Audison AP4 D Four-channel Class D amplifier Prima series

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 ohm, guaranteeing high-quality audio performance. Its fully bridgeable Class D design allows flexible configurations, enabling the amplifier to be used in both four-channel and two-channel (bridged) mode for 260 W x 2 at 4 ohm.

The AP4 D is equipped with high and low level inputs that support a wide range of audio sources. 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 different audio system configurations. Total harmonic distortion (THD) is kept below 0.1% at 100 Hz and 4 ohm, guaranteeing clear and precise sound. The wide frequency response range from 10 Hz to 30 kHz and the signal-to-noise ratio of 100 dBA guarantee detailed and interference-free sound reproduction. The damping factor of 170 at 1 kHz contributes to optimal speaker control, improving bass response.

The amplifier is also equipped with intelligent power management, with an idle consumption of just 1 A and a minimum consumption of only 0.05 mA. The supply voltage ranges from 7.5 to 15 VCC, making it suitable for installation in vehicles with different power characteristics. In summary, the Audison Prima AP4 D is an excellent choice for those who wish to enhance their audio system with a versatile and powerful amplifier, capable of delivering superior audio performance in any situation.
