The QSA 112A and QSA112.0 A is a compact two way powered line array speaker system. It features a B&C®
12” high excursion LF neodymium woofer and three 1” exit (1.7” voice coils) neodymium HF drivers which are coupled to three waveguide providing 100°H dispersion.
The two models have different waveguide arrangement and cabinet shape to provide 15°V dispersion for QSA112A and 5°V dispersion for QSA112.0A. Originally born as constant curvature line array, the QSA112A have the advantage to cover wide vertical angle with small cabinets, very easy set-up and uniform audience coverage. When a bigger system is required, the QSA112.0 cabinet permit to construct a J-array configuration and cover long distance with impressive SPL.
The built in power amplifier consists of an 1100w Class D for the LF and a 300w Class G for the HF. The power amp also provides 2 sets of dipswitches with factory presets to adapt the QSA 112’s EQ contour to particular system configuration and the 2nd. set of dipswitches provides 8 different delay settings. Additional features include: Gain adjustment from – 9dB to + 3 dB, four LED indictors operation status, ground lift switch, balanced XLR – F input, balanced XLR-M Loop output, auto resetting AC line circuit breaker, two Neutrik® Powercon AC connectors (one main AC in, 1 AC loop out to supply AC power to up to 3 additional QSA 112A speakers). The QSA 112A/112.0A cabinet is constructed with 18mm (3/4”) Baltic birch plywood and finished with scratch and scuff resistant black paint.
Ergonomically placed handles and mechanical hardware for suspension with a 10:1 safety factor are provided.
The QSA 112a/112.0a is an excellent choice for small to large sized venues when line array performance is desired and a fast and easy set up is required, as such is the case with a ground stacked system.
Using an optional Qube SS -210 speaker mounting pole allows one or two QSA 112A cabinets to be placed on top of a QSA 118SA subwoofer.
