XTP CrossPoint Series • Operation
55
For each display scheme, the input buttons blink or light sequentially to indicate the approximate
volume of the selected output. Volume is defined as a percentage of the input audio signal
that is applied to the output. From 0% of volume, the first
Esc
(
>
) button push applies 5.5%
of the input audio signal. From 5.5% on, each
Esc
(
>
) push applies 1.5% more of the input
audio signal to the output:
•
Push Esc (
>
) button again
— 5.5% + 1.5% = 7% volume
•
XTP CrossPoint 1600
—
Input 1
blinks slowly
•
XTP CrossPoint 3200
—
Input 1
lights steadily
•
Push Esc (
>
) button twice more
— 7% + 1.5% + 1.5% = 10% volume
•
XTP CrossPoint 1600
—
Input 1
lights steadily
•
XTP CrossPoint 3200
—
Input 1
and
Input 2
light steadily
•
Push Esc (
>
) button 19 times more
— 10% + (19 times 1.5%) = 38.5% volume
•
XTP CrossPoint 1600
— Input 1 through
Input 5
light steadily and Input 6 blinks
•
XTP CrossPoint 3200
—
Input 1
through
Input 11
light steadily and Input 12
blinks
When all input buttons are lit, the audio output is 100% of the audio input level.
Another way to view the volume level is to think in terms of the attenuation that is applied to
the output. Attenuation reduction is indicated by the lit or blinking input buttons: when fewer
input buttons are lit, attenuation is greater (and the volume is quieter).
•
At minimum volume, all input buttons are unlit or background illuminated and 76 dB of
attenuation is applied to the output. The audio output is effectively muted.
•
The first step of volume increase causes
Input 1
to blink. Attenuation is reduced by
13 dB (63 dB of attenuation is applied to the output).
•
The second step of volume increase reduces the attenuation by an additional 1 dB
(62 dB of attenuation is applied to the output). (On the XTP CrossPoint 3200,
Input 1
lights steadily.)
•
Successive steps of volume increase cause consecutive input buttons to first blink and
then light steadily. (On the XTP CrossPoint 3200, each consecutive button indicates a
1 dB
attenuation reduction when blinking and a
2 dB
attenuation reduction when lit.)
For example
: When lit steadily,
Input 3
indicates the following, depending on the
matrix switcher model:
•
XTP CrossPoint 1600
— 52 dB of attenuation when compared to
Input 3
blinking (53 dB to 55 dB of attenuation).
Input 4
blinking (49 dB to 51 dB of
attenuation) is at least 2 dB less than
Input 3
blinking (53 dB minus 51 dB) and at
most 6 dB less (55 dB
minus
49 dB).
•
XTP CrossPoint 3200
— 58 dB of attenuation when compared to
Input 3
blinking (59 dB of attenuation).
Input 4
blinking (57 dB of attenuation) is 6 dB less
than
Input 2
steadily-lit (60 dB
minus
57 dB).
•
On the XTP CrossPoint 3200
, the volume indications of the buttons are additive.
For example
:
Input 1
lit (
23 dB
[22 dB + 1 dB] of
attenuation reduction
),
Input 2
lit (
2 dB
[1 dB + 1 dB] of
attenuation reduction
), and
Input 3
blinking (
1 dB
of
attenuation reduction
) indicate that the output
attenuation has been reduced
by a
total of
25 dB
(
22 dB
+
2 dB
+
1 dB
=
25 dB
).
•
At full volume, no attenuation is applied to the output and all input buttons are lit
steadily.
