8. that has a varying interpretation depending on the type of filter applied As a whole if you increase its value for the 6 central channels its effect is comparable to the Q factor of certain parametric filters However given the fact that we provide different types of filter shapes from the dropdown menus the R value is relative to the shape of the chosen filter and therefore it also involves the bandwidth assigned to that DUY Deep Analog EQ User s Manual Page 12 specific band Our advice is to visualize the result in the graph at the lovver part of the user interface to see the final curve applied to your sound Warning You should be aware that R values close to 1 00 will behave as resonant filters This could imply your hearing outstanding tones at the selected frequencies when you insert your signal through the filter Generally for values above 0 95 filters may become unstable delivering very high gains independent from the G Gain control For this reason you will see a red circle surrounding your frequency dot on the graph to alert you about this circumstance At the same time if you hover the mouse over the dot a Peak Warning message will appear and a sign will appear next to the value on the knob 6 3 3 Frequency Fc This is the value of the characteristic frequency of your filter Its meaning is different in high pass low pass high shelf low shelf or band pass filters see their descriptions but in
9. As a matter of fact their design didn t please its own creators in search of a linear response However the sonic response of these valves was more than impressive because they excited odd harmonics which created a very pleasant to the ears variation of the original sound 5 Dual Valve The original intention of its classic design was to obtain a very important signal gain but its double configuration and the inexact pairing of both units made them very difficult to calibrate Additionally feedback loops caused them electronic harm However in our carefully matched model of the original analog device we will never burn the component and at the same time we will obtain a somewhat uncontrolled level of distortion This can make the resulting distortion slightly more organic in relation to the plain input signal Of course by using the Depth control you can adjust the amount of this effect you would like to include in your sound 6 FET Field Effect Transistors are not perceived as perfect amplification devices by engineers However we have studied that a properly polarized FET can deliver a certain amount of magic to the sound You have to try it to understand the special colour obtained which is complex to describe in words in this manual A certain mild harshness combined with a smoothed non linearity would probably be the best description If you choose this option you should know that the device we have modelled corresponds
