Get to know them!

The Radial Pro48 is a high-performance 48V phantom powered active direct box designed specifically for low-volume instruments with passive pickups. The Pro48's innovative digital switching power supply significantly increases headroom and allows for less distortion while yielding a smooth, linear response extending from 20Hz to well above 100kHz resulting in natural, uncolored signal transfer. This superior performance makes the Pro48 an ideal candidate for use with low-output instruments that require extra amplification. The compact Pro48 is built road-ready with 14 gauge steel in Radial's 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. The Pro48 is designed for high-use applications wherever an active direct box is called for. A -15dB pad switch is provided to tame hot signal and expands the range of instrument preamps and the ground lift switch helps eliminate hum and buzz problems caused by ground loops. With exceptional sonic performance, great natural tone at an affordable price, the Radial Pro48 truly represents a breakthrough in value!

Radial Pro48 Features:
  • High-resolution Compact Active Direct Box with 48v Phantom power
  • Increased dynamic range and headroom
  • Compact, rugged book-end design with 14-gauge steel welded I-beam construction
  • Ideal for low-output, passive guitars and basses
  • -15dB Pad accommodates high-output sources
  • 20Hz to 100kHz Frequency Response
What is Certified Open Box Gear?

At Sweetwater, we're so picky that what we call "Certified Open Box" is actually better than what most music retailers sell as "new" gear! Our gear hasn't endured hundreds of people a week plunking away at all the keyboards, fumbling through Stairway to Heaven on every guitar or playing with every fader and knob on a mixer or control surface.

Certified Open Box (also known as a demo) means we’ve had it out of the box for our YouTube channel, displayed at events, tested in our studio, or maybe it was in a customer’s hands for a few days and isn’t ‘factory fresh’ as a result. Every Certified Open Box item we sell has Sweetwater’s 2-year Total Confidence Coverage™ warranty and has been tested and verified up to ‘new’ specs by our factory-authorized technicians to make sure it’s in perfect working order before we ship it to you.

When you buy a Certified Open Box item at Sweetwater, you get:
  • 2-year Total Confidence Coverage Warranty™!
  • Products inspected and tested by our factory-authorized techs, guaranteed to function like new (or better)!
  • FREE shipping on most items
  • Equipment that will MEET or EXCEED your expectations!

Select manufacturers may require that only the manufacturer’s products qualify towards the minimum purchase amount needed to be eligible for promotional financing. Otherwise, an invoice that meets the minimum purchase amount and contains at least one qualifying manufacturer product is eligible for promotional financing. No interest will be charged on promo purchase balance, and equal monthly payments are required on promo purchase until it is paid in full. The payments equal the amount financed divided by the number of months in the promo period, rounded up to the next whole dollar. These payments may be higher than the payments that would be required if this purchase was a non-promo purchase. During the last month(s) of the promo period the required monthly payment may be reduced due to the prior months’ rounding. Regular account terms apply to non-promo purchases. New Accounts as of 07/31/2025: Purchase APR is 34.99%. Penalty APR is 39.99%. Min Interest Charge is $2. Existing cardholders: See your credit card agreement terms. Subject to credit approval.

The estimated required monthly payment shown which excludes taxes and delivery equals the amount financed divided by the number of months in the promo period, rounded up to the next cent. During the last month(s) of the promo period the required monthly payment may be reduced due to this rounding. These payments apply only with the financing offer shown. If you make these payments by the due date each month, you should pay off this amount financed within the promo period, if it is the only balance you are paying off. If you have other balances on your account, this payment will be added to any other minimum monthly payments.
