The L E N AES / MADI / ASI ground isolator uses a broadband high-pass filter to provide complete galvanic isolation of DC currents between two pieces of equipment, whilst permitting the full bandwidth of the digital signal to pass, thus avoiding problems of signal distortion and operator shocks caused by a voltage difference. This method out-performs broadband transformers for these digital signals. Additionally, some broadband transformers invert the signal, which is incompatible for use with ASI. Both the signal and ground paths between equipment are isolated, there is no distortion of the signal.
There are three types with different housings; one type has an encapsulated enclosure which may be rack-mounted with an accessory panel, one is an in-line 'barrel', without a mounting flange and the third is an in-line 'barrel', with mounting flange.
The LAMF01 is for use with the AES, MADI and ASI standards. It is built in an ABS enclosure fitted with two female BNC connectors. Two M3 mounting screws are provided on the same face as the connectors, so that the filters can be mounted flat to a panel, with the connectors protruding through it.
