The Ashly Audio Protea 3.6SP 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. A backlit 2 x 20 character LCD displays channel and function
settings. Dedicated buttons provide access to all audio functions and
system tools. For even faster set-ups and stronger visualization of Input/Output
routing, EQ, and Filter curves, two USB (one on the front and one on the
rear panel) and RS-232 port is provided for use with Ashly's control software
(Protea Software Suite) and a PC. A six foot USB-A to USB-B cable is provided.
Advantages of using the software include greater preset capacity, and
a very intuitive visual representation of the audio routing and control
The Ashly Audio Protea 3.6SP utilizes state of the art DSP technologies,
beginning with 24 bit, 48kHz delta-sigma A/D converters 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 120MHz 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
Each input allows you to control gain, delay and six filters (each of
them your choice of parametric, low or high shelf). In addition to setting
crossover frequencies, each output may be assigned to any one or a combination
of inputs, allows you to program four parametric, low or high shelf filters,
delay for time delay adjustments, output gain, reverse polarity and a
compressor/limiter for speaker protection. All this in one rack space
with XLR input and output connections.
The Ashly Audio Protea 3.6SP will store up to 30 total presets. A preset
file takes a "snapshot" of all current settings and stores complete
control data for all channels and all audio functions. The Protea 3.6SP
is similar to the older Ashly Protea 3.24CL/CL-d. An existing preset file
from the older *.pcc format can be loaded onto the new 3.6SP unit.
In all, the Ashly Audio Protea 3.6SP is a powerful, easy to use processor
for use in live sound or fixed installation applications combining precise
audio processing and superior sound.
