Product Description

500DT DUAL TOPOLOGY PREAMP
500 Series Dual Topology Tube and Solid State Preamp


The LaChapell Audio 500DT dual topology preamp is a 500 series microphone preamp that features two separate topologies or amplification paths. When the blend knob is fully to the TUBE side, the signal will pass through a transformer before being amplified by a TrueTube™ powered 12AX7 vacuum tube. TrueTube is LaChapell Audio’s proprietary method of supplying a full 250V to the vacuum tube so you get loads of clean tube gain.

When the blend knob is turned fully to the OPAMP side, the signal passes directly to a solid state preamplifier. This input is transformer-less and will provide clean gain with exceptionally low noise Placing the blend control anywhere between the two extremes will “blend” the two topologies for a wide variety of tonal options.

PRODUCT FEATURES

  • Lachapell audio 500 series modules icon

    500 SERIES MIC PREAMP

    An extremely versatile tube AND solid state mic preamp in the 500 series format based on the legendary 583S.

  • lachapell audio truetube power 250V icon

    TRUETUBE™ 250V POWER

    TrueTube™ technology supplies both the plate and filament of the tube with the proper voltages they need to access the full characteristics of the tube. Other tube preamp designs cannot supply the needed 250V and don’t have the headroom or harmonics that characterize that classic tube sound.

  • lachapell audio hi-z input icon

    FRONT PANEL HI-Z INPUT

    The front panel Hi-Z input allows the 500DT to be used as an instrument preamplifier. When a 1/4″ jack is inserted into the Hi-Z input, the 500DT switches into instrument mode, bypassing the input transformer so the instrument accesses the preamp directly.

  • Lachapell Audio dual drive icon

    DUAL GAIN KNOBS

    The Dual Drive knobs on the 500DT provide an incredible array of tonal options. The input knob drives the input preamp and the second knob drives the output for sounds ranging from pristine to gritty.
