Crossovers for subwoofers and loudspeakers
Crossovers play a crucial role in event technology: they break down an incoming audio signal optimally into different frequency ranges so that it can then be routed to specific speakers, speaker groups, or subwoofers. The purpose is to optimize different speakers and subwoofers for different frequency ranges and thus improve the efficiency and sound quality of the sound system. Discover a wide range of active crossovers in our online store to help you optimize the sound experience in your event location, restaurant, or conference room.
The various active crossovers in our range have filters that are used to isolate certain frequencies of a sound signal and forward them specifically to the corresponding speakers and subwoofers. The input signal passes through various filter processes within a crossover, which split it up. A low-pass filter passes on low frequencies while blocking higher frequencies. A high-pass filter, on the other hand, blocks low frequencies and passes higher frequencies to the speaker instead.
The crossovers in our assortment are also equipped with Bessel, Butterworth, and Linkwitz-Riley filters. The corresponding crossover offers you the following properties:
- • Bessel filters are known for their linear phase response. They do not distort frequencies, as all frequency components of the signal are passed through this filter simultaneously. This minimizes distortion. Bessel filters are used where phase fidelity is important, for example when transmitting music.
- • Butterworth filters have a flat amplitude response in the passband. In addition, there is no linear phase response. Crossovers with this type of filter are often used where the smoothest possible transmission in the passband is required.
- • Linkwitz-Riley filters are used in multi-way crossovers. They enable an effective transition between the different crossovers. In this filter, Butterworth filters are combined with special phase and amplitude relationships. This ensures that the signals in the different bands are seamlessly merged when overlapping. The filters are mostly used in professional applications, especially when several speakers and subwoofers – for example in PA systems – are connected to the crossover.
The is a digital speaker management system. The active crossover is equipped with Bessel, Butterworth, and Linkwitz-Riley filters, which offer a slope of up to 24 dB per octave. The controller also has four analog inputs, eight analog outputs, and a digital signal processor (DSP). This high-quality crossover enables a flexible output configuration for all common stereo and mono operating modes. The crossover can also be connected to a PC via USB.
The is also a digital speaker management system with two inputs and four outputs. This high-quality active crossover also enables a flexible output configuration for all available stereo and mono operating modes. Naturally, the controller has a digital signal processor (DSP) as well as Bessel, Butterworth, and Linkwitz-Riley filters.
