The PF 46 is the latest noise canceling filter from the Power Studio brand. Based on the great success of the classic PF 32, the new PF 46 has been developed and studied on 2 axes. Weight reduction and acoustic improvement of the foam. The all new PF 46 is completely made of aluminum, making it ultra light and thus promoting its transport. On the other hand, it also has a new acoustic foam which is very effective against noise pollution during recording. Its installation is very simple and quick thanks to its adjustable system.
