Summit Audio MPC-100A

Summit Audio MPC-100A

The Summit MPC-100A is a single channel tube preamplifier and tube compressor/limiter all in one unit, accepting line, microphone, and Hi-Z input signals. The preamplifier provides a warm yet crisp vacuum tube tone. The compressor/limiter section has very fast attack times, making it ideal for optimizing signal prior to entering the digital domain. In addition to having superb sound and a user friendly interface, the MPC-100A has the robust build quality consistent with the Summit Audio family of products.

Vocals and bass really shine with the MPC-100A, the Jensen mic transformer and tubes working in synch to lend a detailed sound with harmonically complex overtones. The ultra-fast compressor makes it ideal for drums, especially kick and snare, to tame those transients yet keep the body rich and full. The MPC-100A features variable impedance (loading) on the Hi-Z input so passive guitars and bass pickups have a whole new level of tone control. Increase the loading for a minimum of resistance and the open, airy sound of your pickups working unimpeded. Turn the impedance control down and listen to the high frequencies start to attenuate in a musical way and the low frequencies get tighter and more focused as the pickups are loaded. And with three separate gain controls, two driving vacuum tubes with a master output level, you have endless tonal variations for whatever sound you need.
