Sub Out
This a symmetrical and buffered output representing the input signal.
This enables you to chain as many Sub12 in a row as you like. The
Sub Level effects the output, so that all possible chainmembers can
be levelled at a time. Instead of one very big subwoofer it often is better to have
2 smaller ones to avoid some of the standing waves at very low frequencies. This
always means a little bit of testing, as it is not possible to predict the behaviour of
a subwoofer in unknown acoustical circumstances.
Input - Balanced and Unbalanced
Satellite out - Balanced and Unbalanced
Final recommendation:
After using the set up a few times we recommend to test the position of the controls
again. In most cases, when the excitement about the new bottom has become
less, you prefer a solution with less bass level, and from our experience this will
be the more correct one.
These stereo jacks - XLR in the balanced (also named:
symmetrical), Cinch or RCA in the unbalanced (also
named: asymmetrical) case, should be connected to
the output of your mixing console or stereo/surround
sound system.
These jacks should be connected to the inputs of your
active studio monitors or the inputs of a power amp that
drives passive monitors. The signal is simultaneously
available from all connectors.
