[. . . ] 7 Figure 1 8 Hookup with Active Speakers If, on the other hand, you are using passive (non-powered) monitor speakers that require an external amplifier, hook the two outputs of the subwoofer up to the inputs of the stereo monitor amplifier. Typically this would also be an XLR connector, but if need be, you could use the other connections providing the amplifier will accept them at the amp. Connect the power amplifier to the speakers as you normally would. Do not attempt to hook the speaker output of the monitor amplifier to the input of the subwoofer, you run the risk of damaging the equipment. Rotate the subwoofer's gain control counterclockwise and set the low-pass filter control to the 80Hz position. Power up the subwoofer prior to the other speakers (shut down in reverse order); note that the power light is illuminated. Play back some music and turn the console output up to a moderate listening volume. At this point, the bass should sound quiet. Then, slowly rotate the gain control until the bass seems appropriate for the mix. If you are used to using near-field monitors with limited bass response, the difference will be quite startling. Once you have the system up and running, go to the section on subwoofer placement and adjustment (Section 7 --Subwoofer Placement and Setup and Section 8 -- Bass Management Theory) and learn some of the finer points of subwoofer application. Hooking Up Your Subwoofer for 5. 1 Surround This is a bit more complicated than a stereo hookup since there are now six speakers involved -- as well as something called Bass Management (see Section 8 -- If you are using active (powered) speakers, simply use an XLR 1/4" Phono or RCA to connect the output of the subwoofer directly to the input of the speaker. The output marked "Left" should go to your left speaker, and the output marked "Right" should go to your right speaker Hookup with Passive Speakers 9 10 Bass Management Theory). Note from the diagram that for professional use a separate 6- channel level control box is required between the mix-down deck and the monitor speakers. This is because few small format mixing consoles have provisions to switch and level-manage a 6-channel audio signal. The simplest and perhaps best way to accomplish this is to use an external, 5. 1 level controller. It is placed between the outputs of the mix-down deck and the monitor speakers, allowing it to control the playback level while the mix-down deck receives full-level recording signal. Another option is to use a consumer, home-theater receiver in place of a professional level controller. Many of the current generation receivers have separate analog inputs that can be used for directly monitoring your mix from the console. If you are using unpowered, full-range speakers, then you can utilize the onboard power amps in the receiver itself to power them. If, on the other hand, you are using selfpowered speakers for the full-range monitors, be sure to pick out a receiver that has preamp line-level outputs in addition to speaker-level outputs. Be aware that some inexpensive home theatre receivers disable bass management for the analog line inputs. phone, then setting up the room can be fairly painless. However, it can also be done with a generic SPL meter, or even your own ears, once you know what to listen for.
