While listening to the speaker sound, the right ear may hear the sound of the left speaker and the left ear may hear the sound of the right speaker. This effect overlap prevents head positioning when listening with headphones. There are a number of circuits that solve this problem by passing a semitone signal through a filter that provides some low-pass filtering and signal path delay (from one channel to another). Figure 1 shows the frequency response of 12 different crosstalk circuits. The low frequency filter varies from 200 Hz to 1000 Hz, and the low frequency attenuation changes from 0 dB to 12 dB. This article refers to the address: http:// Figure 1 Frequency response of 12 different crosstalk circuits The circuit shown in this article (Figure 2) is a series-feed input signal, while the low-pass filter and crosstalk amplitude are adjustable. This circuit does not have the high frequency rise of the signal inherent in most crosstalk circuits. Figure 2 Adjustable crosstalk circuit Crosstalk can be adjusted with frequency control VR1, VR4 and level control VR2, VR5. During tuning (by input switch SW1) only one stereo channel is fed into the circuit, which helps to position the sound reflection. Frequency and level controls allow you to change the spatial width of a solo instrument or solo. Crosstalk can be broken for true stereo recording or other surround sound sources. The op amp in the circuit can be compensated for gain 1 with any model, the op amp operates in the low frequency range, and its load is not important for producing apparently visible distortion. Any existing headphone amplifier can be used after volume control. â– (Lu)
H1Z2Z2-K Solar Cable is a type of cable specifically designed for use in solar power systems. It is commonly used to connect solar panels to inverters and other electrical components in a solar installation.

The H1Z2Z2-K designation refers to the cable's technical specifications. The "H1" indicates that it is a harmonized cable, meeting European standards. The "Z2" indicates that it is a halogen-free cable, which means it does not emit toxic gases when exposed to fire. The "Z2" also indicates that it is resistant to UV radiation, making it suitable for outdoor use in solar applications. Finally, the "K" indicates that it has a flexible copper conductor.
H1Z2Z2-K solar cables are typically insulated with cross-linked polyethylene (XLPE) or ethylene propylene rubber (EPR) to provide excellent electrical insulation and resistance to environmental factors such as sunlight, heat, and moisture. They are also often double-insulated for added safety.
These cables are available in various sizes and can handle different current ratings, depending on the specific requirements of the solar system. They are designed to withstand the harsh conditions of outdoor environments and have a long service life.
Overall, H1Z2Z2-K solar cables are essential components in solar power systems, ensuring efficient and reliable electricity transmission from the solar panels to the rest of the system.
When installing H1Z2Z2-K solar cable, it is important to follow the manufacturer's guidelines and local electrical codes to ensure proper installation and safety.
