isa-sought-after-sound-2400x2400

Classic mic pre with independent DI

Featuring a rugged, portable all-metal enclosure, ISA One combines the classic Focusrite microphone preamp with a flexible, independent DI channel and optional 192kHz precision A-D conversion. At the heart of the ISA range is the microphone preamplifier with its Lundahl input transformer – essentially the same circuit, based on the original ISA 110, that has been used for 30 years in successive Focusrite designs. The input transformer imparts a special character to the sound that can't be truly emulated in any other way, while the modern twist of variable input impedance allows for a new degree of flexibility. Whether you're an artist, engineer or producer, you'll appreciate the versatility of the ISA One, with its front-panel DI input. The DI includes low/high impedance switching and an amplifier output, and its own feed to the optional A-D converter and separate rear-panel XLR output. pro-bx-console-focusrite-2400-1350

Brainworx bx_console

The Focusrite Studio Console reborn in your DAW

The Focusrite Studio Console defined countless hits of the 80s and 90s, thanks in large part to its ISA 110 Equaliser and ISA 130 Dynamics Modules. Brainworx's bx_console Focusrite plug-in brings you stunningly accurate emulations of both in a single plug-in, perfectly capturing the famously warm, open sound of two of the most revered pieces of studio hardware ever made.
