Wireless In-Ear Monitoring System
The t.bone IEM D2.4 is a digital in-ear monitoring system that transmits stereo audio in the 2.4GHz frequency range. It uses True Diversity technology, which employs two independent antennas and receiver circuits to constantly compare incoming signals and automatically switch to the stronger one. The result is a clear, stable connection, even on busy indoor stages or in setups with many wireless systems in operation. A bright OLED display makes it easy to monitor channels, groups, and signal levels at a glance, while IR synchronisation enables quick pairing with additional receivers. An integrated limiter protects against sudden peaks, ensuring safe and consistent listening levels. With three operating modes – stereo, mono, and mixed – the IEM D2.4 adapts easily to both straightforward and complex monitoring environments.

With an impressively low latency of just 3.7ms, it ensures a perfectly natural monitoring experience, free from distracting delays – so performers can stay completely in sync with their sound. Thanks to its excellent signal-to-noise ratio, the IEM D2.4 produces clean, detailed audio with outstanding clarity and zero distortion. Designed for effortless integration, the transmitter features dual combo inputs for XLR and 1/4" jack connections, plus loop outputs for easy signal routing within larger monitoring setups. The result is a reliable, great-sounding system ready for any stage or rehearsal environment.

For pros on a budget
The t.bone IEM D2.4 is the perfect choice for musicians and performers who want pro-grade in-ear monitoring without the high price tag. Designed for semi-pro and professional users alike, it delivers reliable performance for gigging bands, touring artists, and anyone who needs consistent, accurate monitoring in any environment. Event organisers and rental companies will appreciate its scalability – up to eight systems can run simultaneously, making it easy to outfit entire groups or productions. With a receiver battery life of up to eight hours per charge, it's ready for extended performances on medium-sized stages, from theatres and musicals to live concerts. While straightforward to use, new users are encouraged to take a moment to familiarise themselves with the system's functions to make the most of its features.

About the t.bone
Since 1994, the t.bone has been one of Thomann's in-house brands, and its name can be found on devices such as headphones, wireless systems, in-ear equipment, and various microphones and matching accessories. "the t.bone" products are made exclusively by renowned companies who also manufacture products for other well-known brands. This provides a clear advantage: Brand-quality products at very reasonable prices. And word gets around: One in seven Thomann customers has already bought at least one product from the t.bone.
Ready for the road
The t.bone IEM D2.4 is built to perform on stage and on tour, delivering reliable monitoring even in demanding live setups with complex mixes – perfect for bands that need multiple monitor channels running at once. The stationary transmitter, weighing just 850g, can be easily mounted in any standard 19" rack using the rack mounting kit included here, making it a practical choice for professional touring rigs. The receiver, weighing under 100g, clips discreetly onto a belt and is barely noticeable during performances. For added reliability on the road, the system features a TNC antenna connector, which provides a secure screw-on connection (stronger and safer than traditional BNC bayonet fittings) ensuring consistent performance night after night.
