This Auditorium Sound System comes with two SD4 Ceiling Speaker Arrrays. The SD Speaker employs (4 smaller 6.5") very fast transient response aluminum-woofer drivers that are very powerful and stable. Working in unison these drivers produce clean powerful dynamic sound. When designing the SD the goal was to have the single most import feature at the forefront, good transient response ("dynamic contrast"). A transient is a sound of short duration, and good transient response can only be achieved if the speaker can deliver its output quickly and cleanly without smearing the original sound, and be completely soundless immediately after. Transients contain the essentials of sound reproduction they provide the sharp pop from a snare drum, the cutting edge of digital sound, the dynamics of the human voice. Larger 2-way cabinet loudspeaker systems offer relatively slow transient response, and the small high-frequency horn tends to beam a narrow, blaring sound at the listener—end result, muddy sound. By replacing larger speakers with four 6 or 8" drivers we increased the driver surface area while creating more punch and a tight, more focused low-end.
The QSC AD-C81Tw is part of the AcousticDesign Series of installation loudspeaker products from QSC. The AD-C81Tw ceiling mount subwoofer system is designed to supplement audio systems with low-frequency extension, the new AD-C81Tw is acoustically matched to the entire AD Series. Rated for 100 watts continuous power handling and able to take up to 400 watt peaks, the AD-C81Tw is a great compliment to any of the ceiling mount or surface mount speaker.
The new ROLLS RM64 Four Zone Mixer combines two paging microphones with up to four line level source inputs. Each input is switch selected to output to any combination of four zone outputs. The outputs are all balanced XLR connectors, and a 1/4" Remote Volume jack provides each zone with the means for external volume control.
The QSC ISA500Ti is part of the ISA Installed System Amplifiers are designed to meet the needs of sound system designers
and contractors worldwide. Three models feature isolated 25, 70, and 100 volt outputs for distributed sound systems, while four low impedance models are rated for 2 ohm operation. The ISA 1350 drives 70 volt lines directly with 1500 watts per channel. Versatile loading options and a comprehensive set of features make the ISA Series a rugged, cost-effective power solution for any permanently installed sound system.
