Bricasti Design was founded in 2004 by ex-Harman Specialty Group employees Brian Zolner and Casey Dowdell. Brian started at the original Lexicon in 1984 and held various positions in sales, developed its international sales network for both professional and consumer markets for the Lexicon brand, and before leaving was VP of worldwide sales. Casey later joined Lexicon as a DSP software engineer, and his primary focus was algorithm development for professional and consumer products including work on high end reverberation, Logic 7, and later Mark Levinson products when development for that brand became part of the group in MA with the closure of Madrigal.
The M1 digital to analog converter is a dual mono design; there are two completely isolated channels, each with its own dedicated linear power supply, D/A converter, DDS clocking, and analog circuitry. This design ensures that analog crosstalk is virtually nonexistent, that the necessary power requirements for each channel are well met and isolated from each other and the digital processing is isolated, having its own power supply. With our twin DAC design, the dynamic range for each channel is optimized by using the stereo ADI 1955 D/A converter in a mono configuration. The M1 also includes Bricasti's own proprietary filter technology, further opening new territory with what is achievable in a modern D/A reference.
- Trigger In - for triggering the M28 into standby mode from an external device like a preamp or other external remote control.
- RS422 Port - currently only used for system diagnostic monitoring and has no use for the user.
- Trim Control - input trim control can be used to lower the input sensitivity of the M28 to better match the outputs of a preamp or more importantly the outputs of the M1 DAC when using it to drive the M28 directly with no preamp. This attenuator is set by a logic controlled relay switch and is adjustable in 6 dB steps. In practice this means the most dynamic recordings will have the M1 doing a few db of gain reduction in the digital domain.
