Automatic Power Circuitry: This feature activates your subwoofer whenever it senses a signal (any music source) coming from your amplifier. The same circuit will automatically shut power off to your subwoofer about ten minutes after you turn off your main amplifier. This means you may always leave your subwoofer’s power switch on.

Level Control: A precision level control is built into your subwoofer to enable volume adjustment of the bass frequencies. Set the level according to your personal preferences from significant bass response, as might be preferred in home theater listening, to the softer, more natural presence that might be the choice for enjoying musical programming.

Crossover Point Control: Phase Technology Powered Subwoofers also feature internal crossover networks designed to enable the subs to be acoustically matched to virtually any pair of full-range speakers.

The adjustable crossover control on the subwoofer’s back panel should be set near the low-frequency roll-off point of our front speakers. The specifications listed for your main speakers will generally specify this point as a “-3 dB” frequency. It’s important to trust your ears when setting this control. Too high a setting will exaggerate bass response, while too low a setting could produce weak bass.

When using low-level connections on certain Phase Technology premium subwoofers, the network controls both the low-pass and high-pass crossover points with matched slopes for uniform frequency response. (Please refer to the specifications included with your subwoofer.)

Servo Control: This innovative feature protects your Phase Technology powered subwoofer from being over-driven and, thus, producing unnecessary distortion. It automatically limits the subwoofer’s loudness and excessive movement of the speaker cone in the unlikely event that the demands of your program material exceed the capacity of the subwoofer’s internal amplifier and speaker.

Phase Control: This feature enables setting the subwoofer’s phase at two positions, which may be labeled “+” or “-” or “0੦” or “180੦.” We suggest starting with the control at the “+” or “0੦” position with someone else adjusting the control while you listen from where you normally sit. One of the settings will produce a fuller, more robust bass response, and the Phase Control should be left in that position.

SPECIAL PRODUCT FEATURES

Adjusting Variable-Axis, Soft-Dome Tweeters

Some Phase Technology speakers feature the company’s acclaimed variable-axis soft-dome tweeter (refer to the model specifications included with your speakers) offering even greater latitude in selecting speaker locations and listening positions.

This revolutionary tweeter can be adjusted by hand to direct the high frequencies towards a specific listening area for optimal tonal balance and channel separation. This enables owners of these Phase Technology models to place the speakers where they look or fit best and then aim the tweeter for best effect.

When adjusting these units, be careful to press on the outer rims only, avoiding contact with the center, or soft dome, of the speaker. A series of adjustments may be necessary to achieve the ideal clarity and smoothness of the high frequencies that the variable-axis soft-dome tweeter was designed to present.

Bi-Wired Connections

Some Phase Technology premium audiophile speakers are equipped for be-wiring, with four speaker terminals instead of two. This may enhance speaker performance by using an additional pair of speaker cables.

In order to bi-wire these speakers, remove the gold-plated strips between the speaker terminals and connect two
