Frequently Asked Questions about Prima AP4 D (B-Ware)


What performance specifications does the Audison Prima AP4 D Amplifier offer?

The Audison Prima AP4 D offers impressive performance specifications. It delivers a total power of 520 W. The power can reach 4 x 130 W @ 2 Ohm in 4-channel operation, while in 2-channel bridged mode, 260 W x 2 @ 4 Ohm is possible. These power values are achieved at a supply voltage of 14.4 VDC. With a damping factor of 170 @ 1 kHz and a distortion (THD) of 0.1% at 100 Hz and 70% rated power, it ensures clear and powerful sound output. The efficiency of Class D technology allows for high power in a compact design.

What makes the Audison Prima AP4 D particularly suitable for installation in audio applications?

The Audison Prima AP4 D is particularly notable for its Class D technology, which delivers high power with low distortion. The Amplifier can easily complement integrated systems as it supports both high-level and low-level inputs. With a compact design and a weight of 1.33 kg, it is easy to install. The possibility of full bridging and the optional use with Audison AP 4.9 bit and AP 5.9 bit Amplifiers makes it versatile. The input variability allows for adjustment to different signal levels from 1.5 to 9 V, facilitating integration into various systems.

What bandwidth does the Audison Prima AP4 D support?

The Audison Prima AP4 D supports an impressive bandwidth ranging from 10 Hz to 30 kHz at -3 dB, 2 VRMS, and a load of 4 Ohm. This extensive bandwidth enables the reproduction of deep bass as well as high frequencies, meaning the Amplifier is capable of providing a full and dynamic sound spectrum. This is particularly beneficial for audiophiles who appreciate faithful music reproduction. Through precise build quality and tonal fine-tuning, the audio material is reproduced as realistically as possible.

What energy efficiency does the Prima AP4 D offer when it is in the off state?

The energy efficiency management of the Prima AP4 D is extremely advantageous. The standby consumption in the off state is only 0.05 mA, indicating that it consumes very little energy in the off mode. This is particularly relevant for users who leave their audio components in the vehicle for extended periods without use. Even when the amplifier is in standby, the vehicle battery is only minimally burdened. This feature makes the Prima AP4 D an environmentally friendly and economical solution in the field of car audio amplification.

Does the Audison Prima AP4 D fit my vehicle?

The Audison Prima AP4 D amplifier is suitable for a variety of vehicles thanks to its compact dimensions and universally optimized input systems. To ensure it fits in your vehicle, you should check the dimensions and technical requirements. The supply voltage of 7.5 to 15 VDC allows flexibility with the power source, and the impedance support of 2 ohms per channel facilitates use in most common speaker systems. Make sure to leave enough space for cooling, as this is important for optimal performance utilization.

What installation instructions are there for the Audison Prima AP4 D?

The installation of the Audison Prima AP4 D should be done thoughtfully to ensure optimal performance. Due to its compact size and high-level input function, it can be easily integrated into existing systems. Pay attention to the voltage requirements of 7.5 to 15 V and ensure that the inputs are properly configured to avoid overvoltage. Additionally, it is important to adhere to ventilation provisions to prevent overheating. Filter settings must be individually adjusted to the specific speaker configuration to maximize sound quality.

What advantages does the Class D technology of the Prima AP4 D offer?

The Prima AP4 D takes advantage of Class D technology by combining high power and energy efficiency. This results in low heat generation and allows for more compact designs. Unlike traditional amplifier classes, Class D offers a higher conversion efficiency of electrical energy into acoustic energy. The amplifier can utilize its high performance with a low current draw of 27 A at full music power. This efficiency is particularly beneficial in mobile installations, as less power is drawn from the vehicle battery, allowing for longer listening times.

How does the Prima AP4 D affect the sound in an audio system?

The Prima AP4 D significantly improves sound by enabling clear and distortion-free amplification of audio signals. The damping factor of 170 increases control over the speakers, resulting in more precise bass and clearer highs. With a signal-to-noise ratio of 100 dBA, it ensures clean sound, free from unwanted background noise. Since the amplifier covers a bandwidth of 10 Hz to 30 kHz, the entire frequency spectrum is represented in detail, which is particularly beneficial for complex musical pieces.

What are the main input options on the Prima AP4 D?

The Prima AP4 D Amplifier features flexible input options, such as Hi-Level and Low-Level inputs, which are useful for integration into almost any audio system. The pre-in sensitivity can be set between 1.5 - 3 - 4.5 V RMS, while the speaker-in also offers an adjustable sensitivity of 3 - 6 - 9 V RMS. These adaptability features allow compatibility with different source devices without negatively affecting signals. The PRE IN RCA connections ensure a fast and lossless connection, which directly impacts audio performance and guarantees optimized sound quality.

How does the Prima AP4 D control remote connections?

The Audison Prima AP4 D efficiently controls remote connections via the Remote IN function. The required control voltage ranges from 7 to 15 VDC at 1 mA current draw. This remote function allows for easy integration into system configurations where versatile control options are essential. It can be activated via an existing control line from source devices or directly from the vehicle's computer. This versatility provides a simple solution for users who want to incorporate their amplifier into more extensive audio setups without sacrificing convenience or flexibility.
