Cardia DSP is in some ways the heart of the 3SB audio platform. Consisting of a dedicated, high powered CPU, and a multi-channel digital to analogue converter, the Cardia DSP provides everything required to “run” the Keystone and Bedrock Systems, with the Ochto amplifiers.
Cardia DSP provides:
- Driver linearisation, where each driver is measured and linearised to perform optimally
- Driver timing alignment, so that music arrives coherently to the listener
- Active cross-overs, involving 7 drivers for each Keystone, and 8 drivers per Bedrock – for a total of up to 30 drivers (in a Bedrock System)
- 32 channel DAC running at 192KHz
- Option for ADC at 192KHz with additional module, supporting line level and phono input
- Integration with Roon for volume and mute
- Digital 64bit volume control with support for equal loudness contouring
- Support for user supplied Digital Room Correction FIR’s to be included in DSP
- Management via Web UI
Cardia DSP consists of the following:
- 32 chanel DAC
- CPU board/computer for DSP
