| The ISA 428 Pre Pack is the perfect multi-channel front end for any professional DAW and includes four Focusrite transformer-based pre amplifiers with switchable impedance and direct instrument inputs. The benefits of the pre amplifier's topology include superb common-mode rejection, an excellent overload margin and, with its shared gain structure (20dB from the hand-wound transformer and up to 40dB from the amplifier), an extremely low noise floor and super-wide bandwidth (10Hz to 200kHz). |

Features
- The input stage of each preamplifier allows the choice of four carefully selected input impedance settings, which provides enhanced control and creativity. The original ISA 110 setting is supplemented by three further impedance settings to either perfectly match the pre amp with any microphone and maximize 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, the ISA 428 Pre Pack provides insert points on every channel.
