About the Proel DB1A

The Proel DB1A single-channel, top-of-the-range active DI BOX has been designed to fit into the most demanding setups and applications with an outstanding performance. It includes an MU-METAL core transformer able to reduce phase and harmonic distortion to a minimum, with noticeable improvement of the linear phase even on very long cables.

The audio integrity is guaranteed by low-noise, low-consumption IC for balancing the signal, able to handle very low-impedance loads. The input section features JACK and XLR connectors with link possibility and a PAD of up to 30 dB that permits very high-level signal inputs to be used.
