Core Advantages & Applications
OT-1 Transformer: Guarantee of Pure Tone
At the heart of the DI100 is Behringer's acclaimed OT-1 output transformer. It ensures an extremely flat frequency response without coloring or distorting your original tone, while providing superior electrical isolation to eliminate annoying hum and noise caused by ground loops.
Extreme Signal Handling Capability
Built-in switchable input attenuation pads allow for input levels up to +50 dB. This means you can connect not only standard instruments but also connect the speaker output of a guitar amplifier directly to the DI100, sending the signal safely to the mixer without worrying about overload distortion.
Tank-Like Rugged Construction
Built for life on the road, the DI100 features an ultra-rugged aluminum body encased in thick, oversized rubber corners. This design not only protects against drops and impacts but also allows multiple DI100 units to be stacked securely, saving stage space and keeping setups tidy.
