Each channel has the option of mic or line inputs, while inputs 1-4 also feature instrument inputs on the front panel. 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.\u003c\/p\u003e\u003cp\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 features variable cut-off frequency between 16 and 420Hz. 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.\u003c\/p\u003e\u003cp\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\u003ch2\u003eISA 828 MkII at a Glance\u003c\/h2\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eGain Range\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e0dB to +30dB (30-60 switch disabled) and +30dB to +60dB (30-60 switch enabled) in 10dB steps, with an additional +20dB of continuous trim\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eInput Impedance\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eLow = 600Ω, ISA 110 = 1400Ω, Med (Medium) = 2400Ω, High = 6800Ω\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMax.
