Aqua Broadcast Cobalt C-1000 FM Transmitter 1 KiloWatt / 1000 Watts
Ideal for many broadcast applications as a stand-alone transmitter, or even as an Exciter for larger amplifiers where High quality audio is needed.
The COBALT C-1000 is a fully featured FM Transmitter that has superior audio quality and sound clarity thanks to it‘s Direct to Channel Digital technology (DDS). Running on a fully customized 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.

Inputs and outputs include Analog, AES/EBU, Digital MPX (AES192), Ethernet, USB, GPIO, GPS Sync with built in SFN capabilities.
An optional DC Input lets you run the COBALT C-1000 on a 48V DC power system and opens further possibilities for off-grid power options. A second PSU can also be specified giving you two independent power inputs in parallel, giving you further confidence that you have a backup Power supply, ready to allow seamless switching if a Power supply id to ever suffer a fault.
Radio market beating sound will let you stand out to your listeners, with its 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.
