Connections and warming up
There are several points that should be noted before using
your Delta 150.
In particular, it is advisable to switch off your system before
connecting it up to the Delta 150. This will avoid possible damage to
your loudspeakers. At the very least, ensure that the volume control on
your amplifier is turned down, or an unused input is selected.
Although the Delta 150 will receive broadcasts within
seconds of switching on, in common with other audiophile products its
internal circuits take some time to fully stabilise. We have found that the
very best sound quality may not be obtained until the unit has had some
time, maybe an hour or two, to warm up.
Note
When the Delta 150 is switched to standby mode, these
critical circuits remain energised. The optimum audio performance may
then be obtained as soon as the unit is switched on again.
