Performance tips

Protection circuitry

After making your loudspeaker connections, apply power to your preamplifier and allow it to stabilize. (Mark Levinson preamplifiers, for example, require about one minute to stabilize.)

Connect the AC power cord (included in the accessory pack) to the AC connector on the rear panel of the Nº29, then to the AC mains outlet.

Turn on the Nº29 by setting the power switch on the front panel to the "" (on) position.

Note: You may hear a transient "click" or "pop" through your speakers a few seconds after you operate the Nº29's power switch. This noise is normal and won't damage your speakers.

The Nº29 won't achieve its sonic potential right away — its sonic performance is close to the optimum after about 100 hours of use. For the best performance, you may leave your Nº29 powered at all times, except when you won't be using it for a long period (see "Important Safety Instructions").

The Nº29 is designed to be "power-cycled" (that is, turned on and off) without affecting its longevity. After the amplifier is turned on after being left unpowered, allow for about one hour of warmup before expecting optimal sonic performance.

Under certain conditions (an electrical malfunction or inadequate ventilation), the Nº29's protection circuitry may activate, turning off the amplifier before damage results. When this happens, the power switch on the front panel will be set automatically to the "O" (off) position. After a brief cooling period, you can reactivate the amplifier by setting the power switch to the "" (on) position.

If this occurs regularly during normal use, see your Mark Levinson dealer immediately.

Note: While the protection circuitry is active, the power switch won't stay in the "" (on) position. If, after the amplifier has cooled, the power switch still won't engage, the protection circuitry still detects a malfunction; see your Mark Levinson dealer immediately.
