Explanatory Note on Specifications 30
The Sensitivity of a loudspeaker specifies the sound pressure produced in a free-field room at a dis-
tance of 1 meter from the loudspeaker if 1 watt electric power is 'transformed' in the speaker.
Additionally, a further sensitivity value is given referring to an input signal of 2.83 volts.
The Nominal Impedance of your loudspeaker normally is 4, 6 or 8 ohms.
Minimum impedances in ohms are given together with the corresponding frequency
The Recommended Amplifier Power is given as a range. The lower limit can be recommended only if
it does not exceed a moderate volume too distinctly.
The correct Mains Voltage, measured in volts, is necessary for a proper function of your appliance and
is provided by your local power authorities. The mains voltage might vary between the given values.
The Power consumption, StandBy specifies the power consumption, measured in watts, which is
drawn out of the mains, when the appliance is connected to the mains but not switched on.
The Max. power consumption, full output specifies the power, measured in watts, which is drawn out
of the mains when the appliance works with maximum output levels.
The Max. amplifier power of an amplifier is also measured in watts and specifies the power which can
be reproduced by the amplifier without any disturbances, like humming, noise or distortions. It is differ-
entiated between the sine power and the pulse power. The sine power describes the power which the
amplifier can reproduce for an endless time theoretically, the pulse power is even higher and specifies
the power for short term signals which can be handled by the amplifier without distortions.
The signal to noise ratio (S/N (A-weighted)) describes the relation between the wanted signal and not
wanted signals like noise or humming. Normally it is measured in dB and is weighted with a curve
called "A"-curve which describes the sensitivity of the human ear.
The Input sensitivity is measured in volts normally and lets you know the input voltage which is
needed to drive the amplifier to full level.
The Input impedance is the AC resistance, normally measured in kilo-ohms, which represents the
load for the driving pre amplifier.
For reproduction of the whole frequency range satellite speakers can be plugged into the Outputs.
