The Bag End ID-12PRO or Infrasub 12 PRO is a self powered professional subwoofer system employing bass management, hi pass filtered outputs, a sealed front firing 12" cone loudspeaker, and the INFRA dual integrator driving a 400 watt power amplifier providing a flat acoustical response down to 8 Hertz. Six inputs allow the combining of all the bass information on 5.1 surround programs and 2 level controls and a 10dB attenuator provide relative adjustment of the bass information from the 5 full range channels and the dedicated low frequency effect channel. 5 hi pass line level filtered outputs are provided for the upper range loudspeakers and a line level INFRA output is provided for additional INFRA bass speakers. Internally set Dynamic Filter protection maintains undistorted audio reproduction under accidental overload conditions. A remote indicator module is provided and may be placed in a convenient visible location to indicate the dynamic filter protection threshold has been reached.
