7. TROUBLESHOOTING

If the sound cannot be heard,
• Make sure that the Power Supply is
connected to the amplifier and the
power is turned on (Green LED stays on)
• Make sure that the amplifiers volume
level is not at its minimum level
• Make sure that all the cables have
been connected correctly and the
media player is turned on and it is
functioning properly. If the media
player has it´s own volume control,
make sure the volume has been set
at sufficient level
If the sound volume is too low,
• Make sure that the signal cable's
D-sub9 connector is properly
connected. Use connector screws
to ensure the successful connection
• Make sure that the media player´s
volume level is set higher
(still adjusting the amplifier´s volume
level to an appropriate level, so that
red LED doesn´t turn on)
• Please note that the media player´s
output capacity affects the amplifier´s
final audio output

8. MAINTENANCE

The Sound Shower is turned off by
disconnecting mains power by removing
the power supply unit from the mains
socket. Notice that disconnecting the
power plug from the loudspeaker does
not disconnect main power from the
power supply unit. The Panphonics
Sound Shower does not need periodical
maintenance.

9. AUDIO ELEMENT

All Sound Showers are based on the
Panphonics Audio Element. The Element
is an electrostatic transducer. The way it
is manufactured, however, places it to
entirely different category compared to
traditional electrostatic loudspeakers.

9.1 Technical description

In the element, a membrane vibrates
between two surface layers, the so
called stators, in coherence with the
input audio signal. The whole input signal
is fed to the entire element area, no
frequency or spatial filtering is included.
Operation of the element is based on
porous structure and its permeability to
air. The element can be covered and its
surface can be patterned applying
various materials or techniques. In all
cases, the air permeability requirement
has to be met.
Do not unnecessarily bend or otherwise
stress the element. Pressure can be
applied on the element surface only at

areas 5 millimetres or less from the
edges. Do not cut, pierce or otherwise
dismantle or mechanically damage the
element structure without first asking for
specific instructions from Panphonics
technical support.
The maximum power handling capacity is
frequency dependent. The table below
shows the maximum signal voltage that
can be applied to the element. Note that
this voltage may damage the element. An
adequate safety margin should be applied.
The element is a capacitive load to the
driving amplifier and operates with a
special adapter or special amplifier only.
It has no magnetic components and
does not generate magnetic fields when
in use. After operation, the bias voltage
remains in the element for 30 seconds.
When used without a short-circuiting
system for unloading the bias, one should
not remove connectors before that time
for safety reasons. CE-approved audio
elements have a safety area of 6 mm on
the edge of the element. On this area
there is no audio signal or electricity.
