b) Select L and R (or L,R,C,SL,SR in Pro Logic) to be LARGE and then select
Subwoofer – max bass ON in the config.cross freq menu. Here, a full-range
accumulated mono signal of all the other channels will be sent to the subwoofer.
The implication of b) is that “double bass” is present in the system. That means the
user should consider choosing a lower gain setting for the subwoofer, e.g. –4 to –8
dB depending on the sensitivity of the subwoofer relative to the other speakers.
The b) situation is useful in situations where the L & R speakers can handle deep
bass information but extra bass is required.
If the L & R speakers are not well suited for the lowest frequencies, then choose a),
probably with not less than a 60Hz crossover frequency.
Furthermore, 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 can now 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 your body.
Exit from noise test: push “⇐” or “>VOL” keys.
6.4 Crossover frequency
A very useful feature is the crossover 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
speakers should be set at 60Hz.
6.5 Extended Surround
In this menu, you can enable DTS ES 6.1 Discrete, 6.1 Matrix and activate the side
channels. Please refer to the “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
