Radial Engineering Ltd.
Power-1 Owner’s Manual
INTRODUCTION
The Radial Power-1 rackmount power supply and surge suppressor gives musicians, engineers, producers,
studio owners, commercial facilities, and anyone working with valuable electronic equipment protection from
power surges that can damage or destroy music equipment instantaneously.
Unlike competitive products that utilize low quality MOV’s (Metal Oxide Varistors) for surge protection, Radial’s
Power-1 is built using a USA made MOV. This critical component has been proven to offer superior thermal
protection and have a much longer lifespan than the alternatives. An LED indicator on the front panel illuminates
when the MOV is active, giving you visual confirmation that your gear is protected from voltage spikes.
Created with audio professionals in mind, the Power-1 employs shunt mode technology and avoids passing
contaminated signals to the ground for lower system noise. Additionally, a high-rejection RF interference filter
is used to keep high frequencies and AM radio signals out of the power line, preventing contamination of audio
signals.
Eight rear panel outlets are provided (four with wall-wart spacing to accommodate any PSU size), along with
three front panel outlets and a USB charging port to easily power personal devices. A heavy-duty power on/off
toggle switch, rugged outlet connectors, and steel construction ensure that the Power-1 performs night after night
without fail.

BEFORE YOU GET STARTED
Thank you for purchasing the Radial Power-1 rackmount power supply unit. Before using the Power-1, please
read this short manual and heed all warnings and safety precautions listed. Your safety is our top priority! Should
you have any questions, please review the FAQ page for this product at www.radialeng.com, or contact us directly
Note
: The Power-1 is a surge suppressor, meaning it blocks high voltage spikes that can damage connected
equipment. It does not, however, regulate or stabilize the incoming voltage; this is a task that requires a product
called an AC voltage regulator, and may be beneficial for applications where unreliable or unsteady power
sources are employed.
