For adjusting the back-surround channels, you will need a RCA “Y” splitter.
Unplug the right and left surround inputs to the ADA 6.1 and plug the “Y” connector into both left
and right surround inputs on the ADA 6.1. Take the right surround channel and plug it into
the open end of the “Y” connector.
Engage the pink noise generator for the right surround channel. Make certain that the ADA 6.1 is
on.
At this time, you should hear pink noise coming from the back surround speakers. Use the back
surround level adjustments on the ADA 6.1 to raise and lower the level until the SPL meter
reads -72 dB. If you are using two back-surround speakers and they are equal distance to
the primary listening position, the two knobs on the ADA 6.1 for back-surround should be
set so that they are both about the same. If one speaker is further away than the other, you
will want to adjust these knobs so that you hear both speakers relatively evenly from the
primary seating position.
At this time, you have adjusted the back surround speakers on the ADA 6.1.
To reconnect the system, unplug the “Y” connector from the ADA 6.1 and reconnect the right and
left surround inputs to the ADA 6.1.

Note: If you are using a Cinema Reference, you
do not need to use the “Y” splitter because the
Cinema Reference has a pink noise mode for
both right and left surrounds active together
that has the same effect as using a “Y” splitter.
Therefore, do not disconnect the ADA 6.1
inputs. Simply select the NOISE L/R SR setting
in the Cinema Reference’s noise mode.
