The PDA500P on the front panel offer the possibility
to select up to 8 presets, edited and uploaded on the
unit through a Rotary encoder.
The Presets can be created thanks a Pc Sw which
controls the unit via a RS485 interface.
The PDA500P can be put in network with twin
modules and controlled within a single Pc interface.
The PDA500P is a powerful Class D BiAmp module for
active cabinets, allowing the user to process the
Input signal with first class 24bit/96kHz DSP
processes, both for filtering purposes and dynamic
ones.
The all DSP processes can be accessed by the
cabinets' manufacturer for the specific acoustic
characterization of the cabinet itself,and by the user
for the application personalization.
For the Cabinets' manufacturers, 5 paramteric filters
(Peaker or Variable Q Shelving) are available on the
Input path of the signl, so as a RMS compressor
operating on both Low/High outputs, and fed by the
Low output path signal.
On the Low/High ways, Lp/Hp filters up to 48dB/Oct
are available, so as up to 15ms Delay, one firs/second
order All Pass filter for phase control purposes, 5
parametric filters (Peaker or Variable Q Shelving ),
RMS compressor and Clip Limiter.
The all processes available to the manufacturers
(Factory) are under Password.
On the PDA500P Panel, a Master Input Gain is
available for the simultaneous level control of the
input level control; 3 leds are indicating the Input
Signal presence, the Limiter activity and the Power
On/Off of the unit.

Operating Mode
The PDA500P can work as a stand alone unit [Stand Alone Mode], where up to 8 preset can be recalled by
directly selecting them through the 8 positions encoder available on the front panel, or can work as completely
remotely controlled unit [Remote Control Mode].
As soon as is turned ON the device will load the currently selected preset, depending from the current
position of the Preset Eq encoder.
The Power Led will turn ON (Red) and the unit will be ready to work.
Stand Alone Mode
When the PDA500P is operating as stand alone unit, so running one of the 8 available presets, previously
created and stored within the unit with the remote control PC SW, the only available control are the 8 “preset
encoder”, allowing to select 1 of the 8 available presets previously stored through the PC SW Remote Control.
In Stand Alone Mode, the only indications of the “Activity” of the PDA500P in terms of running processes and
signal status, can be checked thanks to the Signal Led, indicating if Signal is present at the module Input and
the Limit Led indicating when on, if the DSP is dynamically compressing/Limiting the audio signal and indicating
an Input Clip condition when blinking.
The Input Signal can be sent to the unit through any one of the Male/Female XLR connectors.
The one not used can be used for mirroring the Input signal to an other unit.
The available potentiometer can help to control the Signal Input Level.
Remote Control Mode
When the PDA500P is operating as stand alone unit, so running one of the 8 available presets, previously
created and stored within the unit with the remote control PC SW, the only available control are the 8 “preset
encoder”, allowing to select 1 of the 8 available presets previously stored through the PC SW Remote Control.

PC Sw Remote Control Operations
The PDA500P can be controlled by a Remote Control Sw running on Pc, allowing to fully edit the all processes
available on each channel of the PDA500P.
More, once created the desired configurations and selected the desired processes, the complete set up can
be stored within the PDA500P and recalled later on as preset also when the unit is working in Stand Alone
Mode.
Once launched the Pc Sw Remote Control, previously installed on Pc (for the installation it is enough to run the
“Installation Sw” and to install also the USB driver which installation instruction are on the CD containing the
Remote Control Sw and coming with the PDA500P), the following screen shot will appear on the Pc:
The screen above is allowing to set the RS485 connection parameters.
With the
RS485: the RS485 connection has to be selected when the PDA500P is connected to the PC through the
RS485 line.
In this case the PDA500P will be controlled as one of a NET of chained units, being allowed the net control of
more units when using the RS485 connection.
In the RS485 mode (chosen by “checking” the RS485 button on the “Communication Port” frame), need to
assign the proper “COM” port in order to match the COM port assigned by the Pc to the “USB to Serial Port”
within the Device Manager window at the “Ports (COM&LPT)” directory.
When selected the RS485 connection, more PDA500P can be connected all together.
In order this to happen, need the all units (connected in net and up to 32) to be identified by DIFFERENT ID
number.
In order the units to have a different ID, need to pre-assign to the all units used in net a specific ID number.
When selected the RS485 mode, this can be done connecting one by one the units to be used in net and
assigning to anyone of them an ID through the “Configure ID Device” button.
When a Unit is connected, pressing the “Configure ID Device” it is possible to enter a window allowing to
assign to the unit the ID number.
NOTE: for avoiding problems is highly suggested to work with COM ports number within the 10.
