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 input connections allow the easiest way for connecting in 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 the maximum
level. 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.
