The Realiser can accommodate two head-top modules with a single set-top. The screen above reports
the status of both head-tops. In this example, there is only one head-top in use, Tracker 0, so the
Realiser reports errors for nonexistent Tracker 1. (See below for tracker designations.)
The screen displays, in real time, the angle of the head tracker position, the signal strength, and the
battery charge status. To exit the tracker status screen, press
CANCEL
.
Tracker adjustments
Pressing
MENU-TE
gives access to head tracker menu. The screen will say:
MODE:Ir1 RANGE:L
0°
>TKR NO:0
FILTER:360°/s
The head tracking system has two modes. The modes are set using a small switch on the side of the
set-top and a small switch on the head-top. On both modules, the switch is on the right side if you are
looking at the
SMYTH SVS
legend.
For s
ingle-user mode
, both switches should be up. This is the default and recommended mode for
single users. In this mode, the single head tracker (headband unit) is designated #0, the default setting,
and the Realiser is set to respond to #0 (default).
Dual-user mode
supports two listeners with independent PRIR, HPEQ and head tracking. For dual-
user mode, both switches should be down. See Dual-User Mode for specific instructions on setup.
The menu line items are as follows.
MODE
-- The designation reported will be
IR1
when the switches are up for single-user mode, and
IR2
when the switches are down for dual-user mode.
RANGE
-- The set-top has two levels of infrared brightness corresponding to long-range and short-
range operation. In single-user mode, the range changes automatically with the distance between the
set-top and headband tracking units, and the
TE
screen indicates the range by displaying
L
for long and
S
for short. In multi-user mode, the range is always set to long. The set-top produces strong enough
IR to allow up to about ten metres or about thirty feet separation between itself and the head-top. The
actual usable maximum distance will vary according to ambient light conditions.
OFFSET
--
An offset adjustment is provided to shift the virtual speakers slightly to the left or right.
This would need adjustment if the set-top position were off centre (different position in the
measurement setup versus the listening setup), or if the head-top were off centre during the
HT
method
of logging look angles. (See
MENU-SPK
.)
Position the cursor at
OFFSET
and use the
<
and
>
keys to shift the image left (negative numbers) or
right (positive numbers).
TKR NO
-- For dual users, the two head-tops must be configured to be #0 and #1, respectively. To
change the configuration, plug the head-top into the
HT-CHARGE
socket on the Realiser front panel.
Also, the set-top must be plugged into the Realiser rear panel. Press
MENU
, then
TE
. The screen says:
