2. Distance
The speaker distance parameters sets delay control for the corresponding
audio channel. This delay is used to compensate for the audio propagation

from the listening position.
Speaker distance delay is only applied if the player is decoding multi-channel
audio. If you use bitstream audio output to your A/V receiver, the bitstream
audio is not adjusted for speaker distance delay.

For example, in the above diagram, measure the distance (in feet) from the
primary listening position to the Front Left or Front Right speaker. Your Front
Right and Left speakers must be the same distance from the listener. Enter
the distance of the Front speakers (1. in the above picture) into the "Speaker

Next, measure the distance (in feet) from the Center speaker (2) 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 the center, subwoofer and surround

Notes:
– The distance between the surround speakers and the listener must be
shorter than or equal to that between the front speakers and the listener.

Changes to the distance of one speaker will automatically change the other
speaker of the pair.
3. Trim
The speaker trim level parameters sets the volume of each individual channel.
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.
Notes:
– Increasing 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.
– Each speaker can be set to independent trim levels and there is no linked
pair limitation.
Other audio processing settings
1. Crossover frequency

frequencies are not passed to the speakers to reduce possible distortion,
bass frequencies will instead be redirected to the subwoofer.
40Hz / 50Hz / 60Hz / 70Hz / 80Hz / 90Hz / 100Hz / 110Hz / 120Hz / 130Hz /
140Hz / 150Hz / 160Hz / 200Hz / 250Hz
– These are the available crossover
frequencies. You can press the
/
buttons and the Enter buttons to select
it. This option applies to all speakers (center, front, surround, and surround
back speakers). By default the crossover frequency is 80Hz.
2. Dynamic range control
Sets the Dynamic Range Compression (DRC). DRC can smooth out the sonic
peaks and valleys common with wide-range digital audio. Enabling DRC may

Note:
Dynamic Range Compression is applied to the analogue audio output
and digital audio outputs (HDMI, Coaxial and Optical) when the audio format
is set to PCM.
3. DTS Neo:6 mode
Enables DTS Neo:6 audio processing and select the listening mode. DTS
Neo:6 is a digital signal processing that can expand the original stereo source
to 7.0 (L, R, C, LS, RS, LR, RR) or 7.1 (with Bass Management) surround.

– Enables DTS Neo:6 audio processing for stereo music sources.
Cinema
– Enables DTS Neo:6 audio processing for digital TV box or stereo
movie sources.

5. A/V Sync
Allows you to add a slight delay to the audio so it is synchronized to the
video. You may use the
/
buttons on the remote to decrease/increase the
audio delay. The delay can be adjusted in 10ms steps and within the range
of -100ms to +200ms. The delayed time will be applied to all output terminals
including HDMI 1 and 2, Coaxial, Optical, and 7.1 outputs.

used for each output. Please adjust this setting based on the actual output
terminal in use.
– The negative adjustment values are for cancelling out the audio delay that
the player automatically applies. Depending on the video source and the
time it takes to process the video, the main decoder chip automatically
applies an audio delay in order to optimize audio video synchronization.
The negative manual settings reduce the automatic audio delay, while the
positive manual settings apply additional delay. Any negative value setting
beyond the player's automatic delay will be treated as completely cancelling
the automatic delay. For example, if the "A/V Sync" value is manually set
to -100ms and for the current video source the player applies a 70ms

cancelled and the audio is not delayed at all. It is not possible to put audio
ahead of video using this setting.
– For content sent through HDMI IN, the "A/V Sync" adjustment only works
with positive values.
