warm-up/break-in period

operating voltage

Important!
Your new Classé preamp/processor delivers outstanding performance
immediately. However, you can expect to hear subtle improvements as it reaches
normal operating temperatures and breaks-in.
In our experience, you can expect the greatest changes within the first 72 hours.
After initial break-in, you'll enjoy consistent performance levels for years to
come.
The operating voltage of your Delta PRE is specified on the rear panel label that
also includes its serial number. .
Attempting to operate your Delta PRE from an incorrect AC
voltage source may cause irreparable damage which may not
be covered by your warranty.
If you are not planning to use the preamp/processor for an extended period of
time, for example due to vacation or other travel, we suggest that you disconnect
it from AC power.
Make certain that the Delta PRE is in Standby prior to disconnecting it.
Physically disconnect any and all valuable electronics from AC power during
electrical storms. A lightning strike anywhere near your home can generate a
tremendous surge on the AC mains that can jump across a simple power switch.
A surge from a lightning strike, which may be many thousands of volts, can
cause serious damage to any piece of electronics, no matter how well designed
and protected.
