Aqua Broadcast Cobalt C‑30 30W Digital FM Transmitter

Aqua Cobalt C-30 is a 30W direct-to-channel digital FM transmitter with DDS exciter, stereo encoder, AES/EBU, MPX, dynamic RDS, SFN sync and 4‑band processing for low-power broadcast and exciter use.

Product Overview

Цей Aqua Cobalt C-30 is a robust 30W digital FM broadcast transmitter designed for LPFM, community stations, drive-in events and as a high-quality exciter for larger amplifier chains. Direct-to-channel DDS modulation running on a customised Linux OS delivers exceptionally clean audio and tight RF stability, while the built‑in stereo encoder, dynamic RDS generator and 4‑band audio processor provide a complete on-air solution in a compact 1U chassis. With analogue stereo, AES/EBU and digital MPX inputs plus Ethernet, USB, GPIO and GPS sync, the Aqua Cobalt C-30 integrates easily into both traditional and AoIP-based facilities.

Aqua Cobalt C-30 Основні характеристики

    • 30W solid-state FM stereo transmitter using direct-to-channel DDS modulation for low distortion and excellent spectral performance.
    • Adjustable RF output typically from 5–30W with N-type RF connector, high AC efficiency and low power consumption.
    • VHF Band II operation from 87–108MHz with 100kHz steps and ±1ppm frequency stability from an internal 10MHz reference.
    • Integrated stereo encoder and fully dynamic RDS/RDS2/RBDS generator supporting ASCII, UECP and multi-port Ethernet/USB control.
    • Analogue stereo audio, AES/EBU digital audio and digital MPX (AES192) inputs, plus wideband analogue/digital MPX I/O on BNC for external processors.
    • Onboard multi-band audio processor (4‑ or 6‑band depending on options) with bass enhancement, ITU‑R BS412 limiter and loudness presets.
    • GPS sync and SFN-ready operation with scheduler, automation, audio failover, silence detection and USB backup audio player.
    • Remote management via secure HTTPS web interface, SNMP v1/v2c/v3, email alerts and intelligent GPIO for full off‑site monitoring and control.
    • Mono frequency response 20Hz–15kHz ±0.02dB, mono SNR ≥75dB (AES/EBU) and mono THD+N down to 0.001% on digital input.

Applications

Use the Aqua Cobalt C-30 as the main transmitter for LPFM, community or campus stations, for drive-in cinemas and sporting events, or as a clean exciter driving external RF amplifiers. Its combination of DDS exciter, integrated processing, dynamic RDS and SFN-ready GPS sync makes the Aqua Cobalt C-30 an excellent choice wherever 30W output, premium audio quality and reliable remote control are required in a compact 1U package.
