Spectral CTA2-V2 - Troubleshooting: Surround Sound and Balance; Surround Sound and Balance Adjustments; Voice Clarity and Bass Issues

66
The balance is wrong (location is
not central)
In Surround mode there is little or
no surround sound
In Surround mode the voices are
hard to understand
The sound system has little or no
low bass
1. The volume adjustment of the satellite speakers is wrongly set
or the listening spot is not central
1. The Play mode is set on “stereo” or “wide”
2. The listening spot is not central enough
3. The source only supplies a 2-channel signal
4. The sound system is set to 4.1/5.1 mode
1. During recording (BD or DVD) the voices were mixed between
the right and left channels
2. The sound system is in 5.1 mode
1. Listening at a (very) low volume
2. The output for an external subwoofer is activated but no
subwoofer has been connected or is operating
3. The sound system is in a poor acoustic location
4. Equalisers have been set in the “Room Comp” menu (volume
level increase)
1. In the Loudspeaker Menu use (m => Speaker Setup =>
Level Trim) to set the correct volume levels and (m =>
Speaker Setup => Speaker Distance) to set the correct
distances
1. Set Play modes to “surround 1” or “surround 2”
2. In the Loudspeaker Menu use (m => Speaker Setup =>
Level Trim) to set the correct volume levels and (m =>
Speaker Setup => Speaker Distance) to set the correct
distances to the listening spot
3. To achieve optimal sound in the room the sound
system requires a multi-channel data stream. In this
case the RC displays “Virtual Dolby Digital” or “Virtual
DTS”. All other displays (e.g. “Virtual Dolby PLII) mean
that it is not a multi-channel data stream, which leads
to less of a surround sound impression
4. Set the system to a 2.1 mode with Virtual surround-
mode at “System Preset” (m => System Setup =>
factory setup => System Preset)
1. Select “surround 2“ as Play mode
2. Set the system to a 2.1 or 4.1 mode at “System Preset”
(m => System Setup => factory setup => System
Preset)
1. Set “Bass expand” (m => Speaker Setup => Bass expand)
to “low” or “high”
2. Deactivate the output for an external subwoofer at
“Sub Output” (m => System Menu => Sub Output) or
connect it to an operational external subwoofer using
Sub-Out
3. Where possible, set up the system in a dierent position
(e.g. closer to the wall)
4. Correct or delete the settings for the room adjustment
(m => Speaker Menu => Room Comp => subwoofer)
