2 Channel tube mic pre and instrument preamp
The LaChapell 983S is a two channel tube mic pre featuring the innovative True48™ dynamic phantom power supply. True48 improves the performance of your condenser mics. Current 48V supplies dip in voltage as the source load changes (such as periods of high transients on many mics). True48 evens out the voltage supply, giving mics greater headroom, quicker transient recovery and a smoother less distorted response.
Each channel on the LaChapell 983S features a Cinemag input transformer, an ECC83/12AX7 vacuum tube, Jensen output transformer and Burr Brown & THAT Corporation line drivers. Each component in signal path is of the highest quality, carefully selected to sound beautiful and last long.
This mic pre is capable of stunning clean tones and harmonically rich driven tones. Exceptional on nearly any source, channel mute, front panel Hi-Z input, pad and polarity switches.
983S PRODUCT FEATURES
DUAL DRIVE KNOBS
The Dual Drive knobs on the 983S mic pre 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.
TRUE48 Dynamic Phantom Power
True48 is a dynamic phantom power supply that provides a steady power supply for your condenser and active microphones. Standard phantom power supplies often do not deliver enough power for today’s microphones. True48 ensures your mics get the power they need which results in higher headroom, quicker transient recovery, and smoother response.
PAD SWITCH FOR MORE TONAL OPTIONS
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.
BEST IN CLASS PERFORMANCE
Everything in the 983S mic pre is designed to be best in class. Every component, transformer, wire and tube has been meticulously selected for performance and longevity.
LOW NOISE AND OUTPUT IMEDANCE
The ultra low output impedance of the 982S mic pre means you can run long cables from the stage to front of house or from studio room to studio room. The ultra low noise means you can record any source with confidence that you are only recording what you WANT to record.
FRONT PANEL HI-Z INPUT
The front panel Hi-Z input allows you to plug a bass or other instrument directly into the 983S. As an instrument front end, the 983S allows for natural tube compression and harmonics to any input source.
