Four ISA series transformer-based preamps
ISA series mic preamps have been the producers’ choice on countless hit records over the last two decades.
Eight-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.
Selectable impedance
Ideal for mic matching or extended microphone creativity. Settings include the ‘Vintage ISA110’ setting, providing the original Focusrite signature sound.
Four front panel instrument inputs
Instant access on the front fascia - no separate DI box required.
Dedicated analogue insert points
Switchable insert points are featured on every channel, allowing routing (between preamp and output) through additional external processing.
Variable high-pass Focusrite filter
Provided on every channel, this is the same filter as featured on the original ISA428.
Accurate LED meters for every channel
Clear metering designed to catch even the fastest and most elusive of transients.
