3.13 AX16 - Intelligent Amplifier Switch
3.13.1 General Information
The AX16 is an Intelligent Amplifier Switch that is capable switching both, 100V and high power low-
impedance amplifiers. A faulty amplifier will be completely replaced with its audio inputs and loudspeaker
outputs. The switching process is microprocessor controlled and takes less than 250 ms.
The control of/by the amplifiers is established via contact closures or the SXL II Control Interface.
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 integrated switch-over and fault detection contacts allow for easy communication with any control and
monitoring system.
If connected to a Bittner Audio SXL II via data port, the AX16 will become an essential part of the Bittner
Audio network for intelligent remote control and monitoring.
