4. ing small satellite speakers or horns Because horn or small speakers cannot reproduce low frequencies there is the need to filter these low frequencies out of the audio signal This can de done by selecting a low cut freq g e 100HZ with the freq select potentiometer In the output signal High pass the freq below 100HZz will be filtered out the signal is now safe to drive small speakers or horns e GRAPHIC EQUALIZER with more low Freq controls 6K3 10K EXTENDED LOW FREQ CONTROL STANDARD Most of the room acoustic problems are caused by frequencies between 40 and 250 Hz In this region the PXQ2215 has more controls than a standard 15 bands equalizer
