Aqua Broadcast Cobalt C-5000 FM Transmitter 5000 Watt
When you need a medium power FM transmitter that is packed with standard features, the COBALT C-5000 sets new standards for compact transmitters. Perfect for all broadcast applications when high quality audio is required. The COBALT C-5000 is a full-featured FM transmitter with superior sound quality and clear sound thanks to the Direct to Channel function
Digital technology (DDS). This low distortion modulator runs on a fully custom LINUX OS system and is available to everyone
models within the COBALT family of FM transmitters. Inputs and outputs are analog, AES/EBU, digital MPX (AES192), Ethernet, USB, GPIO, GPS Sync with built-in SFN capabilities.
The compact 4RU form factor features power supplies that are hot-swappable from the front panel. Externally mounted fans and filters can also be replaced on a hot-swap basis, keeping you up and running without any downtime.
The throbbing sound of the radio market makes you stand out to your listeners, with the built-in 4-band audio processor with bass enhancement, pilot protection, wide AGC and a bunch of expertly designed modern presets, so you'll sound great right from the start.
The modern design makes it easy to read the ultra-bright RGB display and intuitive joystick controls with haptic feedback. Additional silicone buttons enable quick setup, getting you airborne even faster.
The advanced communication package with intuitive web interface and remote operation via Ethernet (https) allows the COBALT transmitter to be changed or monitored. Full control of SNMP version 3 and the ability to receive emails, alerts and remotely monitor audio gives you added confidence in the knowledge that you have complete control from anywhere in the world on any device with a web browser.
Easy access to all components and software controlled variable fan speed guarantee you low maintenance costs. The
highest AC efficiency, compact design and reduced weight provide low transportation costs and by far the lowest total cost of ownership in its class.
3kW Medium Power in a Compact Size COBALT Medium Power Transmitters feature an industry standard 7/8" EIA output, ready to plug into your Transmisison line.
Powered by a 3-phase supply and protected by a rear circuit breaker, it is quick and easy to connect to a new or existing system.
Common Connections COBALT Medium Power transmitters are designed for durability and reliability with features such as redundant fans and hot-swap power supplies. The compact design also includes easily accessible, washable air filters on the front panels of the power supplies
