[. . . ] ® Designed to Entertain. TM AVR 144 AUDIO/VIDEO RECEIVER OWNER'S MANUAL SAFETY INFORMATION CAUTION RISK OF ELECTRIC SHOCK DO NOT OPEN 1. All the safety and operating instructions should be read before the product is operated. The safety and operating instructions should be retained for future reference. All warnings on the product and in the operating instructions should be adhered to. [. . . ] With proper bass management, the AVR 144 divides the source signal at a crossover point. All information above the crossover point is played through the satellite speaker (front left/right, center or surround left/right), and all information below the crossover point is played through the subwoofer. This enables each loudspeaker in your system to perform at its best, delivering an enjoyable sound experience. Figure 33 ­ Manual Setup Menu Screen The Manual Setup menu is the gateway to four submenus: Speaker Size, Speaker X-Over, Delay Adjust and Channel Adjust. Speaker Size Menu Press the Set Button to display the Speaker Size submenu. See Figure 34. Step Two ­ Measure Speaker Distances Ideally, all of your speakers were placed in a circle, each at the same distance from the listening position. However, your room may not be ideal, and you may have had to place some speakers a little further away than others. This could affect the overall sound of the receiver, as sounds that are supposed to arrive simultaneously from different speakers blur, due to different arrival times. Fortunately, the AVR 144 has a delay adjustment that enables the receiver to compensate for real-world speaker placements. Before you begin making adjustments, measure the distance from each speaker to the listening position, and note it in the worksheets in the appendix. Even if all of your speakers are the same distance from the listening position, you should enter your speaker distances. Figure 34 ­ Speaker Size Menu Screen Step Three ­ Manual Setup Menu Now you are ready to program these adjustments into the receiver. It's best to sit in the usual listening position and make the room as quiet as possible. Don't worry if you make a mistake; you can always go back and change these settings. With the receiver and video display turned on, press the OSD Button on the remote. Use the ¤ Button on the remote to move the cursor to the MANUAL SETUP line, and press the Set Button to display the Manual Setup menu. See Figure 33. The Speaker Size menu lists each of the speaker groups. You will be programming the correct setting for each group, indicating how many speakers are in your system and what their capabilities are, based on the information you obtained in Step One ­ Determine Speaker Size. Each of the main speaker groups can be set to one of three settings: LARGE, SMALL or NONE. These settings don't refer to the physical size of the speaker, but rather to the size of the frequency range of each speaker. If the lower number of the frequency response for your speakers is less than 100Hz, choose the LARGE setting. If you don't have a speaker connected to that position, choose NONE. As you can see, the system requires you to use both speakers in a pair. For example, you can't connect just a front left speaker without a right speaker, or just a right surround (rear) speaker without a left one. However, you can connect only the front speakers, or both front and surround speakers without a center, or the front left/right and center speakers without any surrounds. 27 INITIAL SETUP LEFT/RIGHT: This line tells the AVR 144 the capabilities of your front left and right speakers.
