LaChapell 583E Tube EQ Mic Preamp
The LaChapell 583E is a tube mic pre with EQ that works with any 500 series chassis. The 583E tube mic pre has an EQ section that can function in series with the preamp or independently as a preamp and an EQ. The 583E tube mic pre features a single channel vacuum tube preamplifier with LaChapell’s 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 like other tube designs for the 500 series chassis. Cinemag input transformers, Jensen output transformers and other high quality components have been carefully selected to ensure the signal chain is not compromised.
In addition to the preamp, the 583E features an ultra-clean EQ section that can follow the preamp or operate as a separate module. Address either of the two XLR inputs on a 500 series chassis to access either the preamp or the EQ or both in series.
The EQ draws from the LaChapell 503 500 series module and features the same very low distortion signature with minimal phase deviation. Perfect for tracking or mixing, the 583E tube mic pre with EQ is great on any source when tracking, or an outboard EQ for mixing.
- 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.
- DUAL DRIVE KNOBS
The Dual Drive knobs on the 583E provide an incredible array of tonal options. Favoring the input knob will increase the signal going into the tube, resulting in more harmonics and overall distortion. Favoring the output know yields a very clean signal. Together, you can dial in sounds from pristine to warm and harmonically rich.
- 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.
- TWO MODULES IN ONE
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. Use as a complete channel strip or as two separate 500 series modules.
- BOUTIQUE QUALITY TRANSFORMERS
With a Cinemag input transformer and Jensen output transformer, the 583E maintains a boutique quality signal chain from I to O. Every aspect of the 583E has been designed for sonic quality that will last for generations.
- FRONT PANEL HI-Z INPUT
The front panel Hi-Z input allows the 583E to be used as an instrument preamplifier. A front panel switch allows the user to alternate between the front panel Hi-Z input and the built in inputs on the 500 series chassis.
