Focus 20 XD in the living room

Digital signal processing… and why it’s great

March 01, 2017

We never use DSP to fix mistakes or gloss over flaws. Our engineers have harnessed its power for the forces of good. Here’s how…

Some folk are dead opposed to any kind of processing getting between the signal coming out of their amp and the sound coming out of their speakers. They worry the extra layers of signal path will degrade the information and sully the overall performance.

Our engineers kept that in mind when it came to re-engineering the insides of the 2017 Focus XD range of high-end active hi-fi speakers – which is why they designed it to keep the signal pure all the way from the source to the very last second at the driver itself.

Ever since we introduced the original Focus XD series, we’ve been researching better quality through DSP, acoustics and psycho-acoustics. Part of this process led to the LYD professional studio monitors. And, along the way, we realised that the original Focus XD hardware had the potential for even better performance.

So instead of tweaking the programming, we decided to take a fresh look at the system and re-design the complete signal-processing flow from the ground up. It unlocked the hardware’s full potential, and created a new version of Focus XD with substantial improvements to its performance.

Running the show is cutting-edge technology capable of handling full-fat, 24-bit/192kHz hi-res files. 

All the speakers in the range share common controls and connections – so if you want to mix-and-match between models in the range, you can. There’s digital coaxial in and out, plus analogue input (with adjustable sensitivity), as well as a seven-position control for fine-tuning the speakers’ placement in your room.

And if you add the Dynaudio Connect box, you get digital optical, another digital coaxial and RCA and 3.5mm analogue inputs – plus mini-USB (which can stream 24-bit/96kHz files), aptX Bluetooth and Wi-Fi connectivity (including Spotify Connect and DLNA).

Here’s what we’ve upgraded…

Digital amplifiers and volume

The relationship between the digital amplifiers and the drivers has also been optimised, including the overload-limiters: redesigning the signal flow here has resulted in higher volume levels from the drivers without distortion or compression. It also improves signal-to-noise ratios and dynamics and, in the case of the Focus 60 XD, gives even deeper bass.

Improved position compensation

Less need for complicated crossover filters means there’s more computing horsepower available for speaker-position compensation. That doesn’t mean simply altering the bass – it covers the whole frequency spectrum. The technology adjusts for variances that happen in frequency and phase when placing the speaker near a wall or in a corner. The 2017 Focus XD can now do this at a higher resolution for greater accuracy – and better quality even when speakers can’t be placed optimally in the room.

Brightness control

Also new is the ‘brightness’ control from Dynaudio’s LYD pro-studio range. It adjusts the whole frequency character of the speakers, rather than just the treble. Users can set an overall brighter or darker presentation to suit their room and preferences.
