Ashly 2.24PS

The 2.24PS 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 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 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 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.
