Overview

Aqua Broadcast, Cobalt C-10, 10 Watt FM Transmitter

The COBALT C-10 is a robust 10W FM Broadcast Transmitter, boasting FCC part 73 LPFM and IC certifi cations. Its exceptional audio quality and clear sound from the Direct to Channel Digital technology with minimal  manipulation, maintains audio integrity. Operating on a fully customized LINUX OS system, this transmitter features a low-distortion modulator available across all COBALT FM Transmitter models. Input and output options include Analog, AES/EBU, Digital MPX (AES192), Ethernet, USB, GPIO, GPS Sync with built-in SFN capabilities. Tailored for applications like Community Radio Gap-filling and scenarios, or as an exciter requiring high-quality audio, the COBALT C-10 ensures market-leading sound. It comes equipped with a built-in 4-band Audio Processor, featuring Bass enhancement, Pilot protection, Wide AGC, and a range of expertly designed modern presets for an impressive start.

The modern design with its Ultra-clear RGB display and Intuitive Joystick controls with Haptic feedback and silicon buttons allow for swift setup, ensuring you get on the air in no time. The advanced communication package includes an intuitive web interface and remote control via Ethernet (https). Full SNMP v1, v2c, and v3 management, with the ability to send emails, alerts, and remotely monitor audio, provide confi dence with global control from any device
with a web browser.
