The Delta MONO utilizes premium quality binding posts that provide
an optimum torque feature which ensures the correct pressure or tightness
of the connection while preventing damage that can result from over-
tightening. Secure the speaker cables by tightening the binding posts until
you hear the clicks indicating you've reached the proper torque for the
connection.
5. Double-check all your connections.
We understand that this step sounds redundant, but it is worth the extra
minute or two it might take just to ensure that all connections are correct
and secure before plugging the power cables to the AC outlets.
6. Turn on all the other components in your system, and then
turn on your amplifier.
It is always good practice to turn any power amplifier on last, and to turn
it off first. Doing so prevents any turn-on/turn-off transients that might
originate in other components from damaging your loudspeakers.
Your amplifier will reach thermal equilibrium in 10-15 minutes. This
eliminates the need to keep the amplifier on for extended periods of time.
If you plan to not use it for a while, it is best to keep it in standby.
