Radial J48 Backline Rental for Live Performance
Active Direct Box
Radial J48 is selected for a defined job in the stage signal path. Source type, input and output format, channel count, power requirements and destination are documented so the correct device reaches the correct position.
Available subject to production date, location, rider requirements and prior reservation.

Artist Perspective
Why professionals request this model
Radial J48 is requested when the player or production depends on its input (1/4 in), output (Balanced XLR), and circuit (Active 48 V phantom powered). Rider review identifies which characteristics are performance-critical before the model is allocated.
Model Characteristics
How it differs and how it can be configured
Radial J48 is distinguished by its input (1/4 in), output (Balanced XLR), and circuit (Active 48 V phantom powered). A proposed substitute must preserve the characteristics that affect playing response, connection and stage use rather than only matching the broad equipment category.
Production Fit
Where it works best
Radial J48 suits stage positions where its specific conversion, isolation, switching or routing function has been identified during the technical advance.
Preparation
Specific preparation checks
Radial J48 is signal-tested through every required channel and connector. Power, isolation, switching, routing and the destination device are verified against the stage input plan.
Rider Review
Likely rider alternatives
Alternatives should perform the same signal, isolation, conversion or switching role with compatible connectors, channel count and power requirements.
