Operating Manual - PROTEA™ 4.8SP and 3.6SP System Processors
1. INTRODUCTION
Thank you for your purchase of this Ashly Protea 4.8SP or 3.6SP 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 4.8SP has four inputs and eight outputs, while the 3.6SP 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 4.8SP and 3.6SP 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.
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.
2. UNPACKING
As a part of our system of quality control, every Ashly product is carefully inspected before leaving the factory to
ensure awless 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 notied 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 4.8SP and 3.6SP 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 qualied service technician for fuse replacement, replacing only with the same
type and rating fuse.

4. FRONT PANEL CONTROL FEATURES
4.1 Function Keys and Data Wheel
To the right of the LCD display
are two unlabeled function keys and a
rotary data wheel. All audio and system
parameters are edited using these three
controls. Each of the two lines of text
on the LCD display correspond to a
dedicated function key, so that various
tasks on both lines may be selected using
their respective keys. The selected task is
highlighted by a ashing underscore beneath the word or number, and the parameter is then adjusted up or down with the data
wheel. The Esc key will exit any activity and return to the top level showing the preset number and name.
4.2 Presets
The 4.8SP and 3.6SP are organized into 30 programmable presets, each completely dening the conguration of all
inputs and outputs along with their respective audio components. There are ten repeating preset congurations pre-loaded into
the unit which are simply starting points for common applications, and all can be modied, renamed, and saved to suit the end
user. Please Note: In addition to the 30 preset numbers, a constantly refreshed Working Preset is used to take a "snapshot" of
all current settings should the unit be turned off before changes can be saved.
When the unit is rst powered up, the last working preset is loaded, displaying the number and name last used before
the unit was turned off. Any modications made to that preset before saving it will remain in the working preset until either the
modied preset is saved, or a fresh preset is recalled. When modications to an existing preset are made without saving, the
display adds the text (modied) after the preset number.
4.3 Input Select
There are four XLR audio inputs on the
4.8SP (three on the 3.6SP), and each input is processed independently and may be routed to one or
several outputs. Select an input to edit its Gain, EQ,
and Delay settings, or to mute it. Signal routing
occurs in the output section.
4.4 Output Select
There are eight outputs on the
4.8SP (six on the 3.6SP), and each output
can obtain its source from any input or
combination of inputs. Select an output
channel to edit its Source, Gain, Polarity, EQ, Delay, Crossover, or Limiter
functions.
4.5 LED Indicators
Each input and output has a ve segment LED array for audio level display, ranging from -20 through clipping. The
-20 LED is two-color, also serving as the Mute indicator by turning red. The meter scale is factory set so that 0 on the meter is
0dBu (0.775Vrms), however it can be easily changed to VU scale (0 = +4dBu, or 1.228Vrms) within the Util menu.
