The Clear Com Portable Main Station is a 2-channel stage production intercom. Separate A/B channels allow for separation of house and stage communications. The CS-210 has three XLR outputs for each channel. Use program input to feed audio to technicians or backstage areas. A "stage announce" output can be fed to the PA during rehearsals. Large pushbuttons allow channel access and easy to adjust sidetone control reduces noisy transmissions.
