INTRODUCTION

WPE 44 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.

WORK WPE 44 Digital Audio Processor - ACTIVE PRESET

LEVELS, It shows the signal level present in the inputs and outputs. It is the default screen of the device and to which it returns after 10 seconds without editing a screen. Next to each input/output a bar will appear, marking the level according to the attached chart:

Number of bars Level (dBFS)
8 -3 dBs/ 0 dBs
7 -6 dBs/ -3 dBs
6 -9 dBs / -6 dBs
5 -18 dBs / -9 dBs
4 -26 dBs / -18 dBs
3 -40 dBs / -26 dBs
2 -60 dBs / -40 dBs
1 -80 dBs / -60 dBs
None < 80 dBs

STATIC IP, this is the static IP address. The device has a static IP address by default in the subnet 10.0.0.0/8. For editing, use the buttons SET (to select and set the digit) and
NEXT (for editing upwards).

NOTE: After a change, the device restarts to confirm the value.
NOTE: ENABLED by default

DYNAMIC IP, this is the dynamic IP address of the device, which is assigned by a DHCP server.
NOTE: DISABLED by default. Only displayed when selecting this mode by software.

MAC. this is the physical address of the device.

ACTIVE Preset. Allows to select one of the 8 presets available.

3.1 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.

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.
If you click with the left mouse button on the device, the configuration interface will open where the following parameters appear:

Configurator

– VIEW

  • DSP. It allows to choose the visualization of the processing fields.
  • Preset button. It allows to manage the presets and the starting mode of the device.

– MASTER: It allows the modification both graphically and numerically of the general volume control of the device. In addition, it has a MUTE button.
– DSP Area: It is the area where the processing of the inputs and outputs of the device is configured

  • Input and output selection field. It allows to choose the I/O on which you want to work. The parameters to control will vary depending on whether an input or Output has been chosen
  • Gain. Field that allows controlling the volume or inverting the polarity of the selected I/O.

Inputs processor:

  • EQUALIZER. It has 4 filters applicable to each of the entries. To apply them, we must select the band (filter number), the type of filter, the frequency, the gain and the Q factor.
    It is also possible to apply a filter using the mouse and acting on the points that appear in the image and represent the 4 available filters.

OSC COMMANDS

WPE 24/44 accepts OSC commands and ASCII commands via UDP, if you need moreinformation 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 themwill depend on the App that be used, on the list bellow you can see all the OSC commandswith its syntax: path, type of data and data.
For the ASCII commands we use the same syntax that OSC commands, with the differencethat the commands begin with “//”, and the separation between path, type of data and datais ”;”.
For the selection of input and outputs through OSC/ASCII commands you should use the waybelow:

Single selection x
Group selection, one by one [x,y,z,…] Group selection, from-to [x-y]

Default UDP port (Foreign/Local) = 9000
