The b) situation can be useful in situations, where the L, R speakers can handle
deep bass information and extra bass is required.
If the L and R speakers are not so well suited for the lowest frequencies, then chose
a), eventually with lowest 60Hz cross over frequency.
Further the Subwoofer – max bass ON can be selected in the Dolby Digital and DTS
mode if extra bass is required.
The Subwoofer – max bass setting will be stored in the memory bank and can
therefore be set individually for each surround mode.
6.2 Inputs
Assignment of socket for each input can be selected in this menu as previously
described in section 1.
6.3 Noise
If different speakers are used or the distance from the listening position to each
speaker is different, the perceived sound level at the listening position from each
speaker will change. By selecting the NOISE option, a noise signal is sent to each
activated speaker. The noise signal will cycle around and the user should set the
level for each speaker to obtain equal sound level at the listening position.
A sound pressure level meter can be used if required - use the "C" weighted setting,
and hold the meter away from the body.
Exit from noise test: push “
⇐” or “>VOL” keys.
6.4 Crossover frequency
A very useful feature is the Cross frequency setting. If a speaker is selected as
small, the low frequency content is sent to the Subwoofer and/or L/R speakers. The
corresponding crossover frequency is selected under the config.cross freq menu.
Small surround speakers could be selected as high as 120Hz, but larger speaker
should be 60Hz.
6.5 Extended Surround
In this menu you can enable DTS ES 6.1 Discrete + Matrix and DTS 6.1 Compatible.
Please refer to “Surround mode” section for explanations.
6.6 Dynamic range compression
When playing in a noisy environment, it may be desirable to boost the low level
signals, to be able to hear the low level signals at realistic average sound levels (e.g.
the sound of the leave rustling in the wind). Further the low level boost can increase
understanding of speech, especially in noisy environments.
It may also be desirable to limit the peak sound level, not to disturb neighbours at
night.
