2 channels of fully programmable parametric EQ.
The Protea 2.24PS 2-Channel Parametric EQ allows for the installation of multiple channel parametric
equalizers where tamperproof, precise audio equalization is required. Ashly's exclusive Protea System Software running on
a PC or a MIDI controller can easily control and program the processor. The Protea 2.24PS is housed in an all-steel, 1RU chassis,
and has two 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 24-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 from20Hz to 10.6kHz and 33Hz
to 20kHz, respectively. Time delay is adjustable up to 1.364 seconds.
Other features 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.
