Unlike the ISA One, ISA Two has no slot for a digital card — the output is analogue only, meant to feed an external A-D converter, interface or console.\u003c\/p\u003e\n\n\u003ch3\u003eMatching input impedance to any microphone, vintage included\u003c\/h3\u003e\n\u003cp\u003eFour selectable input impedance values, including the original ISA 110 setting, let you tailor tonal character to a specific microphone rather than settling for one compromise setting — a lower impedance gives a more transparent, modern result, while a higher one restores the warmth typical of vintage tube or ribbon mics from the 60s and 70s. The setting is remembered after power-down, so a configuration dialled in for a particular mic doesn't get lost between sessions.\u003c\/p\u003e\n\n\u003ch3\u003e80 dB of gain headroom and an insert without leaving the analogue path\u003c\/h3\u003e\n\u003cp\u003eStepped gain from 0 to 60 dB in 10 dB increments, plus a continuously variable trim up to +20 dB, gives up to 80 dB of gain in total — enough headroom for quiet acoustic sources without pushing the noise floor higher than needed. A balanced insert on each channel, switched in from the front panel, lets you patch in an outboard EQ or compressor directly within the preamp's signal path, and 8-segment LED metering with a rear-panel calibration control keeps the signal aligned with whatever converter or DAW is on the receiving end.\u003c\/p\u003e\n\n\u003ch3\u003eKEY FEATURES\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e2 independent microphone preamps with Lundahl LL1538 transformer\u003c\/li\u003e\n\u003cli\u003e4 switchable input impedances, remembered after power-down\u003c\/li\u003e\n\u003cli\u003eMic gain 0-60 dB in 10 dB steps plus up to +20 dB trim (up to 80 dB total)\u003c\/li\u003e\n\u003cli\u003eRear-panel line input and front-panel DI\u003c\/li\u003e\n\u003cli\u003eVariable high-pass filter, 16-420 Hz\u003c\/li\u003e\n\u003cli\u003ePolarity inversion on each channel\u003c\/li\u003e\n\u003cli\u003eBalanced send\/return insert, switched in from the front panel\u003c\/li\u003e\n\u003cli\u003e8-segment LED metering with calibrated reference level\u003c\/li\u003e\n\u003cli\u003eAnalogue output only — no digital card slot\u003c\/li\u003e\n\u003cli\u003eRugged, all-metal enclosure\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTECHNICAL SPECIFICATIONS\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eChannels: 2 independent microphone preamps\u003c\/li\u003e\n\u003cli\u003eMic gain: 0-60 dB in 10 dB steps plus 0-20 dB trim\u003c\/li\u003e\n\u003cli\u003eEIN: -127 dBu at 60 dB gain (150 Ohm source, 22 Hz-22 kHz filter)\u003c\/li\u003e\n\u003cli\u003eLine gain: -20 to +10 dB in 10 dB steps plus trim\u003c\/li\u003e\n\u003cli\u003eInstrument gain: 10-40 dB, continuously variable\u003c\/li\u003e\n\u003cli\u003eInput impedance: 4 switchable values, including original ISA 110 setting\u003c\/li\u003e\n\u003cli\u003eHPF: 16-420 Hz, variable\u003c\/li\u003e\n\u003cli\u003eTHD+N (line): 0.0001% at 0 dBu\u003c\/li\u003e\n\u003cli\u003eInsert: balanced send\/return on TRS jack per channel\u003c\/li\u003e\n\u003cli\u003eMetering: 8-segment LED, calibrated reference level\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"FOCUSRITE","offers":[{"title":"Default Title","offer_id":54246844039505,"sku":"1048","price":841.87,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/8741\/0769\/files\/FocusriteISATwo1.jpg?v=1783947231","url":"https:\/\/wrdtunes.com\/fr-fr\/products\/focusrite-isa-two","provider":"Wired Tunes","version":"1.0","type":"link"}
