provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation.
Whichever PSB subwoofer you have chosen, we hope that you appreciate the attention to detail that has gone into its design. Please take the time to read the following sections about the placement of your subwoofer, its connections and adjustments. Enjoy your PSB subwoofer. III. QUICKSTART If you cannot wait to hear your new PSB subwoofer, then: Turn off all other components and follow one of the connection diagrams. Connect the supplied power cord to the AC power socket.
PHASE SWITCH OR CONTROL Selects the subwoofer output phase between in-phase (0˚) and out-of-phase (180˚). See “VII Setup Calibration” HIGH/SPEAKER LEVEL INPUT TERMINALS (if applicable) Left Right HIGH LEVEL INPUT FROM RECEIVER Left Right HIGH LEVEL OUTPUT TO SPEAKERS LOW LEVEL INPUT FROM PREAMP Left Right LOW LEVEL OUTPUT TO AMP Left Right LFE INPUT LFE OUTPUT For connecting the PSB subwoofer to receivers or integrated amplifiers equipped with speaker outputs only.
AC POWER SOCKET* AC POWER SOCKET Supplies AC power to the PSB subwoofer. Connect the supplied power cord to the AC power socket. Plug the power cord into any standard wall outlet. The same receptacle as the rest of the system or another on the same electrical circuit should be used to avoid ground hum. The PSB subwoofer has its own self-contained amplifier and thus requires AC power (keep this in mind when selecting a location).
V. ROOM ACOUSTICS, SUBWOOFER PLACEMENT, MULTIPLE SUBWOOFERS & CONTROL SETTINGS A. Room Acoustics If you are critical about low-frequency response, there’s quite a bit of useful experimentation you can do, especially in combination with the crossover, level, and phase controls of our subwoofers. Begin by considering the size of the listening room. The larger the volume of air a speaker must move, the more acoustic output is required to achieve the sound levels you want.
The best method for positioning a subwoofer is to put the subwoofer in your listening chair, then play music with lots of bass through the system (something with steady low frequencies or continuous test tones). Move around the room and note where the bass sounds best; if you place the subwoofer in that location, you should get the same bass performance. This test only works if you have your ears at the same height as where the subwoofer will be, so you may have to get down low.
use multiple subwoofers to diffuse such sounds. Subwoofers also offer a phase control so the upper frequencies produced will not cancel out the lower frequencies of the satellites. Adjustment of this control can have great effect on spectral smoothness in the crossover area. Phase changes with frequency, however, so these controls may need readjusting every time you vary the cutoff frequency. The overall level of the subwoofer’s output may also be adjusted.
If your receiver or integrated amplifier has preamplifier outputs, or if you are using a separate preamplifier, the preferred connection is from the Preamplifier Output of the electronics to the Low Level Input of the subwoofer. Use a dual RCA audio cable. Additionally, you may need to use Y-connectors at the Preamplifier Output to also send signals to the Power Amplifier/Main Input.
VII. SET-UP CALIBRATION The following procedure assumes your PSB subwoofer is installed and connected. If possible, work in a team with another person: one listening, one making subwoofer-control adjustments. 1. Set Sub Volume to 0, Sub Cut-Off Frequency to 50Hz. Set any loudness, bass and treble, and/or equalizer controls on your preamplifier or integrated amplifier or receiver, or other components, to their nominal (midpoint or off) positions. 2.
VIII. TROUBLESHOOTING Symptom No sound On/standby indicator not lit Action Ensure the main power switch is on. This switch is located at the back of the subwoofer. Ensure the power cord is connected to the subwoofer and plugged into a live AC outlet. Check the main fuse located in the power cord socket and replace as required. If the new fuse also blows, the subwoofer amplifier requires service. No sound On/standby indicator remains red All PSB subwoofers utilize signal sensing auto on/off circuitry.
Symptom Sounds distorted Hum Action Lower volume if the subwoofer begins to sound distorted to determine if playback at a lower level solves the problem. If a slight reduction in level solves the problem, then the subwoofer level was too high. If the distorted sound remains at a low level, driver(s) may be damaged.

Alpha S8 Powered Subwoofer Designed & Engineered in Canada Why You Need a Subwoofer The subwoofer is a fairly recent entrant to the typical home entertainment system, and we see the concept popping up in even low-price desktop systems. The idea of having a separate bass speaker was first encountered in cinemas and public address systems where a lot of audio power was needed to fill the theater or stadium.
Why PSB Should be Your First Choice SPECIFICATIONS If you just want a big booming sound almost any subwoofer will do. However, if you want to create a realistic sound field in your listening room the experience and expertise of PSB should make it your first choice. The key to getting accurate bass is both in tuning the subwoofer acoustically, and in properly integrating it with the other speakers in the system.
