The DAP Audio PR-52 50W is a passive speaker designed for various audio applications, offering reliable performance and straightforward operation. This manual provides essential information for safe installation, setup, operation, and maintenance of the device.
Function Description
The PR-52 50W is a 2-way passive speaker system, meaning it requires an external amplifier to function. It is designed to reproduce audio signals with clarity and a balanced frequency response. The speaker can be used in various settings, including fixed installations, stage monitoring, or as part of a larger sound system. Its robust construction allows for flexible mounting options, either on a truss using a clamp or placed on a flat surface.
Important Technical Specifications
- Power Consumption: 50W RMS, indicating its continuous power handling capability.
- Impedance: 16 Ω, which is important for matching with appropriate amplifiers to ensure optimal performance and prevent damage.
- Woofer: 5.25", responsible for reproducing low and mid-range frequencies.
- Tweeter: 12.6 mm Mylar Dome Tweeter, designed for clear high-frequency reproduction.
- Frequency Range (-10 dB): 50 Hz - 20 kHz, covering a wide spectrum of audible frequencies for full-range sound.
- Connections: Speaker cable connector IN, providing a standard input for connecting to an amplifier.
- Color: Black, offering a discreet aesthetic that blends into most environments.
- IP Rating: IP20, meaning it is protected against solid objects larger than 12.5 mm but has no protection against water. It is therefore intended for indoor use and should be kept away from rain and moisture.
- Dimensions (LxWxH): 170 x 180 x 235 mm, making it a compact and manageable size for various installations.
- Weight: 4 kg, contributing to its portability and ease of handling.
Usage Features
The PR-52 50W is designed for ease of use and integration into existing audio setups.
- Installation Flexibility: The speaker can be mounted to any type of truss using a clamp (not included) or simply placed on a flat stage floor, offering versatility in placement.
- System Integration: The manual provides a clear diagram illustrating how to connect the PR-52 speakers to a DAP Audio GIG-104C mixer and a P-400 power amplifier. This demonstrates a typical setup for a multi-speaker system.
- Connection Guidelines: Users are instructed to connect the mixer to the power amplifier, then the power amplifier to the speakers using appropriate speaker cables, and finally connect the power supply to both the mixer and the amplifier. This ensures a correct and safe signal flow.
- Signal Level Management: It is crucial not to set the input signal level higher than required for full output, as extreme frequency boosts can lead to overdriving and potential damage to the equipment. Users are advised to reduce the input signal level if overdriving occurs.
- Polarity Maintenance: Maintaining correct polarity throughout the entire system using cables with clear color indication is emphasized for optimal sound quality.
- Feedback Avoidance: Users are warned to avoid loud feedback from microphones, as this can damage the speaker.
Maintenance Features
The DAP Audio PR-52 requires minimal maintenance to ensure its longevity and optimal performance.
- Cleaning: The unit should be kept clean by wiping the cover with a damp cloth. It is important not to immerse the speaker in liquid or use alcohol or solvents, as these can cause damage. All audio connections should also be wiped with a damp cloth and ensured to be thoroughly dry before reconnecting equipment or supplying power.
- Connection Integrity: Regularly checking and maintaining clean connections is vital for preventing poor sound quality and potential damage.
- Pre-Operation Check: Before initial start-up, users should inspect the unit for any transportation damage. If damage is found, the dealer should be consulted, and the system should not be used.
- Environmental Considerations: The speaker should only be used indoors and kept away from water, other liquids, flames, and flammable materials. Avoid operating the system immediately after drastic temperature fluctuations, as condensation can cause damage.
- Troubleshooting Guidance: The manual includes a troubleshooting section for common issues like "No Sound" and "Sound Warping." For "No Sound," users are advised to check all cable connections, power supply, and the speakers themselves. For "Sound Warping" (distortion), adjusting treble and bass levels is recommended, especially considering room acoustics.
- Professional Servicing: The device contains no user-serviceable parts. All repairs, servicing, and electrical connections must be carried out by qualified technicians. Unauthorized modifications or attempts to service the unit by unqualified personnel will void the warranty and could lead to further damage or safety hazards.
- Packing for Return: In case of a return, it is crucial to pack the unit securely, preferably in its original factory box and packing material, to prevent shipping damage. An RMA number must be obtained from Highlite International B.V. before returning any merchandise.
