Frequently asked questions
We provide three methods of remote volume control: Managed via Roon (if you’re playing music from a library or streaming service) Mobile web app via Wifi IR remote Both ways use volume control built into Cardia DSP, based on 64 bit audio. Other configuration is also available via the web Read more…
Cardia DSP is based on AVB, a digital audio over IP standard for managing audio streams via ethernet networks. To add any analogue device (e.g. turntable) we therefore need to digitise and put the digitised audio stream onto the network, where it is routed to Cardia DSP and onwards to Read more…
We’ve integrated Cardia DSP with Roon, so that you are able to control volume and mute of Keystone and Bedrock systems from within Roon. This is via the Roon CDSP Extension (available here: https://github.com/siraaris/roon-extension-cdsp).
We’ve implemented a basic power reduction process via DSP for the low frequencies that will help protect the woofers on the Keystone and Bedrock Speakers. But we also recommend that common sense prevails, as not all music is recorded/presented at the same level, and it’s impossible for us to cover Read more…
We recognise that some listeners will have existing amplifiers, or wish to employ different types of amplifiers. All of our products are designed modularly so that alternatives can be employed. For example, it’s possible to utilise (say) a different 4-channel amplifier for the Tweeter, Midrange and Midwoofer. Just let us Read more…
We provide a 3 year warranty. Our products are designed to be user supportable. Should something go wrong and need attention, you should be able to return the component (e.g. specific driver) to use, rather than the whole speaker enclosure.
The simplest configuration is the Keystone System, which can be upgrade with Bedrocks later.
Cardia DSP consists of a dedicated multichannel DAC and computer that is able to drive 2 x Keystone and 2 x Bedrock speakers. Our configuration is 192KHz sampling rate.
Our Ochto Amplifier provides 8 channels at 250W per channel. They connect to Cardia DSP and either Keystone or Bedrock speaker. Internally there are 4 very quiet micro fans that provide cooling where needed, controlled by a dedicated Raspberry Pi 4.
