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. With a total of eight vacuum tubes the 992 will awaken your ears with its warm melodic character and rich low-end response.
But, what makes the 992 such a powerful preamp is the level of control the user has over both the input and output stages. Allowing the user to actually throttle gain in or out of either the input stage (for loads of character) or the output stage (for a more clear, transparent response) by way of fully variable potentiometers secures the 992 as one of the most flexible vacuum tube preamps available in today’s market.
Dual Drive Knobs
The Dual Drive knobs on the 992EG provide an incredible array of tonal options. The input knob drives the input to the first vacuum tube and the second knob drives the input to the output tube. Together, you can dial in sounds from pristine to warm and harmonically rich.
Versatile tone with pad switch
The pad switch not only provides a -20dB gain reduction for high input sources, it also works with the Dual Drive knobs to create color and headroom options. Engage the pad and dial in warm tones with lots of headroom.
Front panel Hi-Z input with auto-switching
The front panel Hi-Z input allows you to plug a bass or other instrument directly into the 992EG. As an instrument front end, the 992EG allows for natural tube compression and harmonics to any input source.
Illuminated VU Indicators
The Illuminated VU knobs make it easy to see what the 992EG is doing. It runs from a separate signal chain so there is no interference with the amplified signal.
Heavy duty boutique grade chassis
The 992EG chassis and front panel are incredibly robust ensuring your 992EG is not just a piece of gear for now, but one that will be handed down for generations.
