The Pyle PDC22 is a dual-channel passive direct‐injection (DI) audio box designed to convert unbalanced ¼″ instrument or line signals into balanced XLR outputs for mixers or PA systems. It features two high-quality direct boxes in one steel enclosure, switchable input attenuation (0 dB, -20 dB, -40 dB), a parallel “link” output for continuing the unbalanced signal to an on-stage amp or monitor, a balanced XLR output for long-cable use, and a ground-lift switch to eliminate hum and buzz from ground loops.
