There is no option in the mid or low-mid range at all and also no high pass option. However, the actual curves could have been steeper for todays mixing duties. It offers 7 pre selected frequencies between 3 and 16kHz and only here the bandwidth can be adjusted. Also in the HF department there is just one single peak filter but this time just for boosting. Much more common and usable for todays mixing and mastering duties would be an air band shelving boost option here.
Pultec Eqp 1A Manual Basically StatesIn practise this indeed holds true and we can see the actual bass frequency dip at a much higher frequency within one model compared to another, just as an example.… the more I boost the EQ the more it makes me smile … A reviewers statement misguided by simple loudness increase?Fun fact: Like the original device, all current (hardware) replica models do not have an output gain control. Dial in a boost at 3 and an attenuation at 5, just as an example: Does this already feature a frequency dip? And if so at which frequency exactly? One has no idea and it even gets worse.Due to aged electronics or component variety one has to expect that the actual curve behaviour might differ and also to see each vendors replica implementation to be different from another. In practise, this appears to be rather unpredictable. On top of that, the low frequency behaviour of the boost and cut filters is rather unpredictable if both filters are engaged simultaneously which is exactly the reason why the original manual basically states “Do not attempt to do this!”.Nowadays being refered to as the “Pultec Bass Trick” the idea is that you not only boost in some low end area but also create some sort of frequency dip sligthly above to avoid too much of a boost and muddiness in total.Maybe I’ll take some time for a follow-up article and a closer look into the buffer amplifier design to see if all the hype is justified.![]()
