the Control A bus. The SIRCS signal is product specific so only the
device the command is designated for will respond, even though all
devices receive the command.

No Delay of Playback between CD Changers – The next disc in the
programmed (or shuffle) play order will load and pause 30 seconds
prior to the current track ends so there is no delay in playback.
Generations of Control A
There are three Control A software formats. The formats are backwards
compatible.
Control A – Used on early 50 and 100 disc CD Changers enabling the
auto function selection and Syncro Recording features. The first genera-
tion used a 3.5mm stereo miniplug instead of the current mono plug used
in future generations. Connecting old and new units using a stereo to
mono cable can make them hardware compatible.
Control A1 – Used on 200 disc CD Changers, permitting more system
features as listed, enabling automatic operations associated with inte-
grated systems. This second generation format began the use of a 3.5mm
mono miniplug for bi-directional communications.
Control A1 II – Began on the 300-400 disc CD Changers in the year 2000.
The version II software additions to the changer's microprocessor permits
audio – video system functions that are not at full potential as of this
writing.
Control A Hardware Connections
Connecting the audio devices for communications requires a coax cable
(2 meters max length) with a 3.5mm mono miniplug at each end. Each
audio device is linked to another using these cables forming a series. The
cable plugs into either one of the two Control A jacks at the rear of the
audio device (the receiver only has 1 jack so it must be at the end of the
path).

Changer 1
There is a three-position command mode slide switch next to the Control
A jacks of the newer CD Changers. The older changers are considered in
position one (1). The command switch selects the CD player number.
This is useful if you want to control the CD Changers independently or as
a group.
If you want to control the changers independently you would assign each
changer a different position number. Then if you wanted to select a disc
from the second changer by remote, side the remote's CD switch to #3 to
access changer #3.
If you want to group two changers for combined features so they operate
together, place two of the changers into position #2. Then you can use
some of the features that share changer operation like Displaying Cus-
tom Files on the TV screen, Program Play, or Cross (X) Fade Playback.
