HI-end remote controllable power amplifiers

The demands placed on modern power amplifiers are enormous: maximum output, minimum weight, the highest possible degree of efficiency, outstanding audio characteristics, absolute reliability, remote supervision and remote control as well as network capability.

To realize stable outputs of 2500 W / 4 Ω and 3500 W / 2 Ω per channel, power amplifiers must be capable of making available peak output voltages of 180 V to 200 V. This requirement limits the number of

topologies meriting consideration to two concepts only: Class D and DYNACORD’s Linear Grounded Bridge Class H. Linear Push-Pull concepts with Class H topology are proven solutions for power levels up to 1500 W / 4 Ω.

This is the approach adopted by many DYNACORD power amplifiers. The limitation of the Class H push-pull approach is the 250 V specification of typical audio power transistors and their second breakdown restrictions. Even exceeding the specified peak voltage or the

second breakdown limit for short periods leads directly to a failure of the power transistors and the power amplifier. The use of exotic 350V-specified transistors affords no reliable solution in view of their second breakdown behaviour, their performance and also their availability.

Higher power classes require different solutions! DYNACORD‘s linear Grounded Bridge designs (e.g. L2400 / P3000) have proved extremely reliable over many years as well as outstanding in terms
