PMG1000-V
1000 W, Class ‘D’ GaN Amplifiers

Class D amplifiers, equipped with a modern GaN (gallium nitride) technology, which provides high performance in terms of efficiency and space-saving. The main innovation relating to the use of this cutting-edge technology in the field of PA audio applications is the extreme speed and the ability to operate with high voltages main feature of these new cascode devices; this provides to design amplifiers capable of operating at 300 volts with frequencies of 400 kHz and at the same time – despite the extreme operating conditions – to obtain better performance than those of the equivalent silicon components, which have the limit of working with lower voltages. With these devices, it is also possible to have a 100-volt transformerless output line with a single amplifier (not two bridge amplifiers, as happens instead for silicon devices).
The PMG1000-V amplifiers allow testing correct operation and checking the soundness of the loudspeaker line and a double output circuit with separate controls (A and B) for creating systems featuring line redundancy; if a short-circuit is detected on one of the two outputs, this line is automatically disconnected to enable proper operation of the other.
These amplifiers, connected directly to the CR8506-V controller by means of CAT5 shielded cable, can be used to create high-power areas. 

PMG1000-V model consists of four amplifiers capable of delivering 250 W each; parallel connections can be made in five different modes by setting dedicated switches on the rear panel.
