With wide bandwidth and headroom it is natural, musical and detailed, letting engineers and musicians consistently record vibrant tracks. Equally at home amplifying a vintage condenser microphone or a plugged-in acoustic guitar, it serves as an invisible link between the microphone or instrument and the recording device. A dead-quiet universal switching power supply accepts 100 to 240 V AC, and every preamp function, including 48V and HPF, has its own indicator LED.\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;\"\u003eGain with the output trim\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;\"\u003e10‑75 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;\"\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; -130 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;\"\u003eMic input response, -3 dB\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;\"\u003e4.5 Hz - 390 kHz\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;\"\u003eMaximum output level\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+25 dBu\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\n\u003cstrong\u003eFast, musical transimpedance architecture\u003c\/strong\u003e; fully balanced, transformerless XLR mic input\u003c\/li\u003e\n\u003cli style=\"margin:0 0 6px;\"\u003e\n\u003cstrong\u003eRibbon mic mode\u003c\/strong\u003e: relay bypass of the input capacitors, 20 kΩ input impedance and 48V lockout\u003c\/li\u003e\n\u003cli style=\"margin:0 0 6px;\"\u003e\n\u003cstrong\u003eHi-Z instrument DI\u003c\/strong\u003e on the front panel: 1 MΩ unbalanced, 2 MΩ balanced\u003c\/li\u003e\n\u003cli style=\"margin:0 0 6px;\"\u003e\n\u003cstrong\u003e12-position gold contact rotary gain switch\u003c\/strong\u003e and 0.5 % precision metal film resistors\u003c\/li\u003e\n\u003cli style=\"margin:0 0 6px;\"\u003e\n\u003cstrong\u003e+10 dB output trim\u003c\/strong\u003e for fine level and level riding\u003c\/li\u003e\n\u003cli style=\"margin:0 0 6px;\"\u003e75 Hz, 12 dB\/octave high-pass filter, optimised for minimum phase shift\u003c\/li\u003e\n\u003cli style=\"margin:0 0 6px;\"\u003eThree outputs at once: XLR balanced, TRS balanced and TS unbalanced\u003c\/li\u003e\n\u003cli style=\"margin:0 0 6px;\"\u003eTwo-colour peak LED; LED indicators for 48V, ribbon mode and HPF\u003c\/li\u003e\n\u003cli style=\"margin:0 0 6px;\"\u003eSealed gold contact relays; no electrolytic capacitors in the signal path\u003c\/li\u003e\n\u003cli style=\"margin:0 0 6px;\"\u003eBuilt-in universal AC power supply; half-width 1U aluminium chassis; made in the USA\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;\"\u003eRibbon mic mode, built in\u003c\/h3\u003e\n\u003cp style=\"margin:0 0 12px;\"\u003ePushing the ribbon switch locks out 48V phantom power to protect delicate ribbon elements, raises the mic input impedance from 8.1 kΩ to 20 kΩ and bypasses the DC blocking input capacitors with sealed gold contact relays.
