SAFETY PRECAUTIONS Read this User’s Guide thoroughly before attempting to install and configure your Ultra Subwoofer. All the safety and operation instructions should be read before any operation of the component(s) begin. After successful installation and configuration of the Subwoofer, be sure to retain this manual in a safe place for future reference. All warnings on the Subwoofer and in this Operation Manual should be followed. Safety is a key component to a long lasting, trouble free installation.
To prevent electric shock, do not use this polarized plug with an extension cord, receptacle or other outlet unless the blades can be fully inserted to prevent blade exposure. Grounding or Polarization — Precautions should be taken so that the grounding or polarization means of the component is not defeated.
NEC (National Electrical Code) Standards A Note for the Cable Television (CATV) Installer This reminder is to call the CATV system installer’s attention to Article 820‐40 of the NEC that provides guidelines for proper grounding and in particular, specifies that the cable ground shall be connected to the grounding system of the building as close to the point of cable entry as practical.

Emotiva Ultra Subwoofers Overview and Features Ultra Subwoofers are designed to add dynamic, solid bass to your home theater and music listening experience, while maintaining accurate, extended frequency response. All Emotiva loudspeakers are extremely efficient, allowing you to maximize power and performance in any listening situation. The compact cabinet size makes the Ultra Subs an ideal choice for systems employing multiple subwoofer setups.
Unpacking Your Ultra Subwoofer All Emotiva Subwoofers are double boxed to survive the rigors of long distance shipping to assure you of undamaged delivery. The outer box may show wear and tear, but this is no cause for alarm. The outer box’s purpose is to protect the inner box. If the inner box looks heavily damaged or penetrated, and you are concerned about damage to the Subwoofer, please call Emotiva Technical Support at 877‐366‐8324 (877‐EMO‐Tech).
Component Descriptions and Diagram * 1. MDF laminated cabinet Critically braced for durability and damped to reduce resonance; it features a full one inch thick baffle 2. Rubber booted grill mounts Mounts hold low luster grills securely in place and prevent unwanted vibration. 3. Proprietary para‐aramid blend reinforced paper woofer and dust cap The high performance cone decreases unwanted resonances and acts like a rigid, nearly perfect moving piston at low frequencies.
Back Panel Controls Descriptions and Diagrams 1. XLR/Balanced Input Input for an XLR/Balanced connection. Connects to your preamplifier or processor subwoofer output with an XLR/Balanced cable. 2. RCA/Unbalanced Inputs Input for an RCA/Unbalanced connections. Connects to your preamplifier or processor subwoofer output with an RCA/Unbalanced cable.
6. Phase Adjustment Control Adjusts the phase of the subwoofer from 0 to 180 degrees, relative to the main speakers. A subwoofer in proper phase with the rest of the speakers in a system is well integrated with the overall soundstage, adding bass frequencies which seamlessly blend with the other speakers. An out of phase subwoofer will draw attention to itself by seeming to be disconnected from the overall soundstage, sometimes sounding detached or disconnected to the other system speakers.
Connection Considerations Ultra Series Subwoofers feature both balanced and unbalanced connections (page 10, points 1 & 2). XLR connections are balanced lines, and are designed to reject external noise (from power cables, EMI and RFI emissions, etc.) to a greater degree than standard RCA connections. If your preamplifier/processor is equipped with a balanced subwoofer output, it is recommended that you use an XLR/Balanced interconnect to assure the highest degree of noise immunity.
Using an Ultra Subwoofer in a Multi‐Channel System This diagram shows an Ultra Subwoofer connected to an UMC‐1 Audio‐Video Processor. An Emotiva XPA‐5 five channel amp is shown, powering the left, center, right and surround speakers. The balanced subwoofer output on the UMC‐1 (1.) bypasses the XPA‐5 amplifier and connects directly to the subwoofer (2). NOTE: Your Ultra Subwoofer has its own power amplifier, and does not need to be connected to another amplifier.
Placement Tips Where you place your subwoofer is as important as any of the volume or low pass settings. This is because the room itself, other gear, and even furniture can greatly change the way sound waves propagate in your listening area. Certain areas in your room may magnify the resonant low frequencies, and certain areas may minimize them. Walls, cabinets, shelves, and other furniture may produce unwanted ‘booming’ frequencies. Proximity is usually the issue in this case.
Using Low Pass Filters and Setting the Crossover Frequency Note: If your preamp/processor has its own Low Pass Filter/Crossover settings, it is recommended that you use them to control the crossover frequency on your subwoofer. Turn the Low Pass Filter switch to ‘BYPASS’ (page 10, point 3). This disengages all low pass/crossover controls on the subwoofer. If your preamplifier/processor does not have Low Pass Filter/Crossover controls, use the controls on the subwoofer.
Using Multiple Subwoofers in a Multi‐Channel System The compact size of Ultra Subwoofers make them ideal for being used in systems that employ multiple subwoofers. This is becoming more common in home theater environments. Action films and concerts, especially, can greatly benefit from a substantial subwoofer setup that easily and comfortably fills the room during demanding low end sequences.
Troubleshooting Guide Ultra Subwoofers are expertly designed and built to provide years of trouble‐free performance. Most problems that occur can usually be solved by checking your setup or making sure that the audio and video components connected to the amplifier are on and fully operational. The following information will help you deal with other common setup problems you may experience during normal use of your unit. If problems persist, contact Emotiva support for help.
Ground loop isolators are available for audio lines and video devices. If you need assistance, contact Emotiva. Although this is not always an ideal solution, the grounding differences between certain home entertainment components sometimes require ground loop isolators. This is the exception rather than the rule. Other Probable Causes of Noise • Speaker noise may also be caused by interference or noise on your AC line.
