The SPL-D2 is a sound-level display unit. This unit can be used as a stand-alone device, or it can be connected to the SPL5 limiter. The display is built-up with hi-efficiency bi-colour LEDs, so that it is clearly readable from a distance.


When connected to the SPL5 the display value is read from the SPL5 limiter. The bar can be used as a soundlevel indication bar, or as an attenuation bar.

When used as a stand-alone unit the measuring microphone must be connected. The display shows the actual measured value. When the value crosses the pre-defined level the display colour switches from green to red. This can be used as an indication for a live-band. When using a measuring microphone three measuring curves can be selected:

These settings can be changeg using the SPL-D2 configuration software.
