introduction

​

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

​

The totally software-controlled Lyra secures absolute stability due to the dedicated written DSP software. Via the UTP connector (100 base-TX) you can configure the Lyra with your laptop/PC through a standard Internet web server anywhere on the globe.

Diagnosing is also possible.

equalizer

dynamics section

buss system

The Eq section of the Lyra consists out of a three band full parametric equalizer.

All bands provide a boost/cut of 18 dB max.

A Q-factor between 0.1 and 3 can be set within a frequency range from 10H to 20KHz in the configuration software. This applies for all bands.

The LF-control features a special function.

When attenuating, the LF band functions as a shelving filter. But when amplifying the LF band transforms the shelving function into a bell shaped curve.

This prevents amplification of any unwanted subsonic frequencies.

​

​

The dynamic range control is a highly intelligent compressor. A lot of effort has been spent on creating a user-friendly intelligent yet effective dynamics control algorithm.

One single control sets the amount of compression applied.

The absence of ratio’s and thresholds allow fast and ‘instant-result’ adjustments during on-air situations.

​

​

​

The 4 stereo processing channels are fed to the main busses by means of a digital output router. The four system busses are: Program bus, Sub bus, Aux bus and Clean feed bus. The signal on each bus always appears in analog form on a dedicated output.

​

The audio-paths within the Lyra are programmable due to the presence of an input router.
This eliminates the need for an external patch-bay. The input matrix is situated between the input modules and the DSP.
It allows a custom configuration of the various inputs into the 4 stereo processing channels.

​

​

​

​

Signal processing takes place in one DSP. Processing uses precise floating-point calculations at a word-length of 32 bit.

All audio signals throughout the console preserve their 24 bit resolution from the input conversion. Even 16 bit data streams, like CD-players, have 24 bits reserved.

This way the audio data always preserves the sonic characteristics of the original input signal. Processing includes EQ as  well as dynamics control in all 4 channels.

​

​

The outputs of the Lyra are available in analog and digital form. There are six 9 pin sub-D connectors on the back of the 19”rackunit to provide you with all then outputs. Every main buss has its own dedicated analog output. The Lyra features two main outputs in analog and digital format.

​

The Lyra has a separate control surface that can be controlled up to 10 meters away from the 19”rack mountable in/output interface.

​

The Lyra accepts all standard input formats ranging from microphone signals, analog line, AES/EBU, S/P-DIF coaxial, S/P-DIF optical.

​

The 4 mic inputs are electronically balanced and provided with individual phantom power switches and 4 insertion points.

A convenient aspect of the Lyra is that all Mic connectors are on industry standard XLR type connectors, compact 9 pin Sub-D female connectors, cinch, jacks, as well as the usual digital format type of connectors.

​

On the front panel of the 19” module you can connect your second set of headphones (set one is on the control surface itself).

For easy access we have positioned the analog Cinch in/outputs of input 7 (with level control for the inputs) on the front panel of the 2HE 19”in/output rack. Input 7 is also positioned on the front of the 19” module for easy access.

A digital input (also nr 7) on the front panel of the 19” module gives you S/P-Dif in/outputs.

​

Four electronically balanced mic inputs with switch-able phantom power on XLR’s complete the front panel input access.

There are also 2 mono inputs available for connecting external Hybrids.

three band EQ

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.

Monitoring functions are analog making interfacing with the outside world very simple and easy to understand.

The Lyra-4 has four processing channels with 100m faders with large illuminated On and Cue switches an a rotary encoder for multiple functions.

A LCD per channel shows input selections and many other functions.

In the right hand section of the console are dedicated instant access functions for Source selection, Gain, EQ on/off, Dynamics on/off, Aux, Pan, Program and Sub selection.

The analog master section with 16 segment led bars and source select switches makes interfacing very easy with all sorts of  monitoring devices.

​

A CobraNet option is available for integration within our network solution to share more sources.

​

An Ethernet connector is available for remote control via TCP/IP protocol.

software

The LYRA is completely programmable for nearly every aspect of the in- and output behavior.

remote software

It is also possible to service and/or control the Lyra from a remote location. You can log on to Lyra’s web-server, check settings and its log data and simply access the FTP server to transfer presets and or update firmware. It could not be easier.

You can even control your audio from remote locations by using a TCP/IP connection. The ActiveX control,

(which is part of the package), makes it possible to write your own
programs, like; scheduling, or make scripts (macro’s) to control the Lyra.
