DTS LFE Settings
The Cinema Rhapsody permits the adjustment of the DTS LFE level prior to the summing of the bass
information from all speakers that are set to small. This LFE level adjustment applies only to DTS
decoding modes. When listening to DTS encoded software, you may notice a preponderance of bass
as compared to non-DTS material. Based on laboratory testing, ADA has determined that some DTS
material has an increased LFE level of 10dB. As such, the Cinema Rhapsody Mach II offers a setup
feature that permits you to minimize the LFE signal from DTS encoded material. With this feature
enabled, as you change between DTS and non-DTS decoding, you will not need to make on-going
adjustments to your systems bass and subwoofer settings.
The Out of the Box setup for this feature is turned off (FLAT). In order for this setting to take effect, you
must first Enable the feature as outlined in the first section on this page, DTS LFE Adjustment Enable.
You can then proceed with the second section on this page, DTS LFE Adjustment. The range of this
adjustment is from -20dB to 0db. The Out of the Box configuration for DTS LFE Adjustment is -10dB.
If you are planning on making an adjustment to the DTS LFE level, ADA recommends doing so while
playing a DTS encoded source with the Cinema Rhapsody Mach II in a DTS mode. While enabling
this feature and setting the level to 0dB are in effect the same as setting the Enable option from on
(ATTN) to off (FLAT), the concept of offering a single on/off function, without changing the underlying
level, permits the creation of on/off buttons on controls and touch screens. As such, the actual level
control remains untouched.
DTS LFE Adjustment Enable
To engage the DTS LFE Attenuation Adjustment:
1 Turn the Mode knob clockwise until the display’s second line reads SETUP MENU and then
press the Mode knob.
2 Turn the Mode knob clockwise until the display’s second line reads PRO SETUP and then
press the Mode knob.
3 Turn the Mode knob clockwise until the display’s second line reads DTS LFE ENBL and press
the Mode knob.
4 Turn the Mode knob so that the display’s second line reads DTS LFE ATTN if you wish this
filter to be on. To turn this feature off, turn the Mode kob so that the display reads DTS LFE
FLAT.
5 If you selected DTS LFE ATTN, when DTS decoding takes place, the LFE will be lowered by
10dB (Out of the Box setting) prior to the summing of bass information from all the speakers
that are set to small. To adjust the actual DTS LFE level, proceed with the steps below. To
completely exit the setup menu, turn the Volume knob.
DTS LFE Adjustment
The Out of the Box configuration for DTS LFE Adjustment is -10dB. To change this setting:
6 Turn the Mode knob counterclockwise until the display’s second line reads DTS LFE ADJ and
press the Mode knob.
7 Turn the Mode knob to set the desired level for the LFE and then press the Mode knob. Please
note, that you may wish to be listening to a DTS source while making this adjustment.
8 Press the Mode knob to continue with other Pro Setup options. To completely exit the setup
menu, turn the Volume knob.
