V-1HD⁺: HD Video Switcher - Switch, Mix, and Create Like a Pro
Say Goodbye to Workflow Workarounds
While many video switchers promise easy workflows, they often require workarounds for optimum results. Too often, those workarounds force you into technical compromises and purchasing extra gear. With its feature-rich design, the V-1HD
+
provides the key tools you need to get the job done right.
A Legacy of Success
Since its release in 2015, the Roland V-1HD has been the most popular high-definition, four-channel HDMI video switcher available. The V-1HD
+
extends this legacy with a deeper feature set for advanced applications—while still maintaining the simple operation, pro performance, and rugged reliability that’s made the V-1HD a favorite of users around the world.
No-Compromise Video I/O
Video professionals shouldn't be forced into making technical compromises. With its full-featured video I/O, the V-1HD
+
is inspired by your need to do more.
Four Video Inputs and Onboard Scaling
Four HDMI inputs with frame rate conversion let you mix a variety of sources, including cameras, presentation computers, tablets, and video game consoles. And when you have a troublesome source that won’t display correctly, simply plug it into Input 4 and let the built-in video scaler sync and calibrate the image automatically.
Two Video Outputs
Two independent HDMI outputs can be assigned to display one of three different video busses, providing the versatility you need for pro production. For example, you can use one as your main program output for a recorder or livestream, and the second output to turn any HD video monitor into an “up-next” input preview display or expanded multiviewer with 10 windows.
Pro Operation Made Easy
Your passion for a simplified interface led our designers to add quick-action buttons for the most commonly used operations. With one-touch access to the system menu, downstream key on/off, transition type, picture-in-picture, effects on/off, and more, V-1HD
+
production workflow is smooth and hassle-free.
The V-1HD
+
also includes PGM and PST busses and a transition/fade bar, which are the most-recognized video switching controls in the industry—and the quickest for beginners and volunteers to learn. And with tactile audio volume knobs, signal/peak lights, and unity gain markers, it’s simple and intuitive to adjust sound levels on the fly.
14-Channel Audio Mixing with Effects
The V-1HD
+
allows a single operator to do more than switch cameras—they can mix professional sound too. The integrated 14-channel digital audio mixer blends HDMI audio with mic and line sources, and also offers a variety of onboard effects to sweeten mixes.
Audio Inputs
With two XLR mic inputs and selectable phantom power, the V-1HD
+
lets you bring pro-grade microphones into your productions, including condenser broadcast mics. There’s also an 1/8-inch input for a lavalier mic or stereo audio source like a smartphone, plus another stereo input on RCA jacks. Embedded stereo audio from the four HDMI inputs can be included in your mix as well.
Audio Outputs
With the V-1HD
+
, there’s no need for a dedicated small audio console. Distribute analog sound to a PA system via two balanced ¼-inch TRS outputs, and use embedded digital audio in the HDMI outputs to feed recorders and livestream broadcasts.
Audio Effects
Leave the outboard gear in the recording studio—each audio input on the V-1HD
+
has its own three-band equalizer, high-pass filter, compressor, and noise gate, plus a sync delay to align audio with video if needed. The XLR and 1/8-inch inputs also include de-essers to clean up vocal sounds in real time. And with the limiter, three-band equalizer and compressor on the main outputs, you can deliver broadcast-quality sound every time.
Production-Critical Signal Monitoring
Without proper signal monitoring, you’re running blind. The V-1HD
+
incorporates several real-time monitoring tools that make it easy to keep your productions looking and sounding their best.
Multiviewer Display
A 10-window multiviewer display can be applied to one or both HDMI outputs, helping you manage productions in real time. Cue up camera shots, preview presentations, and choose stored still images before taking them live to the program feed. Camcorder recording status can be monitored as well.
Audio Monitoring
Even if your video looks perfect, poor sound will ruin the entire production. With the V-1HD
+
, you can always keep track of your audio quality. Each analog input has its own signal/peak indicator, and headphones can be plugged in to monitor the overall audio feed. When using the multiviewer display, signal level meters are shown for all inputs and the main outputs.
Effects, Keying, and Stills
The powerful effects engine in the V-1HD
+
keeps audiences engaged with visually appealing content while opening new revenue streams for customer graphics creation.
Four-Layer Effects Engine
Savvy visual storytellers understand the power of layered graphics and visual effects. With four composition layers at your command, it’s simple to add lower-third titles, logos, social media comments, and more to inform your audience and keep them involved.
