Pro48 Frequency Response

The Radial Pro48 is a high-performance 48V phantom powered active direct box designed spe­cifi cally for today’s higher output instruments like active basses and acoustics.

It features a digital switching power supply to signifi cantly increase headroom and directly benefi t
the user with less distortion while yielding a smooth and linear response that extends from 20Hz
to well above 100kHz for a natural and uncolored signal transfer. These combine to make the
Pro48 an ideal candidate for today’s battery powered active basses and acoustic guitars that tend
to overload other direct boxes.

The compact Pro48 is built road-ready with 14 gauge steel in our unique book-end™ design that
provides protective zones around the switches and connectors. The internal welded I-beam con­struction assures outside stress will not torque the PC board thus assuring longer product life.

Exceptional sonic performance, great natural tone at an affordable price; the Radial Pro48 truly
represents a breakthrough in value!

Pro48 Application

Just about any instrument from bass to mandolin will
benefi t from the Pro48s extended frequency response.
Instruments connect to the Pro48 and a parallel thru-put
connects to an on-stage amp. The PA or recording sys­tem is fed by the Pro48 XLR balanced mic-level output.

HEAVY-DUTY WELDED I-BEAM
enclosure of 14 gauge steel makes
it impossible to torque the PC board.
Eliminates cold solder joints.

BAKED ENAMEL fi nish for excel­lent durability and great looks for
years!

MILITARY-GRADE PCB with full
surface ground plane to reduce
susceptibility to RF noise.

SWITCHING POWER SUPPLY steps
up the current from phantom power
to produce 9 volt internal rails. With
more voltage to work with than typical
active DIs, the Pro48 produces more
headroom and dynamic range while
lowering noise.
