Pultec EQM-1S Tube Mastering Equalizer
Description
The Pultec EQM-1S mastering eq is a modern recreation of the rare EQP-1S with added stepped controls for mastering applications and different frequency points and curves.
The Pultec EQM-1S has been meticulously reproduced from the original EQP-1S3 by Dr Steve Jackson, using only original-spec components to deliver the same stunning sound of the original vintage units. Adapted for mastering applications the EQM-1S uses Progressive-taper Elma switch controls with a 0.5dB of boost and cut for precise settings and easy recall. As a result, the gain has been reduced to 10dB boost/cut instead of the original values.
Pultec's unique design uses two bands with separate boost and cut controls that can be combined to create a resonant shelf curve. These curves are key to the Pultec sound by boosting a band without unwanted frequency build-up, offering a tight and musical sound. For mastering applications, these curves allow to add weight and foundations without boxiness and add presence or air without harshness. The EQM-1S also offers the choice between peak and shelf modes which delivers different sonic characteristics, as well as boasting different frequency points compared to the EQP-1A:
Low Shelf Boost/Cut: 30kcs 40kcs, 70kcs and 100kcs
High Bell Boost:1kcs, 2kcs, 3kcs, 4kcs, 5kcs, 6kcs, 8kcs, 10kcs, 12kcs
High Shelf Boost: 5kcs, 10kcs
High Shelf Cut: 5kc, 10kc, 20kc
Furthermore, their passive designs ensure that no distortion is generated by the curves. This design is compensated by a tube driven push-pull amplification placed after the equalisation stage, compensating for the loss of volume.
