SUMMIT AUDIO / MPC-100A

Hybrid mic preamp with tube preamp and compressor (with VU meter) DI loading control! We have earned outstanding trust from professional users.

By integrating the microphone preamplifier and comp / limiter, the MPC-100A eliminates extra wiring and contacts, and can output the sound of the tube clear without turbidity. The mic preamplifier section also supports lines, with 48V phantom power, 2-position switchable PAD (-15dB / -25dB), and high-impedance loading control. Furthermore, the attenuator adopts a step type and has a clip indicator. The compressor section is equipped with threshold, release and gain controls, and the attack and release time can be switched between FAST / MEDIUM / SLOW. In addition, a level / gain reduction switchable meter, clip indicator, and link / bypass switch are also provided, so that operation can be checked smoothly. With substantial sound and specs, and most importantly, high cost performance, the MPC-100A is being used as a global hit in studios and live scenes around the world.
