Frequently Asked Questions - PC-Sub WL12 Phase Technology

How do I pair the wireless transmitter with the subwoofer?

Press the RESET button on the back of the subwoofer once (blue LED blinks quickly). Then press the button on the bottom of the transmitter once (blue LED blinks quickly). After a few seconds, both LEDs stay solid. If pairing fails, press the transmitter button again. For two subwoofers, press the second transmitter button twice.

Can I use both wired and wireless connections at the same time?

No. Use either the wireless setup (with transmitter) or the wired direct connection (RCA from receiver to Line In). Do not connect both simultaneously.

What is the recommended placement for the subwoofer?

Subwoofer placement is flexible due to omnidirectional low frequencies. For best bass, place near a wall or corner (increases output). If using two subwoofers, start with them near front left/right speakers or in corners. Experiment with placement and adjust gain to compensate.

How do I set the crossover frequency?

If your A/V receiver handles bass management, set the subwoofer's Low-Pass control to LFE. If using the sub's internal crossover, adjust between 35-120 Hz to match your main speakers' low-frequency cutoff. Listen to bass-heavy music and choose the fullest sound.

What does the phase switch do?

The Phase Switch (0° or 180°) matches the subwoofer's cone movement to your main speakers. Adjust while playing music with bass; the setting that produces the fullest bass is correct.

Why is there no sound from the subwoofer?

Check that the subwoofer is plugged in and powered on (LED should be green when receiving signal). Ensure the wireless transmitter is paired and connected to your receiver's Sub Out. For wired connection, verify RCA cable is secure. Also check that the receiver's subwoofer output is enabled.

How do I clean the subwoofer cabinet?

Use a lint-free rag with a small amount of glass cleaner. Avoid products containing silicones, oils, or solvents. For vinyl laminate finishes, a damp cloth is sufficient.

What should I do if the bass sounds muddy or boomy?

Reduce the subwoofer's volume. Try lowering the crossover frequency (e.g., from 120 Hz to 80 Hz). If the sub is near a wall or corner, move it away. For bookshelf speakers in cabinets, relocate them to an open space.

What are the vibration isolation pads for?

The four adhesive-backed gray pads prevent the subwoofer from moving on hard floors at high volume. Peel off the paper and apply one pad to each rubber foot.

How do I obtain warranty service?

Contact Phase Technology (MSE Audio) at 855.663.5600 or [e-mail] for a Return Authorization number. Unauthorized returns will be refused. The warranty covers speaker product for 10 years and electronic components for 3 years (original purchaser).

[PC SUB WL]subwoofers

[GETTING STARTED AND PRECAUTIONARY NOTES]

For proper connection and therefore full enjoyment of your new Phase Technology speakers, we encourage you to read this owners' manual thoroughly, even if you are very familiar with installing speakers and home entertainment equipment.

Speaker placement is very subjective. Placement follows the guidelines for the developers of multi-channel home entertainment systems, yet is also guided by personal preferences. The proper spacing, location and adjustment of front, rear and center-channel speakers as well as subwoofers are critical for complete enjoyment of your new speakers. This manual covers these topics thoroughly.

Before connecting your new speakers or other system components, turn the system power off and unplug your amplifier to avoid any possibility of damage from power surges or unbalanced loads before the system is properly connected.

Observe speaker polarity carefully! Every cable, speaker terminal and amplifier connection are clearly marked to show their positive (+) and negative (-) polarities. For ideal system performance, always connect the positive side of the cable (marked with a stripe, color and /or other indicator) to the positive terminals on your speakers and amplifier and the negative side of the cable to the negative terminals.

Amplifier selection is critical to your enjoyment of your new speakers. If you are considering upgrading your current component amplifier or multi-function receiver, we suggest purchasing as much power as your budget can afford. It will always be preferable to have an affordable high-powered model with fewer “bells and whistles” than a lower-powered model straining to operate near its power limits.

High volume settings that produce audible distortion – indicating an under-powered amplifier – could eventually damage your speakers and your amplifier.

Begin and end listening sessions at low volume levels so you will not power up your system the next time with possibly harmful high voltages. A damaging surge also could result if you change the input source (from FM tuner to CD player, for example) at high volume levels.

If you suspect that one channel of your amplifier has failed, have it repaired immediately by your dealer. Damage to your speakers could occur if you switch between the good and defective channels.

[SUBWOOFER PLACEMENT]

Subwoofer placement is less critical, because the frequencies they reproduce are omni directional. This means the human ear doesn't perceive these low frequencies as coming from a specific direction, enabling placement of a subwoofer virtually anywhere in the listening room.

It's best, however, to keep a subwoofer within the sound field of the other speakers. The closer the subwoofer is to a wall, the louder and more intense its bass output will be: this effect is even stronger when the sub is placed in or near a room's corner. If using two subwoofers, start by placing them next to the front left and right speakers, in both front corners or one in the corner and one 1/3 of the way along the front wall from the corner. Each room is different. Experiment with these options or try other locations until you get the best results. If you must choose a less-than-ideal position, the output level of Phase Technology powered subwoofers is adjustable to compensate for your listening environment.

[SPEAKER CONNECTIONS]

The following instructions apply whether you are using a separate amplifier or Home Theater receiver. For simplicity we will use the term “amplifier” throughout this manual to mean both.

Special note: Turn off and unplug your amplifier before connecting speakers.

Special Note: Observe Speaker Polarity Carefully!

Every cable, speaker and amplifier is clearly marked to show their positive (+) and negative (-) terminals. Amps and speakers may use some combination of these symbols and/or colors to indicate positive (usually red) and negative (usually black or white) connections. One strand of your cable will also be ridged and/or marked with a colored line or other indicator on the positive side. For proper polarity and, thus, ideal system performance, always connect the positive side of the cable to the positive terminals on your speakers and amplifier and the negative side of the cable to the negative terminals.

[HOOKING UP YOUR PC SUB-WL SUBWOOFER]

OPTION 1: WIRELESS SETUP The PC SUB WL wireless transmitter includes a power adapter. This power adapter is a universal adapter and is designed to operate on household power of 100-240V and 50/60Hz. Plug the power adapter into a convenient power outlet and the small coaxial power plug into the rear of the transmitter socket labeled "DC In +5V". The transmitter should power up and display a blue LED light on the front of the unit.

Next, connect the "SUB/Left IN" on the wireless transmitter to the "Subwoofer Out", "SUB OUT", or "Pre-Amp Out" connection on the rear of your receiver or processor using a dedicated RCA interconnect cable. Plug the PC SUB WL into a wall outlet and turn the power switch on. The power LED should turn red and the Wireless Status LED should be blue. The transmitter and the subwoofer now need to be synchronized (paired) so that they will recognize each other.

TRANSMITTER/RECEIVER PAIRING INSTRUCTIONS Up to two PC SUB WL Subwoofer systems can work in close proximity. When using two subwoofers each needs to be paired to its own transmitter. Pairing is done as follows:

1. Press the RESET button for the receiver unit on the back of the subwoofer once. The blue LED will start blinking quickly.

2. Press the button located on the bottom of the transmitter unit once. The Blue LED will start blinking quickly. After a few seconds both blue LEDs will stay on continuously. If pairing is not successful the blue LED on the Transmitter will start blinking slowly after 10 seconds. In this case, press the button on the transmitter again.

Note: There is no need to press the receiver button again (the button on the back of the subwoofer). The flashing Receiver LED indicates that the receiver is waiting for a transmitter to connect to it.

Two wireless PC SUB WL subwoofers can be used simultaneously, but each requires its own transmitter. If you already have one system installed, then repeat the above process but press the transmitter button on the second transmitter twice in order to avoid interference with the first system. Our wireless topology uses adaptive frequency hopping. If interference is detected the transmitter and receiver automatically switch to another channel. If for some reason the pairing is interrupted then re-pairing will resolve the problem and return the system to normal operation.

NOTE: Recommended wireless operating range is 50 feet. The range depends on usage and obstructions between the transmitter and receiver.

OPTION 2: WIRED DIRECT CONNECTION SETUP This is the recommended (wired) method of connection for those applications where the Wireless Transmitter will not be used. Never attempt to connect your PC SUB-WL using both the wired and wireless hookups.

Most A/V receivers and processors are equipped with a "Subwoofer Out" or "Pre-Amp Out" connection. Run a dedicated RCA interconnect cable from the "SUB OUT" terminal on your receiver or amplifier to the "LINE IN" terminal on the subwoofer.

Amplifier Panel

[AMPLIFIER SETUP AND BASS MANAGEMENT]

Many home theater receivers/processors have a feature that controls how the bass is processed and delivered to the subwoofer. It also adjusts the amount of bass that is sent to your satellite speakers. Look carefully in your amplifier or receiver's instruction manual for details on how to adjust for the speaker size (sometimes called "Speaker Setup") for your system.

[SUBWOOFER AMPLIFIER PANEL]

1. Power/Auto ON/OFF: When this switch is left "ON", the subwoofer automatically activates upon detection of an audio signal; the subwoofer goes into "STANDBY" after approximately ten (10) minutes of silence. The LED on the amplifier will change from Red to Green when an input signal is detected and the amplifier turns on.

2. Power Input: Connects to a standard AC power outlet with the supplied power cord. The PC SUB WL is designed to adjust automatically to handle power sources of 100-240V, 50-60Hz. Please be certain that the proper fuse is installed on the amp for the input voltage used locally (see ratings on amplifier panel).

3. Wireless Signal: Blue LED light is on when wireless signal is being received. Press RESET to establish or re-establish a wireless connection. (See wireless set up instructions)

4. Line In: FOR WIRED CONNECTION ONLY: Using a high-quality RCA cable, connect the "SUB OUT" terminal on your receiver or processor to the "LINE IN" terminal on your PC SUB WL subwoofer. (See wired setup connection instructions.)

5. Low-Pass Frequency Control: If using the crossover setting in your A/V receiver or processor, set this control to "LFE" (Low-Frequency Effects). If using the sub's internal crossover, choose the setting that sounds best and matches the low-frequency cutoff of your main speakers. It may take some experimentation to find the best sound for your room and your equipment.

6. Phase Control: This adjustment matches the phase - the in and out movement of speaker cones - to that of your main speakers. Adjust this control by listening to music with bass content. The setting is correct when the bass sounds the fullest.

7. Gain Control: This adjustment increases or decreases the power, and thus volume, of the PC SUB WL. As with the Phase Control and the Low-Pass Frequency Control, it may take some experimentation to find the best sound for your system.

[VIBRATION ISOLATION PADS]

Included with your PC SUB-WL are a set of four (4) gray disks with an adhesive backing. The Vibration Isolation Pads should be used whenever your subwoofer is installed on any hard flooring surface. These pads prevent the subwoofer from moving against the floor when played at high levels. To use the pads, simply peel off the paper backing from the four disks and apply one pad to the bottom of each of the rubber feet of the subwoofer.

[CARING FOR YOUR PHASE TECHNOLOGY SPEAKER]

All Phase Technology speakers are finished with a high degree of craftsmanship in either hand polished paint or vinyl laminates. We recommend using a lint-free rag with a small amount of glass cleaner to maintain the long-lasting beauty of the finish. Avoid products containing silicones, oils, oil derivatives, or solvents. Enclosures finished in vinyl laminates may be cleaned with a damp cloth as necessary.

[MAINTENANCE AND SERVICE]

Because of Phase Technology's uncompromising quality control programs, it's unlikely that your speakers will ever need service if connected and used as outlined in this Owners' Manual. In the unlikely event that a problem does occur, please contact your Phase Technology dealer. Your dealer has the necessary factory-authorized parts and trained technicians to quickly restore your speaker to its original performance specifications.

[TROUBLESHOOTING]

NO SOUND

1. Verify that all components are plugged in and turned on.
2. Check all speaker wires and cables for loose connections.
3. Check to see if you have selected the proper source on your amplifier.

VOICES DO NOT APPEAR TO COME FROM BETWEEN THE SPEAKERS / BASS RESPONSE IS WEAK

1. Verify that all speaker connections from the amplifier to the speakers are running PLUS+ to PLUS+ and MINUS- to MINUS-.
2. Check to see if there are any furnishings or plants that may be blocking the output of a speaker.

SOUND, BUT NO BASS (MOST LIKELY IN SYSTEMS WITH A SUBWOOFER)

1. Verify that the subwoofer is plugged into an AC outlet and power is turned on.

2. Check that the speaker wire / cable going from the amplifier/receiver to the subwoofer is securely fastened.

3. Check the volume control of the subwoofer.
4. Refer to your amplifier/receiver manual to make sure you have adjusted its bass output properly.

MUDDY OR BOOMY BASS

1. Check the volume control for the subwoofer. Excess volume can cause speakers to sound distorted and unnatural.
2. Try adjusting the crossover control on the subwoofer or the subwoofer setup on your receiver to a slightly lower frequency (example: reduce from 120 Hz to 80 or 60 Hz).
3. If the subwoofer or full size speaker is close to a corner, side or back wall, try moving it away from the wall.
4. Bookshelf speakers placed in a semi-enclosed space or cabinet can artificially emphasize bass output. Reduce the bass control on your amplifier or move the speakers to the front of the cabinet. Alternatively, reposition the speakers to a more open location.

DISTORTED SOUND FROM THE SPEAKERS

1. This problem is usually caused by setting the volume control too high. Reduce the amplifier/receiver volume to a lower level.
2. If noise and distortion are audible at higher volume levels, your amplifier may not be powerful enough. Consider upgrading to a unit with higher power.

NOTE: Remember, even though your Phase Technology speakers can handle considerable power levels, ANY speaker if used improperly can be damaged. Consult your Phase Technology dealer for assistance in choosing a new amplifier or receiver.
