1 1/2 ME Analog Switcher with 8 to 12 inputs and 2 Keyers

Model Details

The Echolab Prima MVS3 is an analog switcher designed for small to mid-sized installations that need an easy-to-understand, easy-to-operate control panel. The MVS3 makes studio quality very affordable. It offers 8 to 12 inputs, 11/2 M/E's and 2 keyers. Complex effects are created on the full M/E, and the panel provides take controls for easy dissolves or wipes between program and preview. The downstream keyer allows a second level of key to be mixed over the program output.
