For this reason it is advisable to choose loudspeakers which are similar in power handling and performance capability to those of the front channels. Dolby Digital however is a full range system, with two independent surround channels and with dynamics equal to that of the front channels. Installing surround speakers will greatly enhance the surround experience as these add considerably to the overall “ambience”.ĭolby Pro Logic encoded material is deliberately limited in dynamic range and frequency bandwidth for the surround channel and thus only requires speakers of far lesser specification compared to the front channels. Ideally it should be the same type as the left and right speakers. For best results, you should consider using a centre speaker. Having the sound spread across three front speakers also stabilizes the stereo image, making the usable listening area much bigger. Using a separate centre channel speaker will allow the dialogue to cut through even the biggest sound effects and musical scores.

Audio signals intended for speakers set to the OFF position are redirected to the main speakers. The OFF mode is used when the speaker is inactive. The ON mode is used when the speaker is active and receives the audio information intended. The SMALL mode is used when the speaker is not capable of reproducing the deepest bass portion of the audio frequency 20Hz to 100Hz. The LARGE mode is used when the speaker is full range and capable of reproducing the entire audible frequency spectrum 20Hz to 20kHz. The four modes available to the T742’s setup are: LARGE or SMALL and ON or OFF. If in the future you add or change speakers, this setup procedure should be repeated. Press the SET UP button again to exit the SET UP MENU. Press the SET UP button again to exit SPEAKER SETTING MENU. Now rotate the VOLUME/SETUP knob until EXIT appears in the display window. Each press of the SET UP button will change the setting for that speaker: SUB (subwoofer) can be set to ON, OFF. Press the SET UP button again to change the setting. Now rotate the VOLUME/SETUP knob until SUB ON (current setting for the Subwoofer) appears in the display window. Each press of the SET UP button will change the setting for that speaker: REAR (Surround Speakers) can be set to LAR, SMA or OFF. Press the SET UP button again to change the size. Now rotate the VOLUME/SETUP knob until REAR LAR (current setting for the SURROUND speakers) appears in the display window.
