The 4.24G is a four-channel graphic EQ with an intuitive and straight-forward front panel layout and housed in an all-steel, two space rack-mount chassis. Each channel has 28 bands of 1/3-octave EQ and all the additional audio processing tools needed for flawless equalization and sound control.
Included in the unit is a programmable compressor/limiter for speaker protection and a 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 for fine tuning the audio spectrum.
A large fluorescent backlit display keeps the operator constantly informed of every parameter, function and utility, including metering and user preferences. The 4.24G may be controlled from a remote location using the optional Protea 4.24RD remote control.
