RFD-1 AC-3 RF Demodulator
The RFD-1 AC-3 RF Demodulator is used to convert the RF AC-3 signal coming out of an AC-
3 laser disc player to a digital data stream which the SSD-66 (5.1) can decode. The cable
which connects the AC-3 laser disc player's AC-3 output to the RFD-1's input and the RFD-1's
output to the SSD-66 (5.1)'s Digital Input is a standard 75Ω video/digital cable.
The RFD-1 has a DC Input Mute Switch on its back panel which can be set to either ON or
OFF. Normally, on laser disc players with an AC-3 output, DC voltage flows on the AC-3 RF
Input and thus the mute switch is left in the ON position. For older laser disc players which
have been modified to provide an AC-3 signal, the switch may need to be set to the OFF
position.
It is easy to determine the position this switch needs to be set to. With the laser disc player
connected to the RFD-1, begin playing a laser disc which is encoded with the Dolby AC-3
format. Making certain the RFD-1's Power Switch (front panel) is on (the Red power LED
indicator will be lit), check to see if the LOCK green LED indicator is lit (front panel). If the
LOCK indicator is off, switch the DC Input Mute Switch. The LOCK indicator should light up
green.
If the LOCK indicator is not on:
a. Make certain that the RFD-1 is on and that its Voltage Selector Switch is set to the
appropriate voltage.
b. Make certain that you are connected to the laser disc player's AC-3 output.
c. Make certain that you are connected to the RFD-1's AC-3 Input.
d. Check to see if the laser disc you are playing is AC-3 encoded.
e. Confirm that the 75Ω video cable is in tact.
f. If your laser disc has been modified for AC-3, you may need to consult with the provid-
ers of the modification.
