All instructions and information pertain to both systems. Note that the SA-350 amplifier only has one set of front mounted controls and one set of input/output connectors on the back and is designed to work with a single 8 SUB woofer module. [. . . ] For those of you who may have heard otherwise, the choice of Large or Small is not a matter of opinion, preference, taste, or based upon the phases of the moon. So please ignore all the free and helpful (and many times incorrect) advice and set'em to Small. In fact, the vast majority of speakers on the market today should be set to small. As a rule of thumb, if any satellite speaker in your system doesn't have a 10 inch diameter or larger woofer it most probably should be set to small, as far as Bass Management is concerned. System Setup and Operation Since this is an in-wall system we assume that you already have the woofer modules installed in your room as per the guidelines provided with the InWall Enclosure. Generally speaking, the closer the subwoofer is placed to a corner, the more and deeper the bass response you will hear. However, in some rooms, corner placement can produce too much bass or a "one note" boomy effect. Should you find this to be the case in your room after installation, the built in parametric EQ can be used to improve the situation. The LOW PASS Control When used with a complete THX Certified speaker system, the InWall Subwoofer System LOW PASS control should be set at 80Hz unless you are using a processor with its own built-in crossover. If your processor is THX certified or has a built-in crossover, set the subwoofer amplifier's LOW PASS control to the THX/EXT setting. All THX certified satellites has been optimized to work LOW PASS with an 80 Hz crossover point. If your Processor/Receiver has no internal crossover (a fairly rare occurrence these days) the subwoofer's crossover should be 50 150 used to optimize the performance of the THX / EXT system, by ensuring that the subwoofer and satellites produce a cohesive and well integrated sound "picture. " 80 The PHASE Control A subwoofer operating out of phase with the rest of the system won't provide optimum low frequency performance. Also, the correct subwoofer phase can enhance room acoustics. Since there is some variation in the industry regarding phase, a PHASE switch that will alter the phase of the subwoofer is provided on PHASE the amplifier. It has 4 positions (0°, 90°, 180°, 270°) for added flexibility. To set the PHASE control, 90 180 insert the supplied Atlantic Technology/Sencore 0 270 Test and Training CD in your CD/DVD player and select the broadband bass test tones on Tracks 22. Have someone sit in the prime listen- Higher crossover frequencies pass more bass but can quickly begin to sound boomy. They also make it easier to localize the subwoofer, which is highly undesirable. Higher crossover frequencies may be suitable, however, when using very small satellites that have no real Operation Instruction Manual 13 ing position to evaluate the sound. Pay particular attention to the deep bass as well as the transition of bass from the subwoofer to the satellite speakers. You can also listen to a musical source such as a CD or DVD, with strong bass content that spans the range from deep bass to mid bass (a well recorded jazz disc with someone playing a full stand up bass is always a good choice). It's usually best not to use a "one note" special effects track like a big explosion or dinosaur stomping to test the subwoofer. Experiment with the position of the PHASE control(s) to get the most extended bass and the best transition from sub to satellites. It should be obvious which is the correct setting. [. . . ] Pressing the MUTE button turns off the volume of the subwoofer. Pressing it again returns the volume to its previous setting. EQ1 EQ2 EQ3 Direct Access Connector Located on the rear panel, this port and the corresponding male plug (included and installed in the port) is for use with a hard wired remote control system using electronic or mechanical switching. To access the control functions use a normally open connection. Momentary closure will activate each function. [. . . ]
