    Frequently Asked Questions about LC7i Pro

    What are the main features of the Audiocontrol LC7i Pro?

    The Audiocontrol LC7i Pro offers six channels with active speaker inputs that support a maximum input voltage of up to 40 V, enabling powerful signal transmission. With fixed and variable outputs featuring discrete level controls, you can precisely manage the signal. The AccuBASS® processing corrects bass roll-off, ensuring clear sound. A load selection switch and GTOTM signal detection provide flexible customization options. The grounding isolation switch enhances audio quality by reducing noise, and the compact design makes it easy to place in the vehicle. This is complemented by an integrated ACR-1 dashboard remote control.

    How do I install the Audiocontrol LC7i Pro in my car?

    When installing the Audiocontrol LC7i Pro, it is important to consider the compact design with dimensions of 17.8 cm (L) x 12.9 cm (W) x 2.9 cm (H). These dimensions allow the High-Low Adapter to fit in numerous vehicles without taking up much space. Choose a dry location for mounting to avoid moisture damage and ensure that all cables are correctly connected for optimal signal transmission. The ACR-1 dashboard remote should be installed within easy reach for convenient access. Note that the current draw is 330 mA and a Fuse of 2 A is recommended.

    How does the AccuBASS® processing improve the sound of the LC7i Pro?

    The AccuBASS® processing in the Audiocontrol LC7i Pro corrects bass roll-off that often occurs in factory audio systems when the volume is increased. This technology automatically detects when the bass decreases and adjusts the signal curve accordingly to optimize bass reproduction. This prevents the loss of important low frequencies. For you, this means that even at higher volumes, a powerful and precise bass is maintained, enhancing your music performance. Also important is the signal-to-noise ratio of over 124 dB, which minimizes further interference.

    What power specifications does the Audiocontrol LC7i Pro have?

    The Audiocontrol LC7i Pro has a total distortion of only 0.01%, allowing for highly precise sound reproduction without audible distortion. The impressive signal-to-noise ratio of over 124 dB ensures outstanding clarity and purity of the audio signal by effectively reducing interference. The frequency response of the adapter ranges from 20 Hz to 20 kHz, meaning it can process a wide range of frequencies to reproduce all details of the music clearly and accurately. The maximum output level is 9.5 Vrms, ensuring that the audio signal is transmitted to the amplifier unit without power loss.

    How does the GTOTM signal detection work in the LC7i Pro?

    The GTOTM signal detection of the Audiocontrol LC7i Pro allows for automatic activation of the device as soon as an audio input signal is detected. This eliminates the need for separate turn-on signals or wires, significantly simplifying installation. This feature works in conjunction with audio detection and the remote input, so you can be sure that the adapter will always activate when a signal is needed. The adapter also provides a 12V DC remote output that is activated as soon as the device is turned on, allowing you to control additional devices in the setup without extra effort.

    What input and output impedances does the LC7i Pro offer?

    The Audiocontrol LC7i Pro offers versatile options for impedance settings at its inputs: you can choose between 20 Ω, 60 Ω, and 20 kΩ, depending on the specific requirements of your audio system. This flexibility allows for optimized adaptation to different sources to ensure the best possible signal transmission. At the six preamp outputs, which feature four main and two bass channels, the output impedance is only 150 Ω. This low impedance ensures that signal losses during transmission are minimal, leading to high-quality sound reproduction.

    What is the maximum input level supported by the Audiocontrol LC7i Pro?

    The Audiocontrol LC7i Pro is capable of processing a maximum input voltage of 40 Vrms. This high input voltage capacity allows for smooth signal transmission even with very powerful audio systems. The ability to handle up to 400 watts with an input impedance setting of 20 kΩ gives you the assurance that the adapter will seamlessly integrate into your existing system. Additionally, support for up to six speaker-active channels ensures that complex audio setups can be managed effortlessly without experiencing any loss of performance.

    What is the maximum output level of the LC7i Pro?

    The maximum output level of the Audiocontrol LC7i Pro is 9.5 Vrms or up to 13 V peak. This output power allows you to pass the audio signal at a high level to your amplifier or another device without worrying about signal loss or distortion. In practice, this means that even with dynamic music pieces, all nuances are preserved, and the overall performance of the audio system is optimally utilized. The variable output gain with a range of +/- 15 dB offers additional flexibility to perfectly adjust the system to your individual listening preferences.

    What audio qualities does the LC7i Pro offer with its technical parameters?

    With a total harmonic distortion of 0.01%, the Audiocontrol LC7i Pro ensures precise and clean audio playback. The outstanding signal-to-noise ratio of over 124 dB guarantees that interference and noise are minimized, ensuring crystal-clear sound quality. The frequency range of 20 Hz to 20 kHz supports the entire spectrum of audible frequencies, allowing every detail of your music to be experienced. With the ability to process high input levels of up to 40 Vrms and deliver outputs of up to 9.5 Vrms, the adapter offers both flexibility and the highest signal quality.

    Does the Audiocontrol LC7i Pro also fit in my car?

    Due to its compact dimensions of 17.8 cm (L) x 12.9 cm (W) x 2.9 cm (H), the Audiocontrol LC7i Pro can also find its place in vehicles with limited space. These dimensions ensure that the adapter can be installed with minimal effort without compromising the functionality of your vehicle. Since it is designed independently of specific car brand requirements, it can be flexibly installed in various vehicle models. Make sure that the current draw of 330 mA does not overload your system's power and that the recommended fuse rating of 2 A is provided to ensure smooth operation.
