7.1 AMP 入 5.1 signal 時
部 AMP show DTS, 只係著左 L, C, R, SR, SL, LEF 既燈, 但係發覺原來後面 4 隻 surround 都會發聲, 請問係唔係正常? 定係有野要 set?小弟用 LX72 + HTPC + HDMI direct input.

Using surround back channel processing
‧ Default setting: SBch ON
With 5.1 encoded sources, a surround back
channel will be generated, but the material may sound
better in the 5.1 format for which it was originally
encoded (in which case, you can simply switch surround
back channel processing off).
1 Set the operation selector switch to RCV.
2 Press SBch repeatedly to cycle the surround back
channel options.
Each press cycles through the options as follows:
‧ SBch ON – 6.1 or 7.1 decoding is always used (for
example, a surround back channel will be generated
for 5.1 encoded material)
‧ SBch AUTO – Automatically switches to 6.1 or 7.1
decoding for 6.1 encoded sources (for example,
Dolby Digital EX or DTS-ES)
‧ SBch OFF – No sound is output from the surround
back speakers 唔該晒 C Hing! {:1_351:}
