User manual ELECTRO-VOICE QRX BROCHURE

[. . . ] Introducing the totally twisted Electro-Voice QRx-Series loudspeakers ® ® TM TM More than a club box. [. . . ] If you horizontally mount an QRx-112 cabinet tight against a ceiling, for example, you can rotate the horn so the 35° down part of the pattern puts more coverage into the audience seating and lessinto the ceiling. A new DH-7 compression driver with a big 3-inch voice coil supplies optimized performance: more sound pressure level with less distortion. A newly designed motor structure powers the voice coil and helps cut the weight of the driver. This eliminates the need for extra support inside the cabinet-- which is why you can have your asymmetrical horn and rotate it, too. RMD Ring Mode Decoupling is used in all QRx-Series loudspeakers. RMD technology suppresses the acoustic and mechanical resonances that ring beyond the desired sound and color loudspeaker performance. With RMD, QRx-Series loudspeakers deliver spectacularly clear vocals and constant fidelity at all SPLs. ® External passive/bi-amp switches eliminate the much-cursed process of digging behind the connector panel to rewire a speaker for bi-amp operation--great for rental companies. And all QRx cabinets include integrated protection circuits just in case some FOH engineer gets unhinged. [. . . ] All of the QRx-Series cabinets have ultracompact dimensions to save transport volume, allow easy handling, and fit into the small spaces of problem installations. ©2001 Telex Communications, Inc.
