The RTS MS-4002 is a complete four-channel, balanced audio master station and 4 amp system power supply in a single unit. You simply plug it into any AC power outlet from 100 to 240 volts, add a microphone or headset, connect intercom stations to the back panel, and you are ready to communicate. The MS-4002 is now equipped with an advanced programming mode on the front panel, eliminating the need for internal DIP switches. It also has a feature that automatically senses the type of headset attached to the unit, either dynamic or electret. The MS-4002 fits in a standard 19" equipment rack and is 1 rack unit high. The MS-4002 is Clear-Com compatible, with the ability to run in unbalanced mode.
