Vintage Klein & Hummel UE1000 Discrete Program Equalizer Pair serial# 3216, 3217

Klein & Hummel UE1000 Discrete Program Equalizer Pair serial# 3216, 3217. This beautiful pair of program equalizers from the 1970s are mounted in individual wooden racks. The Klein & Hummel UE1000 is one of the most highly sought after program equalizers, second ony to the venerable Pultec EQP1. The UE1000 offers an unusually varied set of possibilities for influencing the frequency response, amplitude and slope of the response curve within the audio spectrum. Amplitude and slope controls are either pushbutton or step controls, permitting simple reproducability at any setting at any time. The UE1000 features unitized construction throughout. Each set of pushbuttonsmounts its own amplifying stages, resistor and condenser, and gets its power from a power distribution strip atop the power supply which forms the back of the entire unit. There are seven such subassemblies in all including the balanced input and output stages. Each building block makes it possible to alter the frequency response curve in frequency, amplitude simultaneously and independently from one anpther at eight distinct segments of the audible range.
