Heritage Audio is excited to introduce the new P DI Series: the P DI ONE (single channel) and P DI 2 (dual channel). These high-quality custom-made transformer-equipped passive DI boxes are designed for exceptional studio recording and live performance.
While passive DI boxes are often viewed as simple adapters, we consider them as essential tools for showcasing your audio output. Just like a clean, transparent storefront window highlights the quality of the products inside, our DI boxes are designed to seamlessly blend into your setup. Drawing from 15 years of research and development, our team has created DI boxes that prioritize performance without drawing unnecessary attention.
Transformers play a crucial role in high-level passive DI boxes, and our expertise in designing custom transformers shines through in the HA-DI model. By carefully selecting alloys and fine-tuning the response, we have crafted a nickel core transformer with MU Metal shielding. This combination ensures ultra-transparent signal transfer while guarding against unwanted noise and interference.
The success of the P DI ONE and P DI 2 builds on Heritage Audio's track record in transparent passive signal handling. After years of perfecting our design with the R.A.M monitor controller series, we have applied our knowledge to create DI boxes that seamlessly convert high impedance to low impedance and balance audio signals. The result is a clean, distortion-free sound that preserves the original tone of your instrument.
With its power-free, passive design, the P DI ONE and P DI 2 effectively eliminate ground loop hum and buzz while maintaining the integrity of your sound. Rest assured that like all Heritage Audio products, these DI boxes are built to last and offer exceptional value for your studio or live performance setup.
