Official description
The Model 583E is a 500 series tube microphone preamp. It features the same amplifier stage found on the 583S including the Jensen JT-115k input transformer coupled with an ultra-clean transformer-less three-band EQ section with fully sweeping frequency controls and cut/boost settings of +/- 8dB. The EQ can run as an integrated EQ serving the preamplifier or separate as its own autonomous module where both units run independently.
