The LaChapell Audio Model 583S was the world’s first vacuum tube mic preamp in a 500 series module. It is still the only 500 series module to properly power the tube with 250V of TrueTube™ technology. Unlike some other vacuum tube mic 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.
Every component on the LaChapell 583S MK2 was carefully selected for sonic perfection from the Cinemag input transformer to the Jensen output transformer.
With dual drive knobs to separately drive the input and output, the 583S provides total flexibility to explore a broad sonic palette enhancing its versatility for all of your recordings. Leaning on the input stage, the 583S MK2 delivers vintage style tube warmth. The more you drive the input, the more harmonics are introduced. Backing off on the input but increasing the output results in gorgeous clean tones with some weight provided by the Cinemag and Jensens transformers.
The LaChapell 583S MK2 is an essential 500 series module for the modern professional and project recording studio.
