Know before you buy
No, the Pro48 is powered entirely by 48V phantom power from your mixing console or audio interface. You do not need batteries or an external power adapter.
Active circuitry provides higher input impedance and a stronger, cleaner signal compared to passive boxes. This is particularly beneficial for instruments with passive pickups, as it preserves the high-frequency detail and prevents signal loss over long cable runs.
Yes. The Pro48 is specifically designed to handle high-level signals without clipping or distortion, making it an excellent choice for active instruments that might overload standard direct boxes.
The Thru jack allows you to send your instrument's signal simultaneously to the direct box and your stage amplifier. This lets you monitor your sound through your own amp while sending a clean, balanced signal to the house PA or recording console.
