Operation Manual
Compact Amplifiers with/without DSP or DANTE Interface
Our new compact amplifiers from the PA-SERIES are intelligent 2-channel power amplifiers in ¼ 19
inch format with output powers of 50 to 200 watts per channel.
The PA-S model range includes versions with and without DSP or DANTE interface.
For optimal adaptation to dierent signal sources, the inputs are designed as RCA sockets as well as
symmetrically. The DSP versions also have an optical 2-channel SPDIF input or a DANTE interface,
which is combined with the 4 x 2 DSP matrix to get managed.
The analog models can be remotely controlled via VCAs and remote ON/OFF contacts, the DSP versi-
ons are configured with our browser-based LB AUDIO CONTROL App and controlled with network
commands, e.g. via media controls.
The circuit design is designed for very high sound quality and longevity with minimal energy con-
sumption and low heat generation.
The processor-controlled power amplifiers deliver the nominal output power stably to load impe-
dances from 2 ohms.
In Auto On/O mode, amplifier channels that are not currently in use switch to an energy-saving
sleep mode. Further features include LEDs for standby/power, sleep, signal, limit and protect, a
ground lift switch to avoid ground loops and DIP switches to switch the input sensitivity.
The devices are manufactured in Feldkirchen/Munich and enable optimal maintenance and service
thanks to their modular design. We oer a 5-year guarantee for all amplifier models.
