A typical 7.1-channel speaker layout and their speaker distance measurements are displayed as below:

	FL	C	FR
	SW
Speaker Icons:		2	Distances:
			1
FL - Front Left			1 - Listener to Front
			2 - Listener to Center
FR - Front Right
			3 - Listener to Surround Left
C - Center
	SL		SR
SW - Subwoofer
SL - Surround Left	3
SR - Surround Right	SBL	SBR
SBL - Surround Back Left
SBR - Surround Back Right

In the above diagram, measure the distance (in feet) from the primary listening position to the Front Left or Front Right Speaker. Enter the distance of the Front Speakers ( in the above picture) into the Speaker Configuration menu.

Next, measure the distance (in feet) from center speaker () to the listening position. Move the cursor to highlight the Center speaker in the Channel Delay setup page, and enter the distance (as close as possible) in feet. Repeat for each speaker in the system (Center, Surround Left, Surround Right, Surround Back Left, Surround Back Right and Subwoofer) as available. The player will insert appropriate delay to make sure sound waves from different speakers arrive at the listener at the same time.

It is possible to independently set distances for each speaker. Speaker distances can be set to the actual spatial distance of the speakers.

If the channel delay settings cannot match your speaker configuration, please set all distances to the same and use your receiver/amplifier to set the channel delay.

3.Trim: The speaker trim level parameters sets the volume of each individual channel. Channel trim is generally not required since most A/V receivers have the capability to adjust channel trim and compensate for speaker sensitivity differences. However, if your receiver does not have such functions (many receivers do not support channel trim for their multi-channel analog inputs), you may adjust channel trim through the player. For most accurate results, it is recommended that you use test tones from a calibration disc, such as Digital Video Essentials HD Basics, and a SPL (Sound Pressure Level) meter. The trim level can be set to +/- 10dB in 0.5dB increments.

NOTE

ξIncreasing the Trim Level above 0dB may result in distortion if the original audio level is already high. When this occurs the waveform becomes clipped and audible distortion can be heard. In this situation, it is necessary to reduce the Trim Level until the distortion is removed. When using the Trim Level for speakers, it is recommended that you set the least sensitive speaker’s Trim Level to 0dB, and set other speakers’ Trim Level to negative values.

ξThe Test Tone can be used in conjunction with the player’s trim control. Each speaker can be set to independent trim levels and there is no linked pair limitation.
