This design has been deprecated. See the much-improved Design 3.


I designed a sound system to meet the following requirements:

  • Designed especially for speech, with tailored signal compression.

  • With complete user manual provided for users who are not audio professionals (see manual PDF below).

  • Engineered to minimize single points of failure with a fully isolated emergency signal path and a uninterruptible (battery backup) power supply.

  • Performs automatic room equalization using pink noise and a target curve.

See the user manual (PDF) for more information.
