ADA RFD-1 AC-3 RF Demodulator
Laserdisc Player with only an AC-3 RF Output
The Cinema Rhapsody Mach II features an input label for connection to an AC-3 RF demodulator,
needed for laserdisc players that have a Dolby Digital AC-3 RF output. Some players manufactured
after 1994 feature this output while others may have been modified with an additional AC-3 RF Output
(MSB Technologies provided this modification). These players require an external AC-3 RF demodu-
lator (ADA’s RFD-1) for playback of Dolby Digital (a.k.a. AC-3) laserdiscs using Dolby Digital decod-
ing. Here, the laserdisc’s AC-3 RF output is passed into the RFD-1 and then to an open digital coaxial
input on the Cinema Rhapsody Mach II. You need to use one of the four digital coax inputs for
connection to the RFD-1.
The Out of the Box configura-
tion for the LASER AC3 input
label is the Digital 2 coaxial
jack. Please note, you will also
need to make the secondary
optical TOS-Link digital audio
connection (for non-AC3
laserdiscs) and video connec-
tions to the Cinema Rhapsody
Mach II. As such, when play-
ing regular stereo or DTS
laserdiscs, you will need to
select the LASERDISC input
label. When playing Dolby
Digital (AC-3) laserdiscs, you
will need to select the LASER
AC3 input label.
Laserdisc History
As a point of information, the
laserdisc, introduced in the
late 1970’s, today contains
four audio channels. Two
channels contain PCM digital
audio for playback of standard
laserdiscs (CDs also contain
two channels of PCM digital
audio). The other two chan-
nels on a laserdisc date back to the late 1970’s, prior to the implementation of PCM digital audio
(1983). Here, an audio signal is modulated onto a mono FM radio frequency. There is a mono FM
channel for left and another for right. Those who viewed laser discs prior to the mid-1980’s, listened to
the analog channels as the digital channels did not yet exist.
In 1994, when Dolby Laboratories introduced AC-3 (now called Dolby Digital) for the home theater
market, they decided that it would be best to include the AC-3 multi-channel digital bit stream on every
laserdisc pressed (rather than release a special-order laserdisc). Because all players since the mid-
80’s read the digital PCM channels (rendering the mono-FM channels obsolete), Dolby decided to use
one of these two antiquated mono-FM channels to embed (or modulate) the AC-3 bit stream. Thus, in
order to decode the AC-3 bit stream from a laserdisc, one must first demodulate the mono-FM channel
to extract the bit stream. In essence, the RFD-1 is a radio-frequency tuner (demodulator), hence the
terminology-RFD. As the mono-FM signal passes through the RFD-1, the AC-3 bit stream is demodu-
lated, emerging from the RFD-1 as a Dolby Digital signal, the exact same output as that of a DVD
player.
