The MPC-100A is a single channel tube preamplifier and tube compressor/limiter all in one unit, accepting line, microphone, and Hi-Z input signals.

Harmonically rich sound
Three tube gain stages allow you to create realistic and natural harmonic tone that can help make the often 2 dimensional sound of digital come to life.

Straight forward operation
Clean lines and dedicated, simple to use controls are the key to a great piece of gear. The MPC-100A is an intuitive extension of any studio environment.

Superb dynamics
The MPC-100A features one of Summit's fastest selectable compressors. Perfect for tracking difficult, transient signals, it has smooth and natural harmonics as you would expect from Summit Audio compression.

Hand-crafted in the USA
Each piece of Summit gear is meticulously crafted by hand in our shop using only the best quality components and attention to detail. Quality components and engineering know-how are the critical element to the sound and longevity of audio gear.
