The 3-band EQ is built around a single-stage parallel tuning architecture that minimises circuitry and delivers natural tonal shaping from 20 Hz to 20 kHz, and the compressor is based on an optical attenuator for gentle limiting to fairly heavy compression while remaining neutral and transparent.\u003c\/p\u003e\n\u003ctable style=\"border-collapse:collapse;margin:6px 0 18px;width:100%;max-width:100%;table-layout:fixed;\"\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:12px 8px;text-align:left;border:1px solid #DDE2E8;vertical-align:top;word-break:normal;overflow-wrap:break-word;width:55%;color:#5a6170;font-size:13px;text-transform:uppercase;letter-spacing:.05em;\"\u003eMic preamp gain, 5 dB steps\u003c\/td\u003e\n\u003ctd style=\"padding:12px 8px;text-align:left;border:1px solid #DDE2E8;vertical-align:top;word-break:normal;overflow-wrap:break-word;font-weight:bold;color:#006d77;font-size:17px;\"\u003e10‑65 dB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:12px 8px;text-align:left;border:1px solid #DDE2E8;vertical-align:top;word-break:normal;overflow-wrap:break-word;width:55%;color:#5a6170;font-size:13px;text-transform:uppercase;letter-spacing:.05em;\"\u003eNoise referred to input, 50 Ω\u003c\/td\u003e\n\u003ctd style=\"padding:12px 8px;text-align:left;border:1px solid #DDE2E8;vertical-align:top;word-break:normal;overflow-wrap:break-word;font-weight:bold;color:#006d77;font-size:17px;\"\u003e\u0026lt;
