ristics can be altered from G ENTLE to S TEEP , (also see point 9: B OOST /C UT ,
page 16).
IIm mp po orrtta an ntt:: If you switch on the N OTCH mode, the bandwidth control Q
must be set at 0.6 (extreme right), so as to ensure a 1:1 level ratio with the
original signal.
Narrower notches can be obtained if the Q control is turned to the
extreme left. However, then the output level is also reduced by around
20dB.
Figure 4 shows the curves for the N OTCH with G ENTLE and S TEEP characte-
ristics at Q0.6, along with the same curves at Q3.6.
