Proficient’s S88 Compact Floor Standing Subwoofer provides accurate bass to any audio system, and is designed to work in conjunction with your other audio components. The S88 can be connected to any surround sound receiver that has a subwoofer output, any receiver that has a built-in preamplifier or any receiver that has speaker level outputs. INTRODUCTION For optimal performance, the S88 should be placed in a corner along the same wall as the front speakers. The unit is not shielded, so do not place it too close to video devices. When choosing a place for the S88, please keep the following in mind: Placing the S88 in a corner will increase the bass output, for details on placement, consult your local Proficient dealer. DO • Place the S88 with its feet resting on a solid flat level surface. • Place the 88 in a well-vented area to provide proper cooling. In areas that lack proper ventilation, such as tight cabinets or racks, it may be necessary to install small fans to create air movement. DON’T • Obstruct the woofers of the S88 it will hinder performance. • Place the S88 in any position other than horizontal with the feet down. Never place on its side or resting on the back where the terminals are located. • Place the S88 near heat sources or in an area that it would be exposed to moisture. PLACEMENT 2 APPLICABLE FOR USA, CANADA OR WHERE APPROVED FOR USAGE CAUTION: TO PREVENT ELECTRIC SHOCK, MATCH WIDE BLADE PLUG TO WIDE SLOT, INSERT FULLY. ATTENTION: POUR EVITER LES CHOCS ELECTRIQUES, INTRODUIRE LA LAME LA PLUS LARGE DE LA FICHE DANS LA BORNE CORRESPONDANTE DE LA PRISE ET POUSSER JUSQU AU FOND. WARNING RISK OF ELECTRIC SHOCK DO NOT OPEN CAUTION: To reduce the risk of electric shock, do not remove cover (or back). No user-serviceable parts inside. Refer servicing to qualified service personnel. IMPORTANT SAFETY INSTRUCTIONS The lightning flash with arrowhead symbol, within an equilateral triangle, is intended to alert you to the presence of uninsulated “dangerous voltage” within the product’s enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons. The exclamation point within an equilateral tri- angle is intended to alert you to the presence of important operating and maintenance (servicing) instructions in the literature accompanying the appliance. • Explanation of Graphical Symbols WARNING RISK OF ELECTRIC SHOCK DO NOT EXPOSE TO MOISTURE • To reduce the risk of fire or electrical shock, do not expose the apparatus to rain or moisture. • A warning that an apparatus with CLASS I construction shall be connected to a MAINS socket outlet with a protective earthing connection. PORTABLE CART WARNING CAUTION: Please read the following important instructions carefully to ensure a safe operation.

Connecting the Line Level Audio Inputs (See Figure 1) If your surround sound receiver or amplifier has only one subwoofer output, simply plug it into the Left Line Input. If your receiver or amplifier has a built-in preamplifier, the left and right pre-outputs can be connected to the left and right line level inputs. Connecting the Speaker Wires (See Figure 1) If you choose to hookup speaker wire instead of RCA line level patch cords, follow these instructions when using the Speaker Level Outputs of your receiver or amplifier to connect to the S88. For best results, use speaker wire that is at least 16 gauge. For runs longer than 75 feet, 14 gauge wire is recommended. Wire larger than 14 gauge is not recommended because it may not fit into the connector. For best results, strip all wire insulation no more than 3⁄8" from the end before inserting into the connector. 1. Strip the speaker wires’ insulation 3⁄8" from the end. 2. Connect the wires from the speakers to the appropriate location above “To Speakers”. Please observe proper polarity of the connections (+ to + and – to –). 3. Connect the amplifier’s or receiver's speakar outputs to the appropriate location above “From Receiver”. Please observe proper polarity of the connections (+ to + and – to –). CAUTION: If the “To Speakers” and “From Receiver” connections are reversed, a short could result across the amplifier or receiver output terminals, which may seriously damage your amplifier or receiver. Please double-check all connections before turning on your amplifier or receiver. INSTALLATION The S88 Powered Subwoofer is designed to function trouble-free. Most problems occur due to operating errors. If you have a problem, please check the troubleshooting list first. If the problem persists, contact your authorized Proficient dealer or Proficient Technical Support at 800.448.0976. TROUBLESHOOTING A hum or buzzing sound is heard. The sound may be caused by a ground loop in the system. Try to eliminate this by reversing the AC plugs of other components in the system. Try plugging the receiver into another outlet. Other causes may include faulty cables. The S88 will not turn on. The subwoofer must be plugged into a live AC outlet. The power switch on the back panel must be on. A signal must be playing into the input jacks. No sound is heard. Audio cable to the receiver is not connected properly or the cable is bad. Use another cable that you know is good. Check all wire connections and plugs. Problem Possible Causes & Solutions Figure 1: Line Level Inputs Speaker Level Inputs/Outputs Once the S88 is connected, use the controls described below to make adjustments so that it will blend seamlessly with the other speakers in your system. Power Switch This switch turns the S88 on or off. The Standby light will illuminate green when switched to the “On” position; when “Off”, the Standby light will illuminate red. Volume Knob (See Figure 2) Use this control to match the output of the S88 to that of the main speakers in the system. We recommend that you play a variety of material before selecting a setting. Start with the control in the 12 o'clock position for the optimal setting and adjust to your system as necessary. Crossover Knob (See Figure 2) Use this control to adjust the upper frequency limit of the S88. The purpose is to control the overlap the upper frequencies of the sub and the main speakers’ lower frequencies. Start in the 12 o’clock position for the optimal setting. Crossover Bypass Switch (See Figure 3) Bypass the internal crossover on the S88. The default setting is “Off”. Phase Switch (See Figure 3) Allows you to toggle between 0° and 180° phase modes. Listen to the system and leave the switch in the position that has more audible bass. The default setting is “0˚”.
