Or you can experiment and bring out just the qualities you want.\u003c\/p\u003e\n\u003cp\u003eIn addition to the mic inputs, there are four front-panel instrument inputs making the ISA428 Mk II ideal for overdubs in the control room with no need for a DI box. On the back: four line inputs and switchable insert points on each channel to allow routing via external signal processors. There's also a versatile, vintage design variable high-pass filter to control what's going on at the bass end.\u003c\/p\u003e\n\u003cp\u003eAnd finally... accurate, 6-LED meters to tell you exactly what's going down. Optionally available for the ISA428 Mk II is a precision eight-channel A-D converter with 122dB dynamic range and superb jitter performance — ideal for simple interfacing with your DAW (sold separately).\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eFour ISA series transformer-based preamps — ISA series mic preamps have been the producers' choice on countless hit records over the last two decades.\u003c\/li\u003e\n\u003cli\u003eEight-channel optional A-D converter — Four additional A-D converter inputs allow eight channels of high quality conversion, with a dynamic range of 122dB and jitter performance below 250 picoseconds.\u003c\/li\u003e\n\u003cli\u003eSelectable impedance — Ideal for mic matching or extended microphone creativity.
