PRODUCT SAFETY
This product is manufactured with the highest standards and is double-checked in our quality control department for reliability in the "HIGH VOLTAGE" section.
CAUTION
Never remove any panels, or open this equipment. No user service-able parts inside. Equipment power supply must be grounded at all times. Only use this product as described, in user manual or brochure. Do not operate this equipment in high humidity or expose it to water or other liquids. Check the AC power supply cable to assure secure contact. Have your equipment checked yearly by a qualified dealer service center. Hazardous electrical shock can be avoided by carefully following the above rules.
EXTRA CAUTION FOR LIVE MIC RECORDING
Ground all equipment using the ground pin in the AC power supply cable. Never remove this pin. Ground loops should be eliminated only by use of isolation transformers for all inputs and outputs (optional). Replace any blown fuse with the same type and rating only after equipment has been disconnected from AC power. If problem persists, return equipment to a qualified service technician.
PLEASE READ THE FOLLOWING INFORMATION
Especially in sound equipment the following information is essential to know. An electrical shock is caused by voltage and current, actually it is the current that causes the shock. In practice the higher the voltage the higher the current will be and the higher the shock. But there is another thing to consider and it is resistance. When the resistance in Ohms is high between two poles, the current will be low and vice versa. All three of these; voltage, current and resistance are important in determining the effect of an electrical shock.
However, the severity of a shock is primarily determined by the amount of current flowing through a person.
A person can feel a shock because the muscles in a body respond to electrical current and because the heart is also a muscle it can be affected when the current is high enough. Current can also cause the chest muscles to contract, which affects your breathing. At what level is current dangerous? Well the first feeling of current is a tingle at 0.001 Amp of current. The current between 0.1 Amp and 0.2 Amp is fatal.
Imagine that your home fuses of 20 Amp can handle 200 times more current than is necessary to kill. How does resistance affect the shock a person feels. A typical resistance between one hand to the other in "dry" condition could well over 100,000 Ohm.
Always earth all your equipment by the grounding pin in your main plug. Proper wiring and isolation input/output transformers (optional) should only cure Hum loops.
PRODUCT SAFETY
Replace fuses always with the same type and rating after the equipment has been turned off and unplugged. If the fuse blows again you have an equipment failure, do not use it again and return it to your dealer for repair.
And last but not least be careful not to touch a person being shocked as you, yourself could also be shocked. Once removed from the shock, have someone send for medical help immediately
Always keep the above-mentioned information
in mind when using electrically powered
equipment.

1 Introduction
This manual will give you a detailed explanation of the functionality of the Lyra and all its features. It is advised to read this manual once before touching any control, or even thinking about hooking up the system. We know that that is actually the firsts thing you want to do but please do NOT and discipline yourself to read the manual first. The manual gives all sorts of valuable information before getting started and it saves you from getting in touch with us for all sorts of questions. You can use this manual later on as a reference.
In the first chapters we shall give you an overview of the Lyra and its features. In this way you can have an impression of how to implement the system in your application.
The next chapters will deal with interconnecting the various parts of the system and its external interfacing with your equipment
When the Lyra is installed and wired, you can finalize its interfacing with the instruction in the following chapters.
After having installed the Lyra you will have a very complete mixer with a human interface that is very logical and understandable by intuition.

1x Crosslink network cable
1x CD-rom
This manual
3 Start working with the Lyra
The internal power-supply is auto-sensing for the range of [85-264V/47-63Hz]. If the power coming from your wall-outlet is not according these specs, do NOT connect the Lyra.
Take the fader module and the 19”Rack unit out of the box.
Hook up the 15p sub-D cable between the fader module to the 19” rack unit (“TO CNTRL UNIT 1”)
You can now also hook up the UTP cable to your ETHERNET 802.3 network if you would like to make settings. In chapter 10.5 you can find how to setup the Lyra for networking.
Connect the power supply cable to the 19" rack and to the wall outlet.
Turn on the power.
After 3 seconds you must have control over the DSP engine. You can hit ON/CUE buttons to check functionality. Further there are enhanced functions in the Master Section, one example:
Hit the button SRC (Source selection for this module). You can turn the encoder at the channel to make your selection. Pushing the encoder means the default setting. The functions Prog and Sub don’t have a rotating function… they only respond to the pushdown action!
System structure
Lyra Digital Mixer from D&R Phone +31 294 418014, email: info@d-r.nl
Page 9
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.

5.1 Input matrix
To give you the flexibility you need in your applications the Lyra has a full matrix before processing takes place. You can assign one of your inputs to the eight modules in any way you want. Furthermore you can bring one of the inputs to the external inputs to make them available at the CRM buss.
5.2 Buss structure
As mentioned before, every module features EQ- and dynamic processing. This is why these channels are often referred to as ‘processing’ channels. The output of the 8 stereo audio processing channels can be routed to different busses. Busses that are available are:
Stereo program buss.
Stereo sub buss.
Stereo aux. buss.
Stereo CUE buss.
Automatic Mono Cleanfeed 1
Automatic Mono Cleanfeed 2
The 6 CRM sources (Prog, Sub, Aux, CUE, Extern 1, Extern 2) may be summed into the CRM buss.

5.3 Outputs
For the Prog, Sub, Aux, Cleanfeed 1, Cleanfeed 2 and CRM busses, there are dedicated analog outputs. For all Digital outputs you have a separate router which makes it possible for you too choose which buss is connected to the digital output. Due to the advanced routing matrix you also have the option to route any input directly to an output.
Analog/Digital levels with the Lyra

6 Analog/Digital levels with the Lyra
Before you can start working with a (digital) console you need to understand all level standardization for the inputs and outputs. In the Analog domain it is sometimes confusing. But now we have to deal with even more formats. Often we use the following parameters:
0 dBu Analog level of 0.775V at 600Ohm. 0 dBFS FS= Full Scale (means maximum digital value, higher=clip).
Table 1: Level Definitions
First we will give a simple example with a CD-player:
Your home CD player plays CDs, which are most of the time ‘normalized’. In the mastering process the highest peak value is monitored and is set as the 0 dBFS reference. Like in most common players they use a standard where the maximum output voltage is 2Vrms, which means around +8 dBu.
An example in an analog system.
The analog-mixing console must have enough headroom to handle your audio without clipping. An often-used standard of 20dB headroom is enough for most circumstances.
Those two examples show exactly the problem of combining the digital and analog world. We would like to have headroom in our mixer because we are adding signals, but we don’t want too much headroom because we ‘eat bits’ (20 dB headroom is more than 3 bits).
The Lyra supports both AES (and Dolby) and EBU standards for the digital outputs. That means you can choose how much headroom you want on the digital output. 0 dB on the meter is equivalent to:
- 20dBFS on the digital output (AES)
- 9dBFS on the digital output (EBU)
To achieve this you have two different headroom settings for the digital outputs. One headroom setting is fixed 20dBFS. The other is adjustable from 0 to 20dBFS headroom adjustable in increments of 1dBFS. The default setting is 9dBFS.
This means you have on your digital outputs enough headroom! The 0 dB level on the meter is +6 dBu on the balanced analog outputs. Because you also need your bit-resolution we interface with 24 bits and process the signal with 32 bits floating point! This provides you with sufficient headroom.
For ease of use the console is also equipped with cinch inputs and outputs. It’s difficult to specify a standard for this type of connector. This is because many different manufacturers use different values. When the console leaves the factory the cinch outputs are trimmed to 0 dBu if the level on the meter is 0 dB. That means if you connect a digital recorder with a maximum input of 2Vrms (for example a calibrated input) you still have 8 dB of headroom. Of course you will also find a ‘Record level’ on the most recording equipment.
Even if we understand the current situation with the levels we still have to overcome some problems. If we connect signals and the level seems not to be correct we can easily adjust the gain on the control surface. This can instantly correct the problem. But for digital inputs the level problem is more related to the medium. CD-players and MD-players are most of the time playing a medium, which is normalized. That means if we should connect it directly to the console, we see an incoming signal of +20 dB !!! Therefore you may set-up a ‘headroom trim’ for each digital input via the web server. If you connect a CD player to digital input 1 you can already set the headroom trim to -20 dB in the Global Settings dialog on the webpage. See also section 11.5. The Lyra will then make a level correction for this medium (if assigned to a module/processing channel).
Now you know how you can interface between the analog and digital world with the understanding of what is happening with your levels. We hope this chapter gave an insight on this matter.
Analog/Digital levels with the Lyra

Page 13
To summarize things shortly:
0 dB on your meter is:
• +6 dBu on the balanced input/outputs
• 0 dBu on the unbalanced inputs/outputs
–20 dBFS fixed or -20 dBFS to 0 dBFS variable at the digital inputs/outputs.
Network Basics

7 Network Basics
This chapter gives you a short overview on the network basics. This chapter is meant to give you some information about networking. When reading this chapter it's more easy to understand the technical backgrounds of the network possibilities. In general we can divide the network possibilities of the Lyra in two types. WAN – Wide Area Network LAN – Local Area Network
The first, WAN, is mostly based in TCP/IP (also known from the internet). The second, LAN, is in our application 10/100 Mbit Ethernet based.
7.1 Network Layers
In the network theory they often make use of layers to create a visualisation of a network connection. This is called the OSI model (Open System Interconnect). It will be too much information at this point to explain the complete OSI model. Below you will get some basic information regarding layers.
Figure 2: OSI Model
Physical & Data Link Layer = Ethernet Network Layer = Internet Protocol or Cobranet Transport Layer = TCP or Cobranet
In higher layers we will find protocols like HTTP, FTP, SNMP etc….
Actually we are now looking at the protocol stack which contains the Ethernet protocol. TCP/IP protocol, HTTP, FTP, Cobranet etc…
7.2 The Layer Implementation
For the Lyra, we always use the Ethernet protocol for the Data Link & Physical layer. You can imagine this Ethernet protocol as an envelope. The information on the envelope is Source Address or Destination Address. The information inside this envelope represents the next layer. In this layer you can find TCP/IP data from the Lyra or Cobranet data from the Lyra.
Figure 3: Network Implementation
Network Basics
Lyra Digital Mixer from D&R Phone +31 294 418014, email: info@d-r.nl Page 15
TCP/IP is a protocol that is well known in WAN structures. This means there are many Data Link & Physical Layers that can carry TCP/IP. In WAN structures the Cobranet protocol is not known, so that will only function on the Ethernet based networks.
What happens if a destination of a TCP/IP envelope is outside the Ethernet network? The TCP/IP envelope will be redirected to the ‘gateway’. This gateway takes the TCP/IP packet out of the Ethernet envelope and repacks the TCP/IP envelope in a new envelope for the new protocol (for example DSL or ISDN) This explains how it's possible to have TCP/IP data over WANs and Cobranet only over LANs.
7.3 TCP/IP Network Addressing
The TCP/IP protocol is a higher-level networking protocol and has its own system of addresses called IP addresses. TCP/IP, like other network protocols, has its own addressing scheme and data structure. Thus, contained within the Ethernet payload is another series of fields containing IP source and destination address information, as well as another payload containing TCP data. This “nesting” within the Ethernet payload continues until the protocol(s) being transported is completely defined. The most important thing to understand is that the networking protocol in use is completely independent of Ethernet. Ethernet is simply the delivery system, and it doesn’t know or care about the networking data that it’s carrying in its payload. This enables Ethernet to carry many different networking protocols on the same network. It is left up to the networking software running on the receiving system to understand the networking protocol information extracted from the Ethernet payload field.
7.3.1 IP Address
An IP address is a unique identifier for a device on a TCP/IP network. Within an isolated network, it is possible to assign IP addresses at random as long as each address is unique. However, connecting a private network directly to the Internet requires using registered IP addresses (called Internet addresses) to avoid duplicates. An IP address is a 32-bit numeric address (four sections of 8 bits each) written in “dotted decimal notation”. The number in each section can range from 0 to 255. The address consists of 2 parts, the network number (or as it is more commonly referred to today, the network prefix) and the host address. The host address is the unique address of the network node, while the network number identifies the network on which the host resides. Each host on a network shares the same network number but must have a unique host address. Likewise, any two hosts can share the same host address as long as they have different network numbers. The InterNIC Registration Service originally assigned Internet addresses from three classes, where each class fixes the boundary between the network number and the host address at a different point within the 32-bit address. This is known as “classful” addressing.
Class A - 16 million hosts on each of 127 networks (1.xxx.xxx.xxx - 126.xxx.xxx.xxx) Class B - 65,000 hosts on each of 16,000 networks (128.0.xxx.xxx - 191.255.xxx.xxx) Class C - 254 hosts on each of 2 million networks (192.0.0.xxx - 223.255.255.xxx)
Unfortunately, no one expected the Internet to grow as quickly as it did, and the limitations and inflexibility of this method of addressing were unforeseen. Adding another level to the address hierarchy, the subnet, helped to temporarily overcome many of these shortcomings.
Network Basics
Lyra Digital Mixer from D&R Phone +31 294 418014, email: info@d-r.nl Page 16
7.3.2 Subnets and Subnet Masks
A subnet is a part of a network that shares the same prefix. It enables a network administrator to further divide the host part of the address. Previously, another network number had to be requested from the Internet before a new network could be installed at a site. W hen a network is divided into subnets, a part of the host address is used to identify a particular subnet. Let’s look at an example:
The network number is:
192.168.0 –or- 11000000.10101000.00000000 in binary
and the host address is: 2 –or- 00000010 in binary
If the network needs to be divided into 13 subnets, the first 4 bits of the host address (0000) would be reserved for identifying the subnet. This would allow for a total of 16 possible subnets, as subnets can only be created in blocks of powers of two. The first 4 bits of our host address could then be changed to indicate the subnet number:
nnnn0010
Once the network is divided into subnets, the IP nodes must be told where the division between the extended network number and the host address occurs. This is done using a subnet mask. The subnet mask is the network number plus the bits reserved for identifying the subnet. To come up with a subnet mask, the bits for the network number, including the new subnet number, are all set to 1. In our example the subnet mask would be:
11111111.11111111.11111111.11110000 –or- 255.255.255.240.
7.3.3 Configuring the switch
Switch configuration is usually only necessary if you are using managed switches in your design. In most cases, using the factory defaults will be sufficient, and only an IP address and subnet mask needs to be assigned.
7.3.4 Test Connectivity
Probably the quickest and easiest way to determine that all the devices are connected to the network is to ping the devices. Ping is a utility that is used to determine whether or not a specific IP address is accessible, which makes it very handy for troubleshooting network connections. When the ping command is issued, an ICMP (Internet Control Message Protocol) packet is sent to the specified address and a reply is expected. If a reply is received, this indicates that the remote device is reachable over the network. If no reply is received, this indicates a problem with communication over the network. To issue a ping command, open the Command Prompt, and type:
ping xxx.xxx.xxx.xxx
where: xxx.xxx.xxx.xxx is IP address of the device you wish to contact

7.3.5 DHCP
DHCP stands for: “Dynamic Host Configuration Protocol”.
DHCP is a TCP/IP service that you can use to set network clients' TCP/IP configurations automatically as they attach to the network. This configuration is done by providing the DHCP server with one or more scopes. A scope is nothing more than a range of IP addresses that may be assigned to clients on a temporary basis. The length of time that a client is allowed to use an IP address from a DHCP server is called the client's lease period. As you can see, DHCP eliminates the need to manually configure each client; it also helps to prevent duplicate IP addresses and can help to conserve IP addresses when they're in short supply. However, for DHCP to function correctly and efficiently on large networks, proper planning is essential. If it is set up improperly, DHCP can cause headaches.
As I mentioned earlier, DHCP automatically configures clients for TCP/IP at the time the clients attach to the network. Obviously, this process doesn't happen by magic. Getting DHCP to configure a client for use on a network requires several messages to be passed back and forth across the network. Although these messages tend to be small, if many clients are attempting to get an IP address at the same time, the excessive traffic created can slow down the network. One way of dealing with this problem is to limit each DHCP server to servicing only one specific subnet. By doing so, you'll isolate each subnet's DHCP-related traffic and prevent it from flowing onto the rest of the network.
If you want to use static IP addresses on your servers, but you like the idea of using DHCP for consistency, you can use a reservation system to ensure that a client receives the same IP address each time it connects.
Cobranet Basics
Lyra Digital Mixer from D&R Phone +31 294 418014, email: info@d-r.nl Page 18
8 Cobranet Basics
This chapter gives you information for working with Cobranet. It's just a basic explanation of audio networking with Cobranet. For more information you can view the website http://www.peakaudio.com
.
8.1 Cobranet Device
A Cobranet Device has two RJ45 connectors which you can hook up to a switch or connect with a crosswire to another Cobranet Device. The reason for two RJ45 connectors is redundancy. It will function without problems if you connect just one RJ45 connector.
Internally a Cobranet Device has 4 receive sockets and 4 transmit sockets. Every socket is able to transfer a maximum of 8 mono channels. That means If we have all sockets fully loaded we can send 32 mono channels and receive 32 mono channels.
A receive socket can have only one transmit socket to which it is connected. A transmit socket can have one receive socket and in special cases (multi cast) more receive sockets.
In short it means one Cobranet device can transmit data to 4 different devices, and receive data from 4 different devices.
8.2 Cobranet Bundles
To setup a connection you have to give a transmit and receive socket a bundle number. If a receive socket and transmit socket have the same bundle number, audio is transmitted from the transmit socket to the receive socket.
A bundle number is a kind of identification of the link. Normally the bundle numbers starts from 256 and ends at 65535.
Bundle number 0 until 255 are reserved.
8.3 Cobranet and Ethernet
All Cobranet data is transferred within standard Ethernet packages. This makes it possible to interfere with normal Ethernet data as well as to use standard Ethernet equipment. (For full capacity its recommended to separate Cobranet and data networks)
The topology of the Cobranet network is like your standard computer network. A star network where all devices hook up to a switch.
Figure 4: Star Network
If you interconnect multiple star networks you will get a tree-topology.
Peak Audio has tested a lot of Ethernet equipment, and is maintaining a list of recommended switches. You can find the recommendations at their website: http://www.peakaudio.com

9 Hardware Connections
This chapter will describe all connections to the 19” rack unit in detail. After this chapter you have all information to implement the system within your hardware. Some connections are software dependent and can be configured by software. Chapter 11 will explain everything on this settings. The Lyra is equipped with Sub-D connectors. This way it is possible to have a lot of I/O in a small space. The pinning is as follows for the female Sub-D connectors:
Figure 5: 9 pins female Sub-d
Each section of this chapter has a table which shows how the connectors are wired.
9.1 Analog In-/Outputs
On the Lyra 19” rack you can find several different types of analog inputs. Below we will describe every input type to give you an overview on the dedicated purpose of this input.
9.1.1 MIC inputs
Figure 6: Microphone inputs at front
You can see on the right side of the front panel the XLR connection for the microphones. Here you also have the dedicated phantom power switches providing the MIC inputs with +48V phantom power.
Note: For maximum safety it's best to connect/disconnect the microphone(s) when the console is powered off. This is also required for all the other in/outputs; Make sure you ALWAYS switch off the phantom power before patching the microphones.

9.1.2 LINE inputs
The Lyra can connect 7 analog line inputs. The Input numbers 1-4 and 7 (front side) are stereo inputs. Input 5 and 6 are MONO inputs, with on the same connector a cleanfeed output, so these inputs can be used for a telephone-hybrid.
You can hook up a telephone-hybrid to both MONO inputs. When one of the MONO inputs is routed to a module and the module is routed to the PROG, SUB or both, the cleanfeed function will be activated automatically. When activated all of the signals on the PROG, SUB or both will be added to the cleanfeed 1 (mono input 5) or 2 (mono input 6) buss except for the input signal.
Below you see a picture of the rear view. Here you see all 9Pin SUBD connectors which you can use for the analog inputs.

Table 4: Pinning for Stereo Input 1..4 and Mono Input 5..6
The GPI line on the MONO connectors can be used to connect the RING from your telephone-hybrid. Usually the 'Ring' signal comes from a REMOTE on your Hybrid. Consult your telephone-hybrid manual for information about how to connect the RING to the GPI of the MONO input.
GPO-A and GPO-B make connection if the GPO is activated! Maximum current: 200 mA Maximum resistance when connection made: 12 Ohm Maximum Voltage: 24 V
At the front side of the 19” rack you can find one additional stereo analog input. Below you can see a picture of this section. You have the ability to adjust the input level with the potentiometer located at the left side.

9.1.3 External inputs
The Lyra can sum two external inputs to the CRM buss. The sources for the external busses can be selected by using the web server.
9.1.4 Program/Sub/Aux/CRM outputs
The Lyra is a very intuitive mixer which is very similar to analog mixing consoles. Therefore you also have all common outputs in the analog domain. That means you can directly hook up your equipment. Below you see a picture of the connections available.

9.1.5 Phones outputs
For easy and versatile monitoring there are two headphones outputs implemented on the Lyra. On the control surface the phones is directly connected to the CRM buss. On the surface itself you have a level control for the phones. Below you see the phones connector, which is located at the front side of the 19” rack. This phones connection can be used for example as a studio phones output. With the remote software you can select the source for the studio phones.

9.3.5 Ethernet
The Ethernet connection of the Lyra enables you to connect the device to your local network or directly to your PC.
Note:
When connecting directly to the PC you will need a Crosslink cable. (One crosslink cable
comes with the Lyra).
By entering the IP address of the Lyra in the internet explorer you will receive the Lyra webpage onto your screen. Through the webpage you can make all kind of settings and view all kinds of log-files. Further you can use the ActiveX application to control the Lyra from remote locations!

Table 8: Pinning Control Surface connector
The power-supply for the control surface comes through the 15 pin cable. It's very important to never extend the cable any further than the maximum specified length of 5m. This is also the length of the cable delivered with the package. If the voltage drop on the +5 volt lines becomes to large the control-surface won't function properly.

9.3.7 Cobranet (optional)
CobraNet operates on a switched Ethernet network or on a dedicated Ethernet repeater network (the last is not recommended). CobraNet provides the possibility to send and receive real-time digital audio data over an Ethernet network.
The CobraNet interface has provisions for carrying and utilizing control and monitoring data such as Simple Network Management Protocol (SNMP) through the same network connection as the audio. This makes it compatible to different manufactures so they can also hook up and control information of the Lyra Cobranet side.
CobraNet is Ethernet based, in most cases, data communications and CobraNet applications can coexist on the same physical network (depends on the required audio bandwidth).
The Cobranet module is optional. W hen the module is present then the Lyra will auto-detect it. Automatically the webpage will be updated with the proper menus for Cobranet.

10 Using the Control Surface
Figure 21: The 4-fader Control Surface of the Lyra
It is possible to process 8 stereo channels in parallel. Every processing channel handles source selection, mono, EQ, dynamics, level and routing selection. Now we shall give you a global overview of the Lyra. All hands on features described here can be found on the control surface of the system.
Next to the 4-fader version of the Control Surface there is also an 8-fader version available. This version is a combination of 2 4-fader units. Figure 22 displays the 8-fader Control Surface.

10.1 Input routing
The input signal can be processed as soon as it is converted into the digital domain by specifying an input source for the module. Selecting the source button on the control surface can do this. Now you can use the encoders to select/scroll through the inputs for a module.
After pressing the gain button you can use the encoders to adjust the input level from -20dB to +20dB. The MIC inputs have a gain range of 0dB to +60dB. When pushing the encoder the level returns automatically to the default 0dB (and 30 dB for MIC).
To make a channel mono you must select the mono button and with each press of an encoder you can switch mono ON or OFF.
When pressing the panning button you can adjust the balance level of the signal by turning the encoders. By pushing the encoder the balance returns to center level.
10.2 EQ
Each module of the Lyra has a three-band equalizer. You can select the buttons LF, MF and HF to adjust the gain for each band. With the EQ On button you can activate the EQ on a module. The default frequencies for the EQ bands are: LF = 120Hz MF = 1200Hz HF = 12kHz
The default bandwidth is 2 octaves. To adjust the EQ for your own specific purposes you can use an EQ Tool located on the delivered CDROM. For explanation see chapter 13.
The range for each band is adjustable from -18dB to +18dB maximum. (Depending on the ‘EQ Range’ settings on the webpage.) When pushing the encoder the level returns to a default 0dB. To activate the EQ select the EQ button and press the encoder above the module. If the EQ on the module is ON, one or more EQ-bands are active, the EQ led on the module will be lit.
10.3 Dynamic range control
Every module has a dynamics controller, which enables you to control the dynamic range of the present audio signal. Actually it is a very intelligent, automatic compressor/limiter. The amount of dynamic compression is set by just one control. This allows you to make “on the fly” adjustments without having to worry about ratio’s, Attack and thresholds. A reduction in dynamic range is exactly what you get. You can adjust the dynamic by pressing the Dyn button and turning the encoder on a module. In turning the encoder clockwise more dynamic control takes place. The range for dynamics is 0% to 100%. Mind that the amount of effective gain reduction is related to the level of the input signal. As soon as dynamics is set a Dyn LED will be activated on the module. When pushing the encoder the dynamic control returns to its non-effective position, as if it was fully anti­clockwise.
Using the Control Surface
Lyra Digital Mixer from D&R Phone +31 294 418014, email: info@d-r.nl Page 32
10.4 Buss Routing
When the signal has been processed in EQ, dynamics range and level, it can be routed to one or more busses such as the Aux. buss, Program buss, Sub buss and the stereo CUE buss. A description of the individual busses is written below.
10.4.1 Program/Sub buss
The Lyra has a stereo Program and Sub buss implemented. To route a channel to the Prog or Sub buss, you can select the Prog or the Sub button and push the encoder on a module. The Prog or Sub LED will be activated on that module. The signal fed to the Program and Sub buss is always post fader and post ON-switch.
10.4.2 Aux. buss
The Lyra has a stereo AUX buss. This buss accepts signals from the input module post ON-switch and pre or post fader, depending upon your selection on the webpage. The level of the AUX buss can be set by selecting the Aux button and rotate the encoder on a module. the level can be set from -140dB to +10dB. When the Aux level control is above
-140dB the Aux LED on the module will be activated. When pressing the encoder the Aux level will jump to 0dB. Pressing it another time will make the level jump back to -140dB.
10.4.3 CUE buss
The stereo CUE buss can be fed from one or more modules by ways of the CUE switches on the console or on the computer screen. The signal from the processing channel to the CUE buss is routed pre-fader and pre ON-switch. An alternative function of the CUE buss is to use it as a talkback communication switch. This will be explained later on in the manual.
10.4.4 Fader
The Fader is used to set the level of the module before it is fed to the Prog, Sub and other busses.
10.4.5 CRM
You can route multiple busses to the CRM buss. Default the CRM selection is set to 'Interlock'. This means that you can only route one buss at the time to the CRM buss. The 'Interlock' option can be disabled on the webpage. You can read this in chapter 11.5.
The CRM pot on the control-surface controls the volume of the dedicated CRM output on the 19" rack. The DIM button dims the level of the dedicated CRM output from 0 to 144dB depending on what is set on the webpage.
When pressing the talkback-switch the chosen input for talkback is routed to all the outputs who have Conference Talkback enabled.
The phones of the control-surface is fixed routed from the CRM buss. The phones pot controls the volume of the phones output of the control-surface.
Using the Control Surface
Lyra Digital Mixer from D&R Phone +31 294 418014, email: info@d-r.nl Page 33
10.5 Network settings through the Control Surface
The Lyra is a stand-alone mixer. That means that there is no need for a PC during operation. But before you start using the Lyra you may want to make some settings regarding output routing or GPIO usage.
You can connect your Lyra directly to your PC by a cross-link cable or connect your Lyra to your local network (Straight CAT5 UTP cable) and use a PC on the network to connect to the Lyra.
10.5.1 Assigning an IP-address to the Lyra
To enter the special menu on the control-surface you should press all encoder of control-surface1 simultaneously. By constantly repeating this, you will see the following lines in the display of the control surface.
- IP Address
- Subnet Mask
- Gateway Address
- Name Server Address
By default the network-settings are disabled. The IP-address is set to 255.255.255.255.
Note: Whenever you set these addresses you must reboot the console for changes to take effect.
When you have connected the Lyra directly to a PC you must manually assign all four addresses. for example;
Lyra Settings IP Address; 192.168.1.11 Subnet Mask; 255.255.255.0 Gateway Address; 0.0.0.0 Name Server Address; 0.0.0.0
PC Settings IP-Address of the PC; 192.168.1.10 Subnet Mask; 255.255.255.0 Gateway Address; 0.0.0.0 Name Server Address; 0.0.0.0
Note: The IP-address of the PC and of the Lyra must not be the same.
When you have connected the Lyra to a network you have 2 options for setting the addresses. The Lyra can auto-detect the DHCP server, which assigns the network-settings automatically, or you can manually set the addresses. To let the Lyra auto-detect the DHCP server, change the IP address to 0.0.0.0. Now reboot the console and the Lyra will automatically search the network for the DHCP server. When found the Lyra displays the assigned IP address, which you can use to connect to it by webpage.

11 Webpage
The control surface of the Lyra covers all the basic routing and signal processing per channel. To control all the features of the Lyra we need software tools. The software part of the Lyra is a dynamic webpage that is inside the 'brain' of the console. By using it inside a network or on a stand-alone PC you can make all kinds of advanced settings to control and setup the Lyra. In this chapter we will discuss all of the features found on the webpage.
Note: For best viewing results for the webpage use a screen resolution from 1024x768 up to 1280x1024.
11.1 Opening screen
To log on to the webpage you should enter the IP address in your internet explorer. You will get a logon screen. The first time you logon you don't have to enter a username or password. When asked for just press enter. It's best to make a System Administrator account as soon as possible to secure the Lyra. Later on you can define your own users. How to do this will be discussed is chapter 11.10.1 After the logon procedure you will see the next screen.

11.10 Security Settings
The security setting of the Lyra gives users the option to secure the Lyra against misuse of any kind. It's possible to create a database of multiple users who have all kind of different access-levels to the Lyra. Users names can be stored on personal chip-cards. The chip-cards can be used to allow access to the control-surfaces. The chip-cards are fully compatible with the other D&R products like the Sirius and the Scorpius. All these settings can be made in the Security Settings menu.
Figure 35: Security Settings
11.10.1 Users and Levels
Figure 36: User and Level Settings
The User and Level menu gives the user the option create or alter user accounts for the Lyra. In the 'change settings' menu you can adjust the name and the security level of the user. You can also assign a password to the user.
Note:
The password is case sensitive.
Webpage
Lyra Digital Mixer from D&R Phone +31 294 418014, email: info@d-r.nl Page 49
Each user has the ability to store his personal settings made on the control-surface and in the Global Settings menu. The 'Store' button stores your personal settings inside the Lyra. 'Recall' loads your personal setting for you. Each user has an extra checkbox called 'Preset by Chip-card'. When this option is set you preset will automatically be loaded as soon as you insert your chip-card in the control-surface.
Note:
When removing a chip-card, the user will change but the loaded settings will stay!
The following setting are stored in a user-preset; Module 1..8: - Source

Figure 37: User Settings
To delete a user simply empty the username and the password field and change the level back to operator.
There are 6 different user-levels in the Lyra.
System Administrator
This level is the absolute highest you can assign to a user. This level
has fixed privileges and can't be limited.
Supervisor
This is a user definable level.
Operator 1
This is a user definable level.
Operator 2
This is a user definable level.
Unknown
Unknown user is basically the same as Idle user but is used when a
user logs on to the webpage with a username/password that doesn't exist in the database.
Idle
Idle level can't be selected but is automatically used when logged on to
the webpage without username an password.

11.11 Chipcard Settings
Figure 38: Chipcard Settings
You can use this menu to program or reprogram chip-cards. When creating a user on the chip-card you must make sure that the user is also in the database. If not the user will be identified as 'Unknown'. In this case you will have no privileges on the control-surface.
If you have a second control surface you can choose which modules chip card overrules the other.
If you have a combined 8-fader console you have to mark the setting "Control surface 2 chip card determines user level for control surface 1" for correct chip card functionality.
To program a chip-card simply type the username (max 32 characters) in the 'Chip card name' field. Type a password in the 'Chip card password' field (max 16 characters) and re-type the password in the 'Retype password' field (max 16 characters). Now press 'Write to Chip-card' and the data will be written to the chip­card.
To erase the chip-card simply blank out the username field and the password fields and rewrite the chip­card again.

FTP
Lyra Digital Mixer from D&R Phone +31 294 418014, email: info@d-r.nl Page 54
12 FTP
The Lyra also contains a FTP server (File Transfer Protocol) which may be used to transfer files from and to your PC. The information you can exchange is stored in three directories: Presets, Security, Flash. Depending on your rights given in the security section of the web-pages, you are able to browse and download/upload files. To do so, you can use a standard FTP-Client or even an Internet-explorer, be aware you can only open ONE connection to the FTP server at the same time (this causes an Internet-explorer sometime times to generate 'not found' messages because an Internet-explorer tries to use more connections at the same time).
12.1 Presets
The Preset directory contains the file 'Current Preset.Lyra' this file contains all information of the Lyra (except security and level settings). If you would get a snapshot of the Lyra's current situation (EQ, routing, remotes etc...) you can store this file on your FTP-client. If that file is restored, the Lyra will immediately jump to the settings in the file which is uploaded.
12.2 Security
The Security directory contains two files: 'Users.Lyra' and 'Levels.Lyra'.
The file 'Users.Lyra' stores all information like: Username, Password and security level. So if you want to transfer the list of Users to different Lyra systems you can use the file 'Users.Lyra'
The file 'Levels.Lyra' contains the information regarding the user levels. This file can be uploaded to different Lyra systems to get the same security level settings.
12.3 Flash
The Flash Directory holds several Firmware files. Those files are used for the internal software to run. If you need to update those files you must carefully follow the instructions supplied by the support engineer.
DON'T ACCESS THIS DIRECTORY WITHOUT INSTRUCTIONS OF A SUPPORT ENGINEER.
Lyra EQ Tool
Lyra Digital Mixer from D&R Phone +31 294 418014, email: info@d-r.nl Page 55
13 Lyra EQ Tool
The Lyra has a 3 band fully parametric equalizer. The gain can be adjusted on the control-surface. The gain for each band can be set independently on each channel. The other two parameters, Frequency and Bandwidth, are adjustable but are the same for all the channels.
To adjust the frequency and bandwidth parameters you can use the Lyra EQ Tool located on the CDROM.
Figure 42: Lyra EQ Tool
You can use your mouse to rotate the potmeter which changes the EQ parameters. It's also possible to use your mouse to pick up a white spot and move it around until you reach the EQ settings you want.
If you reach the preferred EQ setting you can save it to a file by using the File => Save menu. To implement the settings in the Lyra you have to use FTP to place the file inside the Flash directory. The EQ settings for each channel have to be altered at least once to take over the new EQ settings.
ActiveX Application
Lyra Digital Mixer from D&R Phone +31 294 418014, email: info@d-r.nl Page 56
14 ActiveX Application
The ActiveX application is a utility which allows you to control the Lyra from a remote area. The application is a graphical user interface which displays a combination of the 2 control-surfaces. You have exactly the same options as 2 control surfaces together.
Figure 43:The ActiveX application
In the picture above you can see an overview of all the module-settings from both of the control­surfaces together. The application works parallel with the control-surfaces. All the settings made through software or control-surface affect the other real-time.
To set the potmeter just left-click your mouse on it and hold your left button. Now move the mouse in the direction in which you want to move the potmeter. To reset the potmeters or fader to 0 dB position just double-click on it.
All the functionalities of the application are also programmable into scripts. This is very helpful for example to program multiple presets side by side. You need to have some knowledge about using the mixing console and about programming and/or scripting (e.g. Visual Basic).
You can find all the script-functions with explanation in the appendix and on the CDROM.

19 Appendix
19.1 Appendix A: Blockdiagram of the Lyra
The picture below represents the Lyra. Basically there are two main blocks. The Mixing Console and the I/O Matrix. The Mixing console is the section where all the audio-processing takes place.
The I/O Matrix is a very advanced matrix which gives you not only the possibility to route the busses to the outputs, but also the possibility to route any input directly to an output without interference from the Mixing Console.
The modules + external 1..2 come from the I/O Matrix and enter the Mixing Console where the audio is processed and routed to the busses. The busses exit the Mixing console to there dedicated outputs and back to the I/O Matrix where they can be routed to any output.
