Four-channel amplifier for installed sound

The Crown DCi 4X300 DriveCore Install is a four-channel power amplifier rated at 300 watts per channel. It is built for permanent installations in venues, houses of worship and commercial facilities where consistent performance and rack-density matter. The unit occupies 2 rack units and weighs 29 pounds.

DriveCore integration and voltage flexibility

Proprietary DriveCore circuitry combines hundreds of discrete components into a single chip, reducing power draw and improving reliability. Each channel can be independently switched between low-impedance and 70 V or 100 V direct-drive operation, allowing mixed speaker loads without external transformers. Sleep mode draws less than 1 watt and activates after 30 minutes without signal or via the AUX port.

Analogue-only input and fixed power ratings

The amplifier accepts analogue signals only; no digital audio networking or DSP is included. Output power is fixed at 300 watts per channel into the rated load, with no 600-watt option in this model. Protection circuits guard against shorts, DC offset, thermal overload and high-frequency stress, but the topology does not support bridge-mono or higher-voltage configurations beyond the stated 100 V direct drive.

Questions about this item

Will the internal fan or dust filters need periodic cleaning on this amplifier?

The unit uses Crown's DriveCore integrated circuit which consolidates hundreds of discrete components into a single chip, improving reliability and reducing the number of moving parts that typically require maintenance.

What thermal protection activates first during continuous high-output operation?

TLC Protection monitors temperature and applies intelligent gain reduction to maintain operation when excessive heat is detected, preventing thermal shutdown.

How much power does the amplifier draw from the mains when left on all day with no signal?

After 30 minutes without an input signal, Auto Standby engages Sleep mode where power consumption drops below 1 watt, and Remote Power Off via the AUX port can also trigger this state.
