Frequently Asked Questions about LOC-22

Welche Stromversorgung verwendet der LOC-22?

The LOC-22 from JL Audio uses a switching MOSFET PWM regulated power supply. This type of power supply allows for stable operation between 9 and 16 V DC, enabling flexible integration into various audio setups. The standby power consumption is less than 1.6 mA, while in active operation only 0.13 A at 13.8 V is required. The integrated clipping indicator significantly facilitates the adjustment to different amplifier output signals, as it works with test tones or music. These features make the LOC-22 particularly efficient and user-friendly in installation as well as in everyday operation.

Welchen Frequenzgang bietet der LOC-22?

The LOC-22 from JL Audio offers a flat frequency response of 3 Hz to 32 kHz, with a precision of +0 dB and -1 dB. This allows for exceptional sound reproduction, especially at high signal levels, without compromising bass performance. Especially when you prefer music with strong bass, the sound quality remains unchanged, which is often not the case with many passive converters. The analog circuit architecture ensures that the frequency response provides a consistent and high-quality audio experience even at high output levels.

Kann der LOC-22 hohe Eingangsspannungen verarbeiten?

Yes, the LOC-22 can handle input voltages of up to 40 V RMS per channel, which corresponds to about 400 watts at 4 ohms. This capability allows it to process the most powerful factory amplifier outputs without distortion. The differential symmetrical input architecture also minimizes the risk of induced noise. These features make the LOC-22 ideal for integration into existing high-power factory audio systems that have specific requirements for signal processing.

Wie funktioniert die automatische Einschaltung des LOC-22?

The LOC-22 offers two methods for automatic activation: DC offset detection and signal capture. In DC offset detection, the presence of a DC voltage of 4.5 V is utilized, while the signal capture responds to a minimum output voltage of 5 mV On/3.5 mV Off at 1 kHz. This versatility allows for seamless integration into various audio systems without the need for additional circuits or relays. The LOC-22 generates a positive 12V activation output to turn on aftermarket amplifiers or other connected devices.

Welche Signalverarbeitungseigenschaften hat der JL Audio LOC-22?

The LOC-22 impresses with a purely analog circuit design that ensures realistic signal processing. It features two different signal processing channels with a gain range from -27.3 dB at full CCW to +3.2 dB at full CW. With a signal-to-noise ratio of 118 dB at minimum and 103 dB at maximum gain, the LOC-22 enables outstanding sound quality. Harmonic distortion is minimized to just 0.01% at 2V RMS at a frequency of 1kHz, supporting clean and clear audio playback. Its capability for differential signal processing prevents unwanted interference and enhances the overall sound experience.

Wie wird der LOC-22 in ein bestehendes Audiosystem integriert?

For the integration of the LOC-22 into an existing audio system, the dimensions are crucial: With a height of 31 mm, a width of 120 mm, and a depth of 77 mm, the LOC-22 should easily fit into most standard audio setups. The analog RCA connectors allow for easy connection to most signal processors and amplifiers. Thanks to the differential balanced input method, the LOC-22 can seamlessly couple with various audio components by converting existing factory signal outputs into signals usable for aftermarket amplifiers. When installing within your vehicle's audio system, a 1 A fuse, preferably fast-acting, is required.

Welche Verbindungstypen sind mit dem LOC-22 kompatibel?

The LOC-22 supports unbalanced analog outputs via stereo RCA connectors, covering a wide range of amplifiers and signal processors for audio applications. The maximum output voltage is 8V RMS, allowing the LOC-22 to support even demanding audio systems. The output impedance is 450 Ω, which represents a low load for connected devices. The LOC-22 also processes input channels differentially balanced, implying an input impedance of typically 20kΩ. This versatility in connection compatibility ensures effective and interference-free integration into various audio systems.

Welche Schutzmaßnahmen bietet der LOC-22?

The LOC-22 is equipped with several protective measures to ensure stable performance. The primary ones include a regulated MOSFET power supply that maintains a constant operating voltage between 9 V and 16 V, and an overload protection mechanism. The recommendation of a 1 A fast-blow fuse protects the device from overvoltage. With a current consumption of only 0.13 A at 13.8 V, efficient operation is ensured. Additionally, the differential signal processing significantly reduces the risk of noise emissions.

Wie leistungsstark ist der Line-Ausgangskonverter LOC-22 von JL Audio?

The LOC-22 line output converter is powerful, as it is equipped with a regulated frequency response of 3 Hz to 32 kHz and an input voltage capacity of 40 V RMS per channel. It offers a maximum unencapsulated output power of 8V RMS. With a signal-to-noise ratio of up to 118 dB and a THD+N of 0.01% at 2V RMS (1kHz), it demonstrates the ability to provide a clean and distortion-free audio experience. Its differential-balanced architecture further allows for the control of induced cable noise and ensures that the audio signal remains untouched throughout the entire processing.

Welche Vorteile bietet der LOC-22 in der Audiowiedergabe für Fahrzeuge?

In terms of vehicles, the LOC-22 offers several advantages in audio playback. Thanks to its ability to accept high input voltages of 40 V RMS per channel, even the most powerful factory amplifier outputs can be converted without any issues. Complete analog processing ensures precise sound reproduction without losses at higher levels. The available RCA outputs are also compatible with the most common amplifiers and signal processors. Due to its automatic turn-on methods, the LOC-22 adapts flexibly to different activation signals in the vehicle, ensuring seamless integration into the existing audio units.
