Y our Studiophile SBX The SBX is a high-quality subwoofer designed to deliver extremely low frequencies in conjunction with stereo pairs of studio reference monitors such as the M-Audio Studiophile BX8 or BX5.
First Things First 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. In the Box Carefully remove the SBX from the carton, paying extra attention to avoid touching or damaging the speaker cone.
Rear Panel Features: 1. Power Mode LED: This LED indicates the power status. If the auto-muting circuitry is engaged, this LED will be amber if there is no audio signal to the SBX, and green when the SBX receives a signal. If “Auto-Power” is switched off, then this LED will remain green.

Connecting the SBX and Y our Main Speakers 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.
Using the SBX without Stereo Bass Management Y ou 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.
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.
Optimizing the Rear P anel Settings There are four control knobs on the rear of the SBX: “Level,” “Phase,” “Subwoofer” LPF cutoff frequency , and “Satellites” HPF cutoff frequency .
Setting the Subwoofer LPF and the Satellites HPF The fundamental concept behind the Stereo Bass Management System is to isolate the upper and lower frequency ranges and direct them respectively to the component best suited to reproduce them.
This crossover network consists of two main components: a 2nd order (12 db/octave) low-pass filter that limits the upper frequencies that the subwoofer has to reproduce (shown above), and a high-pass filter that limits the lower frequencies the satellite monitors have to reproduce (shown below).
If your satellites are properly damped at the bass response as shown in curve “a,” set the two crossover frequencies to be identical. If your satellite speakers are under -damped (boomy sounding) as shown in cur ve “b,” experiment with setting the Satellite crossover frequency control higher .
while gradually increasing the volume of your audio system. If you begin to hear a sustaining sound quality before you are able to advance the volume control to a setting representing loud listening, acoustic feedback is a problem. Y ou may need to move either the turntable or the SBX to remedy this problem.
