AUDIO INPUT/ OUTPUT LEVELS
The ideal audio input level is 0dBm
600
. (This is 1mW across the 600 Ohm input impedance.) On a
voltage basis, this is equal to 0dBV or 2.19 Vp-p. Higher input levels will cause increased distortion. Up
to +3dBm, the distortion will increase a small amount. Above this level the distortion will increase
rapidly. Lower input signal levels will reduce the signal to noise ratio. In either balanced or unbalanced
configuration, the input impedance is 600 Ohms.
The audio output signal appears on both the plus and minus terminals of this unit. Half of the signal
appears on each output terminal. The two outputs are 180° out of phase. The balanced output
impedance is 600 Ohms while the unbalanced output impedance is 300 Ohms. The output signal level
will be half of the input level (-6dB) in an unbalanced configuration.
RR-0800 STATUS INDICATOR
The RR-0800 provides the following LED status indicator to aid in installation and troubleshooting:
OLI
A bi-color LED indicator monitors the optical input power of the audio signal that is being received at
the RR-0800 from the MT-0800 or the RT-0800. Internal DC power and optical input status associated
with this LED are summarized below.
