| Feature | ART PDB4 Four | Others |
|---|---|---|
| Channel Isolation | Transformer-isolated channels prevent ground loops, ensuring hum-free audio. | Most Indian DI boxes have basic ground lift, less effective for complex ground issues. |
| Number of Channels | Four fully isolated channels support multi-instrument setups. | Many local DI boxes offer 1-2 channels, limiting multi-source use. |
| Attenuation Switches | Switchable attenuation (0dB, -20dB, -40dB) for precise level matching. | Most Indian models lack switchable attenuation, risking distortion. |
| Build & Durability | Rack-mount, roadworthy design for touring and studio use. | Many local DI boxes are portable but less rugged for frequent touring. |
