Caution

Turn off the 

kW

amplifier at least five minutes before you

connect, disconnect or make any changes.

To explain further:

The RMS power capacity of the 

kW

is far higher than the theoretical short-term peak current

of an ordinary amplifier.  Used wrongly, this power can vaporise your speakers.

If you make an error when changing the interconnects, an 

ordinary

power amplifier will try to

deliver its peak power and current into the loudspeaker.  This might only last for a few micro-
seconds, not long enough to damage a properly designed loudspeaker.

The 

kW

, however, behaves differently when an error is made.  As its RMS power is much

higher than almost any other amplifier’s peak rating, the 

kW

will deliver its peak power for as

long as the problem exists.  If you react quickly, you may pull out the offending cable in half a
second.  A small error, but more than enough to vaporise you loudspeakers, because the 

kW

will release between 1000 and 5000 watts peak into them.  One mistake, and it’s bye-bye
speakers, so . . .

To protect your loudspeakers, ALWAYS turn the 

kW

OFF before changing any interconnect,

or doing anything which might cause the amplifier to deliver its full peak power and current
into your loudspeakers.  At Musical Fidelity, we treat the 

kW

with extreme respect.  

When we

change interconnects, or do any form of maintenance, we ALWAYS TURN IT OFF at
least five minutes before touching anything.

The 

kW

will deliver truly astonishing dynamics and control into any loudspeakers, but because

of its stupendous power, voltage and current ratings, you must think before acting.

When working with the 

kW

, we always “think fast, act slow”, and so far, we haven’t blown

any speakers.  If you are careful, your speakers should be fine.
