Precise equalisation control: Increase your sound experience with this 7-band graphic equaliser with a control range of ±12 dB and 7 individual equalization bands. Each band that ranges from 60Hz to 15kHz provides precise control over different frequencies to customize your audio output. This equalizer is made of original TL074 components from TI or ST and ensures high-quality sound adjustments for optimal performance Improved pre-amplification: the pre-amplification of this 7-band sound equalizer is powered by the classic operation amplifier 4580 and delivers 5x gain (14 dB). With an input impedance of 20K and an output impedance of 600 ohms, this equalizer guarantees powerful and clear audio output. Experience improved sound quality and higher volumes with this high-performance equalizer. Multifunctional interface: The 3.5 mm input interface of this equalizer supports 4-pin plugs and allows versatile connection options. The output port of the headset has a microphone and is therefore suitable for use with mobile phones for voice calls. In addition, another terminal with group lotus interface offers further connection options for different devices Compatible with various headphones: The sound equaliser has an ear amplifier section consisting of the NE5532 and contains a type 47 headphone driver circuit. This design allows for easy operation of different types of headphones and offers adjustable height and depth settings for individual sound preferences. Enjoy superior sound clarity and amplification with this versatile equalizer Durable construction and two-channel sound: the 7-band car sound equaliser made of aluminium alloy offers high strength, corrosion resistance and stable performance. Designed for everyday use in the car, this equalizer ensures long durability and reliable performance.
