User manual PIONEER XR-Q150

[. . . ] As a member of the DCS Digital Cinema Speaker Series, the XR-Q150 is a 3-way, selectable bi or tri-amplified screen channel loudspeaker system comprised of two main units--the MH-1075 high-frequency system and the LF-4315 low-frequency system. [. . . ] The MH-1075 includes a driver protection network and a passive crossover for bi-amp operation. Power limiter circuitry protects the high-frequency driver from overpowering. The MH-1075 provides extended frequency coverage for the critical midrange band. The MH-1075 components come pre-assembled to reduce field assembly time. Three bolts are all that are required to secure the MH-1075 to the top of the LF-4315 enclosure.
