HARMAN’s Crown Intros DCi Network Display Amplifiers With Front Panel Display and AVB
HARMAN’s Crown Audio is expanding its DriveCore Install (DCi) Series amplifier range with the introduction of its DCi Network Display 8|600ND and 4|1250ND power amplifiers. These amplifiers feature front-panel status displays and AVB (Audio Video Bridging) connectivity. The new eight- and four-channel DCi Network Display amplifiers will actually be the first professional audio amplifier to be certified by the AVnu Alliance.
Both DCi Network Display amplifiers feature a front-panel display and LEDs and a large multifunction knob and push buttons enable instant access to control functions. The amplifiers are compatible with HARMAN’s HiQnet Audio Architect system setup and control software and utilize TCP/IP-based protocol in HiQnet for network monitoring and control.
The eight-channel DCi 8|600ND is spec’d at 600 watts into 8 ohms (300, 600 and 300W into 16, 4 and 2 ohms) and the four-channel DCi 4|1250ND provides 1250W into 8, 4 or 2 ohms (625W into 16 ohms). Both amplifiers offer direct drive “constant voltage” capabilities for 70Vrms and 100Vrms amplification without the need for a step-up transformer, yielding higher audio quality in distributed audio applications with power outputs of 1250W and 600W respectively.
Like all Crown DCi Series amplifiers, the DCi 8|600ND and DCi 4|1250ND utilize HARMAN’s proprietary DriveCore (Class D) amplifier IC chip for efficient operation from a compact form factor measuring just 2 RU high. The DriveCore chip combines the amplifier driver stage into the power output stage along with additional audio-signal functions, yet is about the size of a postage stamp.
Both amplifiers provide a host of networking and control features including continuous load monitoring, error reporting, pilot tone monitoring and programmable general purpose input/output (GPIO) ports. The DCi 8|600ND and DCi 4|1250ND offer extensive DSP capabilities such as LevelMAX limiters for the inputs and outputs, with thermal limiting, input and output delay, input and output EQ, built-in crossovers and a built-in signal generator.
