patch bay การใช้

• The VF primary patch bay provides patching, monitoring, and testing for all VF circuits.
• Its product range includes powerCON connectors, patch bays, BNC connectors and special connectors for industrial applications.
• Instead of these circuits going directly to the dimmer they are connected to a " patch bay ".
• If a patch bay is wired to full-normal, then it includes break contacts in both rows of jacks.
• On some amps with a number of input and output jacks, the jacks may be consolidated in a patch bay.
• A patch bay usually sits next to the dimmers enabling the dimmers to be connected to specific circuits via a patch cable.
• The patch bay is numbered, so that the engineer can note which microphone or instrument is plugged into each numbered connection.
• The patch bay may also enable many circuits to be connected to one dimmer and even series connection for low-voltage lamps.
• However, emulating or exceeding the capabilities of audio and / or video patch bays requires specialized devices like routing switches and crossbar switches.
• Patch bays may be half-normal ( usually bottom ) or full-normal, " normal " indicating that the top and bottom jacks are connected internally.
• Within a technical control facility, a single direct transmission circuit, between positions in a testboard or patch bay, which circuit facilitates testing or patching between the respective positions.
• They are represented on the front panel of many synthesizers as knobs, but often a patch bay allows the input or output of the related CV to synchronize multiple modules together.
• The patch bay is a flat panel of audio connectors where XLR cables ( often both " male " and " female " ) and 1 / 4 inch jacks can be plugged in.
• The assigned connections between the circuits ( either at the patch bay or in the form of individual cables ) and the dimmers is known as the "'mains "'or "'hard patch " '.
• Patch cords can be as short as 3 inches ( c . 8 cm ), to connect stacked components or route signals through a patch bay, or as long as twenty feet ( c . 6 m ) or more in length for snake cables.
• Music venues, concert halls, and recording studios also use a thicker, hose-like cord called a snake cable ( or a " snake " ), which consists of a bundle of many individual cables with patch bays at either end so that audio gear can be connected.
• It was also much easier to examine than the tangle of patch cords used to interconnect other modular systems of the day, such as the Moog modular synthesizer and was many times smaller than the cumbersome Moog patch bays, which used patch cord leads capped with 1 / 4-inch'phone'jacks.
• It is an expanded Voyager that includes, in addition to the original Voyager features, a larger 61-note keyboard, a ribbon controller, an additional LFO / modulation bus, and most notably, a patch bay on the far left of the instrument & mdash; providing a similar modular functionality to the VX-series products.
• A system comprised a Mix Controller ( roughly the size of a kitchen table ), the ( analog ) Audio Mainframe, a single multi-pair control cable between them, the Support Computer ( with color monitor ) connected to the Mix Controller via RS-232, and an external patch bay with up to 8 Elco multi-pair cables to the Audio Mainframe.
• A "'patch panel "', "'patch bay "', "'patch field "'or "'jack field "'is a device or unit featuring a number of jacks, usually of the same or similar type, for the use of connecting and routing circuits for monitoring, interconnecting, and testing circuits in a convenient, flexible manner.
