Within the SP-8S package you should find: · This manual · The SP-8S Subwoofer · One (1) standard AC Power cable Correct Power Operation Since the SP-8S contains its own amplifier, it must be connected to a power outlet using the detachable AC cable provided. Before connecting power, please make sure that the Voltage-Select Switch, located on the the speakers rear panel is set to the appropriate position, as described in the rear-panel features list appearing earlier in this manual. Note: - WARNING!- Use of improper voltage/ selector switch combinations may result in hazardous conditions and/or damage to speaker components not covered by speaker warranty. Positioning the Subwoofer in the Studio In theory, the best position for the SP-8S subwoofer is midway between the satellite speakers, with its front facing forward and in the same plane as the fronts of the satellite speakers. However, due to the fact that low bass frequencies are somewhat non-directional, you may locate the SP-8S quite far from this position without any detrimental effect on the sound reproduction. Each room is different in acoustic properties, so please feel free to experiment with placement. Different positions of the SP-8S in relation to walls will affect its efficiency, as well as the room's overall influence on the frequency response. You can compensate for this by readjusting the filter settings (see section, "Setting the Subwoofer LPF and the Satellites HPF"). Connecting the SP-8S and Your Main Speakers Most applications will utilize the SP-8S's internal Stereo Bass Management System to realize maximum benefit. There are, however, two possible operational modes that you may use when connecting your SP-8S and your Mains, or "Satellite" stereo speakers, i. e. , 1) using the SP-8S with bass management and 2) using the SP-8S without bass management. 5 Using the SP-8S with Stereo Bass Management To take advantage of the SP-8S's internal Stereo Bass Management System, your main monitors become satellites of the subwoofer. Connect the left and right main or control room outputs of your mixer, sound card, or other audio source to the Input-L and Input-R jacks of the SP-8S (#6) respectively. (You may use either the XLR or TRS inputs, depending upon your cabling needs. ) Then, connect Output-L and Output-R (#9) XLR jacks on the SP-8S to the inputs on the left and right satellites Mixer, Sound Card, or other Audio Source audio outs Input L Input Input R Input SP-8S Output R Output L Left Satellite . Once you have completed this setup, you must set the Subwoofer LPF control knob and the Satellites HPF control knob for your particular needs. Please see the section, "Optimizing the Rear Panel Settings" for information on how to do this. Also note that the HPF Bypass switch is set to "Off" in this scenario. Using the SP-8S without Stereo Bass Management You may wish to use the SP-8S with an existing external bass management system, or with bass management defeated on the SP-8S. See section, "Setting the HPF Bypass Switch" for more information on defeating bass management. With bass management defeated, you may still use the speaker setup illustrated above. With the HPF Bypass switch set to "On, " the L & R XLR Outputs will operate in a "Thru" mode, passing the original signal at the Input section directly 6 Right Satellite through to the outputs. In this setup, you will want to set the Subwoofer LPF control knob to the desired cutoff frequency for the SP-8S. The Satellites HPF control knob is not operational with the HPF Bypass switch set to "On. " If you are using an external bass management device, or if you have an auxiliary or subwoofer output send, you may want to connect this directly to the SP-8S while connecting your main L & R outputs directly to your "Mains, " or stereo L & R speakers. In this instance, you may use either the Input-L or Input-R connections on the SP-8S. External Bass Management Left Satellite Subwoofer Right Satellite Input L or R Input Input SP-8S Right Satellite 7 Left Satellite In this setup, you will want to set the Subwoofer LPF control knob to the desired cutoff frequency for the SP-8S. Once again, the Satellites HPF control knob is not operational with the HPF Bypass switch set to "On. " Connecting an Additional Subwoofer If you have a large monitoring environment requiring greater subwoofer sound pressure, you can connect as many SP-8S cabinets as desired in a daisy chain. [. . . ] To ensure that this is not the case, perform the following test at installation of the SP-8S. Set up the equipment for playing a record. Place the stylus on a non-rotating record (disconnect the turntable power cord if necessary). Tap the turntable while gradually increasing the volume of your audio system. [. . . ]
