Lexicon NT Series Amplifiers
Installation Selecting the appropriate installation location for your amplifier is perhaps the
single most important factor in ensuring a long trouble-free service life. Al-
though the amplifier is very conservatively designed, you must provide some
airflow around the unit. If you intend to stack multiple amplifiers in an enclosed
space, you should consider installing a fan or otherwise assuring adequate
airflow around the amps, as they rely on convection cooling.
As short runs of power and speaker cabling optimize efficient energy transfer,
try to locate the amplifier close to the speakers and power source.
All models in the NT Series share a rugged chassis design that can easily be rack
mounted with machine screws (#10 or M5). While the vast majority of weight
is in the front of each amplifier, support should be provided for the rear by a
shelf or bracket.
The amplifiers are designed to draw air in through the sides, cooling the heat
sinks, and ventilating out the top cover. To provide adequate ventilation when
racking multiple units, place a 1U spacer between amplifiers. We do not
recommend using a perforated panel.
An air inlet should be provided at the bottom of the rack, and a ventilator or
exhaust fan should be provided at the top.
