Maximum Power(Siren + Message):
1000W
Maximum Power @ 1kHz: 1.6W
Bandwidth @ -3dB = 100Hz ~ 12kHz
Configurable Audio Input
Sensitivity
For each channel of a configurable audio input card, there are five levels to gain the audio signal.
They are sensitivity values of 0dBu, -12dbBu, -24dBu, -40dBu and -54dBu respectively. The
meaning of sensitivity value is how large the gain is for an audio source, and to amplify the
giving minus input source to 0dBu. The figure below is an example of when the sensitivity value
is set to -54dBu, and input source is -54dBu, after the gaining circuit of the audio card you'll get
the 0dBu of output.
Output Impedance =10k Ohm
Bandwidth =±1dB@ 20Hz ~ 20kHz
THD+N (Total Harmonic Distortion plus Noise)
PDC
@ -3dB at output = 20Hz ~ 20kHz
@ -3dB at input < 20Hz ~ 22kHz
Distance up to 1000 meters for using external power supply.
Note: The distance using internal power supply is differ from each product.
