The Boss CP-1X Compressor uses the company’s Multi-Dimensional Processing (MDP) technology to analyze input signal, allowing a player enhanced dynamic control of their sound using its four-knob interface to adjust Level, Attack, Ratio, and Compression. Its 18-volt input circuitry provides ample headroom, and its 16-segment gain reduction indicator displays the amount of compression being applied to the signal. Visit boss.info/us.
