Connections
ELLA is an active loudspeaker-system. The main amplifier is integrated in the loudspeaker and has been
adapted for it. Therefore the loudspeakers have connections for mains power and the signal. The signal cable
has to be connected to the output of the preamplifier or the integrated amplifier. Sometimes also CD-Players
have variable preamplifier-outputs. Please refer to the manual of the device.

For the best sound, the preamplifier should have a balanced layout or at least balanced outputs (XLR-Plugs). It
should also have a sufficient Voltage Output (max. 24V Peak to Peak) to get the maximum sound pressure
level.
The balanced technology has several advantages:
The signal cable can be as long as needed for optimum placement of the loudspeakers without losses.
The Conductors (+ and -) are seperated and shielded. Balanced technology means that the + and the - Signal
are amplified separately. In the receiving device (the main amplifier) only the difference between the signals is
amplified and therefore any disturbances are filtered out. This operation doubles also the amplitude of the
signal which doubles the slew rate of the signal. The sound is more dynamic and clear.
If the preamplifier has no balanced output you can use an interface plug or a XLR-Cinch signal cable .
Sometimes also the output voltage of the preamplifier can be increased. Please refer to the
manufacturer/distributor of the preamplifier.

We recommend using our signal and current cables. They have angled plugs what allows the loudspeakers to
be positioned close to a wall. Our signal cable has a special construction with 4 conductors which are
connected crosswise for an additional protection against disturbances.
We deliver the cable to order in any length you require.

When all connections have been made, the devices can be switched on. Please switch on first the preamplifier
and then the loudspeakers. The loudspeakers must not be switched off after use because the power
consumption is low.
For additional comfort and to save energy, all devices should be connected on a switchable power strip. It is
preferable to use power strips which are protected against lightning strikes.
