D&R Lyra 8 fader control surface

D&R Lyra 8 fader control surface

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
