3 & 4 can be assigned to any of
4 groups. However, ( 1 & 2 ) and ( 3 & 4 ) cannot share same Group .

Phase Meter : 90 deg (default); When monitoring a stereo signal,
the coherence between the 2 channels (i.e., how similar they are)
greatly affects its mono compatibility. The phase meter indicate the
relative phase of the 2 channels and thereby provide some
measure of mono compatibility. Phase meter reading in the upper
half of the scale indicate acceptable mono compatibility, whereas
lower half readings warn of a potential compatibility problem.

Alignment :
–20 dBFS in SMPTE digital unit or 4 dBu in VU unit (default);
user adjustable; also known as the safe range.

Alarm : 0 to
–9.9 dBFS (default);
0 to
–20 dBFS depending on “alignment” setting;
the
“alarm” range is equivalent to the upper half of 0 dBFS minus
previous item
“alignment” setting.

Headroom :
–10 to –19.9 dBFS (default);
–20.7 to –41.58 dBFS depending on “alignment” setting the
“headroom” range is equivalent to the lower half of 0 dBFS minus
“alignment” setting; also known as the headroom before alarm
range is reached.
dBFS (decibels relative to full scale)
VU (volume unit)
The Rainier 3G Plus is capable of displaying embedded audio as VU
meters inside the video window. Embedded audio is divided into four
groups (
CH1 to CH4 ), with a master ( Meter 1/2 ) and secondary channel
( Meter 3/4 ) for each group. This allows the display of the left and right VU
meter of either the master or secondary channel on the left and right side
of the window just as the menu depicts. Adjust the
Phase ( Out of phase
slider), VU (one slider), Sound ( H igh/ L ow sliders). If there is no audio
detected, NO VU meters will be shown.
Audio Meters & Groups:
Along with the video signal(s), each input signal may contain up to sixteen
channels (8 pairs) of embedded audio.
Typically, 48kHz, 20-bit audio; (extendable to 48kHz, 24-bit audio).
Use the
Group setting to select which group of embedded audio to
monitor. In accordance with SMPTE standards incoming audio may be
embedded in up to 4 groups with each group containing 4 channels. For
example; a simple stereo signal would typically use:
Ch annels 1 & 2 which
can also be thought of as Meter 1 - L eft and Meter 1 - R ight. The Rainier 3G
Plus is capable of displaying 8 Channels (2 Groups) at a time. Meter s 1 / 2
are always displayed on the left side of the screen and Meter s 3 / 4 are
always displayed on the right side of the screen. However, associate any
Group to any
set of meters which, for instance; would allow Group 2 to be
displayed on the left side of the screen.
Recap:
Any of the 4
Group s can be assigned to Meter s 1 & 2 and any of the 4
Group s can be assigned to Meter s 3 & 4 .
Note: Upon changing audio source entering VIDEO IN port; make sure to
refresh audio meters by either re-
selecting “
On
” option in “
Meter Enable
”
menu. Or, by physically disconnecting and then reconnecting signal cable
entering
VIDEO IN port. Refreshing audio meters is necessary for Meter s
3 & 4 to display correct dynamic meter bars.
Outside
(On / Off)
Allow the location of the audio meter to be outside the video area.
