SAFETY PRECAUTIONS
PLEASE READ BEFORE INSTALLING
•
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!!!
•
When plugging in or unplugging interconnect cables running from
source to preamplifier, always mute the preamplifier and rotate the
preamplifiers volume control to minimum first. It is recommended that
you turn the amplifier 'off as well for this operation.
•
The EX4420 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
after or remove them.
•
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
neDdshelf, component, etc., to ensure proper ventilation.
• If you are at all unsure of what the speaker 'ratings' are. contact your dealer.
