AUDAC SMA Series User Manual

SMA&SMQ - User manual 05
Protection
Optimal protection is not only required for the listeners satisfaction, but can also be important for complying
to the imposed regulations and guaranteeing the lifetime of the equipment. Because of this, protection pre-
cautions are implemented in different ways.
Firstly, user access is made possible on different levels. The device can be blocked or accessed in user or
administrator level. Different levels allow different conguration and control functions, giving limited (Eg: only
volume) control access to standard users and full conguration control to administrators. User restriction
can be enabled & disabled and is given through password and / or USB-key.
Secondly, equipment protection is implemented by an output limiter which monitors the output power of
every channel and will intervene when the output exceeds a certain level. The corresponding level can be
software congured and is indicated in Watts. When the output limiter is congured at the maximum power
of the loudspeaker, you can rest assured that the speakers won’t be blown during your absence.
Lastly, the maximum volume for every channel can be set independently. This prevents users (having volu-
me access) going over the limit. This can help you to keep the system compliant with imposed regulations
and maintain a good relationship with the neighbors.
Efficiency
The switching mode power supply and Class D Amplier technology in combination with the congurable
auto-standby mode for each separate amplier channel brings an end to the era of the power-hungry am-
pliers. In addition, these features also result in a lightweight amplier which benets the customer when
used in mobile applications.
