PaCKaGe COntents 1x Subwoofer 1x Grille 1x Quick Start Guide PLaCeMent When using subwoofers within the limited confines of a typical home theater room, the reflections, standing waves, and resonant absorbers within the room will create peaks and dips in the bass response that can vary greatly depending on where the listeners are located in the room - a listener seated in one location may hear an over abundance of bass created by a response peak at the location, while another listener only a few feet away may hear far less bass due to a response dip at that location. The locations of subwoofers within the room (along with the room’s dimensions) also have a profound effect on the creation of these bass response peaks and dips. Careful subwoofer placement alone cannot compensate for all bass response peaks and dips throughout a room, but careful subwoofer placement can eliminate or significantly reduce the largest response dips. It is important to reduce response dips throughout the room as much as possible via proper subwoofer placement because equalization cannot be used to compensate for large response dips. For example, using equalization in an attempt to restore a 13dB response dip requires that the subwoofer amplifier deliver 20 times the power at that frequency. This can quickly overdrive the subwoofer amplifier into clipping, which will significantly degrade audio quality. In almost any room, placing the subwoofers in corners will produce the fewest large bass response dips and will also produce the largest bass response peaks. We strongly recommend that you install multiple subwoofers regardless of the room size. A single subwoofer will result in the least consistent bass performance throughout the room. Using multiple subwoofers can cancel some room modes at the various listening locations, resulting in much more consistent low-frequency sound quality throughout the listening area. It is often impossible to locate a single subwoofer such that large response dips, which cannot be corrected via equalization, are not present. The use of two or more properly placed subwoofers almost always eliminates such response dips.4 English Since wall construction is almost never perfectly identical on opposite walls, common formulas such as placing the subwoofers at ¼ points rarely work in practice. The best solution is to make high-resolution measurements from the primary listening area while experimenting with speaker placement. Placing a subwoofer at the listening position and measuring it from the potential installation positions around the room - using acoustic reciprocity - can help speed finding the best position(s). Measurement at the best positions in this manner will produce the measurements with the fewest and smallest peaks and dips in the response.

PLACING TWO SUBWOOFERS

PLACING FOUR SUBWOOFERS

Video Screen COnneCtIOns Speakers and electronics have corresponding (+) and (–) terminals. Most manufacturers of speakers and electronics, including JBL, use red to denote the (+) terminal and black for the (–) terminal. It is important to connect both terminals identically: (+) on the speaker to (+) on the amplifier, and (–) on the speaker to (–) on the amplifier. Wiring“out of phase” results in thin sound, weak bass, and a poor stereo image. With the advent of multichannel surround sound systems, connecting all of the speakers in your system with the correct polarity remains equally important in order to preserve the proper ambience and directionality of the program material. The JBL Synthesis SSW-1 subwoofer has dual inputs, with the input for each woofer directly behind it on the rear of the enclosure. For driving the SSW-1 from a single amplifier channel, the (+) terminal of the amplifier should connect to both (+) input terminals of the SSW-1. The (–) terminal of the amplifier should be connected to both (–) terminals of the SSW-1. In this wiring configuration, the amplifier will be presented with a 4 Ohm load. Alternatively, two equal amplifier channels can be used, one for each woofer input. Each amplifier (+) terminal should connect to one of the woofer input (+) terminals. Each amplifier (–) terminal should connect to the SSW-1 (–) terminal of the terminal set that is connected to the same amplifier channel's (+) terminal. If the bass response seems low, there may be a phase problem between the two drivers, with the sound waves from the two woofers canceling each other out. Double-check your wiring to make sure both woofers in a single SSW-1 have their (+) terminal connected to the appropriate amplifier (+) terminal and their (–) terminal connected to the appropriate amplifier (–) terminal. If two SSW-1 subwoofers are used, the wires for both speakers should be the same length. If the bass response seems low, there may be a phase problem between the subwoofers, with the sound waves from the two subwoofers canceling each other out. If the bass response seems low, try inverting the polarity on one subwoofer – i.e., connect the (+) terminal on the amplifier to the (–) terminal on the speaker, and the (–) terminal on the amplifier to the (+) terminal on the speaker. To use the binding-post speaker terminals on the terminal cup located behind the SSW-1 subwoofer, unscrew the colored knob until the pass-through hole in the center post is visible under the knob. Insert the bare end of the wire through this hole, then screw the knob down until the connection is tight. Spade connectors can be slid around the post before tightening the knob if those are used. The hole in the center of each knob is intended for use with banana- type connectors. Making sure to observe the correct polarity. The wire from the amplifier’s negative (-) terminal is to be connected to the negative (-) or black terminal on the terminal cup, and the amplifier’s positive (+) terminal is to be connected the positive (+) or red terminal on the terminal cup. Since the SSW-1 is a passive loudspeaker, only speaker-level connections are available. The SSW-1 subwoofer is specifically designed for use in conjunction with the JBL

Synthesis SDA amplifiers. It is optimized to offer the best dynamics and frequency response with the use of the JBL Pro DSi MA4-D amplifier, which is specially designed to use the proprietary SSW-1 tuning file and drive the signature reactive load impedance of the SSW-1. When using a different SDA amplifier with the SSW-1, contact your certified Synthesis installer for correct adjustment and loading of the SSW-1 tuning file. The SSW-1 is capable of running off of two JBL Pro DSi MA4-D channels in bridged mode. Connect your main receiver or processor’s line-level subwoofer output to the line-level input on your subwoofer amplifier. When using two or more subwoofers, use the correct number of amplifier channels (these can be mono-block or multi- channel amplifiers) each connected to the appropriate output on your processor or receiver. Then connect the positive and negative terminals for each amplifier channel to a single SSW-1 subwoofer system.6 English USING ONE SSW-1 SUBWOOFER WITH A SINGLE AMPLIFIER CHANNEL Receiver/Processor Subwoofer Out Line-Level InputsSpeaker-Level Outputs Amplifier SSW-1 Back Box USING ONE SSW-1 SUBWOOFER WITH TWO AMPLIFIER CHANNELS
