3. Setup
Proper setup is crucial for optimal performance and safety. Follow these steps to connect your DPA260P unit.
3.1 Cunnessione di putenza
- Assicuratevi chì l'interruttore di alimentazione di l'unità sia in a pusizione OFF.
- Connect the supplied AC power cable to the IEC inlet on the rear panel of the DPA260P.
- Plug the other end of the power cable into a suitable AC power outlet (AC 90-240V, 50/60Hz).

- Ingressi: Connect your audio source (e.g., mixing console) to the two analog input XLR connectors labeled "INPUTS A" and "INPUTS B" on the rear panel.
- Outputs: Cunnette u vostru amplifiers or powered speakers to the six analog output XLR connectors labeled "OUTPUTS 1" through "OUTPUTS 6".
- Ensure all audio cables are securely connected and are of high quality to prevent signal loss or interference.
3.3 Control Connections (USB/RS485)
- For remote configuration and control, connect the DPA260P to a computer using a USB cable via the USB port on the front panel, or use the RS485 connections on the rear panel for multi-unit control.
- Install the dedicated PC control software (typically provided with the unit or available for download from the manufacturer's website) on your computer.
4. Operating Instructions
The DPA260P offers extensive control over your audio signal. This section outlines the basic operation and key functionalities.

4.1 Cuntrolli Front Panel
- Display LCD: Shows current settings, menus, and real-time levels.
- Navigation Buttons (NAV/PREV, ENTER, ESC, UTILITY): Used to navigate through menus, select options, confirm settings, and exit menus.
- Parameter Knobs: Adjust various parameters such as gain, frequency, Q, and delay.
- Misuratori di livellu d'entrata/uscita: Provide visual indication of signal levels for both inputs and outputs. Monitor these to prevent clipping (indicated by the "CLIP" LED).
4.2 Basic Signal Flow and Processing
- Input Processing: Each input channel (A and B) features an 11-band Parametric EQ, gain control, noise gate, RMS compressor, and configurable delay. Adjust these parameters to optimize the incoming audio signal.
- Matrix Mixing: The DPA260P supports a full matrix mixing mode, allowing you to route and mix inputs to any output in any desired ratio. This is essential for creating custom speaker configurations.
- Output Processing: Each of the six output channels offers up to 5-band parametric equalization, crossover filters, peak limiter, and driver alignment delay.
- Filtri crossover: Configure high-pass and low-pass filters to correctly route frequencies to specific speakers (e.g., subwoofers, mid-range, tweeters). Select filter types (Butterworth, Bessel, Linkwitz-Riley) and slopes (6dB/Octave to 48dB/Octave) based on your speaker specifications.
- Peak Limiter: Set the peak limiter threshold to protect your speakers from excessive signal levels.
- ritardu: Use the output delay to align drivers in multi-way speaker systems or to time-align speakers in different physical locations.
4.3 Cuntrollu di u Software di PC
For advanced control and real-time monitoring, utilize the dedicated PC software. This software allows for simultaneous control of up to 32 units, providing a comprehensive interface for setting all parameters and viewing real-time levels. Refer to the software's help documentation for detailed instructions on its features and usage.
5. Mantenimentu
To ensure the longevity and reliable performance of your Marani DPA260P, follow these simple maintenance guidelines:
- Pulizia: Regularly wipe the unit with a soft, dry cloth. Do not use abrasive cleaners, solvents, or waxes, as these can damage the finish and internal components.
- Ventilazione: Ensure that the ventilation slots on the unit are not obstructed. Proper airflow is essential to prevent overheating.
