Unveiled by the American manufacturer at the CES show in Las Vegas 2021 last January, the Harman Kardon Radiance 2400 system is a major step in the development of an offer of connected, multiroom and versatile audio products.
Constant Beamwidth Technology
First and foremost, the Harman Kardon Radiance 2400 pack sports a splendid design with two stick-type speakers that are 1.8m high and only 51mm wide and 58mm deep. Each of them has 24 loudspeakers of 1.25 '' (3.18 cm) implemented by the exclusive Constant Beamwidth Technology. The latter aims to offer everyone in the room the same sound experience with the transducers of each speaker radiating in various directions to generate reflections of the waves on the walls and create a surround environment. Likewise, these speakers also benefit from the Digital Loop Amplifier process, still exclusive, intended to correct distortion anomalies linked to digital amplification. For its part, the subwoofer adopts a 25 centimeter membrane. Namely, the total power of the amplification is 450 W (2 x 125 W for the speakers + 200 W for the subwoofer).
Connectivity and connectivity
The Harman Kardon Radiance 2400 has four HDMI 2.0b inputs, HDCP 2.3 certified and HDR10 compatible, plus an ARC output. These connectors bear witness to the philosophy of the Radiance 2400, intended to be associated with the living room diffuser (television, video projector, laser TV, etc.) and by concentrating all audio-video sources. But the Harman Kardon Radiance 2400 system does not deny the audiophile origins of the brand and allows, thanks to an optical input and a 3.5 mm mini-jack to connect, for example, an audio CD player and thus enjoy the best of both worlds: music available on physical media and dematerialized music. Also present, an Ethernet port for those who do not wish to use Wi-Fi.
In addition to connectivity, the connectivity of the Harman Kardon Radiance 2400 is based on Wi-Fi ac, Bluetooth 4.2, AirPlay 2 and Chromecast (integrated) compatibility. These allow access to sound content stored on a mobile device (smartphone, tablet, computer, etc.) or on a NAS hard drive via the Google Home or Apple iOS applications, the supplied Bluetooth remote control, or even through the display. touch screen on the front of the multimedia center.
Wisa wireless technology
As mentioned in the title of this article, the speakers and subwoofer of the Harman Kardon Radiance 2400 system communicate wirelessly with the multimedia center using the Wisa process. Finally, thanks to AirPlay 2 and Chromecast, the multiroom function is standard on the Harman Kardon Radiance 2400 pack, especially with the Harman Kardon Citation speakers.
Last precision, the Harman Kardon Radiance 2400 set is only available at certain resellers, those able to ensure an optimum installation of the equipment with an optimized calibration. Indicative price: 3,990 euros.
