from the hand wound transformer and up to 40dB from the amplifier, an extremely low noise floor and super wide bandwidth 10Hz to 200kHz. This pre amp design is the cornerstone of Focusrites signature warm yet transparent sound and is a point of reference for any discerning audio professional.In addition, the input stage provides enhanced control and creativity allowing you to switch between four carefully selected input impedance settings. The original ISA 110 setting is supplemented by three further impedance settings to either perfectly match the pre amp with any microphone and maximise level, or use different settings creatively to shape the sound of the microphone being used. Should the need arise to place extra processing in between pre amp and conversion, insert points are also featured on every channel.Protecting the ADC, the Soft Limiter opto circuit is a new design from Focusrite, entirely preventing any digital overs, whilst minimising the undesirable distortion that standard limiter circuits often generate.Finally, the new ADC embodies cutting edge conversion technology, encompassed within pristine Focusrite circuitry, providing eight conversion channels of the highest quality, at frequency rates of up to 192kHz. Running at 96kHz allows for up to 16 2 x 8, parallel simultaneous digital outputs in addition to the four main analogue outputs. Digital output options include dual AESEBU, SPDIF and dual ADAT lightpipe. Full digital metering is provided fo
