Need help?Do you have a question about the DAPAudio PR-82 and is the answer not in the manual?
The DAP Audio PR-82 85W is a passive speaker designed for various audio applications, offering reliable sound reproduction and versatile installation options. This manual provides comprehensive instructions for its safe and effective use, from initial setup to ongoing maintenance and troubleshooting.
The PR-82 85W serves as a crucial component in an audio system, designed to convert electrical audio signals into audible sound. As a passive speaker, it requires an external power amplifier to operate, which processes the audio signal before sending it to the speaker. The speaker is equipped with an 8-inch woofer for low and mid-range frequencies and a 25.2 mm textile dome tweeter for clear high-frequency reproduction. This two-way design ensures a balanced and full-range sound output, making it suitable for a variety of environments where quality audio is essential. Its robust construction and careful design aim to deliver consistent performance and durability. The speaker is intended for indoor use, providing sound reinforcement in settings such as commercial spaces, educational facilities, or small to medium-sized venues.
The PR-82 85W is engineered for straightforward integration into existing audio setups. Before any operation, it is paramount to ensure that the power supply voltage matches the product's specifications to prevent damage. The speaker connects to a power amplifier using standard speaker cables, and maintaining correct polarity throughout the system is crucial for optimal sound quality and to prevent phase issues. The manual emphasizes the importance of using cables of the correct gauge, especially for longer runs, to minimize signal loss and ensure efficient power transfer.
Installation of the PR-82 85W offers flexibility. It can be mounted to various types of trusses using a clamp, providing elevated sound projection and optimizing coverage in larger spaces. Alternatively, it can be simply placed on a flat stage floor, offering a quick and easy setup for temporary or portable applications. When mounting, users must ensure the clamp is securely fastened and that the speaker's weight is adequately supported to prevent accidents. The device's design, as illustrated in the manual, indicates a compact and manageable form factor, facilitating its placement and integration into different aesthetic and functional requirements.
For optimal sound performance, careful consideration of the speaker's placement is advised. Factors such as proximity to walls, room acoustics, and the presence of sound-absorbing materials (like carpets or furniture) can significantly impact the sound quality. For instance, if the room has minimal sound absorption, excessive treble might lead to a "tinny" sound, requiring adjustments to the treble levels on the mixer or amplifier. Similarly, placing the speaker too close to a wall can cause the bass tones to bounce, resulting in distorted or "muddy" low frequencies, which may necessitate reducing the bass levels. Avoiding loud feedback from microphones is also highlighted as a critical operational practice to protect the speaker from damage.
The manual provides a clear setup diagram, illustrating how to connect the PR-82 85W to a mixer and a power amplifier. This involves connecting the mixer's output to the amplifier's input, and then connecting the amplifier's output to the speakers. This step-by-step guidance ensures that even users with limited technical experience can correctly configure their audio system. The speaker's impedance of 16 Ω is an important factor to consider when matching it with an amplifier, as incorrect impedance matching can lead to reduced performance or damage to the amplifier or speaker.
The DAP Audio PR-82 85W is designed for minimal maintenance, contributing to its longevity and reliability. The primary maintenance task involves keeping the unit clean. Users are instructed to disconnect the speaker from the mains power supply before any cleaning procedure to ensure safety. The cover should be wiped with a damp cloth, avoiding the use of alcohol or solvents, which could damage the finish or internal components. It is crucial never to immerse the speaker in liquid.
Maintaining clean connections is also vital for optimal performance. Periodically, users should disconnect electric power and wipe the audio connections with a damp cloth. Before reconnecting any equipment or supplying electric power, it is essential to ensure that all connections are thoroughly dry to prevent short circuits or other electrical issues. This simple practice helps to prevent signal degradation and ensures a stable audio connection.
The manual strongly advises against opening or modifying the device, as it contains no user-serviceable parts. Any unauthorized modifications will void the warranty and could lead to further damage or safety hazards. In the event of a malfunction or if the speaker fails to operate properly, users are instructed to discontinue use immediately and return the unit to their DAP Audio dealer for service. Repairs, servicing, and electrical connections must only be carried out by qualified technicians. This ensures that any necessary repairs are performed correctly and safely, preserving the integrity and performance of the speaker.
Should the speaker be dropped or struck, it is imperative to disconnect the power supply immediately and have a qualified engineer inspect it for safety before resuming operation. Similarly, if the system has been exposed to drastic temperature fluctuations, such as after transportation, it should not be switched on immediately. Allowing the system to reach room temperature before powering it on prevents potential damage from condensation.
The manual also outlines a clear return procedure for products requiring service or repair. Products must be sent prepaid in their original packing, clearly labeled with a Return Authorization Number (RMA number obtained from Highlite International B.V.). This ensures proper handling and tracking of returned items, facilitating efficient service. The customer is responsible for proper packing to prevent shipping damage, and any damage incurred due to inadequate packaging is not covered under warranty.
In summary, the DAP Audio PR-82 85W is a user-friendly and robust passive speaker designed for reliable audio output. Its usage features emphasize correct setup and placement for optimal sound, while its maintenance features focus on simple cleaning and professional servicing to ensure long-term performance and safety. Adherence to the instructions provided in the manual is crucial for maximizing the device's lifespan and ensuring a safe operating environment.
