Adjust the time difference between the center and front speakers to create a time delay between 1 and 5 milliseconds, producing a more accurate audio effect. Adjust the time difference between the rear and front speakers to create a time delay between 3 and 15 milliseconds, producing a more accurate audio effect. Normal Output Audio signal output at 48kHz Return to previous menu. NOTE: When Down Sampling is ON, the audio output signal will be converted to 48kHz. When Down Sampling is OFF, the original sampling frequency is preserved. SPK CONFIG Menu To change speaker settings for 2-channel mode, use the >> or >| button (19) on remote control or the > button on the joystick (9) to move to the speaker settings on the right. Speaker Selection Selecting LARGE for the multi-channel speaker option will give a full range output. Selecting SMALL for the multichannel speaker option will activate a high pass filter whose crossover is dependent upon the sub-woofer low pass filter frequency. For example, if the subwoofer low pass filter is set to 80Hz, then the high pass SMALL speaker crossover will be set to 90Hz. Low pass High pass 80Hz 90Hz 120Hz 135Hz 160Hz 180Hz Refer to Table 16 when selecting speaker options for each mode.

Surround Sound Dolby Digital Dolby Digital is the reigning standard for surround sound technology in general and 5.1-channel surround sound in particular. Dolby Digital is a highly sophisticated and versatile audio encoding/decoding technology. Dolby Digital technology can transmit mono, stereo (two-channel), or up to 5.1-channel surround sound. Pro-Logic II Pro-Logic II is a dramatically improved matrix surround system based on the original Dolby Pro Logic system. ProLogic II offers two full-range stereo surround channels, more sophisticated steering logic, high channel separation and an exceptionally stable sound field. Dolby Pro-Logic II uses simple servo circuits used to derive the five audio channels. Unlike other "Surround Effects" found in other consumer equipment, Dolby Pro-Logic II does not introduce unwanted delays, echoes, reverberations or tonal colorations. 25
