Now we get a combination of boosts, cuts and a low cut filter placed at 200Hz, if possible. Some EQs had no HPF and some had a fixed setting but on any of the ones with variable low cut I began by flattening out the faders, noting the dB level at 200Hz and then increasing the frequency of low cut until 200Hz showed a reduction of -3dB. Fader settings for this test were 400Hz -3dB, 500 -6, 630 -6, 800 -3, 1.25k +3, 1.6k +6, 2k +6 and 2.5kHz +3dB. In the photo you can see the ART HQ-31 set for the wavy test; its High Pass filter knob is shown in the inset.
Note that some EQs have no variable high-pass filter. Others have a fixed HPF that can be switched in and out. The TDM has one that is set via internal jumpers.
