Designed, engineered, and manufactured for system integrators requiring advanced features and flexibility, the Crown Audio DCi 4|600 DriveCore Install Analog Series is an 4-channel amplifier capable of producing up to 600W of output per channel and works with 2, 4, 8, or 16 ohms, and 70 or 100 Vrms. Channels can be bridged for powering higher-power applications such as a subwoofer. The DCi 4|600 also has channel-independent high- or low-impedance output that is selectable from the rear-panel DIP switches. This allows you to integrate the amplifier into a variety of different setups. Each of its 4 channels additionally features independent attenuators with an attenuation range from 0 to -95 dB.
