AMPLIFIER
PENAUDIO’s Charisma has a nominal impedance of 8 ohms (minimum 7,9 ohms) that is
easy load for the amplifier. The sensitivity of the loudspeakers is quite low, so more power is needed
especially in wooden structured, spacious rooms. The power recommendation of the amplifier is 30 –
200 W.
How does a loudspeaker get broken?
When amplifiers with low power seem too inadequate for the listener, the usual mistake is to turn up the
bass and treble. This magnifies the amplification ten times higher concluding in the over strained
amplifier to feed distorted signal into the loudspeakers, and ultimately burning the loudspeakers.
Another mistake is to adjust the power too up when the source of the program is a cd player. The cd
player usually reaches its’ peak at the half way of the power density of the amplifier. If the power is still
raised the elements of the loudspeakers will be damaged.
HOME THEATRE
With five PENAUDIO loudspeakers create a high quality home theatre sound world in your home. Your
newly purchased loudspeakers can act both as main and surround speakers.
Five loudspeakers create new challenges in the positioning so again it is reasonable to spend some time
on finding the correct locations.
The surround loudspeakers are often compelled to be placed near the wall which usually affects the
sound. Low frequencies tend to emphasize and the midrange and treble may be distorted. The same
problem is created by placing the center loudspeaker on top of a large television.
The problems are preventable. Low frequency level can be turned down by adjusting a tight plastic foam
plug into the loudspeakers` reflex port. Midrange and treble are easily adjusted by placing and heading
the loudspeakers in a different way. Even a small change in the position can create a great difference in
the sound.
GUARANTEE
PENAUDIO - loudspeakers come with a two year worldwide guarantee including work and material. The
guarantee does not include breaking due to mistreatment.
BURN-IN
PENAUDIO Charisma acquires approximately 20 hours of burn-in time to fill in the specifications. The
time is taken by the element hanging to reach the motion deviation measured in the reference
loudspeaker. Also the caps and wiring need the time to reach the operation level they are meant to
have. The breaking in can be done during normal listening of music. Critical listening tests should be
carried out after the 20 hours.
