Note: These adjustments work in the digitally processed Stereo and

Surround modes but not in 6.1 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 holding down the Sub On/Off button and using the Vol Up/Down

buttons whilst it is kept down.

Advanced bass management

The 540R v3 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, PLII/Neo:6 decoding and Stereo + Sub operation.

Also possible is a Bass Augment function for DD/DTS or PLII/Neo:6

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/Neo:6

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 540R v3 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 ‘540R v3 Setup’ section the 540R v3 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. Some encoding types (Such as Dolby

PLII and Neo:6) do not actually have a LFE channel.
