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

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.

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.

The Input page is entered without any request of Password and is freely accessible by the User. Together with the Input Page, also the main functions of presets saving/storing and loading/recalling are accessible on a top bar, so as a SETUP control for setting the PDA500P module operative mode. Also a LOCK button is available for making active the Output Channels Editing pages (under Password) and a Compression/Limiting Master edigint page (also under Password). Finally a Side Bar showing a Vu-Meters section is displayed.

The top Bar and the Vu-Meters Section, will be EVER available also from the Output Editing pages and Compression/Limiting page, accessible under Password.

TOP BAR

From the Top Bar, the following actions can be taken

LOAD Preset: pressing this button, a standard page for selecting a directory on the Pc from where to load a Preset on the DSP, will open. The user can load from the selected directory a preset which will become the current conﬁguration (Input and Outputs setting and Operative Mode) run by the DSP.

SAVE Preset: pressing this button, a standard page for selecting/creating a directory where to save a Preset on the Pc, will open. The user can save within the selected directory the current edited conﬁguration (Input and Outputs setting and Operative Mode) and assign to Preset the desired NAME.

STORE Preset: the PDA500P has the possibility to store within its on board Eeprom up to 8 Presets

recallable by the back panel Encoder. From the Pc Sw is possible to store within the PDA500P Eeprom the 8 presets, naming them as desired and allocating them in locations numbered from 1 to 8, with the desired sequence. Pressing the STORE Preset button, a particular page for naming and assigning a location within the DSP board's Eeprom, will open

RECALL Preset: From the Pc Sw is possible to recall from the PDA500P Eeprom any of 8 presets, there where presets were previously stored following the STORE Preset procedure. Pressing the RECALL Preset button, a particular page for will open

The user can recall from the selected position within the DSP board Eeprom a previously stored preset and making it the currently ran by the DSP and the currently edited in its parameters by the Pc Sw.

The user can store within at the selected position within the DSP board Eeprom (position assigned by the Select Position scroll window) the currently edited setting with the desired name, assigned within the EDIT NAME frame. Selected directory the current edited conﬁguration (Input and Outputs setting and Operative Mode) and assign the the Preset the desired NAME. A name with up to 16 characters lentgh can be assigned
