4 In - 8 Out Speaker Management System
Introduction
WS-P48 is the flagship of Marani’ s digital speaker management systems. Designed for maximum
versatility, it provides all the processing and control necessary for both live and fixed installation use. It
offers 4 analog inputs, 8 analog outputs and 2 digital S/PDIF inputs, managed by a powerful DSP Engine, in
addition to high performance 24 Bit AD/DA converters. Each input channel provides a choice of EQ with 5band Parametric equalizer, Noise Gate function, Gain control and configurable Delay. In addition each
input includes Pink/White noise internal generator which may be used for tuning sound reinforcement
systems during installation. Each output offers up to 7-band of parametric equalization, in addition to the
crossover filters which themselves provide slopes from 6dB/Octave up to 48dB/Octave. Each output path
also features RMS compressor, Peak Limiter and configurable delay. The DPA480P supports a full matrix
mixing mode where inputs may be routed/mixed in any ratio to any output. For remote configuration and
control the DPA480 can be connected via Ethernet, USB or RS485. The control remote PC software
allows simultaneous control up to 32 units, setting all parameters and showing real time levels.

Described below are the functions of the front panel control buttons and encoders for the WS-P48.
Getting Started
As soon as the WS-P48 is turned ON the device model name will appear in the LCD screen:
WS-P48
Matrix 4x8
and a status bar will show the progress of the WS-P48 initialization process:
WS-P48
The WS-P48 will start with a completely “flat” condition of the all processes.
After the initialization, the WS-P48 will show on the LCD that no Program/Preset has been created yet and that
the program/preset loaded is an “empty” one, which means “flat” condition for the all available processes.
First time activation will default to the first of the “Empty Program”.
WS-P48
Default
Encoders and ENTER, ESC buttons
The WS-P48 is equipped with 3 Relative Encoders + Push Button function, “NAV/PM1”, “PM2” and “PM3”, where
the Push Button function is associated to the “ENTER”, “ESC” and “UTILITY” controls.
These encoders allow you to navigate the user interface and edit sections of the processor. They allow the user to
navigate within the screen for the selection of sub-menus, pages and parameters and to select the values to be
assigned during the editing operations.
The “ENTER” and “ESC” functions allow the user to confirm or NOT confirm the operations performed by the
encoders.
UTILITY, A/B/C/D and 1/2/3/4/5/6/7/8 buttons
The UTILITY button allows the User to enter the Sub-menus and set the general characteristics of the Processor.
The A/B/C and D buttons allow the User to enter the Editing Menus of the Processor's Input Channels and buttons
1, 2, 3, 4, 5, 6, 7 and 8, allow the User to enter the Editing Menus of the Processor's Output Channels.
The A/B/C and D buttons as well as the 1, 2, 3, 4, 5, 6, 7 and 8 buttons have double functions dependent on the
push and hold time.
When the A/B/C and D buttons are pushed and held for more than one second Input Channels A/B/C or D are either
muted or unmuted. The red LED will illuminate when the Channel is muted. When the “MUTE” LED is OFF, then
the related Input Channel is UN-MUTED.
A momentary push of the A/B/C and D buttons enters the Editing Mode for the Input Channels (see later for the
Input Channel Editing details).
The blue “EDIT” LED will now be ON.
When the 1, 2, 3, 4, 5, 6, 7 and 8 buttons are pushed and held for more than one second the Output Channels 1,
2, 3, 4, 5, 6, 7 and 8 are either muted or unmuted. The red LED will illuminate when the Channel is muted. When
the “MUTE” LED is OFF, then the related Output Channel is UN-MUTED.
A momentary push of the 1, 2, 3, 4, 5, 6, 7 and 8 buttons enters the Editing Menu for the Output Channels (see
later for the Output Channel Editing details). The blue “EDIT” LED will now be ON.
WS-P48 Menu and Sub-Menu Structures
As stated above, the start-up default screen is the following “Empty Program”:

From this point, sub-menus are accessed using the UTILITY”, “A/B/C/D”, “1/2/3/4/5/6/7/8”, “ENTER” and “ESC”
buttons and all parameters and values are navigated by the “NAV/PM1”, “PM2” and “PM3” encoders. Please refer

“High Cut Frequency”: the selectable frequencies range is from 20Hz to 20kHz.
Here, the NAV/PM1” encoder will increment/decrement the Frequency value by step of one thousand Hz, the PM2
by steps of one hundred Hz and the PM3 by steps of one Hz.
LPF sub-menu [Custom Filters]– from the sub-menu page, using the PM2 encoder, it is also possible to set the
LPF as “Custom Filter”, where this means that the LPF is builded as cascade of IInd Order Cells, which number is
depending from the filter's order and where for each Cell can be set independently the High Cut frequency and the Q.
More precisely, the available independent parameters for setting are the following:
1.
2.
3.
Customm_2nd: builded using 1 IInd order Cell, where High Cut Frequency and Q can be set
Customm_3rd: builded using 2 IInd order Cell, where High Cut Frequency can be set on both the cascaded
Cells and the Q on the second one
Customm_4th: builded using 2 IInd order Cell, where High Cut Frequency and the Q be set on both the
cascaded Cells.
The following is an example of a LPF sub-menu screen with the filter set at 400Hz as Custom_4th on Output1...
using the name “Low” (see later for assigning a Name to the outputs):
Out-1

LPF
->Custom_4th F = 400Hz
From this Page, to access the cascaded IInd order Cells, it is necessary to rotate the NAV/PM1 encoder Clockwise
or Counterclockwise.
The number of accessible IInd order Cells is depending from the Custom Filter order: Custom_2nd will allow the
editing of just one IInd order Cell, Custom_3rd and Custom_4th, the access to 2 IInd order Cells.
In the previous example, rotating Clockwise the NAV/PM1 encoder, we can access the Filt1 (Cell1) and Filt2 (Cell2)
pages, for the Cells High Cut Frequency and Q settings.
When within the Filt1 editing Page, in example:

Input and Output Channels Last Edited Parameter Return Function
Once you have escaped out of parameter editing within the individual Input or Output channels the WS-P48 will
remember this last editing action on that Channel. When you return for your next editing action pressing the EDIT
button on that channel will immediately return you to the screen related to this last editing action.
This function makes fine tuning or modifying easier when it is necessary to make a number of adjustments to the
same parameter in a short time sequence.
Input Channels and output Channels LINK Function
The WS-P48 is able to perform a unique LINK MODE between Input Channels as well as a link between Output
Channels to enable quick and immediate editing (you cannot link output to input channels).
To link channels when editing, you will need to select a “Master” channel that will be the one to be edited and have
it’s parameters displayed on the LCD screen. You can then select and link other channels (Slaves) that you wish
to apply the same changes to.
To enter a link mode session, select the Master channel Edit mode, then link the Slaves by pressing their related
Edit buttons.
All Linked channels will be selected ready for adjustment when their “Blue” LED is lit in the Editing mode.
Now all Slave channels and only those selected will modify their parameters accordingly as you edit the Master
channel.
All other existing parameters will stay the same within the Slave Channels unless edited by this link with the
Master channel.
Note: The LINK function is NOT a COPY function.
If we want to edit the limiter of the Output channels 1/2/4, we can enter the editing mode of Output Channel 1 by
pressing the related Edit button and turning on the Blue LED below the Output Channel 1 LED meters. This
assigns the “role” of Master and displays this channel’s parameters on the LCD:
Out-1
A: 5ms
Name
Limiter
R: 0.2s +5.0dB
Then press the Edit button of Output Channels 2/4, turning on their related “Blue” LED’s. Now all parameters
edited on Output Channel 1, will also be applied to channels 2 and 4.
If we want to remove one of the linked channels from the Link, press the related Edit button.
Exiting the editing of the Master channel during a Link session will automatically terminate that session. The Link
will also be automatically terminated if, during the editing of Output Channels you jump across to begin editing an
Input channel or vice versa.
Factory Reset
In the event of the password being lost or any other reason the user may require the unit to be reset to the
original factory settings, a "Factory Reset" that will clear all settings of the WS-P48 and return the device to the
original factory setting, is available to the user.
Note: Continuing with this process will mean the WS-P48 will re-initialize to the original factory settings and any
previously stored information and changed parameters will be permanently lost.
Note1: Together with the all information, also the current password will be lost after a “Factory Reset” and will
be replaced with the Factory one: “000000”.
In case the customer forgot the password and need to reinitialize it, can use the “Factory Reset” to put the
Password at its original “000000” value.
Use the following procedure to perform the factory reset:
1.
2.
While the WS-P48 is switched OFF, simultaneously press the ENTER+ESC+UTILITY buttons on the front
panel.
Maintain pressure on all three buttons as you turn the power switch to On and the following LCD screen
appears on the WS-P48:
Please Wait......
Memory Reset
3.
Release the buttons and wait for the WS-P48 to re-initialize.
Once completed, the WS-P48 will resume regular operation as though it was a new unit from the factory and no
previously programmed parameters will be available for use.
GND and USB LIFT switches
The WS-P48 on its back panel is providing a couple of switches allowing to connect or left unconnected the power
Supply Main GND and the USB connectors GND to the chassis.
MAIN “LIFT/GND” Switch - Actually can happen that sometime it is necessary to NOT connect the Main Ground
to the Chassis in order to avoid GND loops.
This is possible using the “MAIN” GND/LIFT switch.
When the switch is positioned on GND, the Main Power Supply GND is connected to the Chassis.
USB and RS485 “LIFT/GND” Switch – When using a USB or RS485 remote control connection, can be that the
GND of the USB ocable it is not connected to the remote controller GND.
In this case it is necessary to provide it from the processor's side, and this can be done selecting the GND position
with the USB/RS485 switch.
On the other hand, if the GND of the USB or RS485 cable is already connected to the remote controller GND, to
connect the same ground also to the GND of the processor could create GND loops or generate GND noises.
In this case, the switch on the position “Lift” will leave the cable GND not connected to the chassis of the WS-P48
USB Remote Control protocol for Presets Changing and Gain/Volume controls
The following is the HEX Code for controlling the WS-P48 recall presets and master volume control:
Preset Changing:

Input Gain and Output Volume Control:
UPDATE GAINS-PHASE: CMD=01H
A. The User has to send the following Command, including the value to be assigned to “Vol”, for modifying the Input
Gain (Chn = 0, 1, 2, 3) or the Output Volume (Chn = 2, 3, 4, 5, 6, 7, 8, 9).
Also the Output signal Phase can be modified:

XX = 0,..,31 (ID device)
Chn=0,...,7: Channel selected, 0, 1, 2, 3=In1, In4; 2,...,9=Out1,..,Out8; when Channel 0, 1, 2, 3 selected, then Vol=Input
Gain, when Channel 2, 3, 4, 5, 6, 7, 8, 9 selected, then Vol= Output Vol.
Phs= Phase only if the Chn>1; Value=0, 1 where 0=direct, 1=inverse (180')
Vol= Gains from 0 to 180 (-12dB/ +6dB step 0.1dB)
B. If the command has been properly executed and the Gain/Volume modified, then the microcontroller will send
back to the User (eg Crestron/AMX Remote Control..) the same frame used by the command:
