User manual M-AUDIO SBX

[. . . ] This significantly improves fidelity because the sub and mains aren't tripping over each other to reproduce the same frequency--and each component only has to reproduce frequencies to which it is ideally suited. Your SBX also features auto-muting circuitry that automatically turns the subwoofer on when it senses a program signal while turning it off to conserve power when no signal is present. Various controls also allow you to adjust the performance of the SBX in conjunction with the rest of your system. While the SBX is easy to operate, we suggest that you take a few minutes to read the rest of this manual in order to derive optimal audio quality from your new subwoofer. Enjoy! 2 In order to avoid risk of damage and insure optimum performance from your SBX Subwoofer, please take time to read this manual before you proceed to unpack and install it. First Things First In the Box Carefully remove the SBX from the carton, paying extra attention to avoid touching or damaging the speaker cone. [. . . ] Output section: This section provides three balanced XLR outputs labeled "Extra Sub" and "L" & "R. " The Extra Sub output gives you throughput directly from the inputs for the purpose of connecting an additional subwoofer. The L and R outputs are to be used for connecting Satellite speakers (your left and right mains) when using the Bass Management System. Fuse holder: This fuse holder allows the replacement of a fuse for the purpose of circuit protection. Power On/Off switch: Switching to "On" will power the SBX subwoofer. Manufacturer's Label: This section gives the model number and manufacturer information, including important power requirement information. Voltage-Select Switch: Provides 2 selections - 115VAC (120VAC) and 230VAC, and should be set to match the "house current" (receptacle) voltage of the country/location in which the speaker is used. The 115V (120V) setting is correct for the USA and the 230V setting correct for most of the UK and Europe. Rear Panel Features: 4 5 Most applications will utilize the SBX's internal Stereo Bass Management System to realize maximum benefit. There are, however, two possible operational modes that you may use when connecting your SBX and your Mains, or "Satellite" stereo speakers, i. e. , 1) using the SBX with bass management and 2) using the SBX without bass management. Connecting the SBX and Your Main Speakers Using the SBX with Stereo Bass Management To take advantage of the SBX'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 SBX (#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 SBX to the inputs on the left and right satellites. 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. 6 Using the SBX without Stereo Bass Management You may wish to use the SBX with an existing external bass management system, or with bass management defeated on the SBX. 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 through to the outputs. In this setup, you will want to set the Subwoofer LPF control knob to the desired cutoff frequency for the SBX. 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 SBX 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 InputR connections on the SBX. In this setup, you will want to set the Subwoofer LPF control knob to the desired cutoff frequency for the SBX. Once again, the Satellites HPF control knob is not operational with the HPF Bypass switch set to "On. " 7 Connecting an Additional Subwoofer If you have a large monitoring environment requiring greater subwoofer sound pressure, you can connect as many SBX cabinets as desired in a daisy chain. These combined controls make it possible to optimally match the low bass frequencies from the subwoofer to your unique combination of satellite speakers, room characteristics and subwoofer position. Because of these variables, there is no single recipe for obtaining the best audio results. While you can certainly apply sound meters and other analysis equipment in establishing the right settings, most people use their ears and a few familiar recordings to determine the best settings. Min Max 0° 180° 50Hz 180Hz 50Hz 180Hz Setting the Level Control Use the Level control (#2) to adjust the volume of the subwoofer to properly match that of the satellite speakers. We suggest starting with this knob in the 12 o'clock position. Note: Placement has a great deal to do with how the Level knob is set. [. . . ] If the fuse needs replacing, it is critical to use only a fuse with an identical rating. Support The M-Audio. com website (www. m-audio. com) contains the latest troubleshooting information.
