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.

On the front of the device you will find a display through which you can view or modify different parameters of the unit.
To navigate between the different parameters press the NEXT button. If you want to edit any of these parameters, press the SET button to access it. Next, specify which parameters are editable and which are not:

LEVELS, not editable
STATIC IP, editable
DYNAMIC IP, not editable
MAC, not editable

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:

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

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:

– 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.

-Output processor:

• EQUALIZER. It has 15 filters applicable to each of the outputs. To apply them, select the band (filter number), the type of filter, the frequency, the gain and the Q factor. It It is also possible to apply a filter by using the mouse and acting on the points that appear in the image and represent the 15 available filters.

MATRIX. In this section you can choose the weighted sum of the inputs to be sent to each output. The input of each input can be entered both graphically and numerically.
For each input the option of Mute and Invert is available.

• XOVER: In this section you can apply crossover filters on the selected output. We have high pass filter and low pass. We must select the cut-off frequency (20Hz-20KHz), filter order (eighth maximum) and filter type (Butterworth, Linkwitz-Riley, Bessel). For Linkwitz-Riley filters the orders increase by two.

• DELAY. In this section a delay of up to 8.19 ms can be applied to the selected output.
  This value can be entered both graphically and numerically. The units of measurement can be samples, ms, meters and feet.

DYNAMICS. A Limiter / Compressor / Noise Gate is available for each output.

• Enables. Field dedicated to the activation of the Limiter, Compressor and Noise Gate.
• Limiter Threshold. Limiter threshold.
• Compressor Times. Attack and Release times for the Compressor.
• Ratios. Ratios for Noise Gate and Compressor.

• Presets. Allows to manage the presets and the starting mode of the device.

• RENAME. Allows to rename the preset selected previously.

• RECALL. Allows to load the selected preset

• SAVE. Allows to save the configuration of the selected preset.
  EXPORT. Allows to export all presets to a file with the .wpf3_wpe_preset extension. The information not saved in a preset will not be exported.

• IMPORT. Allows to import all presets from a file with .wpf3_wpe_preset

• Startup preset. Allows to manage the starting method of the device.

• Last Loaded. The device will start from the last load preset.

• Last LIVE. The device will stsart with the configuration when it was turned off.

4.2 Project saving and synchronization with the devices

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
