Operating Manual - PROTEA™ DSP480 and DSP360 System Processors

1 . INTRODUCTION

Thank you for your purchase of this Ashly Protea DSP480 or DSP360 Digital Crossover/System

Processor. The Protea series builds on the tradition of quality and value which has earned Ashly its place

as a market leader in crossovers, equalization, and signal processing.

The DSP480 has four inputs and eight outputs, while the DSP360 has three inputs and six outputs.

The front panel interface allows quick access to all control parameters by offering dedicated function

buttons, eliminating the need for hidden sub-menus. For even faster set-ups and stronger visualization of

Input/Output routing, EQ, and Filter curves, a USB port is provided for use with Windows™ Protea NE

Software. Full control by third party controllers is also available via RS-232.

The Protea DSP480 and DSP360 utilize state of the art DSP technologies, beginning with 24 bit, 48kHz delta-sigma A/D

converters with 128x oversampling. Digital processing includes Gain, Parametric EQ, Shelving Filters, Time Delay, Crossover

Functions, Compression, Limiting, and Matrix Routing, all taking place in twin 120MHz Motorola DSP56362 high performance

DSP processors. D/A conversion uses 24 bit delta-sigma converters with 128x oversampling. All inputs and outputs are precision

balanced and RF protected using XLR connectors.

Front Panel Interface: A backlit 2 x 20 character LCD displays channel and function settings. Dedicated buttons pro-

vide access to all audio functions and system tools. The display indicates the current preset number, then subsequently shows

the selected input or output and its active control parameters. Five segment LED arrays on each input and output provide audio

level information and mute status.

Computer Interface with Protea Software: The computer interface uses Ashly Protea software for Windows, which

allows complete PC control of the unit through a USB jack. Protea software can be downloaded at no cost from the Ashly web

site. Advantages of using the software include greater preset capacity, and a very intuitive visual representation of the audio

routing and control process.

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 minimize 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.

Note: The AC power switch is on the back panel . The Protea DSP480 and DSP360 use a universal input power sup-

ply which will accept any line voltage in the range of 100VAC to 240VAC, 50-60Hz. A standard IEC-320 grounded AC inlet is

provided on the rear panel to accept the detachable power cord. Never remove the AC earth ground connection to the unit .

In the event of fuse failure, refer the product to a qualified service technician for fuse replacement, replacing only with the same

type and rating fuse.
