Named after its early proponent audio engineer David Hafler, the circuit exploits the high amount of stereo separation between Left and Right channels and sound phase. [2] This type of system is called 2:2:4, since the rear channels are simulated from a two-channel stereo track, with no actual extra tracks encoded. The rear channels will ...
Point-to-point wiring is not suitable for automated assembly (though see wire wrap, a similar method that is) and is carried out manually, making it both more expensive and more susceptible to wiring errors than PCBs, as connections are determined by the person doing assembly rather than by an etched circuit board.
According to DIN EN 61140:2016 chapter 4.2 Table 1 (German version of EU standard EN 61140), Extra Low Voltage (≤ 50 V a.c. or ≤ 120 V d.c.) is defined as a sub-category of Low voltage (≤ 1000 V a.c. or ≤ 1500 V d.c.). This is similar to the definition provided in IEC 61140:2016. [7]
For example, NM 14-2 cable contains three conductors (two plus one ground) at 14 gauge, a size typically used for circuits protected at 15 amperes. Circuits with larger currents (such as for electric furnaces, water heaters, air conditioners, or sub-mains to additional circuit panels) will have larger conductors.
A loudspeaker is connected between the two amplifier outputs, bridging the output terminals. This doubles the available voltage swing at the load compared with the same amplifier used without bridging. The configuration is most often used for subwoofers. [2] For a given output voltage swing, the lower the impedance the higher the amplifier load.

Speaker wire is used to make the electrical connection between loudspeakers and audio amplifiers. Modern speaker wire consists of two or more electrical conductors individually insulated by plastic (such as PVC, PE or Teflon) or, less commonly, rubber. The two wires are electrically identical, but are marked to identify the correct audio signal ...
California’s Democratic Governor Gavin Newsom on Monday announced he is seeking up to $25 million in additional funding for legal fights with the incoming administration of U.S. President-elect ...
