Tamperproof security.

The Ashly Proteo 4.24GS allows for the installation of multiple channel graphic equalizers where tamperproof, sound shaping equalization is required. Easily control and program the 4.24GS from the 4.24G Main Unit, 4.24RD Remote Control, with a MIDI controller, or with Ashly's exclusive Protea System Software running on a PC. The Protea 4.24GS is housed in an all-steel, 2RU chassis, and has two independent channels of fully programmable 28-band graphic EQ with with limiter, high- and low-pass filter, and time delay functions.

Each channel allows for 28 bands of 1/3-octave, ISO centered, constant Q filters, ranging from 31Hz to 16kHz. 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. The 4.24GS displays individual channel numbers with 7-segment displays. Discrete LEDs indicate signal present and signal clip levels. Rear-panel connections include balanced XLR and 1/4" ins/outs for each channel, RS-232, MIDI In, Out/Thru, and Ashly's exclusive digital remote control protocol via two standard XLR connectors.
