The menu will then drop down to the first channel (Front Left) and the
test tone will be heard to come from this channel only. You can now
move up and down the channels using
Volume up/down
on the remote.
Each time a new channel is selected the test tone will be heard to move
to that channel. Compare the loudness of all channels as heard at the
listening position.
The idea is now to adjust the channels so they all the same (in terms of
loudness only, channels of different frequency responses can sound
different in terms of the 'tone' of the sound i.e. more or less hissy).
Pick the channel that sounds most different and select it to listen to the
test tone. Now adjust the relative level in dB (using
Arrow left/right
on
the remote) and continue comparing it to other channels until it is of
equal loudness. The level can be adjusted up to + or - 10dB in 1dB
steps. Repeat the process with the next loudest channel etc. Once all
channels sound the same in terms of loudness, press the
OSD
button
again to save the settings and exit the menu.

Set the distances in the OSD Speaker Delay menu to the nearest value
in metres (delays of 0-60mS are possible). The 540R V2.0 OSD shows
both the equivalent distances and delay times for reference.
The delay settings can also be set from the front panel by pressing the
Delay
button on the remote. The display will show “L-R” and a distance
in meters for front Left (and Right). Pressing the
Delay
button again will
show “C” and again a distance etc. Use
Volume up/down
to adjust the
distance to that actually measured. When finished make no adjustment
for a few seconds and the 540R V2.0 will save the settings and exit the
menu.
Step 3 - Level Calibration
The 540R V2.0 allows Level Calibration to match the acoustic level
between different types/sizes or even manufacturers of speaker that
may be being used for each channel. This is achieved by adjusting the
relative level of each speaker through either the Level Calibration menu
in the OSD (recommended) or via the front panel display.
The basic process is to listen to or measure with an SPL meter (more
accurate and recommended but not essential) the level of sound
produced by each speaker and set relative levels for each speaker so
that they all sound the same loudness at the normal listening position.
The 540R V2.0 incorporates a Test Tone generator (actually broad-band
White Noise) to facilitate this.
For setup via OSD:
Set the unit to a normal listening level or half maximum volume
approximately. Press the
OSD
button on the remote control then select
the Level Calibration menu. Now turn on the test tone by selecting item
‘A’ and using the
Arrow left/right
controls on the remote.
