Arcam DV29 manual Speaker set-up, Delay set-up

Speaker set-up

This menu screen allows you to specify the speaker configuration that is connected either to the analogue ouputs of your DVD player, or to your HDMI receiver when the HDMI link is carrying multi-channel uncompressed audio. (If you are using the coaxial or optical audio outputs, set all speakers to ‘Large’ or ‘Present’.) It is important that this configuration reflects accurately the actual situation, otherwise audio quality may be severely compromised.

The speakers are indicated as follows:

Front L/R	This is the setting for the ‘Front’ speakers (the speakers used for 2-
	channel stereo output).
Centre	This is the ‘Centre’ speaker setting.
Surround	This is the setting for the ‘Surround’ speakers (normally next-to or
L/R	behind the user).
Subwoofer	This is used to indicate whether a subwoofer is connected.

For each speaker, the player can be configured to send either audio with the full frequency range of the source material, or with a reduced frequency range. The reduced frequency range option is used normally when ‘satellite’ speakers are used for the surround channels; these cannot handle low frequency information. Full frequency speakers are commonly called ‘Large’ speakers, with reduced-range speakers given the name ‘Small’. Low frequency information is re- routed from ‘small’ speakers to ‘large’ speakers, or to the subwoofer (depending on the speaker configuration).

NOTES:

1.Any speaker that is not connected should be identified by selecting ‘Not Present’ for that speaker.

2.Although the DV29 is very flexible in the speaker configurations it can handle, some restrictions have been applied. For example, if no subwoofer is present, then it is not possible to configure the Front speakers to be ‘Small’ since there would be nowhere to redirect the low frequency information.

Stereo+Sub

This setting is relevant to 2-channel source material only (such as CDs). It controls whether the low frequency information is redirected to the subwoofer, or not. This item can be changed only if a subwoofer is specified as present in the system.

None	No redirection of low-frequency information occurs; all the audio is sent to the
	Front speakers.
Crossover	Low-frequency information is redirected to the subwoofer, with the remaining
	(higher-frequency) information sent to the Front speakers.
Duplicate	All the audio is sent to the Front speakers. In addition, the low-frequency
	information is duplicated to the subwoofer.

No sound from the centre/rear speakers? Ensure that the following are correct:

n A multi-channel source is being played;

n The ‘Audio’ item is set to ‘Bitstream/6 Ch.’;

n The connection between the DV29 and your audio device is made correctly – if using multi- channel analogue output, check that the cables have not been swapped.

Crossover Frequency

This setting defines the frequency at which bass redirection begins. Frequencies below this level are redirected from ‘small’ speakers to the Fronts or to the subwoofer; frequencies above this level are not redirected. The redirection frequency is the same for all the speakers in a system.

The optimum crossover frequency depends on the characteristics of your speaker set-up, and is best determined by experimentation. We suggest you start at 100Hz.

Delay set-up

The delay set-up menu page allows two different type of delay to be configured: those due to speaker positioning and those due to video post-processing.

Speaker positioning

The relative positioning of speakers within a room (particularly a large room) may mean that sound from some speakers arrives at the listener later than sound from others. By altering the delay settings for the different speakers, this difference in arrival time can be reduced or eliminated.

When setting the delay, it should be imagined that the listener is sitting in a circle of the speakers; the delay indicates the distance of the speaker from the listener.

Measurement Units

Your DV29 allows you to choose the measurement units that you feel most comfortable with: metres or feet.

Delays

Delays for the front, centre and surround speakers can be set using the associated sliders. A delay may be necessary for a speaker set if those speakers are further away from the listener than the others – specifying the different speaker distances will cause a slight delay to be added to the output of the closest speakers so that the sound from all the speakers will arrive at the listener at the same time.

Note that these delay sliders affect only the analogue and the HDMI outputs (although the HDMI output is affected only when carrying multi-channel uncompressed audio, not otherwise). The coaxial/optical digital audio outputs are never affected by changes here. If you are using these digital audio connections between the DV29 and your receiver, set all of the delays to zero.
