D&R Lyra Digital Broadcast Console


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. 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.

The core of the Lyra is a sophisticated DSP engine. This processing engine involves the latest developments in DSP technology by Texas Instruments. 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

Over 18 inputs (7x digital, 7x analog, 4x microphones inputs) are connected to a digital cross-point router to accept various formats of audio. This router actually is an integrated programmable patch-bay allowing you to send any of the input signals to any desired processing channels of the DSP’s.

These processing channels consist out of a three band parametric Eq-section and dynamics control application. The signal output by the DSP channel can be routed to main stereo busses. Every main buss is stereo and has dedicated analog outputs, but the bus signals can also be routed to a digital output as well.

The Lyra-4 has four processing channels with 100m faders with large illuminated on and Cue switches and a rotary encoder for multiple functions. A LCD per channel shows input selections and many other functions.
