Acapella Violon 2001 Instruction Manual - Power Connection
Power connection
Before connecting the loudspeaker for the first time, please check all
components in your system for correct polarity of the AC mains. Correct
phase is marked on the ACAPELLA ion tweeter. Please keep an eye
on the red-marked side of the AC-connector. AC mains phase should be
there.
To prevent failures due to condensation, please allow the device to
acclimatise to room temperature before attempting to make connections
to the AC mains outlet.
This eliminates the opportunity of high voltage surges within the oscillator.
If you have any questions to ask, please contact your dealer or directly us.
Operation
During normal operation the ion tweeter does not require special service.
It starts automatically after the first incoming musical signals.
The device will start working as follows: The signal at the input exceeds
the pre-set voltage value (30mV/1lHz). An internal generator begins to
oscillate and a built-in frequency counter in the input stage is collecting
the number of the waves. If this number exceeds the pre-set value, the ion
tweeter will be activated. This procedure is essential to minimise sensitivity
to interference pulses in the power supply mains caused by electrical
appliances such as refrigerators etc. During the start-up procedure of the
ion tweeter, power supply to the arc will be doubled for approx. 2 seconds
to enable the combustion chamber to warm up quickly and to burn dust
particles which were eventually penetrating. This process is bound to
produce more attrition and should not unnecessarily be performed.
A shut-off delay of approx. 20 minutes provides continuos operation
during short pauses (resp. when going below the minimum level). After
longer pauses (more than 20 minutes) or at very low levels, you should
bring the ion tweeter into the „manual“ mode by using the „automatic -
manual“ switch.
