Flexibility
Every system comes with different requirements and every customer has his own preferences. Because
of this, the structure is made as flexible as possible.
This is achieved by an input selection matrix. Each of the input connections can be patched to any amplifier
channel and contains software controllable gain. The different implementations of the in- and output
connectors allow the easiest way of connection for every application, while allowing signal link through
to other amplifiers.
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
precautions 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 configuration and control functions, giving limited
(Eg: only volume) control access to standard users and full configuration 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 configured and is indicated in Watts. When the output limiter is configured 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
volume access) going over the limit. This can help you to keep the system compliant with imposed
regulations and maintain the good relationship with the neighbors.
Efficiency
The switching mode power supply and Class D Amplifier technology in combination with the auto-standby
mode for each separate amplifier channel brings an end to the era of the power-hungry amplifiers. In
addition, these features also result in a lightweight amplifier which benefits the customer when used in
mobile applications.
