QA 108A Active Line Array Biamp powered line array system featuring Class D amplifiers with a switch mode power supply, delivering 400W RMS LF and 100W RMS HF. A built-in DSP provides crossover, equalization and component protection. The DSP has a 4 position switch to set 4 different EQ curves, with each selection dependent on the number of the cabinets used: 1, 2, 4, 6 up to 12 speakers. A rotary potentiometer adjusts volume/gain level. A switchable HP filter can be engaged when the QA 108A cabinets are used in combination with the QA118SA active subwoofers. The control panel features:
QA 108 Line Array Two way passive line array system featuring a high quality passive crossover network with a built-in soft thermal protection circuit with an auto-reset feature for the LF woofer and the HF PDT.

3 LED indicators for the power amps operation status (Power-On, Peak and Protection/Limiter), a balanced XLRF input connector and a balanced XLR-M loop output connector to daisy chain the signal input to additional QA108A speakers. Two Neutrik Powercon AC connectors (1 mainAC in, 1AC loop out to supply AC power to up to 3 QA108A). The QA108A compact enclosures have a trapezoidal shape with an angle of 10V°, and are constructed with 12 mm. (1/2") Baltic birch plywood and finished with scratch and scuff resistant black paint. A heavy duty metal grille with cloth protect the drivers from dust and moisture. The cabinets are provided with two integrated fly points for suspension allowing settings in 1° steps from 0° to 10°.
Biamp or Full range passive operation mode is user selectable from the rear panel that is equipped with Neutrik Speakon NL-4MDV connectors IN & LINK OUT. The optional QUBE SP27 is a Digital Signal Processing Controller programmed to optimize the performance of the total system and is recommended when using multiple QA108 line array cabinets.
