Product information "JBL JRX-118 SP"
performance of full-range systems in live sound and music playback applications.
It is an excellent choice for use with powered full-range speakers
or in systems using powered mixers.
Features
The rugged enclosure is constructed from 19 mm (¾ in) MDF (Medium Density Fiberboard)using advanced adhesives and mechanical fastener technology for durability and improved lowfrequency performance. The enclosure is covered in black carpet.Heavy duty, all steel handles are used.A top mounted, cast aluminum 35 mm pole mount receptacle can receive an optional SS3BK pole to facilitate use of the JRX118SP as a base for a mid-high speaker cabinet.Built-in 500 watt (peak), 300 watt (continuous) amplifier. Controls, connectors, and indicators are clearly labeled with large, highcontrast graphics for easy operationin poorly lit environments.
Integral, preset limiter prevents clipping distortion. An LED illuminates to indicate that limiting is taking place.Line-level stereo inputs are summed before being sent to the subwoofer’s internal amplifier. This feature allows the JRX118SP to operate in stereo systems using a single subwoofer.An integral crossover also provides balanced, line-level, stereo, highpassedoutputs to feed powered satellite speakers or an external amplifier for passive satellites.
A speaker-level, ¼" TS phone jack is provided. This input is useful in applications, such as those employing powered mixers, in which it is more practical to bring a full-range, speaker-level signal to the subwoofer amplifier. The JRX118SP is an 18 inch directradiatingpowered subwoofer. A built-in 500 watt (peak) amplifier accepts stereo or mono line level
inputs via balanced, XLR connectors as well as single channel speaker level input via a ¼ inch phone jack. Integral signal processing includes a stereo crossover and limiting for the
internal amplifier. A pair of XLR output connectors may be used to pass the input signals to another system or to send a high-passed, line-level stereo signal to a pair of powered,
full-range speakers.
