25 SETUP, cont How to Adjust for Loudspeaker Size A Home Theater System can include a variety of Loud- speakers with various capabilities. The LARGE listing re- fers to the Loudspeakers capability for reproducing bass frequencies down to 35Hz within -3dB of the midrange fre- quencies. If a Loudspeaker can not reproduce bass frequen- cies down to 35Hz within -3dB of the midrange frequen- cies, it is considered SMALL. If you do not have a Subwoofer, you must have Front (Left and Right) Loud- speakers that are LARGE in order to hear the low frequen- cies below the Subwoofer Crossover Setting of 80Hz. If you are unsure as to the bass performance capabilities of your Loudspeakers, select the SMALL setting. 1. Press and hold the Front Panel SETUP Push-button ap- proximately three seconds to enter the Setup Mode. The word SETUP will appear on the MX134 Front Panel Alphanumeric Display and the MAIN SYSTEM SETUP Menu will appear on the Monitor/TV screen. Refer to figure 6 on page 23. 2. Using the Up or Down directional push-buttons, select Speaker Size on the On-Screen Menu, followed by the SELECT Push-button on the Remote Control. Refer to figure 8. Notes: The very first time the SPEAKER SIZE MENU is accessed, the factory default settings will be indicated. In the Speaker Size Menu Setting Options, the number after the name of Small or Large refers to quantity of Loudspeakers. If the setting for the Back Surround Loudspeaker is Small 1,only the Zone A Back Output Left Channel will have audio output. 3. Select the appropriate Loudspeaker location and type by using the Up or Down directional push-buttons to select first the menu item and then press the Left or Right directional push-buttons to change the cur- rent setting. Notes: When the Front Loudspeakers are set to Small, the options in the Speaker Size Setup Menu for the Center and Surround Loudspeakers are Small or None; the Subwoofer Loudspeaker will be set to the On position. If the Surround Loudspeakers are set to Small, the options in the Speaker Size Setup Menu for the Back Surrround Loudspeaker are Small 1(BSL), Small 2(THX) or None. When the Small 1 (BSL) setting is selected, the BACK Surround Right Channel ZONE A OUTPUT will be switched Off. 4. When all of the settings on the SPEAKER SIZE MENU agree with the Loudspeakers in your Home Theater System, perform the Sub Crossover and/or the MC Bass Mode adjustments below or if no adjustments are needed, then continue to the SPEAKER TIME DELAY Settings. If you do not wish to perform SPEAKER TIME DELAY adjustments at this time, select MAIN MENU from the menu. The MAIN SYSTEM SETUP Menu will reappear on the Monitor/TV screen and pro- ceed to the next step. 5. Select EXIT from the MAIN SYSTEM SETUP Menu. If you are satisfied with the changes that you may have made, select YES to save those changes or NO not to save them. The MX134 will then return to normal op- eration. Refer to figure 7 on page 25. Sub Crossover The MX134 incorporates a built-in Electronic Crossover. The Crossover will redirect all of the audio frequencies be- low the crossover frequency setting to the Subwoofer and all the frequencies above the setting to the appropriate re- maining Home Theater Loudspeakers. The default setting for the SUB CROSSOVER frequency setting is 80 Hz, which is the correct frequency for most Home Theater Loudspeaker Systems. Refer to figure 8 and perform the following steps to change the setting. 6. Using the Up or Down directional push-buttons, select SUB CROSSOVER from the Speaker Size On- Screen Menu, followed by pressing the Left or Right directional push-buttons to change the cross- over frequency to the desired setting.
