• A modern classic with the stamp of Rupert Neve! The ISA 428 Pre Pack is the perfect multichannel front end for any professional DAW. It features 4 classic Rupert Neve-designed transformer-based pre-amps with switchable impedance and direct instrument inputs. An optional 8-channel 192kHz ADC, preceded by the all new proprietary Soft Limiter circuit, provides the perfect path into your Pro Tools HD system.
  
  The benefits of the pre-amp'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). This pre-amp design is the cornerstone of Focusrite's signature "warm-yet-transparent" sound and is a point of reference for any discerning audio professional.
  
  In addition, the input stage provides enhanced control and creativity allowing you to switch between 4 carefully selected input impedance settings. The original ISA 110 setting is supplemented by 3 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, insert points are also featured on every channel.
  
  Protecting the ADC, the Soft Limiter opto circuit is a new design from Focusrite, entirely preventing any digital overs while minimizing the undesirable distortion that standard limiter circuits often generate.
  
  Finally, the new ADC embodies cutting-edge conversion technology encompassed within pristine Focusrite circuitry, providing 8 conversion channels of the highest quality at sample rates of up to 192kHz. Running at 96kHz allows for up to 16 (2 x 8, parallel) simultaneous digital outputs in addition to the 4 main analog outputs. Digital output options include dual AES/EBU, S/PDIF, and dual ADAT lightpipe. Full digital metering is provided for every channel, alongside new moving-coil peak meters designed to catch even the fastest of transients.
  
  A second analog unit can be connected utilizing the 4 extra ADC input channels on the rear of the unit containing the optional ADC. This makes full use of the 8 channels provided on a single optional ADC and expands your front-end capacity from 4 pre-amps and 8 digital outputs to 8 pre-amps and 8 digital outputs.
  
  With classic pre-amp technology, custom Focusrite input and limiting circuits, and the very best in A/D conversion technology, the ISA 428 Pre Pack raises the bar for multichannel recording solutions. Equally, it can be used as an additional set of high-quality pre-amps for any analog or digital console or hard disk recorder.
