Crown Audio DCi8x300 8-channel Analog Power Amplifier Features:
- True Rack Density - Power points of 300W or 600Win 2-/4-/8-channel configurations, all in a 2 Rack Unit form factor.
- More channels in one box allow smaller infrastructure rooms that can reduce operational costs while giving you the utmost in installation flexibility.
- Direct Drive Constant Voltage - Save money by using smaller gauge wiring to drive the speakers using either 70Vrms or 100Vrms.
- With no need for a step-up transformer at the output, the DCi produces higher audio quality much more efficiently.
- Channel Independent Hi-Z/Low-Z Selection - Drive either one or two speakers in low-Z mode, or literally hundreds of speakers in high-Z mode.
- This means better design flexibility since DCi powers all loads on a channel-by-channel basis.
- Bridgeable Channel Pairs - The DCi Series channels are bridgeable even in 100Vrms mode.
- Which means even more adaptability for higher power applications such as subwoofers.
- Remote On/Off Interface - Save power by integrating the amplifier into a control system so you can easily turn it on and off.
- Efficient Cooling Design - Highly efficient internal cooling fans provide airflow to the most heat-generating parts.
- Incorporating the fans into the amplifier brick design maximizes cooling while minimizing wasted energy and noise.
- Advanced Power Factor Correction (PFC) Universal Power Supply - The most advanced power supply in an installation amplifier.
- Delivers power more efficiently in almost any condition than anyone else, resulting in less power dissipated and less heat in your racks.
- Exclusive DriveCore Technology - combines hundreds of discrete circuits into one chip.
- This makes for better performance, lower power consumption and improved reliability.
- Power Saving Modes - Power consumption in sleep mode is less than 1W.
- Auto Standby - Amplifier goes into Sleep mode after 30 minutes of no input signal.
- 70 V / 100 V Direct Drive - Each channel individually selectable for low-Z or high-Z operation.
- 100 V Direct Drive Capability - Higher voltage allows more speakers per output and reduced wiring costs.
- TLC Protection - Protects amplifier from excessive heat and maintains operation by intelligently applying gain reduction when necessary.
- Advanced Protection Circuits - Amplifier and loads are protected.
- Three Year, No-Fault Transferable Warranty - Your investment is fully protected.
- Complies with Green Edge by Harman - Environmentally friendly practices in design, manufacturing, and packaging.
