983S MK2 TUBE MIC PREAMP

2 Channel tube mic pre and instrument preamp
STREET PRICE: $1999.99

The LaChapell 983S MK2 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 MK2 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, the 983S MK2 features high and low pass filters with selectable roll-off frequencies, channel mute, front panel Hi-Z input, pad and polarity switches.

    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.

  • Lachapell audio pad icon

    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.

983S MK2 REVIEW AND QUOTES

“I’ve been using LaChapell Audio mic preamps for a number of years.  The one word that comes to mind that’s consistent throughout the line is “versatility.”  All of the mic preamps (992, 983, 583) have 2 distinct flavors based on where they interjected the 20 dB pad.  Without the pad engaged you get a big, open, warm, full of transient sound that’s lovely on just about everything.  With the pad engaged you get a tight, slightly compressed, less transient sound that works on everything else.  They are definitely my go to mic preamps.   When I don’t use them It’s just because I don’t have enough of them.” –  Mark Polack, Mixer/Engineer/Bassist/Programmer/Songwriter (Kenny Loggins, Richard Marx, Paul Carrack, John Oates, Reggie Young, Mark Knopfler, Felix Cavaliere)
