Application Notes 55 16. A PPLICATION N OTES 16.1. Dynamic EQ Over the years a number of professional audio products have provided dynamic equalisation functions of various types. What all these systems have in common is that the frequency response of the device varies depending on the si gnal level. Many units are based on compressor/expande r tec[...]

Application Notes 56 If we now replace the parametric with a Helix equaliser and selec t the dynamic EQ, we have some additional controls. Frequency and Q controls are as before, but now we have two pairs of controls replac ing the s ingle cut a nd bo ost con trol; thes e are [ low thres hold] / [low le vel], and [ high threshold] / [high level]. I[...]

Application Notes 57 Without changing modes or making any other sele ctions, we can make the unit operate ‘the other way up’ just by sele cting su itable va lues for th e two thre sholds and levels se e Figure 3 . In this ca se, [low th reshol d] is -20 dBu, [low le vel] is 0dB, [hig h thres hold] is - 5dBu, and [high le vel] is +12dB, so that [...]

Application Notes 58 16.2. What do we mean by all these Q types? The “Q” of an audio equaliser describes the steepnes s of the filter - the degree to which it will affect signals either side of its nominal or “centre” frequenc y. In general, the Q of a peaking filter is defined mathematically: as, where the bandwidth (in Hz) is the range of[...]

Application Notes 59 Proportional Q Proportional Q is the mode of operation familiar to users of the Klark Teknik analogue graphic equalisers, such as the DN360. As the amount of cut or boost is increased, the Q al so increases. This has the effect of making the equaliser “focus” more tightly as the amount of EQ is increased. This allo ws a fai[...]

Application Notes 60 Symmetrical Q This class of equaliser has the same curves in boost as the constant-Q type, but then has cut responses that are symmetrical with the boost ones. In other words, the bandwidth i n cut is defined not according to our usual definition of Q (see constant-Q above) but as “the point were the si gnal is cut by 3dB les[...]

Application Notes 61 16.3. What is AES/EBU? AES/EBU refers to the professional digital audio transmission system, jointly specifi ed by the Audio Engineering Society (AES) and the European Broad cas t Union (E BU), which al lows the tra nsmission of two chann els down a shield ed twiste d pair cab le using time divis ion multip lexing (TDM) with on[...]
