Wireless microphone receiver racks backstage at a large televised music awards event Wireless microphone and radio receiver. There are many types of receiver. True Diversity receivers have two radio modules and two antennas. Diversity receivers have one radio module and two antennas, although some times the second antenna may not be obviously ...
Photo: 2.5 mm mono (TS), 3.5 mm mono and stereo (TRS), and 1 ⁄ 4 inch (6.4 mm) stereo (TRS) phone connectors The most common microphone connector in consumer use is the venerable phone connector, in 1 ⁄ 4 inch (6.4 mm), 3.5 mm, and 2.5 mm sizes, and in both mono and stereo configurations.
As an analogy, the hub of the rotary woofer's fan is somewhat like a helicopter's swashplate which allows a stationary source of reciprocating motion—the voice coil of the subwoofer—to change the angle of the spinning set of blades. Many DIY rotary woofers use a RC helicopter swashplate connected to a modified traditional subwoofer driver ...
Fans attached to components are usually used in combination with a heat sink to increase the area of heated surface in contact with the air, thereby improving the efficiency of cooling. Fan control is not always an automatic process. A computer's BIOS can control the speed of the built-in fan system for the computer. A user can even supplement ...
A wireless microphone transmits the audio as a radio or optical signal rather than via a cable. It usually sends its signal using a small radio transmitter to a nearby receiver connected to the sound system, but it can also use infrared waves if the transmitter and receiver are within sight of each other.

Before the bass management system, there is a LFE channel. After the bass management system, there is a subwoofer signal. A common misunderstanding is the belief that the LFE channel is the subwoofer channel. The bass management system may direct bass to one or more subwoofers (if present) from any channel, not just from the LFE channel. Also ...
The transient generated when a microphone is hot-plugged into an input with active phantom power can damage the microphone and possibly the preamp circuit of the input [10] because not all pins of the microphone connector make contact at the same time, and there is an instant when current can flow to charge the capacitance of the cable from one ...
Home-cinema systems typically use one subwoofer cabinet (the "1" in 5.1 surround sound). However, to "improve bass distribution in a room that has multiple seating locations, and prevent nulls with weakened bass response, some home-cinema enthusiasts use 5.2- or 7.2- or 9.2-channel surround sound systems with two subwoofer cabinets in the same ...
