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.
1 .1 AUDIO FEATURES
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.
1 .2 USER INTERFACE
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.
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 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.
3 . AC POWER REQUIREMENTS
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.
