>>Specifications >>Settings >>Listening Modes >>Playback Function to be made in "AccuEQ Room Calibration" in Initial Setup. Check in "Initial Setup" in the Basic Manual. • Depending on the source and current listening mode, not much sound may be produced by the surround speakers. Select another listening mode to see if sound is output. • If you are installing surround back speakers (for compatible models only), surround speakers are required. • A maximum of 5.1 ch playback is possible when BiAmping connection is used (for compatible models only). Further, make sure you remove the jumper bar on the speakers when using Bi-Amping connection. ˙ The subwoofer produces no sound • When you play source material that contains no information in the LFE channel, the subwoofer produces no sound. ˙ Noise can be heard • Using cable ties to bundle audio cables with power cords, speaker cables, etc. may degrade the audio performance, so refrain from doing it. • An audio cable may be picking up interference. Try repositioning your cables. ˙ The beginning of audio received by an HDMI IN cannot be heard • Since it takes longer to identify the format of an HDMI signal than it does for other digital audio signals, audio output may not start immediately. ˙ Sound suddenly reduces • When the temperature inside the unit exceeds a certain temperature for extended periods, the volume may be reduced automatically to protect the circuits. 60 Listening Modes • To enjoy digital surround playback, such as Dolby Digital, the audio signals need to pass through a connection via HDMI cable, digital coaxial cable, or digital optical cable. Audio output should be set to bitstream output on the connected Blu-ray Disc player or other device. • Press on the remote controller several times to switch the display of the main unit to check the input format. Check the following if the above does not fix the problem: ˙ Cannot select a desired listening mode • Depending on the connecting status of the speaker, some listening modes may not be selected. Check in "Selectable Listening Modes" in "Listening Modes" in the Advanced Manual. ˙ There is no sound with Dolby TrueHD, Dolby Atmos, and DTS-HD Master Audio (for compatible models only) • You need to connect surround back speakers or height speakers to enjoy Dolby Atmos. Furthermore, Dolby Atmos can only be enjoyed when the input signals are Dolby Atmos. • If you cannot output formats such as Dolby TrueHD, Dolby Atmos, or DTS-HD Master Audio according to the format of the source, in the Blu-ray Disc player settings try setting lBD video supplementary soundz (or reencode, secondary sound, video additional audio, etc.) to lOffz. Change the listening mode for each source after changing the setting to confirm. ˙ Cannot select Pure Audio mode (for compatible models only) • The Pure Audio mode cannot be selected while the Multi-zone feature (for compatible models only) is on. ˙ About DTS signals • With media that switches suddenly from DTS to PCM, PCM playback may not start immediately. In such cases, you should stop your player for about 3 seconds and then resume playback. >>Basic Manual Troubleshooting | Appendix • With some CD and LD players, you will not be able to playback DTS material properly even though your player is connected to a digital input on the unit. This is usually because the DTS bitstream has been processed (e.g., output level, sampling rate, or frequency response changed) and the unit does not recognize it as a genuine DTS signal. In such cases, you may hear noise. • Playing DTS program material, using the pause, fast forward, or fast reverse function on your player may produce a short audible noise. This is not a malfunction.
