AUDIO SURROUND OFF Use this for normal stereo/mono broadcasts. MATRIX SURROUND Listener is surrounded by many sound sources such as a sporting event, etc. NOTE: Some TV systems do not transmit optimum audio channel separation which can reduce the effectiveness of the MATRIX SURROUND function. HALL SURROUND Resonant sound - Listener has the feeling of being in a concert hall. PRO LOGIC Dolby Pro Logic provides four separate sound channels: left, center, right and surround. For a properly encoded program marked the center sound channel contains the dialogue for the program viewed. The left and right channels produce sound effect that will match the action on the TV screen. For example, Dolby Pro Logic will enhance the effect of a car viewed driving from the left side of the TV screen to the right side. The surround channel (speakers) are placed behind the viewing area to add additional spatial sound effects. To fully benefit from Dolby Pro Logic Surround, it is recommended that the surround speaker system be complete as shown on page 15. Use the CURSOR buttons to select the surround function. MODE Can be set to 3CH LOGIC or PRO LOGIC. When 3CH LOGIC is set, the CENTER MODE will automatically be set to NORMAL. 3CH Logic prevents loss of the surround channel sound by splitting it between the left and right speakers from a separate audio amplifier. CENTER MODE This can be set to NORMAL or PHANTOM when using the MODE: PRO LOGIC. PHANTOM center mode prevents loss of center channel sound by splitting it equally to the left and right TV speakers. TEST TONE A test sound is generated allowing the listener to balance volume from each channel. Adjust the volume levels until all channels are equal. Use the CURSOR buttons to select and adjust VOLUME and BALANCE. Press MENU to exit. NOTE: The BALANCE in TEST TONE is the same as the BALANCE in 52
