Introduction Thank you for choosing the M-Audio SBX10 active subwoofer. SBX10 has been designed to integrate seamlessly with the M-Audio BX, CX, and DSM lines of active studio monitors, extending the low-frequency response of the total monitoring system down to 20Hz. Moreover, the versatile design of SBX10 allows it to work well with any combination of active studio monitors in a 2-channel stereo or multichannel surround environment.

Variable Crossover You can use SBX10 in a variety of monitoring contexts, from 2-channel to multichannel (e.g., 5.1, 7.1) systems, and as an accompaniment to practically any direct-field monitors. To this end, we have provided a versatile yet efficient way to tailor the response of the subwoofer to work well in any typical monitoring system.
4. Phase Select Because low-frequency signals have long wavelengths compared to the dimensions of most rooms, subwoofers often tend to cause room modes and cancellations that can be quite dramatic. For this reason, we have included a phase inversion switch, which causes a 180° phase shift in the subwoofer's output. This allows you a greater degree of freedom in choosing where to locate the SBX10 unit (and consequently, the crossover frequency phase alignment) in your monitoring environment.
9. XLR Outputs These jacks accept XLR connections with either balanced or unbalanced wiring, and are used for sending audio signal to your stereo direct-field monitors. The wiring of an XLR connector used with the XLR Outputs should be the same as what is listed for the XLR Inputs (7). 10. TRS Outputs These jacks accept 1/4” connections with either balanced or unbalanced wiring, and are used for sending signal to your stereo direct-field monitors.
Enclosure (not pictured) Like the other components, the enclosure has an important role in shaping the overall sonic response. In order to provide more stable performance, the SBX10 subwoofer employs a special high acoustic efficiency medium density fiberboard (MDF) and unique interior reinforcement bracing designed to reduce sonic coloration and absorb vibration and impact generated as the subwoofer reproduces high SPL signals and transients.
Setting Up the SBX10 Subwoofer Connecting the Power AC Voltage Select: Since the SBX10 subwoofer contains its own amplifier, it must be connected to a power outlet using the detachable AC cable provided. Note that the AC Voltage Select switch (located below the IEC socket for the mains power cord) is user-selectable for 100-120V~50/60 Hz or 220-240V~50/60Hz operation. Before you do anything, make sure the AC Voltage Select switch is set to the appropriate position for your location.
Multichannel (e.g., 5.1, 7.1-channel surround) Operation: If you're mixing or monitoring a multichannel source, you undoubtedly have an external bass management system and/or you may be sending the LFE (low-frequency effects) channel directly to the subwoofer with no additional signal redirection. In this scenario, you can route your subwoofer audio signal to either the left or right input on the SBX10 subwoofer.
Phase Select (4) As we mentioned before, this switch inverts the signal (the phase angle from 0° to 180°) that goes to the subwoofer amplifier. The Phase Select function does not affect the signal going to your direct-field monitors. You can select the appropriate position of this switch by listening to the way the sound from the SBX10 subwoofer blends with the rest of your system.
Placing the SBX10 Subwoofer The "location location location" cliché doesn't only apply to the real estate market. It is equally (if not more) applicable to the subject of loudspeakers and room acoustics. As you can imagine, where you place the SBX10 subwoofer in your room can have a huge impact on how it will sound. In fact, any well-designed, powerful subwoofer can sound like a complete dud in your monitoring setup if you have placed it poorly.
