A sound source such as a compact disc player or radio may be connected to a PA system so that music can be played through the system. Smaller, battery-powered 12 volt systems may be installed in vehicles such as tour buses or school buses, so that the tour guide and/or driver can speak to all the passengers.
Diagram showing a Hafler circuit. The Hafler circuit is a passive electronics circuit with the aim of getting derived surround sound or ambiophony from regular stereo recordings without using costly electronics. Such circuits are generally known as matrix decoders. The Dynaquad system works using similar principles. [1]
A DJ gets his decks ready as the speaker cabinets are set up and readied for a dance event. A challenge with designing sound systems for clubs is that the sound system may need to be used for both prerecorded music played by DJs and live music. A club system designed for DJs needs a DJ mixer and space for record players. In contrast, a live ...
A line array is a loudspeaker system that is made up of a number of usually identical loudspeaker elements mounted in a line and fed in phase, to create a near-line source of sound. The distance between adjacent drivers is close enough that they constructively interfere with each other to send sound waves farther than traditional horn-loaded ...
Enclosures designed for use in PA systems, sound reinforcement systems and for use by electric musical instrument players (e.g., bass amp cabinets) have a number of features to make them easier to transport, such as carrying handles on the top or sides, metal or plastic corner protectors, and metal grilles to protect the speakers.
In some small to mid-size venues, such as bars and nightclubs, the PA system may not have the capacity to provide the bass sound for the venue, and the PA system may be used mainly for vocals. Bass players in bands that play at a variety of venues, including these types of small to mid-size venues, may need to be able to provide the bass sound ...
The bridge mode option is often used in PA systems and especially in car audio applications to feed bass loudspeakers at high power. Car audio amplifiers commonly have only a notional 13.8 volt supply, which would ordinarily limit the voltage swing available at the output to + and − 6.9 volts.
Audio multicore cables are used to convey many audio signals between two locations, such as in audio recording, sound reinforcement, PA systems and broadcasting. [1] Multicores often route many signals from microphones or musical instruments to a mixing console , and can also carry signals from a mixing console back to speakers.
