Description:
The NE72 is a classic circuit based on the legendary British preamp from the 1980s. As in all IGS Audio devices, the NE72's input is transformer balanced. It is a pure A class circuit with the audio path reduced to minimum （ultra-short connections between elements）. The construction consists of two steps of gain. The Gain and Output knobs drive the individual steps. The input is a LL1538 Lundahl transformer, output is a Carnhill. It is a 2U unit.
Typical usage:
• Great microphone preamp with or without phantom power
• Handy for vocal and guitar on stage
• Great for high level signals like snare or kick

个人评语：十分复古的话放~各种拨弄开关~~很酷，但笔者没有上手过~但这个品牌在业内比较知名~可以一试~最好是能问店铺有没有实际的测试声音~
