Controllers & crossovers


From controlling power amps and speakers to special effects on instruments, controllers have a wide range of uses. They provide easier handling of sound equipment by, for example, connecting to multiple speakers and then controlling them as one unit. The speakers now operate as one entity. Controllers are also available as special effect machines for guitars and keyboards.

Our crossovers too are necessary devices in order to achieve the perfect sound quality! They differentiate from a mixer incoming signals into high and low frequencies and then pass them on to the speaker. Low frequencies get send to a woofer and high frequencies to a tweeter. If not already built into your speaker, you should definitely consider investing in one.
