Operating Voltage

The Nº32 Reference Preamplifier is set at the factory (internally) for 100V, 120V, 230V, 220V, or 240V AC mains operation @ 50 or 60Hz. (230V/50Hz only in European Union countries, in compliance with CE regulations.) This voltage setting cannot be changed by the user.

Make sure that the label near the AC receptacle of the Nº32 Controller indicates the correct AC operating voltage for your location.

If the voltage indicated on your Nº32 Controller is incorrect, or if you wish to change the AC operating voltage of your Nº32 as the result of moving to a different country than the one in which you purchased your preamplifier, see your Mark Levinson dealer.

The Nº32 is easily powered by a normal 15-ampere AC mains line. If other devices are also powered from the same AC line, their additional power consumption should be taken into account.

It is extremely important that all components in your

system be properly grounded. Do not defeat a three- 11 prong AC cords with “ground-lifter” or “cheater”

adaptors, as doing so may allow dangerous voltages to build up between components. The presence of these voltages would pose a threat to both your person and your equipment.

Although your Mark Levinson Nº32 Reference Preamplifier delivers outstanding performance straight out of the box, you should expect to hear it continue to improve as it reaches its normal operating tempera- tures and its various components “break-in.” It has been our experience that the greatest changes occur within the first 25-50 hours, but that the preamplifier will continue to improve in sound quality for about 300 hours, after which time it remains quite constant.

The only exception to this rule is if power is removed from the unit, al- lowing it to cool down. In this case you should expect a brief warm-up period before the preamplifier’s sound quality is at its best. (Fortu- nately, you do not have to repeat the full 300-hour break-in period.)
