3 – Speaker delay settings

Note: Only enter these delay settings once you have speci ed what delay units (i.e.,

Time, Imperial or Metric) you will be using, or the information will be lost when

changing units. The measurement units can be speci ed on page 1 of this menu

(described on page 12).

The speaker distance control automatically sets

the appropriate time delays required for all the

speakers in your system. To set up the correct

speaker distance, you must measure from the

usual listening position to the front of each

individual speaker in the system. If the delay

units are set to Time, then enter the delay in

milliseconds for each channel.

The delay adjustment is not a substitute for proper speaker

placement, but helps to ensure accurate and correct signal

arrival times from all the channels to the primary listening

position.

No measurement can be entered for a speaker that is not

selected in the previous ‘Speaker Sizes’ menu.

4 – Level settings

It is very important to calibrate the speakers correctly to achieve an accurately-centred

sound stage. We recommend you use a sound pressure level meter (SPL meter) to

perform this part of the setup as it is dif cult to judge the levels accurately by ear alone.

Manual is best for setting up with an SPL meter as the test tone will not change to the

next speaker until instructed by you. Auto is best for setting up by ear as the test tone

changes automatically to each speaker after a two second burst of sound.

On  rst installation, watch the OSD display as you cycle through the available speakers

with the test tone. Check that the speaker in use corresponds to that indicated on the

OSD. If there is an error then check and correct the system cabling before proceeding

further.

To calibrate the speakers with an SPL meter, place the meter at ear level with the

microphone pointing towards the ceiling, when seated in the usual listening position. You will need to

set the meter to ‘C’‚ setting with a ‘slow’‚ response and to read 75dB SPL at the centre of the scale. This

volume is equivalent to normal conversation.

Each speaker can be  nely tuned by 0.5dB increments to ±10dB. The output from each speaker needs to

be adjusted to the 75dB SPL sound level. No adjustments can be made for a speaker that is not selected

in the previous ‘Speaker Sizes’ menu.

Note: If you do not have an SPL meter, simply set the front left speaker to 0dB on the menu and then

match all the other speakers to this level.
