Note: These adjustments work in the digitally processed Stereo and
Surround modes but not in 5.1 Direct mode.
The Sub/LFE channel (for DD / DTS material) can also be trimmed by up
to -10dB in 1dB steps useful for late night listening or other situations
where it might be desired to reduce the low frequency effect level
perhaps temporarily.
LFE Trim adjustments can also be made from the remote without the
OSD by pressing the LFE Trim button and using the Vol Up/Down
buttons.
Advanced bass management
The 340R also features an advanced bass management system which
when turned on allows the user to set different crossover frequencies for
different modes of operation, plus a special Bass Augment function.
To enable advanced bass management highlight the ‘Advanced Sub’
item in the Sub Setup menu and use the Left or Right arrows to turn it
on:
With advanced bass management now on, the ‘Sub Crossover’ item
disappears and a new item called ‘Advanced Menu’ appears. To make
changes to the advanced settings navigate to ‘Advanced Menu’ and
press Enter:
It is now possible to set three separate crossover points and Trim levels
(+/- 10dB) for each of the three main types of operation: DD/DTS
decoding, Pro Logic II decoding and Stereo + Sub operation.
Also possible is a Bass Augment function for DD/DTS or PLII operation.
In normal operation (Bass Augment Off) if the Front speakers are set to
‘Small’ (in the ‘Speaker Config’ menu) their bass is re-directed by high-
pass filtering the Fronts and sending that bass to the Sub channel (i.e.
bass is removed from the Fronts and sent to the Sub). If they are set to
‘Large’ no filtering takes place and no bass is sent from them to the Sub
channel.
However with the Bass Augment function On and the Front speakers set
to ‘Large’, bass from the Front Left and Right is now sent to the Sub
channel without any filtering of the Front Left and Right taking place (i.e.
these channels remain full range). In other words, the bass in the Sub
channel is augmented by extra bass from the Front Left and Right
channels. If the Front Left and Right are set ‘Small’, Bass Augment has
no effect and operation is the same as for Bass Augment Off.
Bass Augment can be On or Off separately for DD/DTS or PLII operation.
There is no Sub Augment function for Stereo + Sub mode because in
this mode if the Front speakers are set to ‘Large’ they will actually always
be unfiltered.
The 340R is able to allow the user to listen to one source whilst viewing
another. For instance this can be useful if it is desired to watch a sports
channel from say a set-top/satellite video source whilst getting audio
commentary from the Radio Tuner. Another example might be to listen
to a CD whilst watching a video channel, perhaps waiting for a TV
programme to start.
First select the Video channel you wish to watch in the normal way. Now
press and hold down the button for the channel you wish to listen to.
After 4 seconds approx ‘Audio Split’ will scroll across the display and you
will now be listening to the other source.
To cancel audio split mode simply select a new source and normal
operation will be resumed.
Bass/Treble configuration
Select the ‘Bass/Treble configuration’ menu:
The Bass response can be adjusted +/- 10dB @ 100Hz (shelving). The
Treble response can be adjusted +/-10dB @ 10kHz (shelving). The
‘Tone’ icon will light up on the display if these controls are adjusted away
from 0dB (flat).
Bass/Treble adjustments can also be made from the remote without
entering the OSD by pressing the Bass/Treble button and then using the
Vol Up/Down buttons.
Subwoofer setup
As covered in the ‘340R Setup’ section the 340R performs bass
management for any speaker that is set to ‘Small’ in the OSD. This
means that bass for speakers that are unable to reproduce it effectively
is instead routed to the subwoofer.
Select the ‘Sub Setup’ menu:
The crossover adjustment in the Sub Setup menu is used to determine
the point as which this transition is made. In other words it sets the
frequency below which bass is routed away from any ‘Small’ speakers
and into the Subwoofer channel. It should be understood that bass sent
to the subwoofer by bass management is different to bass encoded into
the surround-sound material as a dedicated Low Frequency Effects
channel. The crossover point can be adjusted from 40Hz to 150Hz in
10Hz steps.
If the source material contains a separate LFE channel (ie DD or DTS
material) this is always routed to the subwoofer (if it is On) and is not
affected by the crossover setting. Note: Pro Logic II does not actually
have a LFE channel.
