About Ashly

Ashly Audio was founded in 1974 by a group of recording engineers, concert sound professionals, and electronics design-

ers. The first products were elaborate custom consoles for friends and associates, but business quickly spread to new clients and 
the business grew. The philosophy we established from the very beginning holds true today: to offer only the highest quality 
audio tools at an affordable cost to the professional user – ensuring reliability and long life. More than 35 years later, Ashly 
remains committed to these principles. 

Ashly’s exclusive Five Year, Worry- Free Warranty remains one of the most liberal policies available on any commercial- 

grade product. The warranty covers every product with the Ashly brand name, and is offered at no extra cost to you, our customer. 

Unpacking

As a part of our system of quality control, every Ashly product is carefully inspected before leaving the factory to ensure 

flawless appearance.  After unpacking, please inspect for any physical damage.  Save the shipping carton and all packing ma-
terials, as they were carefully designed to reduce to a minimum the possibility of transportation damage should the unit again 
require packing and shipping.  In the event that damage has occurred, immediately notify your dealer so that a written claim 
to cover the damages can be initiated.

The right to any claim against a public carrier can be forfeited if the carrier is not notified promptly and if the shipping carton 

and packing materials are not available for inspection by the carrier. Save all packing materials until the claim has been settled.
