D&R Lyra 19" rack I/O unit and core

The Lyra is a fully digital desktop production mixer. Its concept originates from heavy investigations
among end users and distributors looking for a versatile compact small universal desktop mixer.
The core of the Lyra is a sophisticated DSP engine. This processing engine involves the latest
developments in DSP technology by Texas Instruments.
An intense cooperation between T.I. and D&R has resulted in a digital audio mixer offering
tremendous DSP power and a superb sonic quality.
Although the Lyra is a digital console, it is operated with the same comfort as a conventional analog
production mixer.
No fundamental concessions have been made towards reliability, high speed controller-response and
system stability.
Apart from that there is the unique capability to control Lyra's functions over the Internet
