1.The Shell has similar bandwitch as but contains significant improvements in structure, mechanical, and operation.Display and MCU are now mounted on the same board (mainboard) to avoid using -board pin-headers. Feedback from usres have shown that soldering on the pin-headers are often problematic for many beginners. Analog channel is placed on a separated board which contains most user install parts. This brings in better separation between analog and digital circuits. 2.The Shell comes with full enclosure. The front panel and top/bottom brackets are flexiable for easy user modification. 3.Rotary encoder has been added. It makes parameter adjustment much quicker and easier. 4.The sensitivity of Shell has been extended in both directions and is higher and than . It reaches 5mV/ --- 20V/ while is only 10mV/ --- 5V/.
