AX16 - Intelligent Amplifier Switch
3.8.1.
General Information
The AX16 is an Intelligent Amplifier Switch that is capable switching both, 100V and high power
low-impedance amplifiers (2-16
Ω
). The switching process is microprocessor controlled and takes
less than 250 ms.
To maintain the volume of the system in case of a backup, the input levels are controlled through
digital potentiometers and stored. As a result, the levels/volumes of all amplifier channels will
remain at their set value.
If the AX16 is connected to a Bittner Audio SXL unit, the so-called Intelligent Switching Algorithm
will be activated. This algorithm transmits not only channel levels but also all parameters of an
integrated DSP to the backup amplifier.
The AX16 may also be used as a stand-alone switching device for other brands. The control is
then established via contact closures. The integrated switch-over and fault detection contacts
allow for easy communication with any control and monitoring system.
If connected to a Bittner Audio SXL via data port, the AX16 will become an essential part of the
Bittner Audio network for intelligent remote control and monitoring.
Possible configurations:
˜
Switching of 14 amplifier channels
to two backup channels (7:1)
˜
Switching of two groups of six amplifier channels
to two backup channels per group (3:1)
˜
Switching of four groups of two amplifier channels
to two backup channels each group (1:1)
Max. breaking capacity of each loudspeaker relays: 20A / 250V peak (or 100V for 100V
loudspeaker systems).
