System structure

4 System structure
The Lyra system is a high-tech digital system, which is based on a 19" 2HE rack. In combination with the
control surface(s) you will get a very easy to use console with many features that can work as a standalone
unit and has a boot time of a couple of seconds (if network is disabled).
The control surface(s) give you direct access to all the parameters you need to control in real time. Like the
Fader level, routing and EQ/Dynamics. All other advanced settings can be done by using the web server or
remote software (ActiveX) by Ethernet.

4.1 19" Rack

The 19" rack is the engine of the Lyra. All audio processing and routing takes place in this unit.
This rack can work without Control Surface or Remote Software. On this 19" rack you can find 4 MIC's, 2
Mono analog and 5 Stereo analog Inputs, 7 Stereo Digital Inputs and Outputs all with sample rate
converters. You have dedicated analog outputs for PROG, SUB, AUX, CRM and PHONES. All interfacing
and connectors are explained in the section Hardware.

4.2 Control Surface

A separate unit with knobs and faders is used to control the Lyra. There are two connections at the 19"
rack to make it possible to have at maximum 8 (stereo) faders. Further this control surface holds a phones
jack which gives the CRM signal!
The Control Surface is a very simple and easy to understand interface to the Lyra engine. You can use the
surface for all basic functionalities such as; Source select, EQ settings, Dynamics Settings, Routing etc.
A separate master section gives the possibility to determine the function of the module encoders and the
CRM source. Of course you can adjust the CRM level and the DIM and Talkback.

4.3 Software (external)

By using the Ethernet connection you have the possibility to control the Lyra from every workplace in your
network. By using a crosslink cable you also can use the Lyra on a stand-alone PC.
The Lyra can receive an IP address via a DHCP server, or you can give a Fixed IP ! When this IP is
known, you are able to connect to the Lyra by software (HTTP web server or ActiveX object). Later we will
give an overview on the options you have with the remote software/web server.
