Each mic pre has variable input impedance, to provide a range of subtly different sonic options when using microphones, including an 'ISA 110' setting, which replicates the impedance of the original Focusrite mic pre.\u003cbr\u003e\u003cbr\u003eUp to 60dB of gain is available, with a further +20dB of continuously variable trim, providing a huge 80dB gain range. The high-pass filter with fixed 75Hz frequency and 18dB\/octave roll-off. ISA 828 MkII features high-pass filters, calibratable per-channel, six-segment LED meters, and switchable rear-panel insert points, which allow the use of inline processors such as compressors or EQs.\u003cbr\u003e\u003cbr\u003eDedicated connectors for mic and line-level inputs allow all sources to be connected simultaneously, making ISA 828 MkII perfect for permanent installation in a rack. New to the ISA 828 MkII is an updated power supply that allows for more efficient power consumption, a reduction in heat generation, and extremely reliable operation. The optional ISA ADN8 analogue-to-digital expansion card provides eight Dante, ADAT and AES3 outputs at rates of up to 24-bit\/192kHz.\u003c\/p\u003e\n\n\u003chr noshade\u003e\n\n\u003cp style=\"text-align: left;\"\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cul\u003e\n\n\u003cli\u003eOptional A-D card with up to 192kHz, 24-bit sampling offers high-quality, precision digital audio conversion to Dante, ADAT and AES3\u003c\/li\u003e\n\n\u003cli\u003eClassic ISA mic preamp design featuring Lundahl LL1538 input transformer\u003c\/li\u003e\n\n\u003cli\u003eSwitching power supply design allows for efficient and cool operation\u003c\/li\u003e\n\n\u003cli\u003eFront-panel instrument inputs to first four channels\u003c\/li\u003e\n\n\u003cli\u003eLine inputs with dedicated input connectors and front-panel switch\u003c\/li\u003e\n\n\u003cli\u003eSwitchable input impedance including classic ISA 110 setting\u003c\/li\u003e\n\n\u003cli\u003eHigh-pass filters\u003c\/li\u003e\n\n\u003cli\u003eSwitchable insert points when used with A-D card\u003c\/li\u003e\n\n\u003cli\u003eCalibratable, per-channel six-segment LED peak-level meters\u003c\/li\u003e\n\n\u003c\/ul\u003e\n\n\u003chr noshade\u003e\n\n\u003cp style=\"text-align: left;\"\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003eMicrophone Inputs\u003c\/p\u003e\n\n\u003cul\u003e\n\n\u003cli\u003eAll measurements taken at maximum gain unless otherwise stated, Rs = 150Ω.
