The DPA616 delivers robust and consistent audio amplification across multiple zones with minimal distortion and optimal signal integrity. Its energy-efficient Class-D topology reduces heat build-up, allowing for prolonged operation without the need for extensive ventilation. The unit is particularly well-suited to applications requiring high channel density with space-saving rack configurations. Users benefit from simple setup, intuitive gain controls, and extensive protection features that guarantee long-term reliability.
Q: Can the DPA616 be used to drive 100V line speaker systems?
A: No, the DPA616 is designed for low-impedance speaker loads (4Ω or 8Ω) and is not compatible with constant voltage (100V) speaker lines without external transformers.
Q: What are the benefits of Class-D amplification in this model?
A: Class-D amplification offers high efficiency and reduced heat output, which makes the amplifier more energy-efficient and reliable in continuous operation.
Q: Is it possible to bridge channels for increased output?
A: Yes, the DPA616 supports bridged mode operation, allowing two channels to be combined to deliver higher output power into 8Ω loads.
Q: How is the amplifier protected from damage?
A: The DPA616 includes comprehensive protection against overheating, short circuits, DC faults, overload, and signal clipping.
Q: What type of environments is the DPA616 ideal for?
A: It is ideal for fixed installations in large buildings such as schools, retail centres, corporate facilities, and hotels where multiple zones require independent amplification.
