Tamper-proof EQing for installed systems.

The Protea 2.24GS 2-Channel Graphic EQ lets you install multiple channel graphic equalizers where tamperproof, sound shaping equalization is required. Easily control and program the 2.24GS from the 4.24G Main Unit, a 4.24RD Remote Control, a MIDI controller or with Ashly's exclusive Protea System Software on a PC. The Protea 2.24GS is housed in an all-steel, 1RU chassis, and has two independent channels of fully programmable 28-band graphic EQ 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 2.24GS 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.
