Prerequisites
•
Ensure that the music source follows these guidelines:
— Nominal input impedance is 3.3 kilohms.
— Nominal sensitivity of this interface returned to digital encoded PCM is
–22 dBm0 for a 0.25 V rms input signal.
— The input is limited so that the encoded analog content at the digital
interface to the network does not exceed –12 dBm when averaged
over a three-second interval.
— The maximum nonclipped input level is 1 V rms.
— The interface is protected against ringing cross.
