The DCI 4/300 DriveCore Install Analog Series from Crown Audio is a 4-channel amplifier capable of producing 300 watts of output per channel and works with 2, 4, 8, and 16 Ohms or 70 or 100 Vrms. Channels can be bridged for powering higher power applications such as a subwoofer. The 4/300 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 -80 dB.

The front panel of the 4/300 provides a series of system indicators, including level and signal, ready, clip, thermal, and fault alerts for quick visual monitoring of the system. The unit can be integrated into a control system for powering on and off as well as engaging its sleep mode for saving energy when not in use. The 4/300 is 2U rackmountable and ships with 4 male connectors for wiring and an IEC power cord.
