The ISA428 features four classic, transformer-based microphone pre amps with switchable impedance and direct Instrument Inputs are combined with an optional eight channel 192kHz ADC. An all-new, Soft Limiter circuit precedes the A/D, providing the perfect path into any DAW, Digital Console or direct to Hard Disc Recorder.
The input stage provides enhanced control and creativity allowing you to switch between four carefully selected input impedance settings. 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 to use different settings creatively to shape the sound of the microphone being used. Should the need arise to place extra processing between pre-amp and conversion, insert points are also featured on every channel.
