Amplifier-to- loudspeaker connection method that converts a stereo amplifier into a monoblock power amplifier. One amplifier channel amplifies the positive half of the waveform, the other channel amplifies the negative half. The loudspeaker is connected as the "bridge" between the two amplifier channels.
The act of connecting a (typically) high input impedance device in shunt across a transmission line or signal path to monitor or sample a signal.
In a multi-channel amplifier, the connection of two channels to drive a single load. The input signal is split, and then the phase of one of the signals is inverted. The non-inverted signal is sent to the left amplifier and the inverted signal is sent to the right amplifier (L+R-). The load is connected between the two outputs so it receives twice the voltage at a given input level. The resultant power is much greater than the two 4-ohm channels combined.
When a high impedance video line is paralleled to a video source, this is known as bridging.
A process where two channels of an amplifier are combined to produce one mono channel.
Increasing power by connecting a stereo power amp for use in mono, then adding a second bridged-stereo amp for the other channel. Power typically triples, but the amps must be designed to be bridged in the first place.
A term used to describe a type of automatic sequential switcher which has the ability to send a signal to two monitors (dual output) one continually sequencing and the second one able to display any one of the camera inputs on the “bridged” monitor. There are two methods of bridging a second monitor. The first is passive where the video signal is “T”ed off the incoming line and sent to the second monitor, in this case the “bridged” monitor must be unterminated. The second method is active where the video signal is regenerated by a distribution amplifier in the switcher and sent to the “bridged” monitor in which case the monitor must be terminated. The bridging switchers are not always marked as being active or passive so attention must be given to the video signal on the “bridged” monitor to be sure if the termination must be set to on or off.
Operating a stereo amplifier in mono using the bridge mode switch, which makes Channel A output the positive drive and Channel B output the negative (like push-pull). The power output of the amplifier is almost twice that of single channel operation, although internal power rails can often limit the output. Note that an amplifier's minimum load impedance is doubled when bridged.
The shunting of one signal circuit by one or more circuits usually for the purpose of deriving one or more circuit branches.
A term usually used with switchers meaning that a high impedance video line is paralleled to a source of video.
A method of connecting a high-impedance video line to a source of video information, usually through a switch.
Combining two channels of an amplifier to make one channel that's more powerful. One channel amplifies the positive portion of an audio signal and the other channel amplifies the negative portion, which are then combined at the output.
Increasing output power by connecting two 'bridgeable' stereo amplifiers together, each working on a single channel.
Combining two outputs of an amplifier to use as one, usually to a woofer. This provides the increase in power output (wattage) necessary to reproduce lower frequencies at higher volume levels.
Combining the left and right channel of an amplifier together into one higher powered channel. Amplifiers will normally state whether or not they can be bridged and what the minimum speaker impedance is that they can handle.
Combining the outputs of two amplification channels to provide one more powerful channel. Note that bridging may raise the minimum load impedance that the amplifier can safely drive.
Combining both left and right stereo channels on an automotive amplifier into one higher powered mono channel. When an amplifier is bridged, the impedance that the amplifier actually "sees" is calculated based upon the output of both stereo channels. Here is a simple formula to help define this
A term indicating that a high impedance video line is paralleled, usually through a switch, to a source of video
Combining both left and right stereo channels on an amplifier into one higher powered mono channel. When an amplifier is bridged, the impedance that each half of the amplifier actually "sees" is 1/2 of the loudspeaker's impedance.
