It is a service part for restoring the mid\/high-frequency section of an existing DCS cinema loudspeaker (MiT order code A015157-001). Use it to replace a failed coaxial driver with the factory-specified unit.\u003c\/p\u003e\u003ch2\u003eHow does the DCS SP-000157-00 work?\u003c\/h2\u003e\u003cp\u003eA coaxial driver combines two sections on one axis, so the larger section and the smaller section radiate from the same point. On this BMS driver the 4-inch and 1.75-inch sections are each rated 8 ohms and are fed as separate bands. Because each section has its own input, the driver works in bi-amplified or passive configurations as set by the loudspeaker it belongs to. A technician removes the failed driver, mounts the new one to the same horn or baffle, reconnects both sections with correct polarity and verifies output before returning the speaker to service. DCS uses compression-driver mid\/high sections on screen channels such as the \u003ca href=\"https:\/\/creationnetworks.net\/products\/qsc-bi-or-tri-amp-3-way-1x15-consists-of-lf-4115-and-mh-1075c-components-sc-413c\"\u003eDCS SC-413C\u003c\/a\u003e, \u003ca href=\"https:\/\/creationnetworks.net\/products\/qsc-bi-or-tri-amp-3-way-2x15-consists-of-lf-4215-and-mh-1075c-components-sc-423c\"\u003eDCS SC-423C\u003c\/a\u003e and \u003ca href=\"https:\/\/creationnetworks.net\/products\/qsc-high-power-bi-or-tri-amp-3-way-4x15-consists-of-2-x-lf-4215-and-mh-1075c-components-sc-443c\"\u003eDCS SC-443C\u003c\/a\u003e, but the exact driver depends on model and production run.
