[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
