PRECAUTION

Unpack your Nº29 amplifier and keep all packing materials for future transport.

To avoid damaging the connectors on input cables attached to the rear panel, NEVER rest the Nº29 on the rear panel, and NEVER tip it back in a way that would put stress on these connectors.

Carefully inspect your Nº29 for damage and flaws. If you find any, see your Mark Levinson dealer immediately.

To keep speaker cables as short as possible, place the Nº29 as close to the loudspeakers as practical.

Place the Nº29 at least three feet from the turntable and preamplifier. Otherwise, the Nº29 may induce hum into these sensitive components.

The Nº29 may be placed in a cabinet or on a shelf, but adequate ventilation must be provided to prevent overheating. The clearance provided by the unit's feet must be maintained to ensure unrestricted air flow across the bottom of the chassis. (Placing the Nº29 on carpeting, for example, may prevent adequate air circulation.) Clearance above the unit must also be maintained to allow air circulation and to prevent heat buildup.

The Nº29 incorporates thermal sensors located near each group of output devices. If the internal heatsink temperature becomes excessive, these sensors will shut off the amplifier before damage results. After a brief cooling period, the amplifier can be reactivated via the front-panel switch. If this occurs regularly during normal use, it's an indication that the ventilation provided for the amplifier is inadequate. If there's adequate ventilation and the problem continues, see your Mark Levinson dealer immediately.

For those involved in custom installations and cabinetry, this information may be useful:

■All temperature measurements are made at the bottom of the internal heatsink, 2 inches above the chassis floor.

■Normal heatsink temperature at idle after warmup with unrestricted airflow at 22° C (72° F) ambient temperature: 35° C (95° F).

■Maximum permissible heatsink temperature before thermal protection is activated: 80° C (176° F).

Drawings are included in this manual to facilitate special installations and custom cabinetry (see "Dimensions").

For your protection, review "Important safety instructions" before you install your Nº29.
