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\n\u003cp\u003eUp to 60dB of gain is available, with a further +20dB of continuously variable trim, providing a huge 80dB gain range.
