The COBALT C-2500 is a fully featured 2500W / 2.5kW FM Transmitter that has superior audio quality and sound clarity thanks to its 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. A backup PSU is included as standard giving you redundancy right from the start.Ideal for many Medium power Broadcast applications where High quality audio is needed.COBALT Medium Power Transmitters have an industry standard 7/8 EIA output, ready to connect to your Transmission line.Powered by single phase or 3 phase power, and protected by a breaker at the rear, its quick and easy to connect to a new or existing system. 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.An optional DC Input lets you run the COBALT C2500 on a 48V DC power system and allows the telemetry and alarms functions to still be accessible in the event of a mains power failure that opens further possibilities for off-grid power options.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.Audio monitoring is a new function that lets you stream confidence audio monitoring back to any web enabled device. Simply log in to your Cobalt Transmitter, and easily listen to audio form any source or the audio thats being processed prior to entering the PA going on-air. This is great so you can hear what your market is listening to. Change the source to the Analog, Digital or a test tone and listen to that too. Great for checking in on Audio coming in from an STL or direct out of your mixer. If you have the optional Tuner or MicroMPX in your Cobalt, those too can also be monitored.A Shoutcast / Icecast stream input is now included as standard, acting as a primary or back-up audio input.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.Main Features:Direct to Digital Synthesized modulationFCC Part 73 Certified for LPFM, and IC Certification for CanadaLinux OSRGB Screen4 Band Audio ProcessorRedundant PSUAudio monitoring for confidence purposes by web browserDynamic, UECP Compliant RDS EncoderITU-R BS412.9 LimiterDigital MPX (AES192)Ethernet Control with HTTPSSNMP v1, v2c, v3Advanced Automations and configurationsSchedulerAudio Failover and Silence DetectionBackup Audio player via USBShoutcast / Icecast Stream inputGPS Sync for SFNOPTIONSMicroMPXMicroMPX SFNTuner2wcom MOIN CODEC6 Band Audio Processor48V DC Power input (power to exciter only, no RF power is available)Specifications:Output Power (W): 2500W / 2.5kWRange (W): 2500W adjustableRF Output connector: 7/8 EIA, 50 ohmInput ACV: 208/400Vac Three phases 4763 HzTemperature controlled fan: 2Power supplies: 3 (Including one backup)Dimensions WxDxH (inch): 19 x 24 x 3RU (7)Dimensions WxDxH (cm): 48.3 x 60.0 x 13.3Weight: 24kg / 53lbMODULATORTransmitter type: Solid-state FM Stereo transmitterModulator: Direct-to-channel (DDS)RF Output Frequency Range: VHF Band II, 87-108MHzRF Frequency Steps: 100kHzFrequency Stability: 1 ppm or 150Hz in 0-50C range with internal 10MHz clock referenceFM Modulation Range Capability: 75kHz default, 100% modulation user adjustable up to 105kHz 140%), maximum 300kHzRFPower Stability: 0.25dBAsynchronous/AM noise: -60dBSynchronous AM s/n ratio: -60dBRF Harmonic and Spurious Suppression: Meets ETSI requirementsVSWR operation: Fully protected against gradual or sudden VSWR conditions.
