Filtre pour Power Block Plug'N'Play et micro actif

To achieve high levels of efficiency, the power block adapts its operating frequency according to the load.
As active microphones and boosters have very low power consumption, the operating frequency of the power block may arrive in the sound spectrum.
The filter eliminates any risk of residual noise that may be generated at this operating current (<400µA).

The filter is useless for conventional preamplifiers. In fact, their consumption is generally between 0.5 and 3mA, and the Power Block's operating frequency is then greater than 20kHz.

Operation and installation are described in the diagram.

The filter is available in 3 versions:

A010- Power Block Plug'N'Play filter for active microphones - wire output

A011- Power Block Plug'N'Play filter for active microphones - 1 connector
Pre-wired with a standard active microphone connector.

A012- Power Block Plug'N'Play filter for active microphones - 2 connectors
Pre-wired with 2 standard active microphone connectors.
