SYSTEM REQUIREMENTS
System requirements – TQ-308DP, TQ-310DP and TQ-315DP
These products are two-way self-powered loudspeaker systems. They comprise two independent
amplifier channels: one channel to power the low frequency driver (LF) plus another channel to
power the high frequency (HF) driver; plus an active crossover to split the signal and feed it to the
appropriate amplifier and driver section. Additional features such as limiting, digital time
alignment and driver EQ are carried out in the on board DSP. These products do not require the
use of external amplifiers or crossover/limiters.
Additional units may be daisy-chained together simply by linking the signal connections through
the input / link XLR connectors. In this way exact coverage of an event or permanent installation
may be achieved using a number of digitally powered loudspeakers. It is however necessary to
route individual power cords to each enclosure as it is not possible to daisy-chain AC connections
through the power connectors.
System requirements – TQ-445DP
The TQ-445DP is a three-way self-powered loudspeaker system. It comprises two independent
amplifier channels: one channel to power the low frequency driver (LF) plus another channel to
power the high frequency midrange (MF) and high frequency (HF) together; plus a frequency
dividing network to split the signal and feed it to the appropriate driver section. Additional
features such as limiting, digital time alignment and driver EQ are carried out in the on board DSP.
The TQ-445DP does not require the use of external amplifiers or crossover/limiters.
Additional units may be daisy-chained together as above to achieve exact coverage of an event or
permanent installation using a number of digitally powered loudspeakers.
System requirements – TQ-425DP and TQ-115DP
These products are self-powered subwoofer systems designed to accompany QLight™ series self-
powered loudspeakers. The TQ-425DP comprises two independent amplifier channels: one
channel to power each low frequency driver. The TQ-115DP uses one amplifier channel to power
the single drive unit.
Additional units may be daisy-chained together as above to achieve exact coverage of an event or
permanent installation using a number of digitally powered loudspeakers.
