Introduction
Their outstanding performance of the LD Systems DDQ series is the result of a precise design and perfect
features that deserve top marks across the board.
The DDQ15 active speaker is loaded with a Faital Pro woofer and a BMS tweeter. They are driven separately by
two Hypex UCD700 700W power stage modules.
The signal is processed by a Sharc DSP programmed especially for the DDQ active systems with converters that have a
remarkable dynamic range of 127dB. It handles all protection functions, whereby the predictive peak limiter is especially
worthy of mention. With a look ahead time of 1 millisecond, it ensures absolutely distortion-free reproduction even at
maximum volume. The bass-reflex enclosure of the active speaker is made of multiplex. It is also easy to transport thanks
to the innovative Evolutive handles and the comparatively low weight.
The DDQ15 active speaker is designed for all PA applications: for mobile use, for permanent installation,
in compact systems, FOH systems or delay lines, and thanks to the integral 50° angle, it can also be used as a
stage monitor. All DDQ systems are made in Germany!
