1. INTRODUCTION
WPE 24 is a digital signal processor with external control capability. Its compact
design and format make it perfect for use by audiovisual integrators.
The device has balanced inputs and outputs to give them greater immunity
against electromagnetic interference.
The external control of this device is done thanks to its Ethernet connectivity,
which can be done through the dedicated WorkCAD3 software or through OSC
commands by third-party devices.

Analog audio input
The connection of the input signal to the device can be balanced or
unbalanced. Keep in mind that balanced signals provide 6 dB more level than
unbalanced signals of equal amplitude.
UNBALANCED
BALANCED
Analog audio output
The analog audio output of the device can be balanced or unbalanced
according to the selected extraction mode. To do this, keep in mind the following
types of connection:

3.3.1. Main supply input
Power input for external source. The admitted voltage can be between 12/24
Vdc, with a minimum current of 500 mA.
Check the current polarity before connecting the main supply
The external power supply is not provided with the device.
4. 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 it will have access to all the functionalities of the
device and you can also see the interaction of your device with the rest of the
BlueLine Digital MKII network elements.
4.1.1. Setup through WorkCAD3 Configurator
After making the configuration at the IP level of the device and updating it if
necessary (see WorkCAD3 Configurator user manual), proceed with its
configuration.

Compressor and Noise Gate.
▪Threshold. Limiter threshold.
▪Times. Attack and Release times for the Compressor.
▪Ratios. Ratios for Noise Gate and Compressor.
5. OSC COMMANDS
WPE 24/44 accepts OSC commands and ASCII commands via UDP, if you need
more information about OSC protocol you can click on the next link.
http://opensoundcontrol.org/introduction-osc
The next list shows OSC and ASCII commands, for the OSC commands the form
to send them will depend on the App that be used, on the list bellow you can
see all the OSC commands with its syntax: path, type of data and data.
For the ASCII commands we use the same syntax that OSC commands, with the
difference that the commands begin with “//”, and the separation between
path, type of data and data is ”;”.
For the selection of input and outputs through OSC/ASCII commands you should
use the way below:
Single selection x
Group selection, one by one
[x,y,z,…]
Group selection, from-to
[x-y]
