| The Ashly Audio 4.24PS allows for the installation of multiple channel
parametric equalizers where tamperproof, precise audio equalization is
required. Control and programming of either product is easily achieved
through the use of Ashly's exclusive Protea System Software running on
a PC, or by a MIDI controller. The Protea 4.24PS is housed in an all-steel,
2RU chassis, and has four independent channels of fully programmable 12
band parametric EQ with with limiter, high- and low-pass filter, and time
delay functions.
Each parametric band allows for 1/25th to 3.3 octave Q, a twenty-four
step/octave frequency adjustment from 20Hz to 20KHz and level control
of +10/-20dB in 0.5dB increments. High and low shelf filters are adjustable
from 1.6kHz to 20kHz and 20Hz to 240Hz, respectively. High and low pass
filters are 24dB/octave adjustable from 20Hz to 10.6kHz and 33Hz to 20kHz,
respectively. Time delay is adjustable up to 1.364 seconds.
Other features of the Ashly Audio 4.24PS include 24-bit A/D-D/A conversion,
24-bit/100MHz digital processing, RS-232, and MIDI interface, linkable
channels, +6dB/-infinity master gain, and 128 preset locations. Both units
display individual channel numbers using 7-segment displays. Signal present
and signal clip levels are indicated by discrete LEDs.
