Pultec EQM-1S Mastering Equalizer

Since rereleasing the EQP-1A & EQP-1S, customers have asked when Pultec planned to do mastering versions of these iconic 3U products. In October 2018 (AES NYC) Pultec announced the EQM-1A, the mastering version of the EQP-1A. They are now excited to announce Pultec EQM-1S, the mastering version ofthe ever-popular EQP-1S EQ, with a couple of extra tweaks. Complete with full-range progressive-taper Elma Switch stepped controls as in the EQM-1A3, EQM-1S3 & EQM-1A mastering EQs, the BOOST/ATTEN controls provide 0.5dB steps for the initial ~50% of rotation and then increase step size as rotation is increased from 50% - 100%. This provides fine control (subtle boost/cut) for mastering/mix-bus applications, while still delivering the full range (16-20 dB) of BOOST/ATTEN for more aggressive tracking/mixing applications. In addition to adding mastering controls, Pultec have replaced the 6k peak boost center frequency with the 16k center, which is so popular on the 1A/1A3 models. So whether your track/mix needs the magical 16k air band or the full 5k/10k shelf boost, you have the option in a single equalizer.
