11.) Power input, Fuse Sled and voltage SwitchConnect the supplied standard IEC AC power cable here. Be sure to confirm and install the properly rated fusewhen replacing the fuse or changing the operation voltage. Slide to change the operation voltage from 115 to230 Volts.12.) PowerSwitches on the DSW-500NNote: The power led is normally green. When change to red is the limiter protection activated.NOTES ABOUT HUMWhile the DSW-500N has designed to minimize the possibility of hum in the subwoofer or full range system, itstill possible that a hum will occur in rare circumstances. Its safety grounding can create a path for smallamounts of 50 to 60 Hz (depending of the frequencies in the power jackets) energy to travel trough the linelevelaudio system. To reduce hum, all connections can be connected to a single grounded outlet.Rated Power Output:Signal to Noise Ratio:Input Impedance:Sweep Control:Subsonic Filters:Other Controls:Dimensions:Power Requirements:Weight:SPECIFICATIONS:300 watts RMS into 8 ohms @ 0.1% THD500 watts RMS into 4 ohms @ 1.0% THD90 dB A-weighted12K ohms30 – 200 Hz, 24 dB per octaveOFF, 20, 35, 50 HzPhase 0° (NOR) or 180° (REV), LPF-FilterHPF-Filter, Stereo-Mono- and Bypass switch304 mm W x 304 mm H x 135 mm D115/230 VAC, 50/60 Hz, 800 WFuse 8 AT, 250V (115VAC)Fuse 4AT, 250V (230VAC)8, 9 kgImportant Safety InstructionsTo reduce the risk of electric shock, do not remove cover.
