Frequently Asked Questions about AP 4.380

What are the technical specifications of the Focal AP 4.380 Amplifier?

The Focal AP 4.380 is a 4-channel Class A/B amplifier. It offers a CEA power of 4x70W RMS at 4 Ohm and 4x95W RMS at 2 Ohm. In BTL mode, it delivers 2x190W RMS at 4 Ohm. The frequency response range is 10 - 30kHz with a total harmonic distortion of ≤ 0.06%. The signal-to-noise ratio (SNR) is over 82dB at 1W/A. Additional features include a high-pass filter at 75Hz for channels 1/2, a low-pass filter from 40 - 300Hz for channels 3/4, and a bass boost of 0/6/12dB for channels 3-4. The amplifier supports full-range mode.

In what configurations can the Focal AP 4.380 be amplified?

The Focal AP 4.380 amplifier can be used in various configurations: in 4-channel mode, it offers 4x70W RMS at 4 Ohm or 4x95W RMS at 2 Ohm; in 3-channel mode, one channel can be bridged; and in 2-channel mode, 2x190W RMS at 4 Ohm is available. This provides flexibility to adapt to different audio setups, whether you are looking for clear stereo sound or powerful amplified Subwoofer performance. This amplifier allows for customization based on vehicle and personal listening preferences.

What crossovers does the AP 4.380 offer and what purpose do they serve?

The Focal AP 4.380 features both high-pass and low-pass crossovers to efficiently amplify different frequency ranges. The high-pass filter is set at 75Hz for channels 1/2, while the low-pass filter for channels 3/4 can vary between 40 and 300Hz. These adjustment options allow for precise control of speaker frequencies, enabling you to utilize optimal frequencies for each speaker type. This not only keeps the sound clear and detailed but also protects the speakers from excessive strain in certain frequency ranges.

What are the dimensions of the Focal AP 4.380 amplifier?

The Focal AP 4.380 Amplifier has compact dimensions with a height of 56mm, a length of 235mm, and a depth of 262mm. These measurements of 213/64 x 91/4 x 105/16 allow it to be easily integrated into the vehicle interior without taking up excessive space. Weighing 5.3 lbs or 2.4 kg, the amplifier is also lightweight and can be flexibly installed in various vehicle types. The compact dimensions facilitate placement even in limited spaces or in vehicles with restricted installation areas.

What bass boost options does the Focal AP 4.380 offer?

The Focal AP 4.380 Amplifier features a bass boost specifically set for channels 3-4. You can choose between 0dB, 6dB, and 12dB to optimally adjust the bass reproduction to your listening preferences or the acoustic conditions of your vehicle. This setting allows for targeted bass enhancement without compromising the overall sound balance. This function is particularly useful when you have larger speakers or Subwoofers in use that can benefit from additional bass enhancement to achieve a powerful and deep sound experience.

What sound dynamics does the Focal AP 4.380 Amplifier support?

The Focal AP 4.380 maximizes sound dynamics through its A/B classification. This amplification technology combines the detailed noise suppression of Class A with the efficiency of Class B. As a result, it not only delivers an impressive frequency response of 10 - 30kHz but also a minimal distortion factor of ≤ 0.06%, leading to an incomparably clear and dynamic listening experience. Thanks to this technology, high frequencies can be reproduced crystal clear while providing solid bass foundations, making the amplifier the ideal choice for discerning music lovers.

How can the AP 4.380 Amplifier be integrated into a car radio?

The Focal AP 4.380 can be easily integrated into an existing car radio system by connecting it to the RCA input of the radio. This connection allows for direct signal transmission from the car radio to the amplifier, utilizing the full amplification of the A/B-Class amplifier. Access and placement in the car are important; the compact dimensions of the amplifier facilitate installation even in tight spaces. Detailed planning, taking into account the spatial conditions, is beneficial to ensure a seamless integration.

What signal-to-noise ratios does the Amplifier AP 4.380 offer?

The Focal AP 4.380 offers an impressive signal-to-noise ratio (SNR) of over 82dB at 1W/A. This technical feature significantly contributes to a clear and distortion-free audio experience, as it effectively reduces unwanted background noise. A high SNR is particularly important in quiet music passages, as it ensures sound quality is maintained with minimal interference. Such a high signal-to-noise ratio allows you to enjoy the full quality and detail of your audio content even in challenging listening environments, without being distracted by noise signals.

What power can the AP 4.380 deliver at different ohm settings?

The Focal AP 4.380 Amplifier shows remarkable performance across various ohm settings. At a 4 ohm configuration, it delivers a CEA power of 4x70W RMS, ideal for standard speaker systems. At a 2 ohm setting, the power increases to 4x95W RMS, making it excellent for more dynamic and powerful audio setups. In bridged mode (BTL), it then achieves an impressive 2x190W RMS at 4 ohm. This power flexibility allows for excellent adaptability to the speaker technology, regardless of the specific requirements of your speaker configuration.

How does the A/B Class amplifier technology of the AP 4.380 affect the listening experience?

The AP 4.380 Amplifier from Focal utilizes A/B Class amplification, which offers an ideal balance between audio quality and efficiency. This technology delivers an enhanced sound profile by manually combining Class A with the energy efficiency of Class B. At maximum sound dynamics, the amplifier provides detailed highs and solid lows. Especially when you enjoy listening to music at high volumes, the signal reproduction remains clear and distortion-free. The A/B Class ensures that even at high volumes, precise music reproduction is maintained, making the Focal AP 4.380 an excellent option for audiophiles.
