General Connections Caution: Prior to connecting the SA-2 to your system, it is important that all AC power connections to associated components (receivers, amplifiers, pre-amplifiers, processors, etc.) are either unplugged or turned off.

tings on the same track. Do not attempt to evaluate the best sound while standing above the subwoofer or amplifier , as the sound at the listening position will be significantly different. Subwoofer V olume Control The SA-2’s front p anel VOLUME CONTROL allows you to adjust the volume of the subwoofer relative to the rest of the system.
This method of connection allows your main speakers to receive the full-range audio signal (no high-pass filtering), and the subwoofer to be utilized for low bass extension only . 1) Y our L & R speakers are connected directly from your amplifier / receiver .
This method allows your main speakers to receive a high-pass filtered signal (not full range), and the subwoofer to be utilized for low- to mid-bass reproduction.
This method of connection is recommended if you have a receiver with no line level preamplifier output of any sort and you want your L & R speakers to receive a high-pass filtered signal. The SA-2 may be connected to the system at speaker level between the receiver and the speakers.
This method of connection is recommended when you have a receiver with no line level preamplifier output of any sort and you want to run your speakers full range (no high-pass filtering). If your receiver features two set s of speaker output terminals (“S peaker A” and “S peaker B”), you may use “S peaker B” to connect the SA-2.
Fine T uning the Subwoofer The frequency chart below lists some terms commonly used to describe dif ferent bands of the frequency spectrum. The key to good subwoofer / speaker integration is repeated listening, followed by small re-adjustments of the subwoofer controls.
Multiple Subwoofer Configurations: Using two SW2Si subwoofers While the addition of a powered subwoofer system results in significant improvement s to an audio or home theater system, there are some potential drawbacks to the use of a single subwoofer in certain rooms.
This connection method routes the full-range line-level signal from the preamplifier through the SA-2, which passes on a high-pass filtered signal to the main amplifier and powers the subwoofer sections of the speakers directly with a low-pass filtered signal.
This connection method results in sending a full-range line-level signal to both the main amplifier and the SA-2. If you have a separate preamplifier that features two sets of line output s, each set is connected to one amplifier . If the preamplifier features only one set of line outputs, use “Y”-adaptors to split the signal.
This connection method may be employed if your receiver has no line-level preamplifier output. The speakers and the SA-2 are con- nected in parallel of f the receiver ’s speaker output terminals.
Recommended biamplification settings: 1) SUBWOOFER PHASE: 0° . If the main amplifier inverts phase, use 180°. If you are unsure about this, select the setting that result s in higher bass output with the volume control unchanged.
T roubleshooting If the amplifier fails to operate when the Power Switch is turned on, check the power cord and all the input and output connections thoroughly . If the front panel st atus LED is red, the unit is in “protect” mode. This could be caused by incorrect wiring, short circuits, or excessive volume.
