4. sit down to enjoy your new subwoofer you need to perform one simple Phasing Test This test insures optimum sound in the critical bass frequencies where your subwoofer and satellite speakers overlap Play familiar CD LP or tape with steady consistent bass Listen carefully to the mid bass 70 100 Hz region the part of the spectrum where electric or string basses and drums are found Then move the PHASE switch on the SUBWOOFER s back panel from either up down to the opposite position Now listen to the same musical passage concentrating on the mid bass region If you hear less bass the original connections were correct If you hear more bass the new connections are correct If you have two subwoofers perform one test for each subwoofer When you perform each test make sure the other subwoofer is not operating by either unplugging its input cable or its power cord Another method of setting phase uses a pink noise source and a spectrum analyzer If you have these place the microphone at the main listening position and look at its display in the mid bass region of 70 100 Hz The wiring switch position showing the most output in that region has the correct phase You need to perform this test because when satellite speakers are located separate from a subwoofer each speaker is at a different distance from your ear In some cases the difference will be just enough so that the output from the subwoofer arrives out o

11. f phase with the output of the satellites When this happens that critical mid bass is actually cancelled You should re do this test any time you move your speakers If you want to experiment further you can move the satellite speakers either towards or away from your listening position making changes in small increments This will focus the system s sound to its optimum When you hear the best balance between stereo image localization and maximum impact and output in the mid bass you have the ideal location 6 USEOFTHE LOW PASS FILTER CONTROL The back panel control LOW PASS FILTER sets the upper rolloff point of the subwoofer eliminating mid bass and midrange that are being reproduced by your satellite speakers The control is a means of fine tuning the transition between your subwoofer and satellite speakers and it provides a rolloff of 12 dB octave up to 125 Hz where the filter shifts to 36 dB octave In most systems including M amp K satellites 85 Hz gives the best blend If you don t want to experiment set the control at 85 Hz The goal is to get a balanced acoustic output in your room This is not necessarily the same as flat electrical output Rooms typically reinforce bass frequencies around 100 Hz so by leaving an electrical gap you may actually get a smooth acoustical response where it matters in the room Think of this control as a mid bass fine tuning adjustment that you set to achieve the best transition between the sate
