Aqua Broadcast Cobalt C-1000 FM Transmitter

Digital FM Transmitter 1000 watt with DDS Exciter, Stereo Encoder, Analog Audio Inputs, AES/EBU, MPX, Dynamic RDS, SFN s

Perfect for applications like smaller Transmitter sites Community and College radio, or as an Exciter where High quality audio is needed.

The COBALT C-1000 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.

Radio market beating sound will let you stand out to your listeners, with it's built-in 4 band Audio Processor with Bass enhancement, Pilot protection, Wide AGC and a whole bunch of expertly designed modern presets, so you sound great right from the start.

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 its class.
