1 . INTRODUCTION

Thank you for your purchase of this Swamp 4-8SP Digital Crossover/System Pro-

cessor. The 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 4-8SP has four inputs and eight 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 Swamp 4-8SP 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

provide 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.

Protea NE Software: The computer interface uses Ashly PROTEA NE SOFTWARE for Windows, which

allows complete PC control of the unit through a USB jack. Protea NE software is supplied with each unit, or 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 Swamp 4-8SP use a universal input power supply 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.
