Product details
The Power Dynamics PMDA4500 is a compact 1U Class-D power amplifier designed for four-zone public address systems. Its four zone outputs provide separate volume control, while switching power technology supports efficient operation with reduced power consumption and heat generation.
When no input signal is detected for one minute, the amplifier automatically enters standby mode to conserve energy. It resumes operation when a signal is detected.
Protection mechanisms include short-circuit, overload, high-temperature, clipping and DC protection. The amplifier is suited to public address installations in banks, town halls, supermarkets, schools, hotels, restaurants, shopping centres and other public spaces.
