Arrange your video production workflow with the Roland V-1HD Portable 4 x HDMI Input Switcher. It provides connections for up to 4 HDMI inputs. These inputs have frame buffers that eliminate the need for genlocking the input sources together. You can select the input source from 1080i, 1080p, or 720p and broadcast system from 59.94 or 50 Hz. The video signals output through the HDMI ports. Of these, the first HDMI port shows the switched program output and the other works as a switcher between the program output and multi-view sources. You can apply different transitions from the included effects that include basic cuts, 4 mixes, and 30 wipes. The T-fader bar and the BP-Sync button lets you synchronize the video signal with the audio track. Other switcher controls such as transformer buttons, memory, keying, and more add variety to your video. The switcher also has sound effects like delay, compressor, and reverb along with an equalizer to modify the audio. You can remote control the switcher using the dedicated software installed on your Windows or Mac OS system. An optional MIDI connector can also be used for remote controlling the unit from a sequencer or musical instrument. This Roland audio switcher comes with an AC power adapter.
