Continuous Operation

Note

Building regulations and electrical codes differ from location to location, making it impossible to anticipate the require- ments of high-current AC circuits such as the Nº33H. Contact a local, licensed electrician for information.

Although the Nº33H delivers superior performance from the first time it is powered on, this performance will continue to improve as various components “break in.” You should notice the greatest performance improvements within the first 25 to 50 hours of use. The amplifier should continue to improve in sound quality for approximately 300 hours.

After this initial period, performance will remain consistent unless power is disconnected, allowing the amplifier to cool down. (Power is considered disconnected when the Nº33H is powered off with the rear panel ~ac mains relay switch or the power cord is disconnected from the electrical outlet; or an extended power fail- ure or power outage occurs. Power is not disconnected when the Nº33H is in standby.) When power is returned, the Nº33H will require a brief warm-up period of about 2 minutes before the amplifier sound quality is at its best. (You will never have to repeat the full 300 hour break-in period.)

The Nº33H should be unplugged during lightning storms and extended periods of non-use. Otherwise, it is designed for continuous operation. For best performance, make sure the power cord is con- nected to an electrical outlet at all times. During normal opera- tion, do not use the rear panel ~ac mains relay switch to power off the Nº33H. Instead, use the standby button to place the Nº33H into standby, which allows the power amplifier to remain warmed-up to deliver optimal performance at all times.
