WARNINGS

The Full Power Balanced amplifier must be placed on a firm, level surface where it is not exposed to drip-

ping or splashing.

The ventilation grids on the top of the Full Power Balanced amplifier must be unobstructed at all times during

operation. Do not place flammable material on top of or beneath the component.

Before making connections to the Full Power Balanced amplifier, ensure that it is off and the preamplifier

is in mute or stand-by mode. Make sure all cable terminations are of the highest quality and free from

frayed ends, short circuits, or cold solder joints.

The differential circuitry employed with Full Power Balanced amplifiers requires special attention when connect-

ing speakers. Do not connect the negative speaker terminals together. Do not connect the negative speaker ter-

minals to ground or attempt to bridge the left and right speaker binding posts of Full Power Balanced stereo ampli-

fiers.

Do not connect a Full Power Balanced amplifier to a speaker selector device that employs a common

ground scheme, as it may short-circuit the amplifier output.
