Two great included features are the AGC and Sub Harmonic Synthesizer. The AGC allows you to set a target output level and the circuit will raise or lower the level to meet that target. The Sub Harmonic Synthesizer allows you to create either a deep very low body or a lighter and more booming extra body to the original sound.
The DS-CP22 provides 7 bands of parametric equalization with High/Low Pass filtering. Each EQ filter can be easily adjusted to a specific frequency, and the Q selected with simple Bell curve adjustments from 0.05-3.00. The DS-CP22 can store up to 32 presets.
Whether traveling on the road with the band or in a fixed installation, the DS-CP22 has the features needed to aid in sound improvement.
