DRM+ Transmitters
OMB Broadcast DRM+ transmitters are designed to operate in the VHF band from 87.5 to 108MHz, fully leveraging the capabilities of this digital technology. They enable the transmission of high-quality audio and multimedia services within channels as narrow as 100KHz. Thanks to their advanced audio compression (such as xHE-AAC) and a robust transmission system (COFDM with error correction), OMB devices ensure a clear and stable signal even at low bitrates and reduced power levels.The combination of DRM+ technology and our long-standing experience translate into a more efficient broadcasting in terms of spectrum use and energy consumption, leading to a significant reduction in operating costs. Additionally, these transmitters support complementary digital services such as text, real-time news feeds (Journaline), electronic program guides, images and emergency alerts, enhancing listeners' experience and opening new opportunities for broadcasters.With strong resistance to interference and signal degradation, our DRM+ transmitters are ideal for both fixed and mobile reception, ensuring reliable, high-quality coverage at all times.
