Uses ECC81 double triodes for both the audio amplifier and sidechain driver.
Features heavy custom transformers (iron) throughout the signal path to provide a "thick" and "3D" analog sound. Key Plugin Features
Employs six DS62 germanium crystal diodes for floating gain reduction. NEOLD U17 [WiN-OSX]
A proprietary knob that simultaneously adjusts the compression ratio and knee, ranging from transparent to aggressive.
The original hardware was custom-built by in Hamburg for the post-war NWDR (Northwest German Broadcasting) network. Only a few dozen units were ever produced, primarily used to boost signal-to-noise ratios in AM radio transmissions. It is famously documented in the "Braunbuch" , an anthology of technical descriptions for German broadcasting hardware. Technical Architecture Uses ECC81 double triodes for both the audio
Provides automated settings for Attack and Release times.
A soft-clipping stage that precedes the compressor. Density controls the clipping intensity, while Emphasis targets specific frequency ranges for saturation. It is famously documented in the "Braunbuch" ,
The U17 is known for its unique hybrid circuit design that combines vintage and early solid-state technologies:
