LaChapell Audio 583e 500 series tube microphone preamp with integrated EQ front image
LACHAPELL AUDIO 583E
500 Series tube Mic preamp with EQ
MSRP: $1995

The Model 583E is a 500 series tube preamp with an EQ section that can function independently as two separate modules. Incredible on microphone source, it also features a Hi-Z input for instruments. The 583E features a single channel vacuum tube preamplifier with LaChapell Audios proprietary TrueTube™ technology. TrueTube delivers 250V to the tube, properly powering it so that it operates at its full potential and is not starved for power.

In addtion, the 583E features an ultra-clean EQ section that can follow the preamp or operate as a separate module.

PRODUCT FEATURES

  • Lachapell audio 500 series modules icon

    FIRST 500 SERIES TUBE PREAMP

    The 583 series was the first ever tube preamp for the 500 series. It is extremely versatile, allowing a wide range of sonic options from clean to harmonically rich. It’s great for use on almost any source with almost any mic.

  • Lachapell Audio dual drive icon

    DUAL DRIVE KNOBS

    The Dual Drive knobs on the 583S provide an incredible array of tonal options. The input knob drives the input to the first vacuum tube preamp and the second knob drives the input to the output tube preamp. Together, you can dial in sounds from pristine to warm and harmonically rich.

  • 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.

  • 583E preamp with switchable EQ icon

    SPLIT MODULE VERSATILITY

    The clean and transparent EQ section on the 583E can operate immediately following the tube preamp section, or as its own separate module. When combined, the output of the preamp and EQ appears on the “Preamp Side” XLR outputs. When independent, the in and out of the “EQ Side” operate separately.

    BOUTIQUE QUALITY TRANSFORMERS

    With a Cinemag input transformer and Jensen output transformer, the 583S maintains a boutique quality signal chain from I to O. Every aspect of the 583S has been designed for sonic quality that will last for generations.

  • lachapell audio hi-z input icon

    FRONT PANEL HI-Z INPUT

    The front panel Hi-Z input allows the 583S to be used as an instrument preamplifier. When a 1/4″ jack is inserted into the Hi-Z input, the 583S switches into instrument mode, bypassing the input transformer so the instrument accesses the tube directly.

SELECTED QUOTES AND REVIEWS

“I use the LaChapell 583E mostly for overheads and acoustic instruments. I use a stereo ribbon mic on overheads The 583E has a very smooth top end and with the EQ I can add just the right amount to brighten up the very top without it sounding harsh, the high end stays nice and silky. It also is very quiet when used on acoustic guitars with a ribbon mic. Overall a very clear and open mic pre.” Mike Wagener of Wireworld Studios

The microphone preamp side of the 583E is identical to the 583S. Please see the reviews on the 583S MK2 page.
