The Klein and Hummel UE400 is a vintage stereo equalizer from the mid-1970's.
The UE400 features 3 EQ bands that span the entire frequency range plus high and low shelving. In use, this unit proves great for drum bus, master insert, and coarse work in general where you need an old school, non-smooth personality. Each channel has three identical full range parametric EQ sections so each section covers the full audio band from 15 HZ to 20Khz in three switchable ranges including variable Q from broad to sharp.
