Heritage Sound times four.

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.

Accurate LED meters for every channel: Clear metering designed to catch even the fastest and most elusive of transients.

About This Product

Description:

Heritage Sound times four. Focusrite’s ISA mic preamps can be traced back to 1985, when console designer Rupert Neve was asked by Sir George Martin to create new modules for the console at AIR Montserrat. The modules he created included the legendary ISA110, on which all ISA microphone preamps are based. With their characteristic Lundahl LL1538 input transformer, along with one concession to modernity – variable input impedance – ISA mic preamps are very much the same as they were 30 years ago. But today, instead of solely gracing the consoles at AIR, ISA mic pres are at the heart of hundreds of hits made in leading studios and by leading engineers, artists and producers, across the world.
