The Keystone and Bedrock Systems are comprised of 5 key components:
Primary Speaker – a pair of Keystone Speakers. Each Keystone has 4 subwoofers in a custom DSP cardioid configuration.
Subwoofers – a pair of Bedrock Sub Arrays. Each Bedrock has 8 subwoofers in a custom DSP cardioid configuration.
Power Amplifiers – Each Keystone or Bedrock Speaker requires a dedicated Ochto Amplifier, which are based on Hypex NC252MP power amplifier modules. Each Ochto amplifier includes 4 x Hypex NC252MP modules, providing 8 channels 250W.
DSP CPU – we currently support a customised macOS Monterey running on an Apple M1 mini. Support for Linux on Intel is currently in development.
DAC – we currently support the RME M-32 Pro DAC. Support for MOTU AVB multichannel DAC such as the 24Ao is currently in development.
ADC – we currently support the RME AVB Tool. Support for MOTU ADC (analogue to digital converter) is in development.
