Internet/DAB+ radio preamplifier Omnitronic EP-220NET with Bluetooth

Omnitronic EP-220NET is an Internet and DAB+ radio preamplifier with integrated Bluetooth designed as a source component for installed audio systems and PA applications. The unit receives Internet radio streams and DAB+ digital broadcasts and offers a Bluetooth input for wireless audio from mobile devices. Intended for connection ahead of power amplifiers or mixers, it provides basic front-end functionality for distributed audio systems, enabling centralized radio and streaming playback across zones.

Advantages

The EP-220NET combines multiple sources — internet radio, DAB+ and Bluetooth — in a compact preamplifier format, simplifying system design by reducing the need for separate source devices. Its tuner supports digital radio reception, while the network capability allows access to a wide range of online stations and streams. The device is built for integration with standard audio equipment, providing convenient line-level outputs and straightforward control options for installation environments.

Suitable for

• Background music and distributed audio in commercial spaces
• Public address systems requiring a radio/streaming source
• Integration into small PA rigs, conference rooms and retail venues
• Mounting in rack systems or equipment cabinets as a dedicated source unit

Key specifications

• Source types: Internet radio streams, DAB+ digital broadcasts, Bluetooth audio input
• Line-level outputs for connection to amplifiers or mixers
• Network connectivity for streaming and station access
• Compact form factor suitable for equipment racks or cabinets
• Front-end device intended for source switching and preamplification

How to use

Install the EP-220NET in the equipment rack or cabinet and connect its line-level outputs to the input channels of a power amplifier or mixer. Configure the network settings to enable Internet access for radio streams, tune to desired DAB+ stations using the built-in tuner, or pair a mobile device via Bluetooth for direct audio playback. Set output levels on the preamplifier and on downstream amplification to achieve the required sound pressure and system balance for the installation.

Usage recommendations

Place the unit where it can access the network reliably and where the DAB+ antenna receives good signal strength. Use short, balanced cables where possible for the line outputs to reduce interference. When integrating with multi-zone systems, confirm gain staging between the EP-220NET and the downstream amplifier or mixer to avoid clipping or excessive noise.
