4DXV Series
Exceeding Expectations.
Its revolutionary Class D concept provides a superior combination of efficiency and endurance. Without any loss, even during continuous operation.
The 100 V floating direct outputs lower a lot more than just the weight: Installation and rack prices will drop significantly. And to round this off, the cost for energy consumption will average at roughly one third of any ordinary amplifier.
In addition: In case of a loss of power, the amplifier will automatically switch to 24 V battery power – without any loss of output power!
Sequential power up and „Alive“ relays included. No doubts – a real Bittner!
