Like all components from the AVM 30.3 series, the MA 30.3 mono power amplifiers also refer to a legendary predecessor, the M3. The M3 Class A/AB mono power amplifiers of the time are still considered one of the sonic highlights in amplifier construction - worldwide. It all started in the mid-1980s with developments that ultimately led to the M1 and the founding of AVM in 1986. The M3 then replaced the M1 in the early 1990s and was built in various evolutionary stages until 2011. To this day, these excellent-sounding power amplifiers are the most frequently built mono power amplifiers from AVM. With the MA 30.3, the 14th generation of the famous AVM power amplifiers is now available - all the experience since 1986 has flowed into this evolutionary stage.

The MA 30.3 also have a great legacy in terms of sound. The M3 provided the template for its modern descendant, the MA 30.3. Essential features such as the structure of the MOS-FET output stages around the colossal main transformer have been retained and modern features such as the intelligent remote switch-on have been added. Extensive innovations from the award-winning large AVM power amplifiers of the OVATION series were also introduced in the MA 30.3 in the circuit design. These innovations are made possible by the use of state-of-the-art components such as those found in our flagship power amplifiers, the SA & MA 8.3. All in all, this resulted in new and ultra-modern mono power amplifiers that play at the highest level of sound.

All functions of the MA 30.3 are automated (protective circuit, etc.). In addition, extensive setting options are available with which the switch-on modes can be selected (automatic, trigger, permanent on). With the AIR (AVM Intelligent Remote) function, the power amplifiers can be easily switched on and off by current AVM preamps (e.g. PA 30.3, PA 8.3, etc.) without the need for a separate trigger cable. The required control signal is simply transmitted via the RCA or XLR cable.

The perfectly crafted housing made of painted sheet steel provides the stable basis to safely carry the huge main transformers and the sensitive electronics. The brushed aluminum front is borrowed from current devices in the EVOLUTION series as well as from the AVM original monos. Standard case versions are silver and black.

The new AVM 30.3 series will make its debut in autumn 2020. Like all AVM devices, the MA 30.3 have also been completely developed in AVM's premium manufacturer in Malsch, Baden, in order to adapt the latest switching methods of the award-winning components from the OVATION and EVOLUTION series into the AVM 30.3 transfer series. Repeated, intensive quality controls during all production steps and a running-in period of several days for each individual device ensure AVM's promise of maximum reliability in the long term.
