1. INTRODUCTION
The devices of the BlueLine Digital MKII series allow the streaming of audio over IP through
Ethernet, complying with the TCP / IP protocol stack. Using the BlueLine Digital MKII system
it is possible to perform from a simple point-to-point audio transmission to a complex multi-
channel system with alarm control and management.
BlueLine Digital MKII can make use of the existing physical network infrastructure in the
installation, due to its low bandwidth consumption. On the other hand, it is compatible with
commonly used low or high impedance amplification systems.
Thanks to the modular design of the system, BlueLine Digital MKII adapts perfectly to the
features of each installation, being able to expand the system in the future if the
characteristics of the installation require it.
Features:
•Management of audio strteamers and receivers.
•Different types of coding (PCM, MP3).
•Different audio extraction modes (Dual, Single, Mono).
•Control by OSC commands.
•Control by GPIO.
•Complement with the family of Light Mouse devices.
•Real-time system monitoring.
•Configuration by software.
•External power supply or PoE.

2. Components of the BlueLine Digital MKII System
In this chapter you will find information about the different devices that make up the BlueLine
Digital MKII system.
The BlueLine Digital MKII system has four kinds of devices:
STREAMERS
BLS2 LITE MKII
One stereo channel sender
BLS2 SD MKII
One stereo channel sender with SD player
RECEIVERS
BLR2 LITE MKII
One stereo channel receiver
BLR2 MKII
One stereo channel receiver with 2xGPIs/2xGPOs
BLR2 A plus MKII
One stereo channel receiver with
2xGPIs/2xGPOs and low impedance amplifier
PAGING
SPS 8
Paging station
WALLMOUNT
CONTROLLERS
BLC 1
Wallmount controller for local receiver
WNC 1
Wallmount controller through the network
WAC 7
Customizable wallmount controller
Note: The BlueLine Digital MKII series is compatible with the previous series of devices, so you
can include devices of both series in your installation.
3. RECEIVERS
The BlueLine MKII receivers are devices that are responsible for extracting one stereo audio
channel from the network. There are three types of receivers:
BLR2 LITE MKII: Receiver of one stereo channel.
BLR2 MKII: Receiver of one stereo channel with 2GPIs / 2GPOs.
BLR2 A PLUS MKII: Receiver of one stereo channel with amplification module and 2xGPIs /
2xGPOs.
BlueLine receivers do not consume bandwidth by audio transmission. Its consumption is
associated with UDP / OSC state packets and OSC control packets. This consumption will be
disregarded, since it is minimal and it will depends on each specific use.

Audio extracting methods
It is important to emphasize that each audio receiver is only capable of extracting one stereo
audio channel from the network. The extraction of this channel can be done in different ways,
that can be select in the configuration interface of WorkCAD3 Configurator.
Stereo extraction mode. Each input is assigned to its output.
Individual extraction mode. Of the two parts that one stereo channel is conformed (1-L or 2-
R), we choose one of them, to extract it by both outputs of the receiver. In this example we
select 1-L
3.1.1.
DUAL
3.1.2.
SINGLE

BLR2 MKII
USER MANUAL
VERSION 1.0
BLUELINE DIGITAL MKII SERIES www.workpro.es 6
Mono extraction mode. The two input channels (1-L and 2-R), are summed to extract them by
both outputs of the receiver.
6 dB are subtracted from each output to compensate for the electrical sum of two input
channels.
Inversion of the polarity for output 2, in order to create a balanced output. This option is only
available for SINGLE and MONO modes. In this case, we select MONO mode.

4. BLR2 MKII
The BLR2 MKII is an audio over IP receiver, that can extract one of the channels transmitted
by the Blueline MKII senders.
Also, the BLR2 MKII includes 2xGPIs (pull-up) and 2xGPOs (open collector). The device can
be powered by either PoE or an external power supply.
It is important to stress, that one receiver cannot mix channels from different senders.

General Purpose Inputs Outputs, the device includes 2xGPIs and 2xGPOs.
-GPIs: Inputs that senses logic voltage variations, in order to send UDP/OSC control
commands when a variation occurs. A typical configuration would be the connection
of a push button between one GPI and GND, so when the push button is pressed the
UDP/OSC commands programmed are sent to the network.
-GPOs: Outputs in open collector configuration, which once activated let flow current
through them. A typical configuration would be the interconnection of the coil of a
relay.
RJ45 port for LAN connection. Allows PoE power (Class 0 802.3af).
Next to the RJ45 connector you will find two LEDs indicating the status of the device:
LINK (green)
Indicates that the BLS2 Lite MKII is connected to the LAN
ACT (orange)
Indicates that packets are being sent or received
This port allows the connection of a BLC 1 wall controller acting as a local controller. In this
way, it is possible to select the audio source to be extracted and its volume.
Power input for external source. The admitted voltage can be between 12/24 Vdc, with a
minimum current of 500 mA.

The external power supply is not provided with the device.
Device setup
The configuration of the device can be done by software (WorkCAD3 configurator) or through
display. The most comfortable way for the user is through WorkCAD3 configurator, since he
will have access to all the functionalities of the device and he can also see the interaction of
the device with the rest of the BlueLine Digital MKII network elements.
After making the IP level configuration of the device and updating it if would be necessary
(see WorkCAD3 Configurator manual), proceed with its setup.
If you click on the device with the left mouse button, the configuration interface will be opened
and the following parameters will appear:
-Zone: This field refers to the zone to which the device belongs, in order to receive
OSC control commands. By default, all BlueLine receivers are in zone 1.
-Generate Ding Dong: Button to execute a Ding Dong signal in the receiver. It is useful
to recognize/check the speakers connected to this receiver.
-Channel: Number of the stereo audio channel that we want to extract.

-Controller´s offset: Field to enter an offset in the wallmount controller (BLC 1 or WNC
1) that manage the device. For example, if we enter "1" in this field, the minimum
channel that can be chosen in the wall-control will be "1", so if we have a reserved
source in channel "0", the user will not be able to access it.
