hd receivers r23-700

[zmac]

installed 4 receivers, added 4 more later(2 weeks)

when tuned to the same channel there is a time delay between
the 2 sets of 4, simular to the difference between hd and sd

any suggestions

How long is the delay?

 

[zmac]

hd r23-700

the delay time is about 1second

 

[raoul5788]

the delay time is about 1second

I am confused. Do they all have the same audio connections? Do you have them all on at the same time?
