It delivers ultra-clean SSL SuperAnalogue grade recordings and also features a switchable VHD mode. SSL's patented Variable Harmonic Drive uses a 100 % analogue signal path to generate rich harmonic distortion: as VHD input gain rises, it introduces 2nd or 3rd harmonic distortion, or a blend of the two. At lower gain it adds gentle valve-style warmth or a touch of transistor edge; at high gain it delivers fierce, trashy transistor-style grunge.\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;\"\u003eMaximum preamp gain\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+75 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;\"\u003eHarmonic blend with VHD\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;\"\u003e2nd \/ 3rd\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;\"\u003e18 dB\/octave high‑pass filter\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;\"\u003e15‑500 Hz\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;\"\u003eHi‑Z instrument input\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;\"\u003e1 MΩ\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\n\u003ch3 style=\"font-size:17px;font-weight:700;color:#0D1B3E;text-transform:uppercase;letter-spacing:.06em;margin:30px 0 12px;padding:0 0 7px;border-bottom:2px solid #006D77;\"\u003eKey features\u003c\/h3\u003e\n\u003cul style=\"margin:0 0 14px;padding-left:20px;\"\u003e\n\u003cli style=\"margin:0 0 6px;\"\u003e\u003cstrong\u003eSSL SuperAnalogue grade preamp\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli style=\"margin:0 0 6px;\"\u003e\n\u003cstrong\u003e2nd order harmonics\u003c\/strong\u003e: valve warmth to extreme distortion\u003c\/li\u003e\n\u003cli style=\"margin:0 0 6px;\"\u003e\n\u003cstrong\u003e3rd order harmonics\u003c\/strong\u003e: transistor edge to totally trashed\u003c\/li\u003e\n\u003cli style=\"margin:0 0 6px;\"\u003eAbsolute control with the 2nd \/ 3rd order harmonic blend (DRIVE)\u003c\/li\u003e\n\u003cli style=\"margin:0 0 6px;\"\u003eVariable Harmonic Drive (VHD) in \/ out switch\u003c\/li\u003e\n\u003cli style=\"margin:0 0 6px;\"\u003eSwitchable variable high-pass filter, 15-500 Hz, 18 dB\/octave\u003c\/li\u003e\n\u003cli style=\"margin:0 0 6px;\"\u003e+48 V phantom power, 20 dB PAD, Hi-Z and polarity switches\u003c\/li\u003e\n\u003cli style=\"margin:0 0 6px;\"\u003eFront TRS line \/ DI input and tri-colour signal LED\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3 style=\"font-size:17px;font-weight:700;color:#0D1B3E;text-transform:uppercase;letter-spacing:.06em;margin:30px 0 12px;padding:0 0 7px;border-bottom:2px solid #006D77;\"\u003eUltra-clean to heavy distortion\u003c\/h3\u003e\n\u003cp style=\"margin:0 0 12px;\"\u003eWith VHD off the preamp is designed for a transparent sound, great for acoustic guitars, vocals and strings.
