Robzebr Posted May 15, 2013 Share Posted May 15, 2013 Gain - Boost or cut in db Q - width of the boost or cut Freq - what frequency to boost or cut Highs ? Lows ? I'm not clear on the function of the Highs and Lows parameters... Can somebody explain how they differ from the Freq parameter? If I want to boost 300 hz and also 1500 hz... can I do that with one instance of the Parametric EQ? or do I need 2.. one for the lows and one for the highs...? Extra Credit: Can somebody explain the Parametric EQ LOW and Parametric EQ HIGH graphs that are in Meambos Guide? Obviously they refer back to the Highs and Lows parameter in the EQ .... How does that differ from Freq? Thanks... Quote Link to comment Share on other sites More sharing options...
pfsmith0 Posted May 15, 2013 Share Posted May 15, 2013 Hi Rob, You will need 2 instances of the parametric EQ to adjust 300 Hz and 1500 Hz. I often use 3-4 instances to EQ my acoustic intruments to keep them from feeding back at various frequencies. The parametric EQ has basically 3 frequency bands; Low, Variable, and High. Low: as you can see from the graphs, it only cuts or boosts frequencies below 200 Hz. The FREQ control has no affect here. Variable: use the FREQ control to set which frequency to center the affect (43 to 4500 Hz). Use GAIN to set the boost/cut at that frequency (-12dB to +12dB). Use Q to set how many frequencies around the center to affect. For feedback control I usually have to set GAIN = min and Q = max (this gives a very deep but narrow cut). High: as you can see from the graphs, this only cuts/boosts frequencies above 2kHz. FREQ has no affect here. There is more discussion at http://line6.com/support/topic/335-frequency-response-graphs-for-hd500-eqs/ Quote Link to comment Share on other sites More sharing options...
Robzebr Posted May 15, 2013 Author Share Posted May 15, 2013 Thank You! Perfect! So just to recap ... If I am boosting 300hz and 1500 hz... (just an example) I need 2 parametric EQs and can do the boosting (or cutting) with the Freq ... and just leave the HIGH and LOW ... alone... That answers my question...

pfsmith0 Posted May 16, 2013 Share Posted May 16, 2013 Yes, that's what I'd do. Quote Link to comment Share on other sites More sharing options...
spaceatl Posted May 16, 2013 Share Posted May 16, 2013 If you are using Q's that are a couple of octaves and looking for a fairly smooth curve it seems like you could use one PE cutting 900 Hz with a slightly wider Q? I tend to prefer using a single cut filter over two boost filters...If you are trying to tune something more notched it might not work, but it sure seems like it might...
