Perfect for low-power applications like smaller Transmitter sites, use as an Exciter or as a Gap-filler, Sporting where low power, and High quality audio are needed.
The COBALT C-30 Transmitter has a superior audio quality and sound clarity thanks to it‘s Direct to Channel Digital technology.
Running on a fully customised LINUX OS system, this low distortion modulator is available on all models within the COBALT family of FM Transmitters. Inputs and outputs include Analog, AES/EBU, Digital MPX (AES192), Ethernet, USB, GPIO, GPS Sync with built in SFN capabilities.
The modern design lets you easily read the Ultra-clear RGB display, and the intuitive Joystick controls with Haptic feedback and additional silicon buttons allows fast setup, getting you on the air even faster.
The advanced communication package with Intuitive web interface and remote control via Ethernet (https) lets you make changes or monitor the COBALT Transmitter. Full SNMP Version 3 management and the ability to send emails, alerts and monitor audio remotely gives you added confidence knowing you have full control from anywhere in the world on any device with a Web browser.
Easy access to all components and software controlled variable fan speed, will guarantee you low cost of maintenance . The highest AC efficiency, a compact design and reduced weight mean low cost of transportation and far the lowest total cost of ownership in it‘s class.
