Operation
                             DATEQ SPL-D2 Manual
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 functions as a VU-meter, the display gives the actual SPL.  
As soon as the sound-level exceeds the pre-set threshold the LED's will light up red. 
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 audiolevel 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 diskjockey. 
The display units hold three correction-curves: 
• ANSI-A 
• ANSI-B 
• ANSI-C 
The measured values can be adjusted to match 
a calibrated meter. By moving the slider to the 
right the microphone becomes more sensitive. 
Moving the slider 
to the left gives a higher level. 
Common settings 
The display can be dimmed automatically in a dark environment. This function can be enabled by 
selecting 'Auto ambient light correction’ 
The intensity of the ‘numbers and the Vu meter can be adjusted with the sliders as can be the 
response time of the Vu meter.
