Howdy

Can anyone provide the details for the audio output signals for PA1 devices?  We have been provided with PA1 devices and we're having some issues getting them to work with the existing VOX cards in the PA panel.  The behaviours between the 3.5mm line out and the speaker connection are different and we have been unable to find any detail about what the difference is between each audio signal.

Thanks

    Hi,

    The PA1 has one "MIC in" and one "LINE out" 3.5 mm connector for headset connection (SPK impedance = 150 Ohm, MIC power supply 3.3V, RL = 2 KOhm, S= -42 dB (+-2dB)). Microphone input must be differential and without grounding

    The "Speaker" output is driven by a 4 amp class D power amplifier, the output is 8 ohms

    Thank you
