The Nº432/431 is capable of passing remarkable musical signals
regardless of signal and loudspeaker demands. On either an
instantaneous or continuous basis, these power amplifiers can
drive exceptional power levels into most all loudspeaker loads.
Depending on listening habits, loudspeaker demands, and the
number of power amplifiers present in the system – it is possible
for the electrical service to become the limiting performance factor.
In this case, consider installing a dedicated AC circuit for the home
entertainment system. Contact a licensed electrician for assistance.
If more than one AC circuit is providing power to the system,
contact a licensed electrician to ensure that all components are
operating with the same solid, low-impedance ground reference.
Important: Building regulations and electrical codes differ from location to
location, making it impossible to anticipate the requirements of
high-current AC circuits such as the Nº432/431 are capable of
using. Contact a local, licensed electrician for information.
Warm-up & Break-in Although the Nº432/431 delivers superior performance from the
Period first time it is powered on, this performance will continue to
improve as the power amplifier reaches its normal operating
temperature and various components “break in.” The greatest
performance improvements will occur within the first 25 to 50
hours of use. Sound quality will continue to improve for about
300 hours.
After this initial period, performance will remain consistent unless
power is disconnected from the ~ac mains connector. Power is
considered disconnected when the Nº432/431 is powered off with
the power button; the power cord is disconnected from the ~ac
mains connector or the electrical outlet; or an extended power
failure or power outage occurs. Power is not disconnected when
the Nº432/431 is in standby or sleep mode.
When power returns, the Nº432/431 will require a brief warm-up
and break-in period (not the full 300 hours). It is recommended to
allow the Nº432/431 and other audio components to stabilize for
about 2 minutes.
