STEREO
It is possible to duplicate the above solution to give a 2
channel stereo solution. However if the oscillator
frequencies are not locked together, a beat can occur
which is acoustically audible. This is undesirable. A
stereo solution which avoids this problem can be
achieved by synchronising the operating frequencies
of both ZXCD1000

Great care must be taken when linking the triangle
from the master to the slave. Any pickup can cause
slicing errors and result in increased distortion. The
best connection method is to run two tracks, side by
side, from the master to the slave. One of these tracks
would be the triangle itself, and the other would be the
direct local ground linking the master pin9 ground to
the slave pin 9 ground.
A demonstration board, ZXCD1000EVSOL, is available
for a stereo 25W solution.
