Harman Kardon Citation Amp
First Product Using the Axign AX5689 Controller Drops in Europe
|
|
|
The new Harman Kardon Citation Amp has been initially launched in Europe, for now. The new product offers a very interesting set of features, in a compact, Internet-connected Class D design, extending even further the brand's Citation family of connected home audio products, including support for WiSA uncompressed wireless surround technology. And carrying the longstanding tradition of the Harman Kardon Citation designation, the new Class D Citation Amp evolves as a Digital Loop Amplifier controlled by the Axign AX5689 IC and audio converter.
For Harman Kardon to announce a new Citation amplifier also meant making sure the brand would remain true to its spirit of pure, accurate sound quality. The challenge for Harman was to design a Class D product that would make sense within the current Citation family of connected products, but also stand out in its technology implementation. And for that, Harman’s audio amplifier design experts approached Axign, a new company from The Netherlands, founded by former Philips and NXP employees who worked on the pioneering Class-D efforts. Axign was ready to deliver its AX5689 audio amplifier controller chip, which uses a digital control loop with feedback that is able to improve dramatically the fidelity of existing Class D solutions.

This Harman Kardon Citation Amp audio amplifier will be used in many applications where the audio sources will be heavily compressed audio streams. As Axign knows, the results will be as good as the weakest link in the total sound reproduction chain. With the Citation Amp, the audio amplifier is not the weakest link anymore. |
|
Of course, after two years of intense work with Harman, Axign was eager to reveal the results to the world. But the current deteriorating pandemic situation forced Harman to postpone its promotional plans, and Harman Kardon was forced to discreetly share information about the Citation Amp exclusively with channel partners in Europe. Axign saw the first listing of the Citation Amp for sale online in early October, but until now there was no press release or official announcement. The first commercially available product featuring its revolutionary technology is now shipping in a very interesting product, and they weren't able to brag much about it...

This Test Bench edition characterizes the 140FCD 1" compression driver from REDCATT. This is a relatively new OEM pro sound driver manufacturer - a privately held, international company established in 2014 and based in FuMing Industrial City, DongGuan, China. The core management team at REDCATT has been sourcing and building transducer components, sub-assemblies and systems in China for more than 25 years, and its team members have been working around the world for the biggest companies in the audio market with direct R&D and manufacturing experience. The self-stated objective for REDCATT was to create a true state-of-the-art facility, focusing on production quality audio products. And the 140FCD is a truly impressive compression driver. Designed for use with 1" throat horns, the REDCATT 140FCD is definitely in the running for this year’s best-looking driver packaging! It is driven by a 35.5 mm (1.45”) diameter voice coil wound with edge wound copper-clad aluminum wire (CCAW) on a non-conducting Kapton-type former, driving a polyimide composite diaphragm and vented surround.
