Ashly Audio Protea 4.24G 4-Channel Graphic EQ System Processor

As simple as your old-style graphic but more powerful.

Full control of the Protea 4.24G 4-Channel Graphic EQ System Processor is accomplished from the front panel in an intuitive and straight-forward layout. It's like using your old analog equalizer, only with extra features and benefits to simplify your audio chain requirements. Housed in an all-steel 2RU package, the 4.24G has all the audio processing tools needed for flawless equalization and sound control. In addition to 28 bands of 1/3-octave EQ are a programmable compressor/limiter for speaker protection and programmable delay of up to 1.364 seconds for time delay applications required by speaker arrays and clusters or monitor speakers. Individual, programmable 24dB/octave high- and low-pass filters allow you to zero in and fine tune the audio spectrum you need to work in. A large 240 x 64 fluorescent backlit display keeps you constantly informed of every parameter, function and utility, including metering and user preferences. The 4.24G may be controlled from a Remo te location using the Protea 4.24RD.
