10Setting up the RESOLV 120a® ®CONFIGURING YOUR SPEAKER SYSTEMBefore you start plugging in cables, you should take a minute and decide how you want to interface your newsubwoofer. There are several ways you can interface the RESOLV 120a and two specific categories should be considered.First, Stereo vs Mono operation, and second, whether High (powered) or Low (line) level inputs and outputs will be used.®®Common Sub OperationIn most cases, a common sub ( mono) bass operation isdesired. This is true for several reasons, but mostly becauselow frequencies produced by a subwoofer tend to be non-directional. Since low frequency sound waves take so muchspace to develop, you can’t tell if the sub-bass is comingfrom the left or right side,unless of course you’re in a verylarge room. Because of this phenomenon, just about allsub-bass material is mixed in mono.Stereo Sub OperationTwo RESOLV 120a’s can be used in stereo in larger controlrooms for increased low end. In addition, two RESOLV120a’s can be used in stereo, even in smaller control rooms,to help minimize standing waves. By using two subwoof-ers at lower power, you can achieve a more even responsethroughout the room.Placing the RESOLV 120aBecause the low frequencies reproduced by the RESOLV120a are non-directional, you can position the unit almostanywhere. It is however, a good idea to keep the RESOLV120a away from corners. Ideally the RESOLV 120a shouldbe positioned in the middle, and up close to, the wall youare facing in the mixing position.RESOLV 120a Control PanelThe RESOLV 120a’s control panel provides the connections and user interface to the RESOLV 120a’s internal electroniccrossover and power amplifier section. The internal amplifier is a 120 Watt power amplifier capable of producing incred-ible bass output. The RESOLV 120a employs an electronic crossover that adjusts the high frequency cutoff point forthe subwoofer, and also a high-pass output for your satellite speakers. You will achieve a tremendous benefit in soundquality by running your satellites speakers from the RESOLV 120a’s High-Pass outputs. The reason for this is that whenyour satellite speaker receives the filtered output from the RESOLV 120a, it will no longer be looking at the frequenciesbelow the crossover point. Let’s say your satellite speaker has a natural frequency roll-off at 70 Hz, and you are sendingfull range signal (as low as 20Hz) to the satellite amplifier and speaker. Even though the speaker can only reproduce70Hz and up, the amplifier is still outputting 20-70Hz, which is wasted power and ultimately turns into heat. By using theRESOLV 120a’s High-Pass output, the satellite amplifier and speaker never see the frequencies lower than what’s set bythe Sweep frequency. This means you’ll have more power dedicated to the frequencies you want the satellites to repro-duce, resulting in a much cleaner sound with more headroom.Operating the RESOLV 120aENGLISH
