OPERATION

1
To prevent loud switching noise, first switch on the connected signal sources.
2
Prior to the first switching on of the speaker system, turn down the LEVEL controls to the left stop
position to avoid a high volume at the beginning. Then switch on the speaker system with the power
switch. The POWER indicator lights up.
3
Use the LINE/MIC input selector button to switch the input of models 212A and 215A to microphone or
line level according to the signal sources connected.
4
Adjust the desired volume ratio with the LEVEL or SUB LEVEL controls. Only turn up the controls to
such an extent that the sound reproduction will not be distorted. The LIMIT indicator lights up when the
signal level is too high so that the level limitation will be activated. If this indicator lights up frequently,
reduce the volume of the input signals accordingly.
5
Adjust the high and low frequencies in the main mix with the equalizer controls HI and LOW of models
212A and 215A. If needed, it is possible to attenuate the high frequencies with the HF TRIM selector
switch.
6
If a subwoofer and a top speaker are operated in parallel via the subwoofer's line output, frequency
separation can be adjusted via the LOW PASS control. By doing this, the efficiency between top
speaker and subwoofer can be balanced.
7
If multiple speakers are operated in parallel, phase displacement between the speakers can lead to
performance and output problems. To compensate this, the phase of each speaker can be switched
from 0° up to 180° with the PHASE selector switch.
8
When operating the speaker system, please make sure that the loudspeakers always sound well. When
distortions can be heard, either the amplifier or the loudspeakers are overloaded. Overloads can quickly
lead to amplifier or speaker damage. In order to avoid damage, please reduce the volume immediately
when distortions can be heard. When speaker systems are destroyed by overload, the guarantee
becomes void. Always check the sound pressure level with a meter in order to keep to the threshold.
9
After operation, set the level controls to the left stop position, then switch off the unit with the power
switch. The power indicator extinguishes.
