- The Audison Prima AP4 D is a four-channel Class D amplifier, designed to expand the capabilities of the AP 4.9 bit and AP 5.9 bit amplifiers. With a total power of 520 W, it delivers 4 x 130 W at 2 ohms, ensuring high-quality audio performance. Its fully bridgeable Class D design allows for flexible configurations, enabling the amplifier to be used in both four-channel mode and two-channel (bridged) mode for 260 W x 2 at 4 ohms. The AP4 D is equipped with both high and low-level inputs, supporting a wide range of audio sources. The input sensitivity can be adjusted between 1.5 and 4.5 V RMS for Pre-In inputs, and between 3 and 9 V RMS for Speaker-In inputs, ensuring perfect compatibility with various audio system setups. Total harmonic distortion (THD) is kept below 0.1% at 100 Hz and 4 ohms, delivering clear and precise sound. The wide frequency response range from 10 Hz to 30 kHz and the signal-to-noise ratio of 100 dBA ensure detailed sound reproduction free from interference. The damping factor of 170 at 1 kHz contributes to optimal speaker control, enhancing bass response. The amplifier also features intelligent energy management, with a no-load consumption of only 1 A and idle consumption at just 0.05 mA. The power supply voltage ranges from 7.5 to 15 VDC, making it suitable for installation in vehicles with varying power characteristics. In summary, the Audison Prima AP4 D is an excellent choice for those looking to enhance their audio system with a versatile and powerful amplifier, capable of delivering superior audio performance in any situation.
