CARACTERÍSTICAS PRINCIPAIS:
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
