Standing for 'Input Signal Amplifier', the ISA range was born out of the original Focusrite Forte console of the late 80's. This console was, and still is, considered by many as sonically the finest console ever built. The core modules from this console live on with Focusrite's current range of ISA products, which have in themselves also become recording classics, and the choice of the world's finest producers and engineers.
