Operating Manual - PROTEA SYSTEM II 3.24CL Crossover / System Processor

1. INTRODUCTION

Thank you for your purchase of this Ashly Protea 3.24CL Digital Crossover/System Processor. The

Protea SYSTEM II 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.

Your new 3.24CL is a three input/six output digital signal processor capable of precise control of a

broad range of audio functions. The front panel interface allows quick access to all control parameters by

offering dedicated function buttons, eliminating the need for hidden sub-menus. The 3.24CL-d is the same

as the 3.24CL in every respect except for the input and output delay structure.

1.1 AUDIO FEATURES

The Protea 3.24CL utilize state of the art DSP technologies, beginning with 24 bit, 48kHz delta-sigma A/D convert-

ers with 128x oversampling. Digital processing includes Gain, Polarity Invert, Parametric EQ, Shelving Filters, Time Delay,

Crossover Functions, Compression, Limiting, and Signal Routing, all taking place in twin high performance DSP proces-

sors. 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

provide access to all audio functions and system tools. The display indicates the current preset number, then subse-

quently 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.

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 for model 3.24CL is on the back panel. The Protea 3.24CL uses a universal input

power supply which will accept any line voltage from 80VAC to 260VAC, 50-60Hz, and is resistant to voltage dips, or

"brown outs". 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 3.24CL. 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.
