JRX 118SP

The JRX118SP is an 18 inch directradiating powered 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 1/4 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.

The JRX118SP is designed to supplement and extend the low frequency 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.

Detalles:
  • The rugged enclosure is constructed from 19 mm (3/4 in) MDF (Medium Density Fiberboard) 
using advanced adhesives and mechanical fastener technology for durability and improved
low frequency 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 operation in 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, highpassed outputs
to feed powered satellite speakers or an external amplifier for passive satellites.
  • A speaker-level, 1/4" 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.
