Display connected to the SPL5
When the display is linked to the SPL5 the microphone values will be downloaded from the SPL5
automatically. Those values will be showed in the large display.
The LED-bar can become a VU-meter, or a reduction meter. When using the bar as a reduction
meter the small digits underneath it indicate the amount of attenuation.
As soon as the sound-level exceeds the threshold the LED's will light up red for some time. When
a small audio peak exceeds the threshold the tekst 'dBA' will start blinking.
Connecting to the SPL5
The display unit is connected to the SPL with the jack connector. A standard microphone cable
can be used. Connect the shield to the jacks' ground pin and the signal wires to the tip. At the
SPL5 the shielding can be connected to pin 14, and the signal wire to pin 8 of the DB-25
connector.
Using the display stand-alone
To use the display as a stand-alone device the microphone has to be connected. The audio-level
will be showed in the large LED display.
By means of the PC-software the threshold can be
adjusted. When the audio-level exceeds this level the
LED's will become red. This can be used as a warning
for the live-band, or the disk-jockey.
The display units hold three correction-curves:
C
ANSI-A
C
ANSI-B
C
ANSI-C
The measured values can be adjusted to match a
verified meter. By moving the slider to the right the
microphone becomes less sensitive. Moving the slider
to the right gives a higher level.
Common settings
The display can be dimmed automatically in a dark environment. This function can be enabled by
selecting 'display dimming'.
The intensity of the various elements can be adjusted with the boxes at the bottom of the window.
