The TechniSat VIOLA 231 OD is a heavy-duty, ultra-robust portable DAB+/FM digital radio engineered specifically for construction sites, demanding workshops, outdoor gardening, and remote recreation. Built to survive challenging environments, this high-performance site speaker features a rugged, impact-absorbing chassis with an IPX4 splash-proof rating to protect the internal electronics from rain, water sprays, and dusty conditions. It is a premier choice for trade professionals and passionate DIY enthusiasts who require reliable, crystal-clear audio during intensive physical work.
One of the standout features of the VIOLA 231 OD is its integrated, interchangeable battery docking mount located on the back panel. This dock is fully compatible with standard Makita 18V slide-on power tool batteries (up to a maximum battery height of 80 mm), allowing you to power your work day using your existing workshop batteries. When standard mains power is accessible, the radio can also be powered continuously using the included 230V AC adapter. Audio delivery is powerful and clean, driven by high-quality stereo speakers delivering a massive 30W RMS total system power (2 x 15W) that easily cuts through loud machinery and outdoor ambient noise.
For modern media playback, the VIOLA 231 OD features integrated Bluetooth 5.0 (supporting A2DP and AVRCP profiles), allowing you to wirelessly stream personal playlists, podcasts, or radio apps directly from your smartphone or tablet with full control from your mobile device. Traditionalists will enjoy the high-sensitivity telescopic antenna that pulls in static-free digital DAB+ and analog FM with RDS, supported by a 40-station favorites memory bank (20 DAB+ / 20 FM). Navigating your media is seamless thanks to a vibrant 2.4-inch color TFT display that supports adjustable brightness levels, slideshow graphics, and catSLS program metadata.
For wired external media, the radio is equipped with an analog AUX-IN input and a dedicated 3.5 mm headphone output for private listening. Useful utility functions like an auto-off sleep timer and a built-in alarm clock (operational when connected to AC mains power) add to its versatility. Complete with a comfortable integrated carry handle and weighing in at a solid 2.27 kg, the TechniSat VIOLA 231 OD is a highly dependable and mobile sound system designed to keep pace with the hardest working days.
