Loudspeaker Management System


The LMS-D4 is designed for use with the company's loudspeakers in live sound and fixed installation. Designed to provide tailored equalization and crossover functions specific to QLight, HiLight, TCS Series, and TFM Series loudspeaker systems, the LMS-D4 ships with factory-set programs for front-of-house and floor monitor applications. The LMS-D4 forms a sound reinforcement system when partnered with TQ-310 or TQ-315 loudspeakers. The main features include: FIR and IIR filters; high-performance limiters; gain, polarity, and bass trim; up to 42 ms of delay per output for precise alignment of drivers and external subwoofers; and a 100V to 240 VAC autoswitching power supply.

The Advantage loudspeakers are a combination of round shapes for in-ceiling applications and rectangular for use in walls that use patented design techniques. Among the features of Advantage loudspeakers is Twist and Tilt, a patented design found on all round in-ceiling Advantage models that is essentially two models in one: a standard flushmount as well as a directional speaker. The Advantage rectangular in-wall models use a design technique for reducing unwanted wall vibrations for better, clearer sound — the Iso-Mount suspension is a thermopolymer isolation gasket that physically separates the baffle from the frame to effectively absorb resonances that would normally be transmitted to the wall.

Coaxial Enclosures

Quad Industrial

The QPS series targets the architectural sound reinforcement market with a range of compact point-source coaxial enclosures. The lineup includes the 8-inch QPS8, the 10-inch QPS10, the 12-inch QPS12, and the 15-inch QPS15 versions, along with the 8-inch QPS8M and the 15-inch QPS15M floor monitors, built into 60-degree angled enclosures for close monitoring in confined spaces. Low-profile 12-inch and 15-inch subwoofers (designed as the QPSB12 and QPSB15, respectively) complete the series. Thought was given to targeting niche markets in its application; for example, the compact 8-inch floor monitor is for speech applications in ballrooms, banquet halls, and auditoriums, whereas the 600W 15-inch sub measures less than 10 inches high and is thus for concealing under the low stages commonly found in small auditoriums and lecture theaters.
