Apogee has taken a high-end design approach to the mic preamps in the Connect Series I/O modules to achieve the best performance of any audio interface. With Apogee’s Advanced Stepped Gain Architecture™ Connect Series interfaces feature a mic preamp circuit that is dynamically optimized at different gain settings to provide superior bandwidth, ultra low noise and nonexistent distortion across an expansive gain range of 0-72 dB.
The Advanced Stepped Gain Architecture™ functions a bit like a finely tuned race car with many gears: optimal circuit performance (low noise and low distortion) is maintained regardless of the gain required. Digitally-controlled analog switches “shift the gears” of the circuit at each gain setting to ensure the best sound and performance. Other mic pres struggle at the extremes of gain – they are essentially “two-gear” circuits.
