EQM-1S is the mastering version of the 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 the 6k peak boost centre frequency has been replaced with a 16k centre, 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. 30, 40, 70, 100 CPS (Hz) shelf boost, 0 - 13.5 dB (FRPT* stepped control, 0.5 dB steps 0-5 dB) 30, 40, 70, 100 CPS shelf attenuate, 0 - 17.5 dB (FRPT* stepped control, 0.5 dB steps 0-5 dB) 1, 2, 3, 4, 5, 8, 10, 12, 16 KCS (kHz) peak boost, 0 - 18 dB (FRPT* stepped control, 0.5 dB steps 0-5 dB) 5, 10 KCS (kHz) shelf boost, 0 - 14.5 dB (FRPT* stepped control, 0.5 dB steps 0-5 dB) 5, 10, 20 KCS shelf attenuate, 0 - 16 dB (FRPT* stepped control, 0.5 dB steps 0-5 dB) Input Impedance: ~600 Ohms Output Impedance: ~50 Ohms Noise: 92 dB below +10 dBm Distortion: ≤ 0.15% at +10 dBm into 600 Ohms Amplifier: Flat, 20 CPS to 20 KCS, +/- 0.5 dB Tubes: 1 ea 12AU7, 12AX7, 6X4 * FRPT = full-range, progressive-taper - Step size increases when control is rotated beyond 50% rotation.
