streaming live sports, worship events, school plays, conferences, class reunions ? you name it. An AC power adapter is included; 9V battery power is optional. The compact VR-3 AV Mixer always is ready to go.


Built-In Touch-Screen LCD for Monitoring & Source Selection

For easy video source & menu selection and monitoring, the mixer features a built-in touch-screen LCD. You can monitor four inputs and the output. The monitor can also be used to view a quad display of inputs, program out, or a combination quad view with program out. When the [INPUT] button and [OUTPUT] button are pressed simultaneously, the output picture is overlaid on a four-way split screen of the input

Composite & PC Video Inputs

Inputs 1-3 take a composite video input, while Input 4 is switchable between composite or VGA (PC video). A built-in scan converter is available for the PC input to allow it to be mixed with the other video sources. A PC loop output jack is also included, enabling direct connection to a projector or display with no reduction in resolution

Flexible Audio Mixing Options

The mixer accepts four mono (XLR or 1/4" TRS) inputs as well as two stereo audio channels, all available to be mixed via the unit"s sliders. GAIN/EQ/PAN dials enable you to improve the sound very easily. There"s also a built-in stereo microphone for capturing, mixing & recording ambient sound of the event

Video Effects

Perform simple video compositing with the VR-3. In addition to Transition (mix/wipe) effects, Picture in Picture and Split-Screen are also available. Simply select an effect and the respective video sources

Keyer for Chroma & Luma Keying

Control transparency with a single knob. Advanced video composition such as placing a person or text over a background video source (chroma/luma keying) can be fine-tuned using a single knob, for that perfect live green-screen shot

Audio Effects

Built-in digital audio effects include Noise Gate, EQ, Reverb, Noise Suppressor, Enhancer, and Master Lo/Hi Filters. Select them using the menu on the touch-screen monitor. Reverb control enables the adjustment of the sound space, while Master Lo/Hi Filters enable stable mixing for audio streaming

Live Production

Use the VR-3 for live stage production that employ a projector or large display. Show a computer image as the main display or use the composite out for a mixed image

Live Streaming via USB

The mixer is a USB video/audio device for web streaming or recording the program output to a PC/Mac. Stream the event (visuals and audio) to the internet by connecting to a computer via USB and linking to a live-streaming service (service not included)

Great for Schools, Seminars & Training Rooms

The VR-3 has the footprint of a standard sheet of paper, so it easily fits on a podium in a seminar/conference room. A signal from a PC can be sent through the VR-3 to the projector through the VGA terminal. Images from the PC (such as a web browser or PowerPoint or Keynote slides) plus a DVD or a document camera or video camera can all be switched easily

Stream Live to the Internet from the Street

The VR-3 weighs less than 5 lb, so the unit can easily be taken anywhere, at any time. Carry it with a laptop and video camera. Using an external 9V battery (not included), the unit can operate for 2 hours without AC power. Share the images from events, shopping malls, and festivals to your audience via the internet 1

Multiple Inputs for Multi-Camera Production

With multiple video inputs, you can use two or three cameras to create a great viewing experience for those watching your live stream, for events such as sports. Add a computer to the input to overlay a time clock, score, or even player stats using the mixer"s compositing feature. Powering the VR-3 via battery and hooking it up to your laptop equipped with a 3G or 4G mobile data card (all sold separately) gives you a fully portable broadcast solution that"s ready to go for any event

Audio Delay & More for Live Performance Streaming

Control audio for better sound, with built-in equalizer, noise gate, and reverb. Ensure the audio always matches the video by adjusting the audio delay (up to 4 seconds) for that perfect lip sync. Use the memory function to recall settings that were locked in during rehearsals. This enables great-sounding events even when speech and live music are alternating

Produce Events & Stream Simultaneously

The VR-3 is equipped with four video inputs and six audio inputs. It can be used flexibly in a venue with existing video cameras or PA equipment. Switched video images can be output to the PC for Internet distribution through the USB port, while using a projector or large TV monitor at the same time. Effectively produce events with video images from video cameras and a computer. Inspire people in remote locations by distributing live video images of a ceremony, reunion, or other important events
