optional modular expansion cards to provide comprehensive internal DSP processing, AES/EBU input, and networked

digital audio (Cobranet) input.  Please read the entire manual to fully understand the features and capabilities of this

About Ashly

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

designers. 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 thirty 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.

FCC Compliance

This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions:
1. This device may not cause harmful interference
2. This device must accept any interference received, including interference that may cause undesired operation.

2.  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 materials , as they were carefully designed to reduce to 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.

3.  THE  NE MULTICHANNEL  AMP  SERIES
