VIRTUAL SPEAKER CONTROLS
Press
MENU
and then a virtual speaker button
(
L, C, R, LS, OH, RS, LB, CB, RB, SW,
AUX, FEL, FER, REL, RER
)
to gain access to the menu for that virtual speaker.
Certain settings --
BASS
,
TREBLE
,
WINDOW
and
PROXIMITY
-- can be set for all speakers
simultaneously by pressing
MENU-
ALL
. Be careful, because this will overwrite many settings which
may have been set manually.
As an example, when
MENU
and then
L
are pressed, the screen says:
CH1(1) -> L vSPKR
>SHOW SPKR POSITIONS
L vSPKR SETUP1
L vSPKR SETUP2
The first line of this screen shows that channel 1 has been assigned to the left channel in the present
Realiser. The number in parentheses shows that in the Realiser used to capture the PRIR, at the time
of capture, left was assigned to channel 1. The number in parentheses is essentially irrelevant, because
the Realiser maps channels to speakers according to the labels, not the numbers. In other words, if the
measuring Realiser and the playback Realiser had different channel number assignments (but the same
set of speaker locations), the channels would map correctly in the playback Realiser because of the
labels. The numerical assignment of the measuring Realiser is displayed
only
because it may shed
some light on unusual measured layouts for which inadequate records may have been kept.
SHOW SPKR POSITIONS
displays a screen showing the azimuth and elevation of the virtual
speaker (
vSPKR
) in the preset in use, and the azimuth and elevation set for the present Realiser
(
SPKR
). The
SPKR
settings have no effect on the sound of the virtual speakers; the virtual speakers
will localise at the angles indicated by the
vSPKR
numbers. In other words, there is no need for the
SPKR
and
vSPKR
numbers to match. The
SPKR
and
vSPKR
numbers are displayed side by side as an
aid for those who may be experimenting with speaker positions in a given room and who may be
comparing present positions with those recently measured. The
SPKR
vs.
vSPKR
numbers will
quickly explain why the virtual speakers may not line up with the real speakers, if any, in the playback
room.
There are two submenus under the virtual speaker menus.
vSPKR SETUP1
-- brings up the following menu:
>FILTERS
MIX BLOCK
LFE GAIN:-- dB
LPF MIX:--
FILTERS
-- brings up a further submenu:
> BASS: OFF
TREBLE: OFF
ROLL OFF: 80Hz
HPF: NO
BASS
and
TREBLE
controls cover a range of
-12 dB
to
+12 dB
. If either is changed,
TON
appears at the bottom of the screen:
