WARNING: TO PREVENT FIRE OR SHOCK HAZARD, DO NOT EXPOSE THIS UNIT
TO RAIN OR MOISTURE.

The lightning flash with arrowhead, within an equilateral triangle, is intended to alert the
user of the presence of uninsulated “dangerous voltage” within the product’s enclosure
that may be sufficient magnitude to constitute a risk of electric shock to you.

The exclamation point within an equilateral triangle is intended to alert the user of the
presence of important operating and maintenance (servicing) instructions in the
literature accompanying the unit.

Observance of polarity is essential.  Double-check connections before turning
the amplifier on.  The amplifier can be damaged if polarities are incorrect.

Damage can occur to your speakers if the power rating* of each individual driver
is exceeded by the amplifier.  Ensure that all the drivers in your speaker system
are capable of handling not only the power being delivered by the amplifier, but
the energy that is likely to be generated during strong passages.

Turn amplifier ‘off’ when plugging in or unplugging input and speaker cables!!!

The ST1400 series 

II 

is equipped with raised feet so that continuous ventilation

can be maintained.  They help to maintain acoustic feedback into the amplifier at
a minimum.  They also provide a measure of protection against scratching any
surface the unit might be resting on.  

Do not stack anything on top of the amplifier (preamplifier, processor,
source...etc.).

Leave at least 2-3 inches clearance from the top of the amplifier to the next shelf,
component, etc., to ensure proper ventilation.

* If you are at all unsure of what the speaker ‘ratings’ are, contact your dealer.
