LaChapell Audio 992EG Mic Pre (Used) – No Longer Available

All-tube mic preamplifier

Product Description

The LaChapell Audio Model 992 is a two channel fully balanced all-tube preamplifier and instrument input amplifier. Meticulously hand assembled, every aspect of the 992 speaks of our dedication to quality of sound and solid, robust construction.

Utilizing a total of eight vacuum tubes promises that the 992 will absolutely awaken your ears with its warm melodic character and rich low-end response. With the 992 you have the option of choosing between two unique input topology configurations- TLS or EG. The 992 EG (extended gain) utilizes a Jensen JT-115k transformer and the timeless 12AX7/ECC83 vacuum tube, and is able to provide a generous >74dB of raw internal gain. With over 40dB of gain deployed to the input pot alone your ability to explore the sonic richness of each stage becomes even more dramatic than that of the 992 TLS. The direct instrument input (Hi-Z) utilizes a high performance Cinemag direct transformer which feeds the balanced differential amplifier input.

From there the signal reaches the cross-coupled push-pull output stage where we’ve place two 12AU7 tubes in parallel along with the Jensen JT-11 transformer to balance the outputs. The balanced class-A circuitry used throughout this amplifier provides twice the headroom of single ended designs as well as low noise performance. With the use of four tubes per channel, the 992 easily delivers performance well beyond the limits of audibility.

In operation, the user has individual control over the input and output gain stages of each channel. This provides uncommon flexibility to delve into the 992’s broad sonic pallet making it one of the most versatile preamplifiers in any environment. Push the inputs hard and capture that elusive air that can only come from fully balanced tube gain. Or, pull the inputs back and favor the output stage for a cleaner, more linear signal - the choice is yours. Output signal strength is easily monitored through an isolated Sifam back-lit VU meter. There are also five illuminated toggle switches per channel for Meter On/Off, 48v (Phantom), -20db input pad, phase reverse and Mute.

All of this is housed in a chassis that is built like a tank. Designed with reliability and “on the road” stamina as a requirement, we start with high grade aluminum stock milled to a sturdy 1/4” front panel with chip resistant powder coating for the finish. All internal components are well secured using PEM type fasteners and tie-downs. And, of course, ultra-premium components are used throughout: 3/4w Vishay resistors, ASC caps, sealed premium relays ... Our goal is to communicate a sense of robust sturdiness when interfacing with the 992. Each unit is assembled by hand with much care and attention to detail with the hope of preparing it to be the next center piece for any professional recording or broadcast environment. We encourage you to try one and experience for yourself what we think is a new standard of pure tube amplification.

I would like to thank VK for the wonderful sales assistance, service and prices. This was my first purchase with you and it won't be my last. I only wish I'd discovered you years ago!

I had two Grammy wins this year - Ray LaMontagne & Carolina Chocolate Drops. Both made with help from Vintage King!

In almost 20 years in Pro audio buying, never did I receive a unit so well packed and exactly as described. Works flawlessly. The whole process has been so smooth. I will never hesitate to do business with you guys in the future and will recommend you to everyone I know.

This was my first experience buying something from Vintage King (although I surf the "used" categories on the website frequently!), and, despite being on the other side of the world, I had absolutely no trouble and everything went very smoothly.
