Pultec EQM-1S Tube Mastering Equalizer

Since rereleasing the EQP-1A & EQP-1S, customers have asked when we planned to do mastering versions of these iconic 3U products. We are excited to introduce you to the mastering version of our ever-popular EQP-1S EQ, with a couple of extra tweaks.

Complete with full-range progressive-taper Elma Switch stepped controls as in our 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, we’ve 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.
