All Rights Reserved. 3 Introduction Thank you for choosing a TAPCO SW·10 Active Studio Subwoofer. The TAPCO product line hails back to the days of TAPCO Corporation, Greg Mackie's first company. TAPCO revolutionized the audio industry back in 1969 with the very first 6-channel mixer specifically designed for keyboards and rock `n' roll. In essence, TAPCO redefined the price/performance ratio and made high-quality professional audio equipment accessible to virtually anyone. Today, TAPCO is reborn with the same ideals and is backed by the world-class engineering and manufacturing horsepower of Mackie and LOUD Technologies. The TAPCO SW·10 joins the S·5 and S·8 of the active studio monitor line in the TAPCO by Mackie® family. These versatile compact "mini-monitors" and "mini-subs" can be used in a variety of applications, including small project studios, surround sound editing, home theater playback, and desktop audio workstations (DAWs). The SW·10 active studio subwoofer is an acoustic suspension design for tight, articulate bass that provides an amazingly flat and linear low-frequency response down to 34 Hz. The active crossover is a Linkwitz-Riley design that provides a range of 55 Hz to 110 Hz at 24 dB/octave. The individual crossover controls for the left and right channels provide additional flexibility in surround sound applications with a subwoofer output and bass management (LFE). Here's a quick look at all the features packed into the SW·10 Active Studio Subwoofers: · Flat frequency response (±3 dB, 34 Hz to 110 Hz) · 10" paper cone woofer with dual-voice coil design · Convenient compact design · Horn-loaded design for high efficiency · 120 watt power amplifier · High-strength cabinet constructed of 5/8" MDF composite · High-density adiabatic fiberfill absorbs internal reflections · Balanced XLR and unbalanced RCA input connectors · Balanced XLR and unbalanced RCA high-pass output connectors · Individual left and right 24 dB/octave Linkwitz-Riley crossovers, adjustable from 55 Hz to 110 Hz · Adjustable sensitivity control · Polarity switch · Rear panel power switch and AC voltage select switch TAPCO van (a.k.a. micro bus) 4 Getting Started The following steps will help you set up your subwoofer quickly. INITIAL SETTINGS: 1. Turn the INPUT SENSITIVITY control on the rear panel all the way down (MIN). 2. Set the left and right CROSSOVER controls to the center position (80 Hz). 3. Set the POLARITY switch out (0º). 4. Turn the POWER switch OFF. 5. Set the AC SELECT switch to the correct position for your country (115 VAC or 230 VAC). LOOK CLOSER Now that you have your subwoofer working, it's time to hunker down and read the rest of this manual...especially the following: Placement An Extremely Important Note on SW·10 Bass Response and Your Control Room or Listening Room You've heard it before. "Low-frequencies are non-directional, so it doesn't matter where you place the subwoofer." Although it is true that frequencies below about 100 Hz are non-directional, it is also true that a lot of factors can conspire to thwart the SW·10's extended low frequency -- including room shape, room volume, and acoustical treatment. This is not a cop-out or an apology. It's plain old physics in action. Here are some tips to help you find the best placement for your SW·10 and optimize the low-frequency response in your particular room. Consider the following: CONNECTIONS: 1. Connect the left and right line-level signal from your mixer (or other signal source) to the LEFT and RIGHT INPUT jacks on the SW·10 (XLR or RCA). 2. Connect the LEFT and RIGHT OUTPUT jacks on the SW·10 (XLR or RCA) to the inputs of the left and right main powered speakers (or to the inputs of the amplifiers powering the left and right main speakers). 3. Connect the supplied AC power cord to the IEC socket on the back of the subwoofer. Plug the other end into an AC outlet properly configured with the correct voltage for the AC SELECT switch setting you have selected. Room acoustics and bass-handling ability Nobody likes to buy a subwoofer and a new set of speakers and then be told that they should spend extra bucks on bass traps or a remodeling job. But the simple fact is, "standard" rooms, i.e., rectangular rooms in conventional business or residential structures, are rarely if ever conducive to optimal low-bass reproduction without some modifications. However, understanding what can cause degradation of the low-frequency response in a room can help in choosing a location that can minimize the problems associated with poor bass response--most notably interference and resonance. Interference is caused when the reflected wave from the surrounding walls arrive out- TURN IT ON: 1. Turn on the power to the other components in the system. Generally, it is best to turn on powered speakers and amplifiers last to avoid thumps and pops from getting to the speakers. 2. Turn on the POWER switch on the back of the SW·10. 3. Start your signal source (tape deck, CD, DAW, or whatever), but leave the master level control on your mixer down. 4. Adjust the master volume on your mixer to a comfortably loud listening level. 5. Slowly turn up the INPUT SENSITVITY control on the SW·10 to MAX (fully clockwise), or until you achieve a balance between the subwoofer and the other speakers in the system. 6. Enjoy the authoritative, commanding lows of the SW·10. 5 SW·10 ACTIVE STUDIO SUBWOOFER CROSSOVER CROSSOVER INPUT SENSITIVITY 80 80 POLARITY 55 110 MIN MAX 0 180 O O 55 110 LEFT INPUT L R RIGHT UNBALANCED OUTPUT L R UNBALANCED AC SELECT WARNING: TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK, DO NOT EXPOSE THIS EQUIPMENT TO RAIN OR MOISTURE.

This can weaken or even cancel the sound. Keeping the distance between the subwoofer driver and any adjacent walls no longer than 1/8 of a wavelength (20 in or 51 cm at 80 Hz) can minimize interference. Room resonance is caused by the reinforcement of certain frequencies between 20 Hz and 200 Hz, which creates "standing waves" or room modes. These resonant frequencies are determined by the dimensions of the room. The bass response is sharply boosted for a narrow band near resonance, and then appears to be attenuated between resonances. Corner or Center Placement Placing the subwoofer in a corner (corner loading) excites the most room modes in the room, which tends to smooth the individual peaks and dips caused by each standing wave. Moving the subwoofer outward from the corner along the wall results in fewer standing waves, but may result in noticeable peaks at certain frequencies. Some people prefer to place the subwoofer between the left and right main speakers, so that all the sound is coming from the same plane. Some prefer to use two subwoofers and place one with the left speaker and the other with the right speaker. Another benefit of corner placement is increased efficiency and lower distortion. The energy that is reflected off the walls 6 115V RISK OF ELECTRIC SHOCK DO NOT OPEN reinforces the direct sound, putting less of a demand on the power amplifier to reach higher sound pressure levels. It is important that the corner has good structural strength, or the low-frequency energy can cause rattling and other distracting vibrations. Experiment with the orientation of the subwoofer. The driver in the SW·10 faces out the front. It may be helpful to play steadystate tones or pink noise while a partner moves the subwoofer (perhaps on a small wheeled cart), to make it easier to hear the differences in the sound as the changes in placement and orientation are made. Feel free to experiment In many respects, every room is unique in terms of its acoustics. Even after you've placed your subwoofer where you think it will sound best, try moving it around. You might be pleasantly surprised. Additional Tidbits of Wisdom: · Avoid using EQ to compensate for dips in the frequency response caused by room modes. It is better to place the subwoofer in a position where dips are minimized and use the EQ to smooth out any peaks. · Provide at least six inches clearance around the heatsink to allow air to get at it. · Never listen to loud music for prolonged periods. Please see the Safety Instructions on page 2 for information on hearing protection. · When you shut down your equipment, turn off the SW·10 active studio subwoofer first (and any other powered speakers in the system) to prevent thumps and other noises generated by any upstream equipment from coming out the speakers. When powering up, turn on the powered speakers and subwoofer last. · Save the shipping boxes and packing materials! You may need them someday. Besides, your cat will love playing in them and jumping out at you unexpectedly. Remember to pretend like you are surprised! · Save your sales receipt in a safe place. · Also record the SW·10 serial number in the space provided on the inside front cover, along with where and when you bought it. Principle of Reciprocity One trick that has been used successfully to find the best location for a subwoofer is placing the subwoofer in your listening position. The principle of reciprocity says that you can find the best location for the subwoofer by switching places between the listening position and the subwoofer position. It is important that the cabinet be raised off the ground and at the same level as your ears. If that's not possible, at least put the subwoofer in the same location as your listening position to achieve a close approximation. Play music with a good strong bass line and crawl on the floor on your hands and knees until you find a spot where the bass sounds the best, with a smooth, tight response. Your ears need to be at the same height that the subwoofer's driver will be when it is sitting on the floor. If you have access to a real-time analyzer (RTA), play pink noise over the system and use the RTA to find a location that exhibits the flatest bass response. Once you've found the place where the bass sounds the best, put the subwoofer there and it should sound just as good from your listening position. Polarity The setting of the polarity switch can affect how the low frequencies sound in relation to the main speakers. Listen to bassheavy music with the polarity switch in and out. In one position the low frequencies should sound full, while in the other position they may sound hollow and thin. Choose the position that yields the fullest lowfrequency sound. 7 Hookup Diagram Typical Hookup Left Main/Satellite Powered Monitor Right Main/Satellite Powered Monitor Surround Sound Preamplifier OR 1 2 AUX RETURN (MONO) IN From Mixer or Preamplifier Left and Right Outputs SW·10 ACTIVE STUDIO SUBWOOFER CROSSOVER CROSSOVER INPUT SENSITIVITY 80 80 POLARITY AUX SEND CTRL ROOM MAIN L 1 MON OUT L OUT L OUT R INST IN (HI-Z) INPUT MIC U LEVEL SET EFX LINE IN 2 R TAPE OUT R PHONES 55 110 MIN MAX 0 180 O O 55 110 INST IN (HI-Z) INPUT MIC U LEVEL SET LINE IN 3/4 (MONO) 5/6 CD/TAPE IN (MONO) L L L LEFT INPUT L R RIGHT R +3 +50 -22dB +25dB +3 +50 -22dB +25dB R BAL/UNBAL R GAIN GAIN BAL/UNBAL 6306 U EQ 12k U EQ 12k U EQ 12k U EQ 12k LEFT RIGHT HI HI HI HI POWER OL 16 12 8 UNBALANCED -15 +15 U -15 +15 U -15 +15 U -15 +15 U LOW 80Hz LOW 80Hz LOW 80Hz LOW 80Hz 4 +48V PHANTOM POWER NRM 0 -4 -12 -24 0 = +4dBu -15 +15 U -15 +15 U -15 +15 U -15 +15 U OUTPUT L R AUX 1 MON AUX 1 MON AUX 1 MON AUX 1 MON U RETURN AUX TO MAIN O O O O MAX O O MAX O O MAX O O MAX MAX U U U U U PHONES 2 EFX O O 2 EFX O O 2 EFX O O 2 EFX O O TO MON O O MAX MAX MAX MAX MAX O O MAX UNBALANCED L R L R L R L R PAN PAN BALANCE BALANCE MAIN CD/TAPE O O MAX CTRL ROOM 1 U U 2 U 3/4 U 5/6 OFF MAIN MAIN U WARNING: TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK, DO NOT EXPOSE THIS MAX EQUIPMENT TO RAIN OR MOISTURE.

LEFT AND RIGHT OUTPUTS · Balanced XLR male and unbalanced RCA female connectors are provided for the line-level left and right high-pass outputs. Connect these to the inputs of the main speakers (if they are powered speakers) or to the inputs of the amplifier powering the main speakers. · The signal at the left and right outputs is postcrossover. The low-pass output from the crossover goes to the internal power amplifier in the SW·10, while the high-pass output goes to these output jacks. 1. INPUT SENSITIVITY · The SW·10 expects a line-level signal at its inputs. · The left and right low-pass signals are summed after the crossover section. Use this control to adjust the sensitivity of the low-pass signal feeding the internal power amplifier. 2. CROSSOVER · There are two crossover controls, one for the left input signal and one for the right input signal. · These adjust the crossover frequency for the builtin 24 dB/octave Linkwitz-Riley variable crossovers. · The crossover frequency can be adjusted from 55 Hz to 110 Hz. 6. AC SELECT Set this switch to the correct voltage setting for the country you are in, 115 VAC or 230 VAC. Note: The SW·10s are shipped with the AC SELECT switch set to the 230 VAC position. If you are in a country that uses 100-120 VAC, set the switch to the 115 VAC position and replace the fuse (located in the IEC socket) with the 1.6 A fuse included in the accessory bag. See the "Troubleshooting" section on page 11 for instructions on replacing the fuse. 3. POLARITY · This switch reverses the polarity of the signal going into the subwoofer amplifier by 180°. It has no effect on the signal at the Left and Right Outputs. · There is no right or wrong setting for this switch. Listen to the overall blend of the subwoofer with the rest of the system, and select the switch position that gives you the best sound. 9 4. LEFT AND RIGHT INPUTS · Balanced XLR female and unbalanced RCA female connectors are provided for the left and right inputs. Connect the full-range line-level signal from the mixer or preamplifier to these input jacks. The connectors are wired as follows (per the AES/ IEC standard): XLR Hot (+) Cold (­) Shield (GND) Pin 2 Pin 3 Pin 1 RCA Tip -- Sleeve SW·10 ACTIVE STUDIO SUBWOOFER CROSSOVER CROSSOVER INPUT SENSITIVITY 1 3 80 80 POLARITY 2 55 110 MIN MAX 0 180 O 2 O 55 110 LEFT INPUT L R RIGHT · If connecting a single subwoofer output or LFE output to the SW·10, you can use either the LEFT or RIGHT INPUT connector. · CAUTION: NEVER connect the output of an amplifier directly to the input of the SW·10.

POWER Use this switch to turn the SW·10 on and off. Protection Circuits There are several protection mechanisms designed into the SW·10 to safeguard the loudspeakers and amplifiers from inadvertent damage. 8. Line Cord Socket and Fuse Connect the line cord to this IEC socket securely, and plug the other end into your AC outlet. Make sure the AC SELECT switch is set to the correct AC voltage. The fuse is located behind the fuse cover, at the bottom of the IEC socket. See the "Troubleshooting" section on page 11 for information about replacing the fuse. Peak Limiter A peak limiter monitors the amplifier output signal to guard against clipping and overloading the amplifier. This allows for loud punchy bass performance without distortion, ensuring long-term reliability. 9. Heatsink The heatsink is designed to dissipate the heat generated by the built-in power amplifier. The cooler the amplifier operates, the longer its life-expectancy. The SW·10 uses convection cooling, where cool air flows through the fins of the heatsink and carries the heat away. Make sure there is at least six inches clearance between the back of the SW·10 subwoofer and the wall. Thermal Protection All amplifiers produce heat. The SW·10 is designed to be efficient both electrically and thermally. · If for some reason the heatsink gets too hot, a thermal switch activates and turns off the amplifier. · When the heatsink cools down to a safe temperature, the thermal switch resets and normal operation resumes. · If the heatsink temperature again gets too hot, the shutdown process repeats. Should this happen, make sure that airflow to the rear of the cabinet is not restricted. If the ambient air temperature is very warm, try pointing a small fan toward the heatsink to increase the airflow through the fins. 9 Input Signal Wiring You should use high-quality, shielded cable to connect the signal source to the INPUT jacks on the SW·10. · Foil shielded cables, such as Belden 8451, 8761, or 9501 are commonly used for studio wiring. · Microphone cables work well for XLR connections. · The better the shield, the better the immunity from externally induced noise (like EMI and RFI). Route the cable away from AC power cords and outlets. These are common sources for hum in an audio signal. You can purchase quality cables from your Mackie dealer. · See "Appendix B: Connections" for info on the types of connectors to use.

If you think your TAPCO SW·10 has a problem, please do everything you can to confirm it before calling for service. Doing so might save you from the deprivation of your subwoofer and the associated suffering. These may sound obvious to you, but here are some things you can check. Read on. No Sound · Is the INPUT SENSITIVITY control turned up? · Is the signal source turned up? Make sure the signal level from the mixing console (or whatever device immediately precedes the subwoofer) is high enough to produce sound. Bad Sound · Is the input connector plugged completely into the jack? · Is it loud and distorted? Reduce the signal level at the mixer. · If possible, listen to the signal source with headphones plugged into the preamp stage. If it sounds bad there, it's not the subwoofer. · Too much bass or not enough bass? Move around the room and see if the bass response changes. It's possible your listening position coincides with a room mode where the low frequencies either become exaggerated or nulled. If so, try moving the subwoofer to a different position, or moving your listening position. Also, try switching the polarity switch. Troubleshooting No Power · Our favorite question: Is it plugged in? · Make sure line cord is securely seated in the line cord socket and plugged all the way into the AC outlet. · Make sure the AC outlet is live (check with a tester or lamp). · Is the POWER switch in the ON position? · If you are certain that the AC outlet is live and there is still no power, it is possible the fuse has blown. To remove and replace the fuse: 1. Disconnect the power cord from the IEC socket. 2. Remove the fuse drawer by prying it open with a small screwdriver. It will slide all the way out. Noise/Hum · Check the signal cable between the mixer and the subwoofer. Make sure all connections are secure. These problems usually produce crackling noises or hum. · If connecting an unbalanced output to the SW·10 balanced input, make sure the shield is connected to the unbalanced ground and to pin 1 of the XLR. · If a CATV cable is connected to the system, try disconnecting it. If the hum goes away, call your cable carrier to check for proper grounding of the cable. FUSE 3. Remove the fuse and replace it with an equivalent-type fuse. 115 VAC unit: 1.6 amp slo-blo (T 1.6 A H/250 V) 230 VAC unit: 800 milliamp slo-blo (T 800 mA H/250 V) 4. Replace the fuse drawer by pushing it all the way back into the IEC socket. If two fuses blow in a row, then something is very wrong. See the "Repair" section on the next page to find out what to do. · Make sure the signal cable is not routed near AC cables, power transformers, or other EMI sources (including wall warts and line lumps!). These sources usually produce hum. · Is there a light dimmer or other triac-based (SCR) device on the same AC circuit as the subwoofer? Dimmers cause buzzing noises. Use an AC line filter or plug the subwoofer into a different AC circuit. · If possible, listen to the signal source with headphones plugged in. If it sounds noisy there, it's not the subwoofer. 11 Repair Service for TAPCO products is available at one of our factory authorized service centers.

Ask Tech Support for the latest turn-around times when you call for your Service Request Number. The subwoofer must be packaged in its original packing box, and must have the Service Request Number on the box. Once it's repaired, we'll ship it back the same way in which it was received. This paragraph does not necessarily apply to non-warranty repair. Note: You must have a sales receipt from an Authorized TAPCO Dealer to qualify for a warranty repair. Lonely?
