An efficient switching power supply keeps the unit cool under continuous use, and the optional ISA ADN8 card adds eight Dante, ADAT and AES3 outputs at up to 24-bit\/192 kHz and 122 dB of dynamic range.\u003c\/p\u003e\n\n\u003ch3\u003eEight input jacks, all permanently connected\u003c\/h3\u003e\n\u003cp\u003eDedicated mic and line connectors on every channel remove the need to swap a single combo jack between sources — a microphone, a line feed from a console, and an instrument can all stay wired in, with input selection just a front-panel button press. That makes ISA 828 MkII a fixture in the rack rather than a device to unplug and replug for every session, which matters especially for mobile rigs and studios with rotating clients.\u003c\/p\u003e\n\n\u003ch3\u003e80 dB of gain and switchable impedance for any microphone\u003c\/h3\u003e\n\u003cp\u003eFour input impedance settings — from 600 Ohms through the original ISA 110 value (1.4 kOhms), 2.4 kOhms, up to 6.8 kOhms — let you tailor tonal character to a specific microphone instead of settling for one compromise setting across every source. Stepped gain up to 60 dB plus a continuously variable +20 dB trim give 80 dB of headroom on the mic input and 30 dB on line, and a switchable insert on every channel lets you patch in a compressor or EQ ahead of conversion — including when the unit runs digitally with the ADN8 card, where the analogue outputs double as insert sends.\u003c\/p\u003e\n\n\u003ch3\u003eKEY FEATURES\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e8 preamps with a Lundahl LL1538 transformer on every input\u003c\/li\u003e\n\u003cli\u003eDedicated mic and line connectors on every channel, DI on channels 1-4\u003c\/li\u003e\n\u003cli\u003e4 input impedance settings, including the classic ISA 110 value\u003c\/li\u003e\n\u003cli\u003eGain up to 60 dB in 10 dB steps plus a continuously variable +20 dB trim (up to 80 dB on mic)\u003c\/li\u003e\n\u003cli\u003eHigh-pass filter, 75 Hz, 18 dB\/octave\u003c\/li\u003e\n\u003cli\u003e6-segment LED metering per channel, calibratable\u003c\/li\u003e\n\u003cli\u003eSwitchable rear-panel insert on every channel\u003c\/li\u003e\n\u003cli\u003eAnalogue output via 8x DB25\u003c\/li\u003e\n\u003cli\u003eSwitching power supply — quiet, cool continuous operation\u003c\/li\u003e\n\u003cli\u003eOptional ISA ADN8 card: Dante, ADAT, AES3 up to 24-bit\/192 kHz\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTECHNICAL SPECIFICATIONS\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eChannels: 8 independent microphone preamps\u003c\/li\u003e\n\u003cli\u003eInputs: 8x XLR (mic), 8x TRS (line), 4x TS (instrument, channels 1-4)\u003c\/li\u003e\n\u003cli\u003eMic gain: up to 60 dB in 10 dB steps + 0-20 dB trim\u003c\/li\u003e\n\u003cli\u003eInstrument gain: 10-40 dB (channels 1-4)\u003c\/li\u003e\n\u003cli\u003eInput impedance (mic): 600 Ohms \/ 1.4 kOhms (ISA 110) \/ 2.4 kOhms \/ 6.8 kOhms\u003c\/li\u003e\n\u003cli\u003eHPF: 75 Hz, 18 dB\/octave\u003c\/li\u003e\n\u003cli\u003eFrequency response: 10 Hz-122 kHz\u003c\/li\u003e\n\u003cli\u003eAnalogue outputs: 8x via DB25 connector\u003c\/li\u003e\n\u003cli\u003eOptional A-D conversion: 24-bit\/192 kHz, 122 dB dynamic range (ADN8 card)\u003c\/li\u003e\n\u003cli\u003eDimensions: 3.5 x 19 x 12.8 in (2U)\u003c\/li\u003e\n\u003cli\u003eWarranty: 3 years\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"FOCUSRITE","offers":[{"title":"Default Title","offer_id":54246842564945,"sku":"47996","price":3417.01,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/8741\/0769\/files\/FocusriteISA828mkII1.jpg?v=1783947276","url":"https:\/\/wrdtunes.com\/fr\/products\/focusrite-isa-828-mkii","provider":"Wired Tunes","version":"1.0","type":"link"}
