Level Setup Menu
• You can adjust the speaker levels by pressing
the LEFT and RIGHT keys.
• The subwoofer level refers to the signal level
sent to the subwoofer.
• The LFE (Low Frequency Effects) level refers
to the level of the redirected bass from the
LFE channel to the large speakers in case
there is no subwoofer. The LFE channel is
the “0.1” of the 5.1 channel digital surround
signal. It is present only with Dolby Digital
and DTS 5.1 channel sources.
• The range of adjustment is from –10 dB to
+15 dB, except for the LFE channel which
you can adjust only from –10 dB to 0 dB.
• You can engage the noise signal by selecting
the Test signal and pressing either the LEFT
or RIGHT key. This will start the test signal
cycling through the channels exactly as when
you press TEST key (see above), but in this case
you will do level adjustment by using the LEFT
and RIGHT KEYS, or TRIM keys.
