Installation Considerations

The Nº33H requires special care during installation to ensure optimal performance. Pay particular attention to the information included in this section.

Your Mark Levinson Nº33H Monaural Power Amplifiers are specifi- cally designed to stand on the floor, and must be used as free- standing units. In most installations, locating them near the loud- speakers is best. Obviously, this approach minimizes the length of the speaker wires and necessitates longer interconnecting cables from the preamplifier to the power amplifiers. The advantage to this strategy is that that the interconnecting cables carry low-cur- rent signals which are more readily transmitted over distances with great accuracy than are the necessarily high current signals required by loudspeakers.

You should leave at least six inches (15 cm) of free space behind each Nº33H so that the AC cord and connecting signal cables have sufficient room to bend without crimping or undue strain.

You should also position each amplifier for easy access to the rear panel power switch. This switch effectively disconnects the ampli- fier from the AC mains.

Before moving the Nº33H, make sure it is powered off with the rear panel power switch. Then, make sure the power cord is disconnected from the electrical outlet.

Your Mark Levinson Nº33H power amplifier is designed to com- plement your listening room visually, with a tall and narrow frontal area that reduces the effective “footprint” and makes it far more presentable than would be the case with a more traditional- ly proportioned design. As a result, it can be more easily placed beside your loudspeakers. As freestanding units, the Nº33H ampli- fiers normally will have no problem with ventilation. Please fol- low the precautions below.

•DO select a dry, well-ventilated location out of direct sunlight.

•DO ensure free air flow around the Nº33H to allow for adequate heat dissipation through air circulation.

•DO keep the top plate and heat sinks free from obstructions that could reduce air circulation.

•DO use fans to increase air circulation if the Nº33H is installed in an enclosed space.
