LaChapell 583s 500 Series Tube Mic Preamp CLOSEOUT SALE
THIS IS THE ORIGINAL TWO-SLOT 500 SERIES VERSION OF THE LACHAPELL TUBE MIC PREAMP. TEN SPACE RACKS ARE CHEAP - SAVE BIG ON THIS DISCONTINUED VERSION!
The LaChapell Audio Model 583s is the world’s first vacuum tube preamplifier designed for the 500 series lunchbox audio format.
Based largely on our 992EG, the 583s is the perfect solution for those looking to add that extra warmth and character to their lunchbox with versatility that only a properly powered 12AX7 vacuum tube can provide.
Using multiple internal DC/DC converters, the 583’s 12AX7 tube enjoys proper power for both plate (250 volts) and filament (12 volts). Unlike some other tube preamps for the 500 series, we do not starve the tube of voltages in any way. And, since this all occurs within the 583 module, there is no worry of harming your 500 series power supply.
COMPONENTS The 583s has the CineMag CMMI-10 microphone input transformer and Jensen’s best line output transformer; the JT-11. Typical preamplifier features are available as well including 48v, a 20 dB pad and polarity reverse. It also has an auto-switching, transformer-less Hi-Z input for instruments.
CONTROLS In operation, the user has individual control over the input and output gain stages via 41-position potentiometers. This, like its 992 older brother, provides total flexibility to explore the 583s’ broad sonic pallet; enhancing its versatility for all of your recordings.
