HOC2 STEREO MASTERING JFET OPTO COMPRESSOR

The HOC2 is a stereo version of the HOC1 specifically tailored for mix buss. The direct and compressed parallel paths are step attenuators for precise gain matching, while the linearity of the opto cell dB/V circuit was improved over a 10dB range (HOC1 has 20dB range). Designed custom for Seth Bove.

HEQ2-2 TELEGRAPH2

HEQ2 STEREO MASTERING EQ

The HEQ2 is a stereo 2 band (hi/lo) inductor capacitor EQ designed around customer specs for mastering. The gain range is limited to +-3dB with 0.25dB (+- 0.02dB) steps. Each band (hi/lo) has 12 filters, each with 3 Q values. For the low bands, custom multi-tap inductors were designed with an individual inductance value of 18H (NOT milliHenries!), there are 2 per low band for a total of 36H. Designed for Adam Gonsalves at Telegraph Mastering.
