    Frequently Asked Questions about AP 4.380


    How does the 4/3/2 channel configuration of the Focal AP 4.380 Amplifier work?

    The Focal AP 4.380 offers a versatile channel configuration that allows the amplifier to operate in 4, 3, or 2 channels. In 4-channel mode, it delivers 4x70 watts RMS at 4 Ohm or 4x95 watts at 2 Ohm. The 3-channel mode uses a bridging mix, delivering 190 watts to a Subwoofer. The 2-channel mode, also known as Bridged-Tied-Load (BTL), allows two channels to be combined, outputting a total of 2x190 watts RMS at 4 Ohm. This flexibility is ideal for various audio system demands, especially when you prefer different speaker configurations in your car.

    What impact does the Class A/B amplification of the Focal AP 4.380 have on sound quality?

    The Class A/B amplification of the Focal AP 4.380 combines the best of both worlds: the high audio quality of Class A with the efficiency of Class B. This hybrid amplifier circuit reduces distortion while consuming less power and still maintains very high sound fidelity. With a signal-to-noise ratio of over 82 dB and total harmonic distortion of ≤ 0.06 percent, clear and precise sound is ensured. This configuration is particularly beneficial if you prefer sound details and dynamics, especially at high volumes, without compromising audio quality.

    How do the crossover settings on the Focal AP 4.380 support optimal audio performance?

    The crossover settings in the Focal AP 4.380 significantly enhance sound control. The integrated high-pass and low-pass crossovers provide precise frequency control. The high-pass crossover at 75 Hz (CH1/2) is crucial for separating frequency ranges suitable for smaller speakers to prevent distortion at low frequencies. The low-pass crossover between 40–300 Hz (CH3/4) supports the delivery of low frequencies to Subwoofers, resulting in more intense bass reproduction. These settings allow you to specifically cater to your preferences and speaker requirements.

    What parameters improve bass reproduction in the Focal AP 4.380?

    The Focal AP 4.380 Amplifier includes various features to optimize bass reproduction. A key role is played by the bass boost function, which can be adjusted in three levels: 0, 6, and 12 dB on channels CH3-4. This adjustment allows for an additional boost of the bass frequencies for sound expansion, especially when using a subwoofer. Particularly if you enjoy listening to music loudly, this control ensures clear, punchy bass without loss of quality. Together with the low-pass crossover at 40 - 300 Hz, this substantially improves low-frequency reproduction.

    What role does the full-range mode play in the Focal AP 4.380?

    The full-range mode in the Focal AP 4.380 is considered essential for the even reproduction of the entire frequency spectrum. No frequencies are favored or suppressed, ensuring a linear frequency response from 10 to 30 kHz. This is particularly useful when you want to achieve a homogeneous sound image across different types of speakers without diminishing certain frequency ranges. This generates a realistic sound image, which is especially important in complex musical pieces.

    What are the dimensions of the Focal AP 4.380 and what does that mean for installation?

    With dimensions of 56 x 235 x 262 mm and a weight of 2.4 kg, the Focal AP 4.380 is compact enough to be discreetly installed in the vehicle. This size offers enough flexibility in placement, whether under the seat or in the trunk, without overly restricting space. Thanks to the compact design, installation is made easier, which is particularly advantageous in vehicles with limited space. Ensure that the location provides adequate ventilation to avoid overheating.

    What frequency response does the Focal AP 4.380 offer and how does that affect the sound?

    With a frequency response of 10 - 30 kHz, the Focal AP 4.380 covers a wide range of the audio band spectrum, resulting in a dynamic and detailed sound. This bandwidth allows you to reproduce both low and high frequencies accurately, which is particularly beneficial for complex musical pieces. The high upper limit of 30 kHz ensures that even the finest details remain audible, while the low lower limit effectively supports deep bass.

    How is the total harmonic distortion of the Focal AP 4.380 minimized?

    The Focal AP 4.380 keeps total harmonic distortion (THD) extremely low, with a maximum of only 0.06 percent. This low THD value ensures distortion-free sound reproduction, providing clean and clear tones. Even at high volumes, the audio quality remains consistent, allowing for an enjoyable listening experience in demanding listening environments. The technological design of the Amplifier minimizes internal distortions, optimal for you when sound fidelity and details are crucial.

    What power does the Focal AP 4.380 provide at different impedances?

    The Focal AP 4.380 Amplifier delivers different output power depending on the impedance. At 4 Ohm, it offers 4x70 watts RMS, and at 2 Ohm, the power increases to 4x95 watts RMS. In Bridged-Tied-Load mode at 4 Ohm, 2x190 watts RMS are provided. These flexible power options allow you to choose the one that best suits your speakers and audio needs. These power options are ideal for achieving an optimal balance between volume and sound quality.

    How easy is it to install the Focal AP 4.380 in different vehicle types?

    Thanks to its compact dimensions of 56 x 235 x 262 mm, the Focal AP 4.380 is easy to install in most vehicles. While specific vehicle models are not mentioned in the description, the compact size is advantageous for vehicles with limited space. Installation can be done under the seat or in the trunk. It is important to ensure adequate ventilation to avoid overheating and ensure longevity. Flexible placement options make installation easier in a variety of car models.
