LaChapell Audio 583E 500-series Tube Mic Preamp with EQ

Boutique-quality, transformerless vacuum-tube preamp with independent EQ for the 500 format

More than just a LaChapell 583s preamp with EQ, the 583e is more than the sum of its parts. The 583e’s preamp and EQ sections can be operated independently or together, which means that one of two rack spaces the LaChapell 583e module takes up in your 500-series lunchbox does more than bring you one of the best-sounding tube preamps in the business. Big, spacious, full of air, the LaChapell 583e preamp also features an ultra-clean, transformerless three-band EQ section with fully sweeping frequency controls and cut/boost. The equalizer section of the 583e can run as an integrated EQ (serving the preamplifier) or separate as its own autonomous module independent of the preamplifier. The LaChapell 583e is like having a LaChapell 583s and Model 503 EQ (with a little something extra) in only two rack spaces.
