LINE ARRAY SYSTEM
QA 118SA Active Subwoofer The QA118Sa is the matching active subwoofer for QA108a two way line array cabinets, although it can be utilized to provide additional LF SPL with any sound system. The QA118Sa is a compact, high power subwoofer system loaded with a B&C18” woofer with a 4” voice coil in a bass reflex design cabinet and is powered by an internal 1200W Class D power amplifier with a switch mode power supply. With an extended frequency response down to 33Hz, the QA118Sa delivers 137 dB SPL. Only the best quality European electronic parts are used in the power amp module circuitry to provide superb specifications, reliability and longevity. The Control Panel features stereo left & right channel XLR inputs and stereo left & right XLR link outputs, volume control, 0°180° phase reversal switch, three LED indicators for the operation / power status (Power On, Overload, Protect). The DSP controller provides 6 different equalization presets and 6 different delay settings. Two Neutrik Powercon AC connectors (one mainAC in and oneAC loop out to supplyAC power to an additional QA118Sa or to power two QA108Aline arrays). The QA118a cabinet is constructed with 18mm (3/4”) Baltic birch plywood and finished with
scratch and scuff resistant black paint. Ergonomically placed integrated handles provide for easy handling / lifting / transporting. The QA118SA also features a 20mm female top mount flange for the optional satellite pole mount (model. SS108.) With use of the optional QUBE SS108 speaker mounting pole, one or two QA108A two way line array cabinets can be placed on top of a QA118SA subwoofer, with the SS 108's adjustable angle pole providing aiming flexibility. The cabinets built-in side mounted hardware allows to securely lock the QA108 cabinets together when stacking them.
QA 118S Passive Subwoofer The QA118S is the companion subwoofer for QA108 passive two-way line array cabinets. The QA118S compact, high power, subwoofer system is loaded with a B&C 18” woofer with a 4” voice coil in a Bass-Reflex designed cabinet capable of handling 1400 watts at 4 ohms. With an extended frequency response down to 36Hz, the QA118S delivers 138 dB SPL. The cabinet is constructed with 13 ply, 18 mm. (3/4”) Baltic birch plywood and is finished with a
durable scratch and scuff resistant black paint. The cabinet also features integrated ergonomically placed carrying handles and a built in top mount flange for a optional speaker mounting pole for two way satellite speakers. An optional 4 wheel trolley (WT118S) with locking wheels holds 2 x QA118S/Sa subs, and allows them to be easily transported for touring and mobile applications.
