SAFETY PRECAUTIONS

 

PLEASE READ BEFORE INSTALLING

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.

Ÿ

Observance of polarity is essential.  Double-check connections before turning the 

  

amplifier on.  The amplifier can be damaged if polarities are incorrect.

Ÿ

Damage can occur to your speakers if the power rating* of each individual driver is

 

exceeded by the amplifier.  Make sure 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.

Ÿ

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

Ÿ

The Reference 7250/7260 series II is equipped with raised feet so that continuous
ventilation can be maintained. They help to keep 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 alter or remove them

.

Ÿ

Do not stack anything on top of the amplifier (preamplifier, processor,                      

 

source...etc.).

Ÿ

Leave at least 2-3 inches clearance from the top of the amplifier to the next shelf,   

 

component, etc., to insure proper ventilation.

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